Oh, Okey... I get it now... but wouldn't be better to hav it for example at around 0 Celsius?

Don't think so in my opinion because I'm feeding the peltier with 1.2 amps and isn't near freeze cold.

Another quick question, could I use the DDL driver to control my peltier with about 8 amps of imputs? Wouldn't it burn the driver?

@MISTEREWILLING: As far as I know you can keep a constant temperature by having a constant current, that is using a LM-chipset family circuit, like the one from the lasers.

Hello, I have the following questions about a TEC Module (Peltier Module), hope you can help me with them: 1) I've read that this modules are current dependent, but I've also read they are somehow voltage dependent, which one is correct? If I want to get more temperature delta between the...

Minimum value: 440mA Maximum recommended value: 600mA This is according my experience based on the use of a TEC as temperature control and using only LG GSA - XXX diodes. Greetings

It's about 400mW, think might be necessary

I searched some info in the forum, hope did well, but couldn't find any appropriate information for my questions. Was wondering if I want to build a laser with the IR ( or near IR, whatever they are) diodes found on the 20x burning units: *How much power are they capable of outputting? *How...

Yeah I've collected a bunch of heatsinked-fan coolers from core 2 duo pcs that we'll be enough =D. But my initial question hasn't been exactly answered, what is more advisable, putting the housing directly over the peltier, or... mounting it inside a small heatsink; then laying the heatsink...

What you mean with "thermal runaway due to the increased efficiency at lower temperatures"? Also what else to be aware when lowering the temperature of the diode? Let's say to...-15 Celsius? -> 3 Farenheit Also: lower wavelength which results from the shortening of the laser cavity on the...

I meant pump, not bomb, my English is a little rusty.

Hi, just wondering: If I cool with a thermoelectric pump (TEC) my diode housing (Aixiz), what's the best way? Should I put it directly over the cooling surface, or mount the housing in a heatsink, then the heatsink over the cooling surface? Will the cold temperature reached by the peltier...

Quick-side related question, whats the difference of using a 1N4001 Diode against a 1N4004 or a 1N4007 for the dummy-load test?

The driver it's itself well constructed, even, I did two drivers: one on a protoboard, another with soldering. - @->chipdouglas: I think so, I touch some metallic stuff before touching it every time, like some paint less steel pliers or Aluminium foil. Is that the way to discharge yourself...

Please, make a complete sentence this lacks sense. Are you asking if I used a test load, or do I know what a test load is for, or some kind of measuring?

I'm using a DDL driver. I'm measuring the current at the diode, between the driver and the diode. Hope is enough info.

Hi. I'm in need of help, I've just wasted 6 22x diodes trying to do a laser pointer. 1) When I turn on the circuit (the capacitor is discharged, the diode was connected prior to the power source) it shines great, but then it dies, turns into a dim $1 laser. I'm measuring the current and it's...

Maybe its is that. Also checked modwerx.com and the prices in there are higher than mine, but thanks anyways.

Yes I did, between the diode and the driver. How bright, well... as if the pointer was low on battery, very dim... its damaged, can't see any other cause... The thing is I've ruined 3 of this 22x diodes... 4 with this one...

I'm not using any kind of battery just an adaptor that can output to 1.2A. Don't get what you mean with "How many ohms do you have on that output pin", I'm only measuring the current. I'm not using any kind of resistance, only my pot to control the current. I think the ESD could be the cause.
