Description: Pianos are heavy and can take about a year to make. What if you could have one that weighed only a few grams and took a very small amount of time to construct? The SparkFun Gram Piano is a beginners soldering kit that, once assembled, gives you with a musical keyboard that will leave you feeling like a modern day Mozart. This kit provides you with the ability to play an octave worth of notes using the capacitive touch keys, no strings or hammers required! The pre-installed software also lets you play a melody with the press of a button and switch octaves using a soldered potentiometer.
The Gram Piano is a simple through-hole kit with a fair part count, making it ideal for beginning solderers looking for a little more challenge. Like our other soldering kits, building and playing with this kit will teach you various skills related to soldering, electronics, and programming.
Note: Be sure to check out the Quickstart Guide in the Documents section below for helpful tips and assembly instructions.

I made this kit for a 3yr old kid, and she loved it!
I was pleasantly surprised when the PCB was bigger than what I was expecting. I did use an IC socket instead of soldering the AVR chip directly to the board. I also used a vertical 6 pin programming header because I did not want anything sticking out from the sides. One thing to note is that there is no reverse polarity protection so make sure you insert those batteries in the right way as indicated.
Two minor suggestions: 1) A louder speaker would have made this more fun (perhaps not for the parents) 2) A hole for a standoff in the middle of the board would help support it better when pressing hard on the keys, but this is easily fixed by gluing on a standoff
Looking forward to the day she hears the built in song somewhere and realizes that she has heard it before.
Thanks for the great review. And good tips for future revisions if we make a new version in the future. Thanks for sharing and happy hacking!
