    GM20 quad drivers. Four channel drive cards for GM-20 actuators. Each channel has adjustments for gain and offset. Requires +/- 12-18VDC power supply. Can deliver up to 3.5A per channel. Supplied with 0.5A fuses. These are great for optical tables, safety shutters, color flags (like the color box above) and open loop XY scanning. Can also be used to drive motors or ledex rotary solenoids. Can be setup to pull GM-20 flag out for 0V signal and push flag in with 5V for fast, bounce free performance. If you are handy with a soldering iron and experienced assembling PC boards, you can save $$ by assembling the board yourself (you will need a DVM and oscilloscope for calibration). Measures 3.25"x5.25". Built and tested - $90ea. Kits with PC board, all components, heatsinks, layout diagram, and parts list. - $60ea. SOLD

    I see you've gotten around to re-listing. Since I missed you bringing the stuff to the US the last time, if I recall it was the Ledex solenoids and the machado gratings. I'll go back and double check since I know we went back and forth on the meter.

    Steve, I know this is an old post but those items you had for sale brought back some old memories.

    I sold my UTD meter a couple of years ago on Ebay.
    Still have a 35mm rotary optics mount made by my ol' planetarium buddy
    Plan to use some of my MM1 and MM2's on my just-for-fun LD build
    I loved those linear diffraction gratings you had

    What else do you still have?

    Hey Steve

    Never really on here anymore

    Is the Fibre and Colourbox (without the colours) assembly still available?

    If those MM-1 kinematics aren't gone by friday, I'll pick them up.
    Those who fail to grasp art are the ones who criticize it.
