    Default Single channel GM20 driver with damping

    Hey guys,

    I have just finished a nice little GM20/other actuator driver. There is no reason why it cant be used for other driver uses, such as small motors and the like.

    Features:

    - trim pot for actuator excursion amount
    - trim pot for output offset
    - trim pot for damping - eliminate the GM20 bounce
    - Power supply up to +/- 30v making it suitable to run off the scanner power supply.
    - screw down quick disconnect plugs for power input and GM20 output
    - Max current output - ~500ma

    I guess a picture tells 1000 words.

    Cost for this board, $25AUD + shipping + GST if applicable

    Will have a 8 channel version of this design shortly that will plug straight into the DMX16T driver we have. Also a 8 channel DMX analogue board that will plug straight in is nearly finished Beam table time!!!

    Yeah, certainly a permanent offering. This single channel driver, along with a 8 channel version that the board is half designed for
