    Also I developped a small TEC driver, it's the lil board on the top of the module. It's adjusted for 20°C +-1°C, and seems to works well, despite it's only an on/off circuit with constant current source.
    And maybe I should consider an external driver case, as all these boards take a lot of place...

    Ah and about the power, I obtain a nice 1.2 watt after all the optics, with 350mA per diode, I'm quite happy
    All I can say is WOW. Thanks for sharing, you have made me change plans as I now see this is a cool way to achieve my similar goal. All required parts now in and some on the way.

    Thanks.
