As seen @ DEF CON 2013 – the BitcoinBriefcase is a self-contained Bitcoin vending machine –
Once the user’s last coin is inserted, he pushes the LED button to let the system know to start the Bitcoin magic. A random number is generated using the hardware pseudorandom number generator on the raspberry pi and is used as the private key for this Bitcoin transaction. A transaction for the inserted value is broadcast to the public Bitcoin network, and the transaction information including the private key, the Bitcoin address, and associated QR codes are printed out on the thermal printer.
No doubt every hackerspace will soon be needing one of these. Spotted quite a bit of adafruit gearinside too! 🙂
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
