Cheers Andy I shall keep that in mind  :thumbup:
I am having trouble with scales though,I have wired one up to test and it was working fine with a battery  but wont work without one :scratch:
I have a 100uF electrolytic with a .01uF ceramic in parallel as mentioned by Tumutbound

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."

I got rid of the DIN plugs and used 4 pin microphone plug/sockets similar to these.
Much easer to solder and as they screw together, no chance of scales becoming disconnected.

Gereat thread everyone. A lot of questions I had.. but hadnt formulated have been clarified, and answered.

An example.. why get the small digital chinese ones.. but now I understand much better how they work, and how the DROs work with them.
