j45on:
Thanks Andy

Thought they looked the same and that confirms it  :thumbup:
I just hope the s-video lead has four core cable and not a pair of tiny coax cables.

j45on:
I got my 99p s-video cable today and it is a perfect fit and has four separate wires but it is very thick and inflexible so I think I will have to buy some plugs and make my own.  :zap:

I am also struggling to find out what capacitor/s to solder into the scale in place of the battery does anybody know ?

tumutbound:
The value of the capacitor(s) is not critical.
According to the Shumatech site, anything up to 330uF electrolytic with a .01uF ceramic in parallel.

I used a 100uF as it was the largest I could get in an SMD package.

j45on:
Cheers Tumutbound  :beer:
Kenneth  :thumbup: if I wanted to build a cable from scratch what would you recommend ?

I added some green filter today I was not happy with the colour it was a bit yellow under my shop lights
I'm happy now but I had to buy a roll just to get the bit I needed  :palm:
So I have some spare if anybody needs a bit for their dro  :thumbup:

Not that I want to discourage you, but in MEW issue 111 (Dec 05/Jan 06) there's Part 1 of a series about using chinese calipers and the Shumatech 350 readout.

The author said: "I found my 4 pin DIN plugs and sockets on the back of the DRO a nightmare to solder up. [They] just have solid pins to solder to. A type with solder buckets would have been easier with less possibility of solder bridges."

Good luck!
