¿ªÔÆÌåÓýHi Glenn, This is indeed a strange group.? To be told contribute or else we'll throw you out.? And then if you do you get told your contributions are invalid.? Very strange.? Or in my case because I mentioned my Electronic Lead Screw project was told to shut up because it was a commercial product.? Which it wasn't and is totally open source.? In fact I used the Shumatech Keypad approach for it.? I've even written a tutorial on how to make one. ? Anyway, I've had a working DRO-350 for the past 14 years or so.? The DRO-550 is assembled but in the box as I saw no need to upgrade.? ? I used the caliper type scales with it.? And probably the most important part using brass tube and epoxy I created battery shaped clones with tantalum and bypass capacitors inside.? Absolutely no problems other than the DIN connectors I used on the bottom of the box.? The first two photos are from 2007. ? The last one shows it mounted on an arm inserted into castings I made for something totally different. ? I just joined this group.? Very friendly bunch.? Not exactly email based but there seems to be a wide variety of people from all over the world. ? ? John Dammeyer ? "ELS!

I joined the group to see if it could generate some interest in me doing CNC and CAD. I am a retired ET with more than 36 years of electronics background. I put together an all manual machine shop when I retired 15 years ago. I purposely avoided anything to do with electronics as I am burned out on it. I even built the shumatech DRO350...what a shitshow that turned out to be. Poor design with lots of noise issues. Even down to getting the polarity wrong so you have to use batteries with the scales...Frustrations I don't need. So, I bought the DRO 550 as it was supposed to be excellent and a huge improvement...then people started using them and all the glitches started falling out. Fortunately I hadn't bought glass scales yet and all the parts are still in the box. |
