I am bringing you a dual tracking power supply, a 1980's vintage Hewlett Packard power supply.
One knob could do with replacement, and one of the meters has been pushed in, but these are cosmetic issues only. I have tested the unit and it is within spec.
I will also bring with me a very accurate 10V source if anyone is interested in checking their multimeter. The cal certificate says 10.0000041 VDC (0.4ppm error). It actually takes about 2 hours to settle to this value, but unless anyone has a 6 1/2 digit (or better) meter this won't be an issue.
Oh, I also have some very accurate resistors for checking resistance ranges.
And of course I have some small samples of what I've done on our laser cutter using my software.
I would really appreciate if you can point me to the design you use for the 3D printers you're building, and also to the UV curing plastic resin printer.
Dave describes me as being in "nerdvana" last night. He also enjoyed the visit and plans to take his grandson to the 3D printer event in March in Goshen -- please remind us of the name and date.
