Open Source ATM
-
There’s a guy called Ronan who’s the Director of Internation Sales at pyramid. I’ve dropped him an e-mail asking about UK distributors. I’ll report back.
-
Kris, thats the idea :)
I’m just drawing the case up in CAD now, bit difficult without the hardware here, but I can get the basics done. As soon as the hardware arrives I’ll get it finished and off to the laser cutters to get it burnt in 2mm steel. When we have it right we can make the files open source as well!

I’ve just emailed them the same question :)
Do you think they will put the price up because of the sudden interest in their product?
-
Haha, now they think there’s a demand, send them e-mail offering to be a distributor.
-
I’m looking at one of these http://shanghai-elan.cn/Download/Download%20files/Lumina%20Datasheet.pdf I think everything we have so far is configured to use a pulse interface, so maybe this will do?
spynappels can you see anything in the code that might allude to how the pulses are counted? and if there is anything that looks like it’s expecting the pulses to come in at a set frequency?
-
We do not have a distributor at this point of time. If you wish to acquire a unit you may buy it directly from us.
-
The pulses are counted at 50ms intervals, with a 2000ms timeout.
-
Given the price of FTC, we could try it with a coin acceptor first, these are cheaper:
Limit it to 50p, £1 and £2 perhaps?
They work on the same principle, using pulses…
-
FYI
A 12 Volt Pulse mode Apex 7000 series with a 500 notes cash box will cost 239 dollars plus shipping, approximately 65 dollars to the U.K.
-
Then the coin acceptor at < £25 is a better first bet!
-
Just come across them.
Looking at the code
const int DOLLAR_PULSE = 4; //pulses per dollarIs it going to be easy enough to add addition lines? for what we want at this point?
I’m in for ordering 1 to go with the rest of the stuff that’s on it’s way, if you think we have a 50%+ chance of getting it to work, I have found a link where people are using the same model with a Ardunio to create a piggy bank, so that sounds promising to me
He’s going to get very suspicious as I’ve just sent him the same question. I’m not fussed about the shipping as if we wait till the end of March I can get one brought back with family. I’m warming to the coin taker version the more I read about it
-
Seconded, it’s an easier route for the first prototype. I linked earlier in the thread to a R-Pi project which uses one of these.
-
I’ve read some more of the code now, and there’s a section for adding additional denominations, so it looks like that may be covered :)
//---------------------------------------------------------- // Add additional currency denomination logic here: $5, $10, $20 //---------------------------------------------------------- pulseCount = 0; // reset pulse count pulseTime = 0; }Spynappels, where about’s in the world are you? I’m going to need to buy you a beer and soon

Quick update on parts for you gents, let me know if you think I’m missing anything
- Coin selector - ordered should be here next week
- A2 Micro Panel Thermal Printer - ordered and dispatched
- Arduino Uno - ordered should be here next week
- Arduino SD Shield and Real Time Clock - ordered and dispatched
- DC/DC (Buck) Converter 12V to 5V 3A - see below
- Resistor 10K - in the shed
- Barrel Plug 2.1 mm - not needed
- Power Supply 12V - going to use an old PC PSU for now, as it give 12v and 5v so no need for the above
- SD Card - on the shelf behind me
Do you guys have any ideas on what you want the finished article to look like? or are you happy to go with a variation of the housing I post a couple of days back?

How are you planning on connecting to the network?
-
Looks good, the Arduino can take 12 volts into the barrel connector, and if you’re using a shield I’d recommend taking a 12V from the PSU to the barrel connector, it’s just easier than trying to bypass the RAW +ve in past one of the shield pins.
Let me know when you get the Uno and I’ll try and talk you through some of the gotchas.
The code will be easy to alter to allow for different denominations of coin, I’ll see if it is easy to change the code so that you don’t get a QR code for every coin inserted, with allowing coins that becomes a little more problematic unless we limit it to only pound coins to begin with.
I’m in Northern Ireland btw, so our coins are the same as yours but we have our own banknotes as well as the Bank of England ones.

First iteration won’t, it will dispense £1 worth of FTC at a set rate, the first iteration is very limited, but as we get it working it can be made more complex. For a live wallet, it will need to be ported to a R-Pi anyway as you’ll not get a live wallet ported to Arduino, and then it can be networked more easily.

Just seamed an easier option than messing around with voltage drop from 12v to 5v and done like this makes the case design easier for world domination as PC PSU should have the same dimensions, and mounting points the world over :)

As soon as it’s here, I will mate I’m really excited about this project and want it of the ground ASAP

So lets stick to pound coins on v1 and then go from there.
What he says about the network connection :)
-
Can’t fault your logic.

Sounds great pound coins is a really good place to start. (Also I have a raspberry pi if we need it for FTC ATM V6?)
