Email arrived from LadyAda on Friday.In between the usual advice about good Korean barbecue technique and pointers to cool things that just happen to be conductive, she mentioned that Adafruit have been on a real roll this week with Pi projects.You’ll already have seen Adafruit’s Onion Pi, a Pi-based wireless Tor proxy.Staying within a topical theme, here is Adafruit’s newest Pi undertaking: a Bitcoin miner.If you’re not sure what a Bitcoin is or why this is interesting, head over to read Gizmodo’s explanation (which offers a nice simple breakdown), or look at the Bitcoin Wiki before you go any further.The Pi on its own isn’t an efficient Bitcoin miner; some people are using it as one, but more as an example of how mining works and a bit of a novelty than as a genuine way to raise funds.(If you’re going to be mining Bitcoins, you’ll fall into one of two groups: people who do it for fun and who don’t mind whether they make money or not; or people who take it very, very seriously and approach it as a business.)

What you really need if you’re trying to make money out of the enterprise is a custom ASIC device, which has a much higher hashrate than something like the Pi.And it turns out that the Pi is a very cheap and efficient way to control and monitor devices which are better suited to mining Bitcoins – like the new, thumb-drive-sized ASIC Bitcoin miners that have started appearing on the market recently, which mine at a similar rate to a fast graphics card.Adafruit have a detailed tutorial on setting up the Pi to act as a headless controller and status monitor for your mining devices, with information on uptime, hashrate, error rate, share data, and network difficulty displayed on an LCD screen attached to the whole device.I know several of you are already using Pis to mine, and that others are building FPGA mining platforms with the Pi.We’d love to hear more about how you’re getting on – please let us know in the comments!Computer SkillsElectronicsHow to Create a Raspberry Pi Bitcoin MinerEnvato Market has a range of items for sale to help get you started.

The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin Protocol.It allows you to: Buy digital goods and services with a stream of bitcoin mined by a 21 Bitcoin Chip Sell your digital goods and services for bitcoin with the built-in 21 Micropayments Server Easily build bitcoin-payable apps, services, and devices Operate it as a standalone computer, or connect it to any Mac, Windows, or Linux machine Mine small amounts of bitcoin to facilitate development of Bitcoin applications and to purchase digital goods.See "What is the 21 Bitcoin Computer" below for more details It includes: A command line interface and Python 3 library A 128 GB SD card loaded with a full copy of the Blockchain A suite of pre-configured Bitcoin-dependent software All the items you need to get started - including a WiFi adapter, USB-to-laptop cable, and power supply The 21 Bitcoin Computer was produced with funding from Qualcomm, Cisco, and Andreessen Horowitz.Mine Bitcoin on demand with the 21 Bitcoin Computer.

Then buy and sell digital goods and services at the command line.The 21 Bitcoin Computer is the first computer with native hardware and software support for the Bitcoin protocol.That means the hardware to mine a stream of small amounts of bitcoin for development purposes, and the software to make that bitcoin useful for buying and selling digital goods.Developers use the 21 Bitcoin Computer to quickly add Bitcoin-based monetization to any app, service, or device.Please note: the satoshis you mine provide a source of readily-available bitcoin for application development, but are not intended to be used for investment purposes.bitcoin umsatzYou can use the 21 Bitcoin Computer with your keyboard and monitor as a standalone Linux box, or plug it in to provide bitcoin over the Internet to any existing Mac, Windows, or Linux machine.litecoin asic miner buy

Either way, the embedded 21 Bitcoin Chip gives you a stream of mined bitcoin to use at the command line and in your code.Now you can programmatically interact with the Bitcoin network as easily as you can connect to the Internet.The 21 Bitcoin Computer is ideal for buying and selling digital goods and services.You can use it to create bitcoin-payable APIs, set up your own personal digital goods store, pay people to share your content online, or host online games of skill.ethereum xrpFor example, you can provide translation services for bitcoin, sell your photos online, pay people to share links to your product on social media, or host a game of skill in which your friends win real money.bitcoin difficulty calculatorIn terms of physical goods, you can also use the 21 Bitcoin Computer to rent out any Internet-accessible device on a per-use basis.bitcoin price 1700

So you can allow people to submit paid print jobs to printers and 3D printers for bitcoin.Or you can set up a smart lock that accepts bitcoin to open a door.Because the 21 Bitcoin Computer is a full computer, you can make essentially any Internet-accessible device Bitcoin-rentable.The micropayments server built in to each 21 Bitcoin Computer allows true peer-to-peer commerce.Any buyer can now directly connect with any seller anywhere in the world.As such it’s a tool for both learning Bitcoin, and for becoming an entrepreneur by selling access to your digital goods and services for Bitcoin.bitcoin copper roundsIf you can code it, you can sell it.bitcoin buy in suratDescribe your product in 3 words.cours de l'action bitcoinFirst Bitcoin Computer Where did you get the inspiration for your product?hong kong bitcoin association

We're all about the individual entrepreneur.The Internet meant that everyone became a publisher, even if their full time job title wasn't "reporter".Bitcoin will similarly mean that everyone becomes an entrepreneur, even if they don't quit their day job.The 21 Bitcoin Computer is our contribution to this transformation.What differentiates your product from similar products out there?The 21 Bitcoin Computer allows anyone to sell anything over the internet for bitcoin just by plugging a device into the wall and typing a few commands.We think that is fairly unique.Tell us about the best and most challenging parts of the creation process.It is hard to identify a single most challenging part as this kind of product is just inherently difficult to build.We redefine the concept of a full stack startup as we go all the way down to the silicon layer and build our own chips.As for the best part, we'd be happy if the concepts embodied in this device - including native hardware and software support for the Bitcoin protocol, but extending to the concept of buying and selling digital goods and services for bitcoin - do end up empowering a new generation of entrepreneurs, especially in the developing world.
