This was one of my first soldering irons, I've had it for years and it still works fine; never even had to change the tip. As far as I know, there is only one size of tip...
I got mine from here: ABRA Electronics :: Soldering :: Soldering Irons :: Quality Soldering Iron-30W
Daguin - I'm going to have to disagree with you; the driver was sold under the assumption that it's preset at 550mA. If it outputs anything more or less than 550mA, it is technically defective. Yes, the components should be checked before assembly but the equipment or technical expertise may not...
So, why do we need more than one mod? Simon has been doing a good enough job so far; a small/ temporary influx of stupid noobs/trolls doesn't quite justify commissioning another mod...
To be honest, Simon is one of the very few members who are extremely level-headed, unbiased and abstain from...
Did you explicitly ask for the current to be preset? Did you at least receive a reply/confirmation stating that the current has been preset?
If so, I don't see why Drlava wouldn't compensate you for the two diodes...
Jenner6989 - If you want people to take you seriously, here are a few "rules" to follow:
1) Search before asking a question.
2) Search before asking a question.
3) Search before asking a question.
4) Do not start 50 treads to ask 50 questions; one tread titled "I have a few questions" or...
Most "ebay 5mw lasers" actually output anywhere from 10-30mw; I had one that put out 42mw once. I would advise the OP the have it metered and turned down if necessary.
Your apologies are commendable but you still have not addressed the underlying problem; dishonesty. Both "incidents" are cases of dishonesty and deception; the circumstances under which they occurred are irrelevant. I understand that selling something at a loss can be painful but think about the...
Running a diode with a resistor to regulate current is risky; you diode will last anywhere from 1 year to one second. Also, you are relying on the internal resistance of the battery to regulate current, merely changing the battery could easily kill the diode. A simple LM317 (DDL) driver as...
As sincere as you sound, are you only sorry because you were caught? If your auction wasn't discovered would you still have removed it?
You were trying to make a buck at someone else's expense; you should be apologizing to the bidders, not us... As for the tread I "brought up", it goes to show...
Potatorage has been proven himself a dishonest individual in the past; I'm surprised people still deal with him...

Murudai - If I where you, I would ask for a refund if possible. I had a whole load of money tied up for 8 months for some alleged "repairs". I end up getting a completely different unit (And was told that it was "rebodied") that was just as underpowered as the previous unit. I asked for a...
Most CMOS and CCD sensors are extremely sensitive; you will probably saturate the detector if you shine a laser at it... Have you considered using a high OD filter of some sort?
I've looked a pictures of the two and the only visible difference is a flattened ridge on the knurling and the "tripod mount". Heck, I counted the number of ridges in the head and they both have the exact same number... Stickers are virtually identical, switch and sticker placements are the...
Whether it's FDA complaint or not is immaterial; if it is not FDA certified with a FDA accession number, it's illegal to import. I'm simply pointing out that they are not certified and that the sticker is misleading; if it is seized for whatever reason, don't count on getting it back...
Looks very much like a skylasers unit. IIRC, a lot of their underspec second rate crap units were sold off to various chinese sellers.
Secondly, It probably isn't FDA certified! Last I knew, Skylaser units do not have accession numbers; the FDA sticker is fake.
What kind of motors are they? Brushless, brushed, outrunners? If they are brushed, I highly recommend the vex victor motor controllers; we used them in our HS robotics team. A very rough way to approximate current draw is to weigh the motor; the rule of thumb is "15 amps per pound". Keep in mind...
