Since I’ve finished my flash trigger circuit, I’ve been trying to get the schematic in the computer so I can share it with others. Minor problem — the circuit capture software I’ve tried has been horrible. Rather than fighting with counterintuitive interfaces or editing text files to fill in support for integrated circuits I need, I decided to go with the tool I know best — Adobe Illustrator.

To that end, I’ve created a symbol library that contains the circuit elements I need — capacitors, resistors, transistors, and the like. Creating a schematic diagram in Adobe Illustrator is now as simple as dragging symbols and connecting them — no fancy illustration skills needed.

The Circuit Symbols library is released under the Creative Commons Attribution-Noncommercial-Share Alike 2.5 license.

Update: I’ve updated the symbols to fit better when using “Snap to Grid”. They’re optimized for a 0.5″ grid with 16 subdivisions.
