[USA-NJ] [H] Sager NP8255 Gaming Laptop, 2 x 2GB DDR2 RAM, 2 x Make: Raspberry Pi Starter Kit [W] PayPal, Bitcoin, Google Wallet

Hello again, /hardwareswap. I'm in sort of a money struggle and I need to get rid of some things quick.
Item Price
2 x 2GB Samsung PC2-6400 800MHz DDR2 RAM $12 per stick
WD Green 1TB 3.5" Hard Drive (WD10EZRX) $40
2 x Raspberry Pi Starter Kit $80 per kit
The DDR2 hasn't been used. It's just been laying around my house for a while. The WD Green was an Amazon error, so it's still brand new in the antistatic bag. The Raspberry Pi Kits are also brand new. I definitely need to get this stuff sold by Monday, so PM me if you're interested.
I'm also selling my baby; my Sager NP8255 purchased from XoticPC. Here's what she's filled with:
Sager NP8255 (Clevo P157SM)
Case Matte Black Finish w/ No Branding
Camera Built in 2.0 Megapixel
Battery 8-Cell Li-Ion
Screen 15.6" FHD 16:9 Matte Super Clear Ultra Bright LED Anti-Glare w/ 95% NTSC Color Gamut 1920 x 1080
Fingerprint Reader Integrated
CPU Intel Haswell Core i7-4700MQ 2.4-3.4GHz
RAM 16GB DDR3 1600MHz (2x8GB w/ 2 Free Slots)
GPU NVIDIA GeForce GTX 770M (3.0GB) GDDR5 (MXM Upgradable)
Keyboard 3-Zone RGB Backlit Non-Chiclet
Memory Card Reader Internal 9-in-1 Card Reader
mSATA 2 x Crucial M500 120GB CT120M500SSD3 (Can be RAIDed)
SATA 2 x Seagate Momentus XT 750GB Solid State Hybrid Drive ST750LX003 (Can be RAIDed)
ODD 6x Blu-Ray Burner + 8x DVDRW/CDRW Super Multi Combo Drive
Network Intel AC7260 A/AC/B/G/N 2.4/5.0GHz w/ Bluetooth 4.0
I wish I could get around $2,000, but please feel free to PM me some offers. I can probably buy a Windows 8 key with student discount if you want it installed on there, ready for Windows 10 upgrade. I'm trying to sell this by June 20th.
Edit: I was hoping to just get offers and just pick someone, but I seemed to scare everyone away. Did a Google search, and found that GenTechPC sells this model configured with the same specs around $2,000 new. I was originally expecting offers around the $1,500 to $1,800 range though, which I still think is fairly reasonable.
Edit: I guess I'll come back to sell my laptop another time, when I've figured out a reasonable price to part with it. I still need to sell the other stuff, so it would be much appreciated if somebody wanted any of the other stuff listed above. This was quite the learning experience, and all comments are much appreciated.

Any other new and exciting things that will help with the nitty gritty of being a proper bitcoin user
Will a Raspberry Pi 4 suffice for all these at once? How much hard drive space will I need? how much RAM should I get. Apperently I'll need an SD card as well?
Is there any particular kit that is worth getting or should I assemble it piece meal? I know nothing about this, so really any suggestions/advice would be greatly appreciated

Where can you actually SPEND dogecoins? [Please Add on]

When trying to explain dogecoin to people for the first time, the #1 question I get is "Yeah but, can you actually use it to buy things?"
One of the major things that will take Dogecoin to the moon will be people actually using the Ð. For a currency to gain legitimacy, it's got to be spendable. The good news is, there are sites popping up that take the Ð! Some sites also list other sites that take the Ð and serve as directories. Considering how great this community is and how quickly we are growing, the number of transactions and using Ð as real money could really make the difference!

Best $100-$300 FPGA development board in 2018?

Hello, I’ve been trying to decide on a FPGA development board, and have only been able to find posts and Reddit threads from 4-5 years ago. So I wanted to start a new thread and ask about the best “mid-range” FGPA development board in 2018. (Price range $100-$300.)
I started with this Quora answer about FPGA boards, from 2013. The Altera DE1 sounded good. Then I looked through the Terasic DE boards.
Then I found this Reddit thread from 2014, asking about the DE1-SoC vs the Cyclone V GX Starter Kit:‬ (I was also leaning towards the DE1-SoC.)
Anyway, I thought I better ask here, because there are probably some new things to be aware of in 2018.
I’m completely new to FPGAs and VHDL, but I have experience with electronics/microcontrollers/programming. My goal is to start with some basic soft-core processors. I want to get some C / Rust programs compiling and running on my own CPU designs. I also want to play around with different instruction sets, and maybe start experimenting with asynchronous circuits (e.g. clock-less CPUs)
Also I don’t know if this is possible, but I’d like to experiment with ternary computing, or work with analog signals instead of purely digital logic. EDIT: I just realized that you would call those FPAAs, i.e. “analog” instead of “gate”. Would be cool if there was a dev board that also had an FPAA, but no problem if not.
EDIT 2: I also realized why "analog signals on an FPGA" doesn't make any sense, because of how LUTs work. They emulate boolean logic with a lookup table, and the table can only store 0s and 1s. So there's no way to emulate a transistor in an intermediate state. I'll just have play around with some transistors on a breadboard.
UPDATE: I've put together a table with some of the best options:
Board Maker Chip LUTs Price SoC? Features
icoBoard Lattice iCE40-HX8K 7,680 $100 Sort of A very simple FPGA development board that plugs into a Raspberry Pi, so you have a "backup" hard-core CPU that can control networking, etc. Supports a huge range of pmod accessories. You can write a program/circuit so that the Raspberry Pi CPU and the FPGA work together, similar to a SoC. Proprietary bitstream is fully reverse engineered and supported by Project IceStorm, and there is an open-source toolchain that can compile your hardware design to bitstream. Has everything you need to start experimenting with FPGAs.
iCE40-HX8K Breakout Board Lattice iCE40-HX8K-CT256 7,680 $49 No 8 LEDs, 8 switches. Very similar to icoBoard, but no Raspberry Pi or pmod accessories.
iCE40 UltraPlus Lattice iCE40 UltraPlus FPGA 5280 $99 No Chip specs. 4 switchable FPGAs, and a rechargeable battery. Bluetooth module, LCD Display (240 x 240 RGB), RGB LED, microphones, audio output, compass, pressure, gyro, accelerometer.
Go Board Lattice ICE40 HX1K FPGA 1280 $65 No 4 LEDs, 4 buttons, Dual 7-Segment LED Display, VGA, 25 MHz on-board clock, 1 Mb Flash.
snickerdoodle Xilinx Zynq 7010 28K $95 Yes Xilinx Zynq 7-Series SoC - ARM Cortex-A9 processor, and Artix-7 FPGA. 125 IO pins. 1GB DDR2 RAM. Texas Instruments WiLink 8 wireless module for 802.11n Wi-Fi and Bluetooth 4.1. No LEDs or buttons, but easy to wire up your own on a breadboard. If you want to use a baseboard, you'll need a snickerdoodle black ($195) with the pins in the "down" orientation. (E.g. The "breakyBreaky breakout board" ($49) or piSmasher SBC ($195)). The snickerdoodle one only comes with pins in the "up" orientation and doesn't support any baseboards. But you can still plug the jumpers into the pins and wire up things on a breadboard.
numato Mimas A7 Xilinx Artix 7 52K $149 No 2Gb DDR3 RAM. Gigabit Ethernet. HDMI IN/OUT. 100MHz LVDS oscillator. 80 IOs. 7-segment display, LEDs, buttons. (Found in this Reddit thread.)
Ultra96 Xilinx Zynq UltraScale+ ZU3EG 154K $249 Yes Has one of the latest Xilinx SoCs. 2 GB (512M x32) LPDDR4 Memory. Wi-Fi / Bluetooth. Mini DisplayPort. 1x USB 3.0 type Micro-B, 2x USB 3.0 Type A. Audio I/O. Four user-controllable LEDs. No buttons and limited LEDs, but easy to wire up your own on a breadboard
Nexys A7-100T Xilinx Artix 7 15,850 $265 No . 128MiB DDR2 RAM. Ethernet port, PWM audio output, accelerometer, PDM microphone, microphone, etc. 16 switches, 16 LEDs. 7 segment displays. USB HID Host for mice, keyboards and memory sticks.
Zybo Z7-10 Xilinx Zynq 7010 17,600 $199 Yes Xilinx Zynq 7000 SoC (ARM Cortex-A9, 7-series FPGA.) 1 GB DDR3 RAM. A few switches, push buttons, and LEDs. USB and Ethernet. Audio in/out ports. HDMI source + sink with CEC. 8 Total Processor I/O, 40 Total FPGA I/O. Also a faster version for $299 (Zybo Z7-20).
Arty A7 Xilinx Artix 7 15K $119 No 256MB DDR3L. 10/100 Mbps Ethernet. A few switches, buttons, LEDs.
DE10-Standard (specs) Altera Cyclone V 110K $350 Yes Dual-core Cortex-A9 processor. Lots of buttons, LEDs, and other peripherals.
DE10-Nano Altera Cyclone V 110K $130 Yes Same as DE10-Standard, but not as many peripherals, buttons, LEDs, etc.


icoBoard ($100). (Buy it here.)
The icoBoard plugs into a Raspberry Pi, so it's similar to having a SoC. The iCE40-HX8K chip comes with 7,680 LUTs (logic elements.) This means that after you learn the basics and create some simple circuits, you'll also have enough logic elements to run the VexRiscv soft-core CPU (the lightweight Murax SoC.)
The icoBoard also supports a huge range of pluggable pmod accessories:
You can pick whatever peripherals you're interested in, and buy some more in the future.
Every FPGA vendor keeps their bitstream format secret. (Here's a Hacker News discussion about it.) The iCE40-HX8K bitstream has been fully reverse engineered by Project IceStorm, and there is an open-source set of tools that can compile Verilog to iCE40 bitstream.
This means that you have the freedom to do some crazy experiments, like:
You don't really have the same freedom to explore these things with Xilinx or Altera FPGAs. (Especially asynchronous circuits.)


Second Place:

iCE40-HX8K Breakout Board ($49)

Third Place:

numato Mimas A7 ($149).
An excellent development board with a Xilinx Artix 7 FPGA, so you can play with a bigger / faster FPGA and run a full RISC-V soft-core with all the options enabled, and a much higher clock speed. (The iCE40 FPGAs are a bit slow and small.)
Note: I've changed my mind several times as I learned new things. Here's some of my previous thoughts.

What did I buy?

I ordered a iCE40-HX8K Breakout Board to try out the IceStorm open source tooling. (I would have ordered an icoBoard if I had found it earlier.) I also bought a numato Mimas A7 so that I could experiment with the Artix 7 FPGA and Xilinx software (Vivado Design Suite.)


What can I do with an FPGA? / How many LUTs do I need?

Easiest guide to setting up a Bitcoin full node with a Raspberry Pi?

Hey guys,
I’ve been contemplating utilizing the remaining 500GB of data I don’t use in my monthly plan by running a Bitcoin full node. However, as I’m not code savvy, I’ve been procrastinating.
I’m thinking of going for it by purchasing a Raspberry Pi kit and 1TB external HDD but am looking for a ‘friendly’ guide to help.
Can anyone recommend a user friendly guide to setting up a Bitcoin full node with a Raspberry Pi? Or even if it’s possible for someone to set up and maintain who isn’t fluent in code?

The chatlog from #lightning-network discussing recent Lightning DDOS/vulnerability

bitPico [5:49 PM] If any LN testers see their connection slots full it’s us. We will release the attack code when ready. The network needs better protection against DDoS’s. (edited)
Laolu Osuntokun [5:59 PM] ? or report to specific implementations @bitPico? like the early days of bitcoin, don't think many impls have even started to start to cover dos vectors busy working on safety in other aspects
bitPico [6:00 PM] As it stands no implementation can handle connection exhaustion attacks by overflowing the underlying TCP stack.
Laolu Osuntokun [6:00 PM] not sure if any limit inbound connections yet
bitPico [6:02 PM] Doesn’t matter; we use the TCP half-open attack. This occurs at the kernel.
Laolu Osuntokun [6:02 PM] sure you'd still run into fd limits so that's not really impl specific
bitPico [6:02 PM] Yes; we exhaust the FD’s. (edited)
Laolu Osuntokun [6:04 PM] you could do the same for any active bitcoin node today, nodes would need to set up network-level mitigations unless the impls were super low level enough to detect something like that so would really depend on their default kernel settings
Matt Drollette [6:10 PM] echo 1 > /proc/sys/net/ipv4/tcp_syncookies … ?
bitPico [6:14 PM] Our Bitcoin implementation performs round-robin disconnects to induce network churn. This is one of the best methods to prevent most TCP attacks. Churn is needed in decentralized systems. It keeps them robust. Longstanding TCP connections are bad. *ie we disconnect N nodes every T mins.
Laolu Osuntokun [6:18 PM] if it's half open, how are you detecting the TCP connections then @bitPico? well for LN the connections are typically long lived @mdrollette yeh, defenses are at the kernel lvl
bitPico [6:21 PM] Round-robin disconnects free the kernel FD’s. There is also App level half-connect Works like this Syn Ack But don’t sent the Ack The connection is then half-open TCP connect scans work like this. TCP half-open scans are harder to detect.
ɹɑd [6:33 PM] Is there a way to tell lnd to listen on ipv4 instead of ipv6? When I try lnd --listen= ..., it is listening on IPv6 TCP *:9735 but I need it to listen on IPv4.
Matt Drollette [6:34 PM] I think if you give it a specific IP instead of it will only bind to that specific interface
ɹɑd [6:34 PM] ok, trying that…
bitPico [6:36 PM] Dual-stack OS will still open IPv6 Windows and Linux are VERY different TCP stacks. The behaviour is different.
ɹɑd [6:38 PM] Nice, that worked. Thanks, @mdrollette
bitPico [7:13 PM] How does LN protect from “dead end packets”? ie* onion wrapped but final destination doesn’t exist. aka routing amplification attack
kekalot [7:14 PM] :trumpet::skull:

bitPico [9:00 PM] We are most interested in our “route payload amplification” attack vector. This attack onion wraps payloads via hop by hop where the last hop is the first hop creating a self-denial of service where the LN nodes attack themselves after long route traversal. Exploiting the anonymous nature of onion routing allows no defense to the network. Anonymous routing in and of itself creates a situation where the network can get into an endless loop of self DDoS. Once we complete the entire message serialization routines and a deadline timer the TESTBED will run standalone continuously. Prob. only take another day to complete that. We are also making attack vectors as base classes so new ones can be easily created via overrides. *ie plugin-like attack vectors
Russell O'Connor [9:22 PM]
bitPico [9:26 PM] Yes; that idea and our attack vector(s) makes the entire network fall apart. We will prove this works. (edited) When nobody trusts nobody the network collapses. Low level attacks requiring no fees are easier however. (edited) There is nothing to prevent spoofing via replay of older packets. Because onion routing requires decryption (CPU Intensive) this can also be used to clog pathways with old payloads via CPU exhaustion. (edited) This is the real reason why ToR is so damn slow; it’s constantly attacked. It has nothing to do with end users actions.
Matt Drollette [9:34 PM] GitHub Switch Persistence [ALL]: Forwarding Packages + Sphinx Replay Protection + Circuit Persistence by cfromknecht · Pull Request #761 · lightningnetwork/lnd This PR builds on #629, and integrates the changes with my more recent work on forwarding packages and batch-replay protection provided via pending changes to lightning-onion repo. Save one or two ...
bitPico [9:40 PM] (#)761 doesn’t impact our AV_03 It does however cause nodes to use more CPU and possibly go to disk per the notes. If LN nodes must go to disk this is bad. The slowest code pathways make the best AV’s.
bitPico [9:52 PM] CircuitKey’s are allocated “on the heap”. (edited) Underlying implementation would use malloc/realloc/free. Instead of RAII. This is asking for an overflow into unknown memory segments. We suggest stack only allocation. Memory on the stack is trivial to maintain; it has no holes; it can be mapped straight into the cache; it is attached on a per-thread basis. Memory in the heap is a heap of objects; it is more difficult to maintain; it can have holes.
Laolu Osuntokun [9:59 PM] @bitPico cpu usage is super minimal, this isn't tor so we're not relaying like gigabytes unknown memory segments? golang is a memory safe language stuff goes on the stack, then escape analysis is used to decide what should go on the heap
bitPico [10:00 PM] Heap allocation is more of a concern here. golang is not memory safe; it uses C underneath.
Laolu Osuntokun [10:01 PM] uhh
bitPico [10:01 PM] golang is not written in golang :slightly_smiling_face:
Laolu Osuntokun [10:01 PM] yes it is... GitHub golang/go go - The Go programming language
bitPico [10:02 PM] That’s like saying the C runtime is C and not ASM. The C runtime is ASM.
Laolu Osuntokun [10:02 PM] go is written in go before go 1.4 (maybe 1.5) is was written in c but still, your "attack vector" isn't an implementation level issue, it's a network/kernel level DoS recycling, syn cookies, etc, would be needed not impl level defenses (edited)
bitPico [10:07 PM] We know the answer but what does golang compile to?
Laolu Osuntokun [10:07 PM] also replay htlc's will be rejected native?
bitPico [10:08 PM] ASM
Laolu Osuntokun [10:08 PM] yeh...
bitPico [10:08 PM] So what we said is exactly true.
Laolu Osuntokun [10:08 PM] no?
bitPico [10:08 PM] It’s as vulnerable as we stated.
Laolu Osuntokun [10:08 PM]
the heap is a heap of objects; it is more difficult to maintain; it can have holes
bitPico [10:09 PM] It still allocates through OS heap memory and not onto the stack in your case here. Which means it has holes.
Laolu Osuntokun [10:10 PM] aight, lemmie know when you exploit these issues in the golang runtime here's the code if you wanna study it: GitHub golang/go go - The Go programming language
bitPico [10:11 PM] ASM is ASM. Heap is heap. Heap is bad in this case. Stack is wise. Same applies to C or C++. Avoid the heap at all costs.
Laolu Osuntokun [10:12 PM] aye aye, capt
stark [10:12 PM] replied to a thread: Seeing bad OP-SEC on LN; don’t name your node as the type of hardware. Those raspberry pi’s will go down. don't name your node at all....
bitPico [10:12 PM]
Laolu Osuntokun [10:13 PM] cool, i'll be waiting on those exploits in the go runtime, i'm sure many others will be excited as well
bitPico [10:14 PM] Has nothing to do with go. It uses malloc underneath. Heap always uses malloc; go, c or c++ or java or whatever.
Laolu Osuntokun [10:15 PM] sure, i think many of us know how memory management works
bitPico [10:15 PM] Security experts avoid heap allocation. This is common knowledge. Noticed somebody commented about performance of the PR. That is because of the use of heap allocation instead of stack.
Laolu Osuntokun [10:17 PM] no, it's because of the disk I/O
bitPico [10:18 PM] So LN nodes write data to disk in case of crash? As to not lose funds? That’s what the PR says. Anyway golang uses libc; it is not compiled into pure ASM. (edited) Nevertheless we are not focusing on golang; LN in general and TCP/IP stacks.
ɹɑd [10:22 PM] @bitPico write an exploit and get back with us. Until then it just sounds like concern trolling.
bitPico [10:24 PM] Funny, we are exhausting LN TCP/IP Stacks as we type this… It’s no good if we can overtake the TCP stack and run it out of FD’s. We have 100's of connections to LN nodes and it;s automated using our hand built attack toolkit. When we increase this to 1000's then what?
Matt Drollette [10:26 PM] Isn’t that true of any TCP service though? Or are you saying there is something Lightning or lnd specific about your method?
Laolu Osuntokun [10:26 PM] it's true of any TCP service the defenses are on the kernel level
bitPico [10:27 PM] You’d need to have LN code handle millions of connections to mitigate this. We know golang will crash if this happens. But so will C.
Matt Drollette [10:29 PM] I’m beginning to wonder if @bitPico is actually performing a meta-attack on Lightning. A denial-of-service at the developer level with all this subtle trolling
bitPico [10:29 PM] This first problem is LN keeps inbound connections alive. It does not handle and drop them like a webserver. This is the only reason webservers can scale. Apache uses a timeout of 3 seconds in most cases. Currently we are connected to 45 LN nodes with over 22K connections. One variable change on our end and the network will suffer. (edited)
Matt Drollette [10:31 PM] but is that variable on the heap?
bitPico [10:32 PM] On Linux consider forcing it to require 999999 FD’s. AND do not keep-alive connections. The variable is an enum (an integer). Attack aggressiveness
Matt Drollette [10:33 PM] I’m just joking with you :stuck_out_tongue: I look forward to the write-up on the attack
bitPico [10:33 PM] Otherwise our code will keep LN nodes hung in TIME_WAIT. Anyway we are not trolling; we are BTC whales and LN must not fail. Otherwise our investment suffers. The only motivation behind this testing… As it stands LN nodes need L7 LB. Code will run overnight; sleep before we continue. Good job though on LN so far.
bitPico [10:46 PM] uploaded and commented on this image: Screen Shot 2018-03-19 at 1.44.19 AM.png
Fun stats: We’ve sucked 3.3 GB’s of bandwidth per hour from LN nodes. This will continue while we sleep. Every 80 milliseconds there is 44 attacks being performed.

I’m thinking of running a Bitcoin full node but need a little advice please.

I believe in the future of Bitcoin. I find the whole space exciting and have been accumulating small amounts of BTC for about a year now, pretty much during the bear market.
I only recently started really looking into how I can contribute to this space but can’t afford the expense of mining (I don’t have the funds for the equipment or the electricity).
However, I have a 1TB data plan at home but only average around 650GB per month of usage. So I’ve been looking into contributing to the Bitcoin network by running a full node.
My laptop is not an option, but I’ve read I can run a full node using a Raspberry Pi and as I’m not very techy, actually I’m not techy at all, I’m looking for a little advice.
  1. If I were to purchase a Raspberry Pi kit, considering my level of technical knowledge, how likely is it that I could setup a full node at home?
  2. Does the node need regular maintenance? Or does it more or less just do its thing once it’s setup?
  3. I am accumulating my BTC on my Ledger Nano S. Can I keep using my hardware wallet and just run a node separately? Or should I use the node as my wallet?
Thank you for any help you may be able to offer!

[thought experiment] two years ago Theymos and Core divided the community with their outright rejection of larger blocks. Had folks invested in BTC instead of Raspberry pis, they could afford the feared "$20K fullnode" today and we could have gigabyte blocks and global onchain scaling today.

It was roughly two years ago that the Bitcoin community faced the worst attack in its history: the splitting of the community and ousting of all "large blockers."
As a thought experiment, let's suppose that instead of purchasing Raspberry Pi "full node" machines (cost of kit + SSD = ~$275) these people had instead purchased Bitcoins two years ago when they were $225 ea.
Today, all these Raspberry Pi node-runners could afford a highly-scalable "$20K node" of the sort that would be required today if Bitcoin had already achieved global adoption like we originally were hoping.
We can conclude as a matter of abductive reasoning that these people may well hold more wealth in Raspberry Pis than they ever did in Bitcoins.

if you think the 21inc bitcoin computer is a waste of money because of ROI, i believe you're missing the point

i keep seeing posts about people being upset because they can't understand why someone would pay $400 for a raspberry pi with a mining shield, a big ass heatsink, and a fan. this isn't marketed as a bitcoin mining device. it's being marketed as a device (a dev kit for future devices, at this point) that is designed to integrate with bitcoin in many ways. mining is one (and definitely not the only one) of the ways it does that. and it's not mining to just be mining.
i'm not super familiar with the ins and outs of this newfangled device, but it seems to me like the satoshis are for other uses, like smart contract kinds of uses. the things are definitely not mining for profit.
i don't get everyone's obsession with ROI. would you be considering the ROI if you were investing in any other computer? obviously a computer is an investment, but the value you get out of it is from its utility. you can do all kinds of crazy cool shit with a computer. things you never imagined you could do before. i recently got a raspberry pi, and the uses seem endless. i never thought i would be learning about linux, coding, web design, electronics, robotics, music, web servers, home servers, proxys, radio, graphic design, and home automation, all because of the same little device! i don't see anything keeping this 21inc device from being a great tool for bitcoin innovation on many levels. and it seems they're just getting started.
it also seems to me like 21inc will eventually have a very decentralized mining pool. plus, the existence of another mining pool adds decentralization to bitcoin mining in general. right?
perhaps someone who is more knowledgeable could elaborate or cmv?
tl;dr the 21 inc computer is not a mining rig. it's a computer. it does stuff. some people find value in that.

Bitcoin node on Raspberry Pi Zero W

Hi guys, just thought I'd comment that I have just been able to get a full node running on a Raspberry Pi Zero W, with a 1TB external hard drive. Here's the tutorial I followed, if anyone else is interested.
Cost: £37 for Raspberry Pi Zero W - Mega Kit with Zebra case + 1TB hard drive I had laying around (probably bought it for about £50 at some stage).
Could be done much cheaper, but since I wasn't sure it would work for a bitcoin node, I got the mega kit and case in the event that I'd end up using it for something else.

The 8 most informative comments about 21inc's bitcoin computer dev kit

"Anyone who thinks this is about making money by mining has very little insight into what Bitcoin actually offers the world. This is not about bringing the old economy (banks, businesses, governments) into the Bitcoin family. This is about building entirely new economies, ones that have never and could never have existed before. 21inc can see the vision and they just bootstrapped the IoT on the Bitcoin blockchain. Thank your lucky stars on your way to the moon." - PhiMinD
"I'm fairly sure this is NOT an end user device. This device appears to be solely for the purpose of prototyping integration with other devices, and allow people to work out the ends and outs of the process. My assumption is that in like 6 months to a year, a much more compact and integrated device will be released that would be far cheaper, and suitable for installation in actual consumer devices. This is for developers." - DakotaChiliBeans
"The more I think about it, the more incredible and groundbreaking this seems. When every piece of hardware and software has the ability to transfer money, our entire concept of how we do everything changes. We're only beginning to imagine the possibilities. Even the few simple ones I've been thinking of make my head spin. Bitcoin as a human currency is exciting. Creates a more open system, breaks monopoly, gives you the option of true, non-revocable ownership. All great stuff. But it's these revolutionary ideas that make me believe that Bitcoin, or a successor very much like it, will take over the world. As someone invested in bitcoin, I'd like to see it succeed and my investment pay off, but goddamn will this be an exciting ride regardless. At this point, I'm seriously thinking of buying and developing on it. The potential here is lightyears beyond what most people are thinking." - consideranon
"Seeing the 21 Bitcoin computer reminds me of the developer kits for oculus rift. It took a lot of time to perfect before going fully public. It was also tested with a pre-release through Samsung's VR headset. Other more resourceful people bought the cardboard much like the same people would buy the Raspberry Pi instead of this. Anyway, the 21 computer is very likely the first iteration of many." - Hiro_Y3
"I think it removes a step in the process. Instead of learning about wallets, private keys, maintaining a login and password, etc, the computer takes care of all of that without the user having to think about any of it. The mining function provides initial liquidity to get the ball rolling. This is the first step of payments being built into the IoT." -TDBit
"Most of everybody here is missing the point. This is a bitcoin computer. This is not made to simply mine to generate a profit but rather a miner is just an added part. The miner is used to continuously supply the Bitcoin computer with bitcoin. It uses the bitcoin to "write" to the blockchain. It's like a digital quill with an endless bitcoin inkwell." -Fuzzypickles69
"Ok, this takes a leap of faith, but what they're trying to do is build a full-stack device which can send/receive bitcoin and which also solves the "how do devices get bitcoin in the first place" problem. Imagine the whole thing being a lot smaller and cheaper, and embedded in lots of devices globally. Now you have a world in which millions of devices (machines) can send and receive tiny payments, and which natively have a currency unit to use for that purpose." - melbustus
"ServiceXYZ: Links your 21 box to your Twitter account, and any paywall website lets you read anything you want without popups, ads, or subscriptions. There, I just made up a business in 10 seconds, someone go make it :)" - evoorhees

Rasberry Pi Full Node

i have a Pi 3 kit coming and i'll be using it to set up & run a full node (bitcoin). for now I plan to use my TV as a monitor and the included mini wireless keyboard that came with the kit to get it all set up. i have a 32 gb class 10 microSD card for the OS (i learned i can have multiple operating systems on the Pi) and a portable 250 gb external ssd for syncing/storing the entire blockchain on. once i'm all set up with my bitcoin node which i intend to let run basically 24/7, am i going to have enough space/processing power left over on the Pi to emulate games or stream movies? i assume I'll still be able to smoothly explore everything raspberry has to offer whilst running my node?
i plan on using my laptop to download the blockchain to the external SSD because I'm told it takes quite awhile to download via Raspberry. am I going to run into formatting issues if I first plug in the SSD (its a new Samsung T5) into my laptop and then plug it into the raspberry?

FOR IMMEDIATE RELEASE: After Butterfly Labs collapses, engineers find new jobs at 21 Inc.


After Butterfly Labs collapses, engineers find new jobs at 21 Inc.

A bitcoin miner has shipped on time. Yes, that is news. A new venture-capital backed company, 21 Inc., has released a miniature bitcoin miner that they call a "Bitcoin computer". For $399.99, you get a Raspberry Pi, an SHA-256 ASIC board, and a giant fan.
Again, this is news: normally, a manufacturer of bitcoin miners would overdesign and underengineer their equipment, or, if they managed to ship something functional, it would be so poorly engineered -- and over budget -- that it be an explosion waiting to happen and/or priced comparably to a four-door sedan.
21 Inc. has done something remarkable in the Bitcoin world: they started a company that operates like a legitimate business. They're even listed on, a company that's so strict with vendors that Nintendo was kicked off their system for not kissing enough customer ass.
Okay, enough with the praise.

This thing sucks.

The "computer" certainly deserves a place in the VC world, along with the other products consisting of wild promises and inane use cases. For the price of 4 Raspberry Pi computer kits, you get the following:
(If you have a remote desire to develop applications that use bitcoin, stop here. Go through that list and buy just those items above. You don't need anything else. If you're looking for comedy, or if you're a sucker with too much money, read on...)

Is that all I get for my money?

Those products alone don't allow you to make Bitcoin applications, apparently. You need these things, too:

How about the software demos?

It's difficult to justify developing a $400 computer that can't do much. So, to entice some customers, 21 Inc. included demos that try really hard to make customers feel inspired. Here are just a few things that 21 Inc. claims were totally impossible before their product existed:

What are the real customers saying?

The packaging is slick:
"This @21dotco computer came already opened..."
The hardware is reliable:
" must have lost power, which caused my SSH keys to become corrupted."
The software is revolutionary:

[hardware] quick check - is this enough to build my own raspberry pi full node?

Hi, just a quick check so I am not forgetting something. Will this be enough to build my own raspberry pi node from scratch? If I am forgetting something or someone has recommendations for bettecheaper hardware, please let me know :)
