Timelaps Near Infrared

[aladaris]

¿How do you controll the shutter with Arduino?; i mean how must i connect both, camera and Arduino (not the software).

I've been searching info, but I'm quite lost :P

Nice TimeLapse BTW ;)

@aladaris Depends on your camera. With a cannon it's dead easy.. it's just a switch but with the DSCv3 which uses LANC control it's a headache. I bought a remote shutter release and simply wired the arduino directly to the shutter switch in that. So meter the 2 contacts on the switch. One will be ground one will be +v. connect them to a couple of arduino pins set to gnd and + and toggle one or the other - probably the + to activate the shutter.

Nice timelapse, I also have a V3 and I'm getting an arduino duemilanove, I know I won't have problems with the code, but certanly will have problems with the wiring, how you did it? btw, I could help you with code if you have any new plans with the v3. I'm good with code but not with wires :P

THe software is tricky as you have to commuinicate with the camera using the LANC protocol. I never managed to get it to work.

My work around was to buy some remote cable releases and simply hack the buttons. Couldn't be easier to wire. Just use a meter to establish if your buttons pull the connection high or low then tie an output pin to the connection and set it high or low when appropriate.

The 'smart' way to use a microcontroller to do this may be to impliment the lanc protocol on the chip and send commands direct to the camera. That's been done by some people but it's beyond my programming ability and frankly it smacks of effort :) My messy hack does the job.

Cool. Was it difficult to set up the arduino to do that?

[MarbleMad]

No. It was very easy. Just changed a couple of lines in the 'blink' demo programme and wired it to the hacked electronic remote controls I use on my stereo camera rig through a couple of resistors. It took minutes to do. I'm thinking of doing 3 short videos. how I do 3D, how I do infrared and how I do timelaps.

@MarbleMad Did you managed to make a video of 3D making and timelapse? I have a V3 but I just ordered a timer remote for timelapse.

excellent work! i loved the water shots... the wake in infrared was great!
