Open Source ATM

Is this the dimensions?
#define 0w90
#define 0hA0
144 x 160?
-
You working on the logo or the QR code?
-
That’s from the logo file.
-
Looks about right in pixels to me for the BTC logo I have seen on there site.
Without printing something out that size, I can’t be 100% thou.

Ah right yeah £50 is canny expensive but I don’t think I was expecting you to say it would only cost £20 to get the case made. Lol
-
Bit of a cheat mate, I own an engineering company as well as my day job :)
-
Hi Mr Wyrm, that is the dimension of the logo according to the code, the sketch reads those two values and uses them to determine the size of the bitmap.
-
There is another way, I have said in an earlier post just add NFC? The ATM will work great.

Gary we might be able to add NFC in the future but for now we are just going to keep it simple :)
I now have all the hardware with the exception of the coin taker, If I’m feeling up to it I might start putting things together later or tomorrow, But I have taken a beating at work today, that’s going to take a bit to get over.
But I’m sure when I open all the little packets up again and look at the bits it will all come back to me :)

Quick question. How can I test/view this Hex image? Anyone know of a viewer?
-
And we are off…
I’ve been doing stuff, 1st off MrWyrm, I have no idea how we test it other than sending it to me and I’ll see what it looks like on the printer when it’s up and running, but then next point is after I have been messing around with the QRCode generation it looks like a FTC logo has already been generated for us… doh, check things before people start work muddy!
Everything is here with the exception of the coin taker, which is due tomorrow, but I’m not going to be here :( so it maybe Saturday before I get my hands on it, and I have a very busy weeekend again so it could be early next week before I get back onto the project.
I’ve designed out the circuit board so we are not connecting directly to anything and we can maintain all of the original connections so hardware re-use is easy. Hopefully if I get time to run out a little later this will be complete tonight :)
I have redesigned the casing a little to take into consideration that I’m planning on using a very low end PC PSU just because I have a spare here and they are cheep cheep cheep on eBay should we want to make any more, with the any more in mind… I have to make up a minimum order value with the laser cutters of £60 so I could end up with several of these casing up for grabs!
I’ll keep you updated as things progress, but just wanted to let you all know we are still working on this and hope to have it at the next meet-up :)

OK so how do I convert a .png to hex then… confused :-\
-
Check the link I posted up. Start with a two colour TIFF, rename it to a .bin and use the bin to hex converter, then remove the TIFF header.
Fire me your PNG and I’ll see what I can do.

I think the logo.oba is the original BTC logo as the new code mentions logo.ofa
if(SD.exists(“logo.ofa”)){
printBitmap(“logo.ofa”);
-
This is the logo I have found,
I have an logo.oba file, but without printing it I don’t know if it is for the above image
-
git says “23 days ago”, so I’d guess that’s the original. The new logo has different dimensions, so will need a tweak in the code, if it hasn’t already.
Let me have a look at the image and see what I can sort.
-
Where did that logo come from?
-
It’s in with the QRCode generator stuff
https://github.com/mayosmith/BitcoinQRMaker
I set this up today to see if it generated the hex files needed for the printer to produce the private keys, but all it seams to do is generate the QRcodes, a quick browse through the folders and I found that logo
-
I think I have something wrong here my output looks some thing like this

I’m only presuming the image is two colour to be honest, because previous printers I’ve played with had that limit. I’ll have a read over the printer documentation to see if we can handle other greyscale shades.
