A circuit simulator where you draw everything. Wires are pixels, gates are triangles. Design chips, watch signals glow as they propagate, and debug by rewinding time.

"The noblest pleasure is the joy of understanding"
Leonardo da Vinci
Draw circuits like a pixel artist - brush, select, copy-paste - and simulate with 1 button.
Everything is built from a single primitive: the NAND gate. Watch logic propagate in real time.
Little pixel triangles are NANDs.
Black pixels are background.
Everything else is a wire.
60+ levels and growing, ranging from basic gates to memory and arithmetic (in the future cpu's, coding and more!)
Instead of schematics, create complex circuits designing component blueprints, placing + routing them.
Actively developed and fully open source.
