Looking for a fun soldering project that does more than light up? The SparkFun Gram Piano Kit will have you singing a happy tune in no time! Once built, the piano’s capacitive resistance keys respond to your touch. Tap one of the eight keys and the onboard speaker will emit the tone. To change octaves, turn the potentiometer. Standoffs make for a simple, balanced keyboard stand. There are lots of resistors included in this through hole kit, so you’ll definitely learn how to read those stripes in addition to upping your soldering skills!
You can buy the kit from Sparkfun for $27.96.
