TouchDRO on a mini lathe
Arbalist:
Yes, Phil's link is for the supplier I was looking at. I was only going to go for X and Y axis to start to keep the price down. When I meant slight premium I meant over the optical ones. As well as being much more rugged the magnetics I looked at were also smaller which is a bonus.
Edit: I've just looked at the prices on that site and they've gone up a lot since I last looked!
Maybe I'll wait until the Chinese start making the Magnetic ones ... :palm:

Ordered the MSP430 Launchpad from TI and developed a suitable PCB for the controller. The PCB was made as universal as possible allowing for any scale voltage and internal or external clocking on each channel, selectable by jumpers.

Hi Abraham,
You have made a very good, neat job of the PCB and housing case for it. I must admit it looks better than anything I could produce. One question, where did you hide the MSP430 ? I assume that the white module in the picture inside the case is the bluetooth one.
modeldozer:
Hi Baron.
It is the long IC close to the regulators, it is removed from the valueline development board in order to save space, and yes, the white module is the bluetooth one.

Hello Abraham,
Very clever :bow: I wouldn't have thought of doing that. It certainly makes for a very tidy layout in addition to keeping everything inside the housing where it is well protected. It should help with suppressing any electrical noise as well.
Electrical noise is one problem that I have with the single scale on the mill. It works fine for days and then when you need to rely on it the readout suddenly changes value or sometimes switches off completely. Of course when it is switched back on it has reset to zero. I keep meaning to get a properly screened cable for it. :doh:
Joules:
Baron,
wrap it in tin foil till you get round to fixing it, or strip a length of coax, bunch the braid slide it over you cable and stretch it back out. Good temporary fix The turkey fat will keep the foil on your cable :lol:
