This solder practice kit has an RGB LED and three potentiometers to adjust the color.
After completing Blink I assembled Hue. I used the same Tin-Silver-Copper Kester SAC 305 lead free solder I used for the previous kit.
Here is the kit before assembly:
Here is the assembled kit:
The kit worked. Here is a demo with dials set to isolate green:
Here the dials are set to isolate blue:
Isolated red:
Finally, an example of tuning the dials to get a violet color:
I got yellow too. It didn’t show up well in the photo so I’m not including it here.
Finally, the solder joints:
The leads in the bottom row (for the potentiometers) were the hardest to solder because they are so close together. I was being careful not to bridge them and ended up not using enough solder (the pads are visible). The connections obviously still work since I can adjust all the colors. Otherwise, the joints look similar to the results in the Blink kit. Overall, not bad for my second kit.
