TouchDRO Scratch Build

[Tomc938]

So I replaced a video driver chip on my Bausch and Lomb old school DRO but one axis still doesn’t work. After hearing good things about Touch DRO I’m exploring that route.

I’m reasonably competent at electronics. And looked at the kit form. Heard they used to be about $40-50. Now they list at $177!

So I’m looking at scratch built. Anyone by any chance have a circuit board design for the glass scales version based on the MSP430G2XX3 architecture? Just thought I would ask before I either breadboard it or design and print my own board.

Doesn’t Yuri post a build using the TI Launchpad development board?

Yes, but my understanding is that this is the “brain” of the controller, but you need to add:

I started looking at Yuri’s stuff ten years ago. As far as I know, all you need with the TI Launchpad is very simple level shifters.

Internet issue: There is so much information it is hard to find the relevant information at times. I looked at dozens of pages in Yuri's blog/website but never ran across this page.

Thank you for finding this! It gets me the information I need all in one convenient package. Moves things back to a level I feel comfortable functioning at.
