Do you have a few rectifier diodes and 1 ohm resistor? Making a test load takes like 5 minutes of your time.

What you need to do is, basically, measure the voltage drop across tha 1 ohm resistor, to calculate the current. Since calculation requires dividing measured voltage with resistance, you're ending up with pretty basic readout of 1 mA = 1mV.

Highly advisable

I really don't have spare electronics around, I guess I'll have to buy them if is the only way to test it. But I've never done that, where I'll read the values?

OK, next visit to your electronics store, buy 10 diodes marked 1n4001, and two or three resistors value 1 ohm, and power of 5 W.

We'll move after that

Ok, got the stuff, diodes are 1n4007, the clerk said is the same, hope so...



How do I proceed?

It is the same, don't worry (there are diodes 1n4001 to 4007, difference is how much voltage can they take, 4007 being the highest rated).

You would need to connect 4 diodes and 1 resistor all in series. Take care of diode orientation.

Search for "test load" or "dummy load" here on forums for better explanation.

And also, try to take a little better pictures next time, at least let your camera focus, I get headache from looking into out-of-focus pictures.

Default Re: Stripping a benq dw1620

I've built a test load with VERY similar resistors. You just need to watch the rectifier diodes orientation. It is marked with a gray stripe where it is negative, and nothing where it is positive. Wire one diode positive with another diode negative and you'll be fine. I'd post my test load but I'm without a camera..

by the way.. what is your soldering iron power? It should be marked on its retail box something like 10W, 15W, 30W etc.. when it is on you can feel the heat ~10cm away? I'm skeptic about your laser diode with a big solder blob in his pins.

I've still to see it because it's not mine and I'm borrowing it, but yes, I'll really try not to burn my diode after all this work

Right! You got it. Not that many diodes, tho, for reds I use three..

You have a multimeter.. you show it up on another picture... it just need to suport milivolt scale (show as 1000m in some multimeter, or 1v etc.) with it you can measure safely.

About the number of diodes I was just following what Eudaimonium told me.

And the multimeter, yes, I thought it was ok but it doesn't seems to turn on, maybe something is broken...

Default Re: Stripping a benq dw1620

about your 2nd reply:
My recommendation if you do not know your soldering iron power..
turn it on and keep trying to melt solder/tin on him. When the tin melts (after the iron is hot enough) keep it on for 2 minutes more, and turn it off (from the socket or button, if yours have a button). Voilá! You have 2 minutes to solder with it. If you left it on too much time, it can heat the diode and immediatly damage it. I've done it 3 times before I figured it out when I wasn't @ LPF. lol

Ok then, I'll try with the minor heat possible but I think I'll be able to know the power
