add resistors for LED, not included in schematic (and neither in my protoboard) and a transistor for more IR range, measured 387 microampere in the main loop while in sleep and 8mA while triggering, can it be made to consume even less in case the switch is left on?

Current version instructions:
to enable timelapse function press pushbutton while powering ON the remote, the red led will flash each second passed, once you release the pushbutton this will be the interval time.
to exit the timelapse mode, just press the pushbutton longer than the intervall, once out of the mode the red led will flash briefly.
After exiting timelapse mode, if you press the pushbutton momentarily it will trigger once, if you keep it pressed it will trigger continuously.
if you start the remote without the pushbutton pressed it will work like previous paragraph.
While I was driving home I had an idea, why not add 2 more pushbuttons to easily have longer periods, one can be x10 seconds and the other minutes. And then, when outside the timelapse function these buttons can be programmed to trigger a certain amount of photos in a row, say for example 3 photos and 6 photos or any combination that can be programmed.

Nifty project. Could even use a serial LCD and have a boat-load of options with a menu.

Hi,
Speaking of intervalometers, did you see the one at http://www.doc-diy.net/photo/hdr-jack/#thecircuit ?
It uses an atmel and is meant for a Canon, but the design is ingenious.
Or this: http://cms.diodenring.de/en/electron...tervalltimerv2 ; based on 10F222, works with Canon, Nikon & the newer Pentaxs.
Planning to build one for my Canon 500D...
Regards,
Anand

I started with a Canon A570is and CHDK but wanted to use the DSLR for its many advantages, built the diodenring timelapse but my brand new pentax K-x does not have the 2.5mm jack as my previous pentax K-100, stupid me I realized this AFTER building itOriginally Posted by ardhuru
Regarding the HDR-jack I think this can also be implemented via IR, but not looked into it yet.
Regarding the program in this thread, I know the timing loop at the begining can be improved using a better way to count time. I could use some help there

Darrel has some great interrupt include files. It makes it pretty easy to do some great things with interrupts, and they can be very efficient as well. Here is a link to a timer example of his. http://darreltaylor.com/DT_INTS-14/elapsed.htmlRegarding the program in this thread, I know the timing loop at the begining can be improved using a better way to count time.

interesting, never looked deeply into them, now that I did I have some warnings at compile time, maybe you can help me
PIC12F683
pbp 2.60b
latest mapsm from MPLAB IDE v8.63
Downloaded ReEnterPBP.bas and DT_INTS-14.bas from Darrel Site and placed at pbpw folder
And Im trying the example you linked (http://darreltaylor.com/DT_INTS-14/elapsed.html)
this example requires Elapsed_INT.bas which I found in this thread: http://www.picbasic.co.uk/forum/show...7473#post17473 also placed it at pbpw folder. Is this the current version?
when I compile the example (using MPASM from microcodestudio) I get these errors:
Warning[219] C:\progra~1\picbas~1\pbppic14.lib 2934 : Invalid RAM location specified.
Warning[219] C:\progra~1\picbas~1\pbppic14.lib 2939 : Invalid RAM location specified.
Warning[219] C:\progra~1\picbas~1\pbppic14.lib 3059 : Invalid RAM location specified.
Warning[219] C:\progra~1\picbas~1\pbppic14.lib 3075 : Invalid RAM location specified.
What Im doing wrong?
