Build your own Bitcoin ATM

For those of you interesting in cryptocurrencies such as Bitcoin - the following project will be of interest. John Mayo-Smith has created and built a simple ATM that can be reproduced at a reasonable cost (compared to a real ATM) and possibly a lot of fun. The ATM accepts paper currency and dispenses tickets with QR codes representing the required data to claim the Bitcoin.

The Bitcoin data is preloaded onto an SD card, and dispensed as required - an interesting method of keeping "stock" for sale. A quick demonstration of the build and resulting ATM operation is shown in the following video:

if you're interested in how this ATM works or want to make your own, all the required information is found on the project website. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If you're looking to learn how to get more from your Arduino or compatible board in order to make your own ATMs or interface with other commercial hardware, you can't go past "Arduino Workshop -  A Hands-On Introduction with 65 Projects” by John Boxall.

Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more.
