    Was thinking about having jacks instead of hard wired cables, but a 4 pole 3.5mm panel mount doesn't seem to exist.
    I bought mine from maplin electronics www.maplin.co.uk P/N QT65V

    Great Job. I had wanted to do something similar to do time lapse recording on the HMC150, since it doesn't have that function natively. Just start/stop recording at set intervals. Totally possible now that you spelled it all out.

    thanks!

    Very impressive - would this work with an HPX171??

    Do you have plans to make this commercially avilable?

    I wasn't planning to. It is quite fiddly to make and it lacks the panache of the VariZoom range. I just felt like a challenge. I did the project and documented it in a day to share with others.

    You asked if it would work with other panasonic cameras. The answer is it looks like yes, some: - based on the compatibility chart that the Varizoom folks post for their controller.

    I guess it wouldn't be single frames - but a collection of frames between making two switch closures.

    Since making my remote control for the HMC 150, I sold my Zoom H4N recorder and bought the Marantz PMD661 audio recorder. This, to my ears, has a better recording sound (less harsh) from Rode NT1A/NT5 and NTG3 condenser mics than the zoom and less noise too.

    In the back of the Marantz manual is a remote control circuit for rec, rec/pause, play, ffw, rew and mark. It was easy to make up this circuit but the trick was to put in an extra parallel control for the HMC150 record function. I couldn't find any double gang momentary switches, so I put two next to each other, one for the audio, one for video. I wired the video one to a 3.5mm mono socket, so that I can optionally attach a secondary control cable from the HMC150 to my do it all box. For the HMC circuit, it just required a push switch, stereo 2.5mm plug, 3.5 mono plug and 3.5 mono chassis socket. I have the best of both worlds now!

    Mr. Woodhouse - excellent work! A quick question - if one had no need for the zoom and iris sections, could those simply be ignored and use the circuit without them? I would only need the focus and on/off.

    Thanks for your work on this!

    Sorry for the delay, to answer your question, yes, since the effect of each enable switch is to simply open circuit the resistance path.

    Your original link seems to have disappeared. Do you have a new one?

    Ah - I had someone hack my web space. I'm rebuilding it right now. Give it 24 hours and it should be back.
