I've managed to successfully build my first electronics project since the light box I built back in Industrial Arts class in Junior High school.
After seeing one of these Morse code key kits at the Dragon*Con ham radio table I helped out with, I decided they were pretty cool and that I should try to build one. Just the thing I need to help me learn and practice Morse Code/CW.
It's a pretty simple kit without a whole lot of components. Everything's all made up, so it's just a matter of sticking the right electrical bits into the proper holes and soldering them into place. It's been a long time since I soldered anything. I practiced a little bit on some old laptop power supply parts I had laying around, then went to work on the kit. The inexpensive soldering iron I picked up at Radio Shack a while ago did an ok job, although it seemed like it took a while to heat things up enough to melt the solder. Fortunately the solder stayed in the places I wanted it to be and I didn't make any short circuits.
I also put my Cold Soldering iron to work on a few parts, which actually worked reasonably well while the tip lasted. Because of the gap it uses in the soldering tips, the cold soldering iron works fine for large things, but is ineffective for small soldering jobs.
Total time was maybe 2-3 hours. If you're good at soldering, it's something that could easily be assembled in an hour or less. My soldering isn't great, but everything works. Kind of tempted to get another one...maybe lay it all out on a breadboard and experiment with modifying it.
