I think the mic is broken on the Canon G7 I’ve been using.\u00a0 It’s super low volume.\u00a0 Anywho, after frying 500mA relays on the external flash, I got the remote flash trigger working through a 5 volt 1 amp relay.<\/p>\n
I was working on soldering relays to old point and shoots.\u00a0 I ruined the first camera, a 5-megapixel HP when I accidentally shorted the flash capacitor another circuit (while trying to discharge the capacitor so I wouldn’t get shocked anymore).\u00a0 The second camera, Tedb0t was nice enough to donate, wasn’t proving to be much more fruitful.\u00a0 I soldered wires to the 4 points of the shutter contacts on the circuit board but when trying to use the arduino power, it wouldn’t work.\u00a0 I de-soldered the wires assuming that my solder job was lacking, and in doing so, I cleaned off one of the solder points as well.\u00a0 Andy Miller told me I can find another area to solder to (using the continuity tester).<\/p>\n
My nerves started up after spending a great deal of time with no progress.\u00a0 I knew there was an instructable on using a graphing calculator to control a Canon Rebel XT for time-lapse.\u00a0 Steve Litt looked at me, “wait… if you know how to do it… get something working first, then play around later.”<\/p>\n
So that’s what I’ve been doing.\u00a0 Here are videos (despite the crap audio) of a relay controlling the shutter on the rebel and an external flash.\u00a0 When I get the 2.5 to 2.5mm TRS adapter from Radioshack tomorrow, I will have independent control of the auto-focus feature and the shutter.<\/p>\n
I am also contemplating two flashes.\u00a0 One regular flash and one with a user-modified color setting.<\/p>\n
