I got a Canon A540 the other week, it’s a great camera. I found this software for Canon cameras, it enables alot of features not enabled by default on Canons including scripts. I enabled USB remote with this script. I then made a little circuit to apply 3.3 volts to the correct wires on the USB port of the camera. Here is a photo of the device taken using the remote.

My Freeduino SB board finally arrived!
Here are some photographs of my soldering job.:


More to come once I write my own program.:
Here is the Ardiuno compatible board that I ordered and shipped today.
Freediuno SB
I will post projects that I do and my learning process. I hope to develop a reader for some punch tape from an old CNC machine that I have. It’s tape with 8 holes it for 8 bits of data and one smaller hole for syncing I assume.
