    The new H bridge showed up – same Results… I have them wired exactly like the pictures you Showed me..

    Would this controller work with the LEDwiz?

    If so how do you think it should be wired?

    there really is no reason the H-Bridge wouldnt work. How are you powering the shaker?

    as for the motor speed control you linked to, yes it would work i would assume you hook middle signal 0-5v to ledwiz wire you already have and others are power and motor diode still would be needed.

    i use seperate quality switching supply to power shaker so perhaps your using a ATX computer supply and that just never a good idea.. not sure what your using but im using one of these…

    …or perhaps its a grounding issue?

    Yes I am using a ATX computer supply but I have a power supply I will try…

    But that still doesn’t explain if I don’t use the H-bridge the shaker motor runs at full speed….

    Thanks for your help

    Possible difference in grounds from the ATX Power Supply vs your Led-Wiz?

    Can you put grounds together from different power supplies?

    Sorry to hi jack, but I just ordered a small chip led wiz. Am I going to be able to to solder the wire on the chip. I ordered with heat sinks, maybe I should have not.

    yes im sure thats the same ledwiz everyone uses. buy small chip you mean like picture below?

    chapter-15-11-ledwiz-cooling

    If so then yes fairly easy to do. I dont they sold old style for many years (big chip)

    After putting the grounds together the same results….

    Then the new power supply showed up same results

    Then I tried the DC Motor Speed Control but that works a little different than a H-bridge

    It turns out The signal 0 to 5 volt Is a positive voltage So what I did is use the H bridge to control the DC motor speed controller And That worked pretty good but that required 2 items to do one job…

    Then I thought I would try one of these and it turns out it’s working great.. — 4 Channel Optocoupler Isolation Module board

    https://www.ebay.com/itm/1-4-8-Channel-Optocoupler-Isolation-Module-Opto-isolator-H-L-Level-Module-Lot/372031557305?ssPageName=STRK%3AMEBIDX%3AIT&var=640949719466&_trksid=p2057872.m2749.l2649

    The wire that I soldered to the LEDwiz – what is that exactly doing?

    It’s obvious it’s bypassing something….

    If I use that wire To control The 4 Channel Optocoupler Isolation Module board the shaker motor runs at full speed as soon as you turn the power On…

    If I hook the board to the port Like you normally do it works fine…

    This is what the v2 looks like.  looks like the chips are pushed together. I don’t know. Maybe solder from the bottom?

    That’s a very old photo of a ledwiz and don’t think they have used socket chips like that for many many years.
