Abigail O. ★★★★★

Drawing a little keyboard on paper and actually hearing the notes change as I press harder is wild, and the resistance-mapping feature works exactly as promised. I've spent an embarrassing amount of time just scribbling different lines to hear the pitch bend. It's such a fun way to mess around with

Andrew V. ★★★★★

I was skeptical at first, but mapping electrical devices to circuit resistance is actually a fun way to learn about circuits. The built-in speaker that changes pitch with resistance makes drawing a piano feel like real music creation.

Joseph ★★★★★

Getting the hang of drawing a working piano key took a few tries, but once it clicked, the pitch change from resistance is incredibly responsive. I've spent hours sketching out simple songs and it's genuinely fun to hear your own doodles come to life.
