While working on an earlier project (possibly this) something about the regular grid arrangement of components sticking up on a circuit made me think of a chess board. Finally got to executing it as my project-a-month for August.
These are real components soldered onto the perf-board, the sole purpose being to create these images. This is not an working circuit!
Rook: Ferrite Chokes
Knight: Metallised Polyester Capacitors
King & Queen: Electrolytic Capacitors
