Merry Christmas Mark! Switch and diode testing: 1. Test all the switches once they are installed in the panel. For extra points for the paranoid, test them before installing in the panel too. But a visual inspection for broken or loose parts is usually all that is needed then. You want to test after installing in the panel in case case distortion is going to make the switch fail. 2. Run the wires from the switches and diodes off to the termination area, but don't terminate yet. Bundle and tie loosely, occasionally, and only if absolutely necessary to preserve sanity. These cable ties will come off and be replaced later, so don't sweat them. 3. Once everything is loosely wired, strip the termination ends of the matrix wires, and start testing. Since wires are still loose it is pretty easy to fix any mistakes. 4. Once everything is verified, pretty up and lace the wiring. 5. Make the end terminations to connectors or screw headers or whatever. 6. Double-check that you got the wires in the right place on the end termination. 7. Once the controller is live, run a software check to be sure that everything is correct. It doesn't hurt to do a double-key check on a few selected keys, like joystick down while pressing some other button. Make sure results are as expected. I'm sure you already knew 90% of that, but you did ask... :-)

Hi Mark Merry Christmas ! What a great package from Roel ,that chuck will make things so much easier. Since you asked about component testing👹 at my old job we would check every wire ,resistor,switch,motor,etc for its important parameters before use and then check again after soldering ,crimping or whatever we did to it . Of course we were building a nuclear reactor inspection tool, so there certain standards to live up to. A few of my co-workers had worked for P&W ,needless to say they had the same sort of standards as well. There is nothing nicer that tidely done point to point wiring and lacing. PCB's are obvious for volume work , but for one off or custom why bother? Finally thank you for providing us with our Sunday morning entertainment.

An addendum/unsolicited idea. in an earlier episode you super glued the switches to the printed frame. Now that i've seen the switch pcb's I see that there are diagonal screw holes. would it be an idea to remake the frame so that all switches are on pcb's and screwed to the printed frame instead?

I wouldn't worry about brand new signal diodes not working. As far as semiconductors go, they're extremely simple devices - just as long as you don't manhandle them to the point of breaking the glass they should be fine. A very nice assembly, the only concern about not going the PCB route is potentially vibration cracking the solder joints but you've made nice mechanical connections before soldering so everything should be fine long term. Incidentally, when I was taught to solder by my Grandfather who was a radar tech in the RAAF (and later continued as a civilian contractor to the RAN), I wasn't allowed to put the iron anywhere near the work until the mechanical connection was good. I image he would've been pleased to see the way you've done it!

If your interface does not need you to press more than one button at a time, you don't need diodes on every switch. Regular computer keyboards do not have them. You can test this by pressing more and more keys simultaneously: you will find that some combinations allow you to press quite a few before pressing more keys has no effect. Gaming keyboards (as well as other gaming controllers like gamepads) use either an oversized, sparsely populated matrix which is cleverly designed to allow any ten keys to be pressed at once or have diodes.

We work on them one bit at a time, and always check your power supply/section. Measure each component in any signal chain not working, see that it's as expected, move on. (Skipping ahead is allowed, but then skip back if you got weird results at the goal) Working in halves, 1/4, 1/8ths and similar divisions is also a good idea just to narrow down and exclude faults faster. Can be very difficult if you don't have schematics etc.

And all the matrixed wiring is only part of the job, then you have key mappings and potential issues with double keypresses (ie; hold down one key while you press another). Good luck!

Oh, I guess the wiring on the boards will be right, but might have screwed up on the hand wired ones. Double key presses are not a big issue on a CNC controller, at least that is my experience with the Maho, where I didn#t even use diodes. You dont really type much, just press single function buttons. The 7i73 automates some of the firmware set up, but there will still be one line of assignment code per key.

To clarify, given a chunk of memory, finding item x in an array of items is easy. ItemX = MemoryBase + (ItemSize * Index). The Intel x86 CPU has an instruction that does this exact thing for accessing arrays. If it started at one, you would have to account for that. It also is better for loops because of several reasons.

I bought a 100 pack from Amazon. Hope they are good. I did test a few and they seem fine.

You could've paid someone to make the pcb layouts for you.
@RotarySMP8 ай бұрын
You are probably right. Problem is that I know so little about that world, that I would not know where to start finding that person, specing what I want done, etc. I remember eagle has a 1/2 euro card limit of PCB size in it's free version, and the commerial one was expensive. This project would either need six or seven boards, or two big wierd shaped ones. And given how much time it took to learn FreeCad, I was not in the mood for learning another software right now.

@@tinygriffy Thanks a lot for the offer. It would have been either two very large, odd shaped PCB's, or seven which still needed a lot of interconnecting, or this. I should have polled you experienced guys wisdom earlier. Sorry about that.
