Would you be able to update the prices remotely? The flux on the prices has been crazy for a while now.
It calculates the price every 15 seconds and updates the QR code with the current price of soda in bitcoin.

Relay/monitor is all set up. Program runs flawlessly. All that is needed now is to install in the soda machine. That may be tomorow if I get time. I'm buying a 2nd soda machine and have to drive 2 hours to go pick it up tomorrow. lol
Updated to v0.3
Added dynamic QR codes, they now change to include the current price of a soda. Now all you have to do is scan the qr code and hit send on your phone. Simple.

Still waiting on the rest of the parts to hook it up to the soda machine.
In the mean time I made a Litecoin version
Say Hello to Litecoin Soda Machine v0.1

Post pics of it in action when ready
I will.
I have another project I want to do after the soda machine is up and running.
I want to take an old dollar bill changer I have, install a thermal printer and a raspberry Pi and when $1 is inserted it calculates the current exchange rate and prints out a paper wallet. Or I could skip the paper wallet all together and add the raspberry Pi camera and have it read the qr code on your phone and send how ever much $1 is in bitcoins at that time.
This way people can load up their bitcoin wallet on their phone to use on the soda machine. lol

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.
Check out the video of Bitcoin/Litecoin Soda Machine v0.2

I started a project earlier this week to make a soda machine accept Bitcoins, then I figured what the hell and made it accept Litecoins as well.
The system consists of a Raspberry Pi, a 7" LCD and a relay circuit.
The program on the Pi checks the price of bitcoin/litecoin and the balance of its wallet once every 10-15 seconds, I haven't decided on a set time yet. I may change it to 5 seconds, it doesn't speed up transactions much lowering the refresh time tho, just more work for the 700mhz Pi CPU lol
It currently takes between 10-60 seconds to vend a soda, waiting 1 minute to get a soda may seem like a bit of a wait but it takes over 30 seconds on less than 20% of all transactions so far. The majority of transactions are under 30 seconds.
The QR codes are dynamic and change according to the price.
I'm at the stage that all I have to do is install it in my soda machine. I'm waiting on the rain to let up and I will be doing just that. I will post a video for all to see when its complete later today.
Here are some screenshots for you to drool over.
Let me know what you guys think, I'm always open for input.
