    Update !

    Got tired of waiting for a reply from DHOM.

    I monitored all the signals and deduced the pin-outs by sticking the head module in the fridge for a while.

    I now have those details ...if anyone needs them... just PM me.

    With external supply to the TEC, I can now lase at max power as much as I like !

    Problem seems to be the power transistor that drives the Peltier !

    God alone knows how that managed to go kaput in transport ..... ! shit happens !

    Now all I have to find out is what the transistor is and decide whether to replace the bugger !

    So I have to determine what I want more .......
    "an intact warranty of dubious value" or a " fully operational laser"?

    Ahhhh ! ......."to be or not to be"

    Will update soon once I have decided !

    Cheers

    Great job! Pity they let you down with their communications, I was mostly thinking of using them next for a purchase, but I think I'll stick with Laserwave.

    Yeah, Bridge seems quite prepared to give out the info needed to determine whether it is worth shipping back to China or not if the shit hits the fan!

    see: :

    That kind of reaction is what I expected from Shawn, however he seems to have vanished in to thin air recently !

    This leaves DHOM kind of "voiceless" unless you speak Chinese!

    I recently bought a 500mW 532nm laser from him through ebay. He has responded to all of my questions very quickly.

    I had excellent communications with him during the buying phase...
    Unfortunately I cannot say the same once problems arose...
    Too bad.
    Hope you don't have any problems... They perform quite well when you get a good one..
    Me and Mr Catalanjo both had TEC related problems that if not corrected renders the units useless..
    Anyway.. good luck with you unit, hope you don't have the same fate as us.
    Cheers!
