This is very coolI am hoping to archive that. I did every „good practice“. The casing should hold the vacuum just fine. I did go to grate efforts to make every seal a metal/metal or metal/Glas seal. Everything should be very tight.
The diode is still in it’s can. There is only one Bar pressure difference, so no problems with the can window.
I will do experiments on longevity (keeping vacuum) and best diode. If I do have these Informations, I am thinking about a groupbuy for the 120k Tec. Price should be around 100€. Power usage would be around 80w. Maybe I could even offer CNC milled casings.
nice thing is: we could make this fully tunable from 613 to 640nm (heating and cooling).
I will keep all of you updated.
FIRST, I'm not knocking this. It is very well done and it screams awesome. Only thing I would be concerned with is total cost. By the time you buy the diode and the TEC and milled casings and pump and other bits, it could push the price toward where another option might be more cost effective or consistent.
I say this, because I've caught myself doing things like this and ending up spending more than if I went ahead with the original in the first place (even though I learned a lot)
Still interested though!
