I found this posted by Bruce, kind of answers my last question:

Make sure you're using a separate power supply for your servo, and you have a common ground between them. Running a servo from your controller power supply can cause problems if you aren't using a hefty bench type power supply with a lot of filtering to remove motor noise.

Yup, as always Bruce gives good advice.

If the servor is a small one like the ones from the basic stamp folks you can get away with one battery pack and a large capacitor. At least they sell their little robots that way and they do work pretty well.

PROJECT UPDATE:

PIR was a snip. Works fine off a 12V battery and has a pair of N/C contacts for 5V onto the PIC.

I've managed to mount the servo into a housing and 'rig_up' a bracket to hold the cable release in position for the servo, looks good and should work a treat.

All I need to do now is finish the program. I'm off all this week but Mrs LEDave has had me replacing the garden fence No sense of priority some people!!!

I'll post my program up asap.

And if the badger is on the outside you may not need this project???

Lol....

Wooden panels down the sides, wire and post at the bottom, we back onto an open field (Badger friendly fencing!).

That said, they come in from the front, down the side of the building and into the back garden (we think), talk about nerve.

The project will prove once and for all what's going on in the wee hours.

Fence update: I should have got a man in..... No, I should have got two men in!

Hopefully tomorrow I'll have a bit of time to set too with the program.

Hi mackrackit,

Still struggling for time at the moment. Will get back onto the servo as soon as I can.
