Bulb exposure bracketing robot.
Will do exposures for 1m, 2m, 4m, 8m, 15m, 30m, 1h or 2h, as selected with the left "select" button and indicated by the LEDs. Includes automatic 1 or 2 stop bracketing if selected. Program starts when the right "START" button is pressed.
For the video, I have used a recompiled controller firmware where time passes 20 times faster. Hence, the leftmost 3 LED program results in 3s/6s/12s instead of 1m/2m/4m.
This looks to be a very cool setup for intervalometer/HDR use... I'd like to see the full schematic and parts list for this. I'm using CHDK for most of my time lapse sequences now, but I don't think CHDK is available for the DSLR models I am looking into, so, I will need some sort of triggering setup... Nice work on this! =)
