Colecovision and ADAM Game Pad

Colecovision and ADAM Game Pad Update 13.4.17: Alright, alright, I'm making one last promise - cross my heart and hope to die if I'm wrong... Some further refining of the models Additional options have been added More mock-up images are included to illustrate Update 12.4.17: Another day, another update. This might be the final version unless I decide to add auto-fire capability to the PCB P and B button functions have been added to the PCB - Super Game Controller A new v2 .zip file is available for sending off to a fab house for PCB manufacture As a result, the D_Pad buttons have been reworked Update 11.4.17: I've done a significant rework of this model to make it easier to assemble and hopefully improve the final result Button tolerances have been reworked - sanding to get the fit right is no longer necessary Improved connection between the shell parts, with the addition of clips, for easier fit and glue-free assembly Shell base re-profiled for improved comfort - base will now need to be printed with support Cable grommet added Optional stabilizer for the D_Pad has been added to stiffen its action if required Num_Pad and action buttons have been reworked for a similar goal Some blank Num_Pad buttons have been added in case of printer resolution issues Fire and Arm are now differentiated by a nub on two of the buttons Two alternate D-Pads Extra mock-up images Do you own a ColecoVision game console? Maybe you're even more fortunate and own an ADAM Computer... Great, aren't they? ...did I hear someone say the controllers are a bit sh_t? Yes, you're probably right, maybe not Atari 7600 sh_t but they aren't the most ergonomic of little beasties. Fear not, here's a little something for all those with cramped hands or those looking for a replacement controller and like a bit of DIY. You will need: 1) The included .stl files for printing 2) The .zip file containing the PCB 'gerber' files for sending to a PCB fab house (really easy, I'd recommend Seeed Fusion but there are plenty of others) 3) 20 6x6x4.5mm tact-switches 4) A plop-load of diodes, I'd suggest 1N4148's but most will do. (26) 5) An Atari-type joystick cable, be sure it's got all the pins connected 5) The most basic of soldering skills 6) Some patience It should all go together reasonably easily, just make sure you get all the diodes the right way round (it's marked on the PCB) and you've wired the wires correctly... ...in the latter case I've included the original Coleco schematic and my version of said schematic. The points on the PCB for soldering the cable are arranged the same way as the connector on a controller as detailed in both schematics. I'd strongly suggest not trusting to the wire colours but to buzz them out with a multi-meter... ...space is a little tight as I wanted the controller to be about the same size as a SNES game pad but there's lots of components to fit: -Solder as neatly as you can -Probably best to start with the switches for this one -Cut the pins nice and short -The lower shell has a channel to route the wire and help hold it tight against the PCB -The PCB has a couple of holes near the cable solder-points for a cable-tie Have fun! PS Yes I know a standard Coleco controller only has two fire buttons. Mine has four having duplicated each button... ...partly to give your thumb more places to rest but mostly for aesthetics. PPS There is a commercial game-controller for Coleco Systems that is taking orders: https://atariage.com/forums/topic/289767-announcing-the-super-game-controller-for-the-colecovision/ My pad is intended for DIY'ers.
