Greetings all; I cleaned the apron up after machining holes for some pushbuttons, washed it up with alky, and gave it a coat of some primer magic that claimed to be etchant and primer. Recoat time was 10 minutes or 48 hours, so I gave it 2 coats. Let it dry long enough to go get some headlight cleaner from Dollar General and apply it to the slowly yellowing OEM headlights in our 2007 Toy Rav4. Looks a lot better. I'd picked up two rattle guns of higher temp stuff, one was too light a grey so I tried the darker one. Darned stuff was actually aluminum and very sparkly looking, and it had cracked the primer, making it look baked on, so I gave it 3 light coats of the lighter grey at 5 minute intervals, supposedly 1200F stuff. Too white by quite a bit, but we're not building a cathedral here either. Waiting for that to cure, I modified the pipe holdowns I put on the saddle to corral a 3rd piece of .375 OD SS pipe, then cut the ends off a 14 foot cat5 jumper I sourced from staples and strung it thru the conduit on the back of the bed to the joint in the middle, thence into the cable chain to the saddle and thru the 3rd pipe. I knew it was a fair piece, but out of 14 feet, I have a foot to spare for hooking it all up on the back of the apron.
Question: For PCW: These pushbuttons have a separately wired led in them. If I can find 2 spare wires in the home switch cable, I could light them up to indicate the wheel is active. But the only note says to apply 1.3 volts. So whats the pullup current capability of a GPIO on the 7i90HD? I think I read only 3.3 volts is available, so thats a 2 volt diff to play with. Can I get 15 to 20 milliamps to run the led? That would mean a 100 ohm current limiter? Or is that in danger of cooking a GPIO? Thanks Peter.
