Regular8 (cable release) Timelapse Intervalometer

[S8 Booster]

those old graupners were really powerful if you could get hold of those. they were made to pulse you know.

probably difficult but possibly ebay.de

adding a little additional programable box will do if you want it - later?

It looks a very complex design indeed!
Maybe this is because I know nothing about electronics and have never assembled anything electrical in my life. (I was forced to knit instead).

So where can I find out info about ultra basic electronics, eg what is an ohm, what's a watt, what's electricity, what's a circuit) so that one day I'll be able to build one of these amazing things?

thanks

nice design, I have those same servos from my airplane radio.

sparky, I noticed you uploaded the video clips to the small gauge picture page instead of the ftp site, I did'nt even know that was possible.
I guess it doesn't restrict .mpg from being uploaded??

What about a cheap solution for electronic (contact) triggered cameras. I've seen one before, but now I can't seem to Google it.

I have a "Spondon Film Services - T1 Intervalator" electronic intervalator which gives a range of 0.3 to 95 seconds per shutter release. The copyright on the circuit board says 1982 and the design is somewhat primitive. It's a good reliable unit that;ll happliy run for days with its beefy 9V PP3 battery.

I was considering sripping it down and sketching out the circuit as it isnt too complex and can easily be reproduced (with exception of the circuit board). Whilst Spondon still has a website does anyone know if they are still active - this circuit would ideally be in the public domain but clearly I wouldnt want to compromise copyright.

If you look at the schematic, you could use a single 555 timer configured the same as the (b) half of the 556 (lower right chip) as an intervalometer for electronic release cameras. It would last forever and could be run off the cameras power, or with the relay or a transistor output, using a PP3 (I think- will have to check the rated voltage of the 555)

If you know nothing about electronics of course it looks complicated, but it really isn't. Its a matter of joining the dots as it were with solder. I would suggest a good place to start with learning more is a kit from Maplins (Radioshack)- get a cheap one, a cheap soldering iron and have a go- doesn't matter if you get it wrong, but when you get it right you'll feel very chuffed! For that matter why not try this? If you print out the schematic (I'll do a version just for electronic release later) take it to your local electronic store and have them kit you up. Join up the connections, add a battery and see what happens! Getting to grips with the basics is at your fingertips- google for "understanding ohms" etc and you'll find the best basic electronics info.
Good luck!

PS- I didn't design that circuit- I got the servo controller bit off someones web page I found by googling as that was easier than working out the values myself (though I could have worked them out) The intervalometer bit I designed from the chip data sheet ;-)

OT:

Excuse me, Sparky, what is exact name of the camera You have in avatar? Is it Regular 8?

Greetz!

[Sparky]

The model name is Leicina 8S, and yes they are R8. Its the same cam in the mpgs, but with the front off.
