    Ahh, I would have thought the same as you. Still reading up.

    Have a look at…

    http://www.ht-lab.com/freeutils/bin2hex/bin2hex.html

    There are ways to convert two colour binary Tif into Intel Hex and it’s pretty well documented. I’m in work, so can’t give it my full attention.

        I saw that the dogecoin guys made something like this using a brief case as the container. In theory this could save us some dosh if we used a security style brief case as it is already easy to open is secure and has a locking mechanism (combo locks?) obviously it would need to be cut into to fit the coin / note reader?

        something like this?

          Fudge me thats expensive. Kris I don’t expect the laser cut blank to be more than £10 to be honest looking at it on the screen here.

          I lock and hinge from somewhere prob no more than another £10, little bit of bending and welding. Job done!

            Is this the dimensions?

            #define 0w90

            #define 0hA0

            144 x 160?

                  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

                        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 :)

                                    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,

                                        feathercoin_zps647f6db5.png

                                        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.
