https://www.strawpoll.me/45219304 put it in your sig if you want. The result wont be valid as it is anonymous and can be cheated. But I find it funny for him to try to work at it.

I got request in PM to start this poll. This thread is not to be closed before the topic has been resolved, and it should preferably only be done by Avery. I also encourage Avery to be present in the conversation below.

Im not worried about this anymore, this clearly wont last.

No one here can even start thinking about dealing with you if you wont even explain your actions. And that was just in this thread where it was easily spotted. Who knows what else you're doing elsewhere?

You did not restore reactions. Why are you deleting stuff?

Agreed. This is concerning. I was more expecting him getting a ban for his behavior to others around here.

What is exploding exactly? Also I must ask if you know how to hook up the correct polarity.

Laser diodes become more conductive and pass more current as they heat up. If you were to perfectly fine tune the voltage until it draws the desired current at room temperature, the diode will soon after start drawing more current and get in thermal runaway situation. With current regulation...

While waiting of the diode I've working on a combined diode and TEC driver, as the absolute ratings of 20-30°c feels too risky for such a special and costly diode. I'm not experienced on how such a driver should be made so I just went my own way. It seems to be working OK, other than and the...

Any part of the circuit that's not ground is vulnerable to ESD, so yes it can happen again. Also switching the power on the ground side may not be the best idea. I would use a PNP or P-mosfet on +Vin at the 17Ohm resistor instead, but it's unclear if this was the reason of the failure.

Yes I've read this too, but it is a common technique still. I used the PWM example as he had questions about it before and why it is commonly used to vary power. A pot would never adjust a TEC without a meltdown, but a PWM controller would. It is nonsense anyway in the countext of this thread...

Most potentiometers can only dissipate 0.25mW. Expensive ones maybe 1W. It will melt, if not go up in flames if you try to control 400W with that. Maybe you remember what I told about PWM, this is one application where such is useful.

I'm not doing your homework of researching the solution that you claim to know. That's not how this works. YOU show US. Your talk of driving a 400W TEC with a potentiometer already screams how much you don't know your stuff. If you already have problems cooling a diode as it is, and with a 400W...

You're out before showing your solution you say is working? I let you have the satifaction of making me wrong. I just dont like you telling people to spend money on something without evidence.

We are not companies, we are are hobbyists. A company may not care how much money and energy is needed for an exotic solution, but asking that for a single member is not reasonable.
