    Still waiting on some board-revisions and code from dnar.

    I did some updates on V2, added a external 20MHz clock so we can get a higher PWM frequency out of the ATmega168 (keeps down the filter real-estate) approximately 75kHz.

    Current build:

    1.) Added separate supply pin for the bridge, now allowing 12-55VDC (allows more power)
    2.) Added diode driver with precision analog modulation up to 300kHz, supply 8-24VDC/4A.
    3.) Doing a SMD version first, conventional build will follow.

    Cheers!

    SWEET! A TEC/Diode driver has been needed for quite some time! With no supply of fmods currently it would be a good time to get this into production after the bugs are worked out!

    If you need one of these testing / any assistance from an electronics engineer let me know. I've got a dual green DPSS puzzle here I need to sort tec & diode drivers for.

    I've just completed my own op-amp / Mosfet CC diode driver to 5A prototype for my blues & reds.

    Failing that put me down in the queue for a finished unit.

    Sorry, I have been dragging my feet. Work has been mental, add to that Mothers Day, laundry cabinet refit etc. and I have not had time to scratch myself.

    Ah yes. Well that is now sorted after locating a source of the "wrong" handles...

    I shall endeavor to wrap this project this weekend.

    Well I'm in for ditchin V1 due to the MCU not being able to output a PWM @ 100kHz requiring to much PCB realestate for filtering. The V2 with around 78kHz is better but still not quit optimal (=>100kHz would be best).

    Hey Wayne.. how's tricks dude. If you don't have time to finish the software, can you send me what you've got and I'll try to sort it out myself?
