  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

TouchDRO Scratch Build

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.
 
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.
