i am seeing occasional unintential repeating keypresses, both in 9front and openbsd. seems more frequent the harder i press the keys, almost as if there is some kind of threshold i’m crossing that makes the keyboard think i’m holding the key down.
anyone eeeellllssssseeeeee seeing this?
Yes, this happened to me to. I thought that maybe something was wrong with the switch itself so I de-soldered it which made me see that there was a very tiny bit of dirt stuck in the plastic slid into which a metal spring slides when you press the key down and the dirt would push the spring back a little bit resulting in a second contact, thus a second key press. Since the dirt was stuck at the top of the plastic slit of the switch, this effect happened when I pressed the key very hard and did not happen when pressing softly.
Maybe remove enough keycaps so that you are able to see the affected switch from the side and check if anything is stuck in it. I’ll take a photo the next time this happens to me.
Previously I had increased the keyboard debounce to try and get around this issue happening to me.
But as mentioned earlier in that thread, a real option to try and reflow the solder joins.
Tonight I have gone over and just reflowed every key and it appears to be working better.
My 8 and { keys still double up, so I’ll try to hit those with some extra solder later.
Also the last post in that thread also mentions the debris issue with a little video.
Aha, it’s called the “actuating ramp” – that’s exactly where I had some stuff stuck. Removing it fixed the problem for me but I only saw it once I had the switch removed as reflowing the solder didn’t help.
