It was quite fun to solder and mount this kit. An hour at about 3 evenings and all worked well. The most complicated thing was the first step, the soldering of the brass axes so that everything was in line …
The description is good, a magnifying glass helped, too. One 1kOhm resistor was a 1% type instead of 5%, but you realize that in the end, a multimeter helps also. A resistor was changed to an inductor, that was mentioned in the by packed paper.
At the end I used hot-glue instead of instant-glue to fix the ping-pong ball. The whole mechanics is rather simple, probably not meant for precision applications, but it’s cool with a real prototype feeling 🙂
Now the software part is the next thing, I’m curious ..
