My new cheap hot air soldering station arrived, along with some solder paste that turned out to be leaded (I forgot to check). Tried it out and holy shit it's like magic! This is a game changer for micro USB connectors.
I tried it out on a pointing stick PCB and it's a big improvement over my dodgy hand soldering. It also saved a board I had written off because it was too much of a pain to fix the USB connector.
Accidentally made a new thread for the pointing stick, so here's the old one: https://mastodon.technology/@gbrnt/105906955241870768
Made a bit more progress on the pointing stick project before I realised I only have one strain gauge left. I did order more but the order got cancelled.
The mod wires went fairly smoothly, although I still hate stripping magnet wire. Haven't checked that they work - that would be a good idea because this mod is likely to be permanently glued on. Perhaps I should use hot glue to be safe.
I also printed and heavily ground away at a new mount for strain gauges.
Major progress on the pointing stick project today! I actually managed to build it into a keyboard!
Started by redesigning the strain gauge mount to clear the keycaps, then printed and assembled it. That went smoothly but took a while.
It turned out the keys I bought are plate mount so they lack the little pegs that go into the PCB! But they'll do - this is just a prototype, the keys aren't the important thing here.
Initial testing feels good but it's late so I'll try it tomorrow!
