Last light and early this morning (I've finished at 01:30 AM) I've completed the soldering of electronic components (diodes, Teensy, condenser...)
It looks fine and it was easier than I thought it would be (barring in mind it took me more than 2 hours to finish). There are several things I learned:
- Using paste on non-SMD stuff is a no-no. It's too messy and you need a lot of paste to do stuff. If you don't have the proper dispensing method it's not going to work.
- My solder iron sucks. It sort-of-works, but it has a flat-ish tip and it looks (and feels) like the wrong tool for fine electronics
- Pliers and tweezers are essential
- You can solder wire with the hot air gun. It's cool, but you need an electrical one
I was surprised to see the teensy blinking after plugging in the USB. And, once the firmware was loaded, the device was recognised as a keyboard:
Here's the full keyboard:
Getting inspiration form a testing thread, I've shorted some switch points and... VOILA!
- Picking up switches,
- soldering the switches and leds
