A multi-function kit that finishes as a small playable piano. It is a fun, musical payoff that keeps beginners — and kids with supervision — engaged through a full board of through-hole joints.
A musical payoff is a great motivator, and this little piano delivers one cheaply. The sound is no concert grand, but pressing a key you wired yourself and hearing a note come out is exactly the kind of small win that turns a one-off attempt into a hobby.

Contents come from the current Amazon listing and can change — check the listing before buying.
Solder the resistors and small components first, then the key contacts, keeping each one flat against the board — a key that sits proud feels unresponsive later. Test the tones before final assembly. If one key is silent, the fault is nearly always that key contact rather than the sound circuit.
Musical beginners and gift-givers who want a playable result.
Similar price and difficulty if you would rather finish with a small game than an instrument.
A longer, more rewarding build for someone who wants more practice and a playable arcade.
