      Do any of you guys know anything about process?

      I’ve been doing some digging into the QRCode functions again and have come across OpenBitcoinQRConvert.pde It sounded like it might be the answer to my problems so after a little digging I discovered that I could just open it with a text editor…

      The 1st couple of lines say the following

      // Convert image to a C header file suitable for the Adafruit_Thermal library.
// This is NOT an Arduino sketch.  Runs in Processing IDE (www.processing.org)

      So it looks like it is the file I’m looking for, I have tried downloading from processing.org, and following the some what cryptic instructions to get this to work but I’m failing…

      I have a web server sitting on a Pi that is dealing with the address to QR creation, can anyone point me in the right direction to get this running on the same web server so I can use it to generate the required hex for the private keys easily

      UM

        After a lot of digging I think I have the answer :)

        #define 0wB0
#define 0hB0


static {
  0xFF,0xFF,0xFF,0xFC,0x03,0xFE,0x01,0xFF,0xF0,0xFF,0x80,0x00,0x00,0x1F,0xFF,0x00,0xFF,0x80,0x7F,0xFF,0xFF,0xFF,
  
other random lines that look like they might be right
  0xFF,0xFF,0xFF,0xFC,0x03,0xFF,0xE0,0x0F,0x0F,0x07,0x80,0x3C,0x00,0x1E,0x1F,0xF0,0x07,0xFF,0x80,0x3C,0x00,0x00,
  0xFF,0xFF,0xFF,0xFC,0x03,0xFF,0xE0,0x0F,0x0F,0x07,0x80,0x3C,0x00,0x1E,0x1F,0xF0,0x07,0xFF,0x80,0x3C,0x00,0x00
};

        Problem is I’m not going to be in front of the ATM to test it until tomorrow afternoon :(

        But if I’m right we are all systems go, will be getting the drawing finished tomorrow night and then they will be off to the laser cutter later this week.

        Now to cosmetics…

        Does any one have a preference on the colour of the box? lol

        UM

          Feathercoin colours IMO. Perhaps even including the pcb style wiring decals.

            This is great. I’m thinking how cool would it be to make a cash machine that works the other way round.
            Send your FTC and you get Cash!

            Considering the recent hassles with gox and the general inability for mere mortals to convert FTC to cash I think this machine would be a good partner for your invention.

            Cash to FTC and FTC to cash. There’s a business there for someone!

            It would certainly help your oxford blue landlord cash out in order to buy more barrels of beer or any other high street merchant for that matter.

            I think there’s a need for this on the street, it’s one thing accepting feather coins but if you want to pay your supplier in FIAT it’s a different matter. A nice mod would be that the FIAT value is transferred to your account via BACS ( possibly by inserting a bank card?)
            I’m sure you guys have thought of this already.

              On second thoughts
              It’s one machine with the ability to do either!

                OK, It looks like the QR issue is solved, but I have a couple of errors in the code…

                The logo file gets deleted after the 1st print comes off

                I don’t get a log file written to the SD card

                Any help guys?

                      Changed the code to resolve the logo issue now, just working on the log file bit.

                      Might have a slight problem with what happenes when the SD card is empty of QR codes thou as the coin taker doesn’t have an enable pin. So might have to make up a small circuit to cut the power to the coin taker once the card is spent.

                        Just use a single channel relay, cheap as chips.
                        I can send one after the weekend when I’m home from Greece if that helps.

                          I’ve got a couple here, but thanks for the offer :)

                          I’m not seeing anything in the code to drop pin3 to ground thou but I may be missing it.

                          I have the log file sorted now that I have added a statement to call it that was missing. Just need to look at the RTC as the date is rubbish!!

                          I also need to work out how to get the modified code onto Github as I have no idea about that, if nothing else comes of this I can say I have learnt a fair bit :D

                            I suspect that the RTC is the problem with the logfile, as it’s logging data just not what I was expecting from reading the code

                            This is the output

                              This is so sweet guys… Truly epic… If we can have a working prototype to show the world during the 1 year anniversary, it could get a lot of attention.

                                @Calem I’m hoping for more than one by then :)

                                This should be good to go before the next meet up just need to find some one to do the sticker printing as I only have access to powered coaters so its going to look very boring

                                UM

                                EDIT *** 500 posts :) ***

                                    @prensel, thanks man… I’ve just Skyped iawgoM about that artwork but he’s not on-line yet…

                                    Can you do vinyl stickers with a spot gloss finish? something similar to this? as I think the circuit tracks would look very cool in gloss :) then all I need to do is think of a colour for the can, but that maybe limited to whats in the spray gun at the time of taking it in due to the time constants of getting it ready for the end of the month

                                      RTC problem is now fixed, I get a log file that makes sense…

                                      Next thing is shutting down the taker when it runs out of codes, I don’t mind that it keeps swallowing £1 coins but the punters might get a little feed up of it. I’ve just been to the cupboard where the parts are kept to get a relay and there is none in there, I can’t remember using any… will have to pop out again later and get a couple

                                        Current casing design is this…

                                        casing_1_zps140be832.jpg

                                        Vertical slot is for coin taker, horizontal slot is for printer, hole on the end is to take a standard PC PSU…

                                        Thoughts? This is ready to go off to the laser cutters, and due to time constraints to get it ready for the OB at the end of the month, I need to push the button tomorrow lunch at the latest
