http://www.youtube.com/watch?v=U51zvo-HOdgNow all I need to do is wire up a relay from the Pi to the soda machine and attach my 7" LCD to the soda machine.
Once I have a working prototype I can build them for people for a price. It would be a plug and play set up.
PM me if you are interested in reserving a spot in line when I start cranking them out.
No preorders, no money exchanged until I'm ready to ship. (This is subject to change if I get swamped and have to hire workers)
It should work on any soda machine or vending machine that uses dixie-narco or coinco changers, with an 8pin connector, which is almost all of them. If you have a soda machine that is different PM me and I can make something custom.
My first thought was using a Raspberry Pi for the in/out pins and the easiness to add that to python scripts.
The QR code is static but I plan to add a dynamic QR code in the future that will include the current price per soda in the QR code.
It currently gets data from MTgox and a Bitcoin wallet running on one of my mining rigs, and BTC-e and a Litecoin wallet running on the same mining rig.
It looks for 0 confirm transactions and when a transaction comes in that meets or exceeds the price per soda it vends a soda.
I have done my research and have my own vending machine. All I have to do is install a relay to send 120v ac to one of the pins coming from the coin changer and it will dispense a soda.
I have a 7" LCD on its way from amazon that will be my display for the soda machine. It will display exactly what is in the white box in the video.
Let me know what you guys think, I would love some input.
The Relay, LCD, and mini wireless keyboard mouse will all be here Tuesday or Wednesday. I should have the soda machine working shortly after that.
