Anybody remember that? Fantastic group buy that was, and I still have all but one of the lasers I got through that. Still alive and well are: The 808nm 2W, 650nm 300mW multimode red, 52mW 520nm first generation green diode, 80mW 450nm blue. Also the blue pen laser, it still works but the...

Subject says it, does anyone have the link to this? The youtube account name was "Dick Head". It was a really funny video. It was posted here on LPF but I can't find it now. :confused:

I have a PL450 on a Flexdrive set to 300mA and I want to pot it down a bit because 300mA is really overdriving it a bit and I'd like to turn that down. Which way do I turn the pot? I assume I'm ok to adjust it with a diode in place, with the battery removed? My PL520 went LED the other day...

I noticed a co-worker had a cheapie DPSS green laser. We work in a factory and the air is a bit hazy so even with the bright lighting the beam was clearly visible. I thought, "cool! he has a laser!" and asked him about it. The conversation that followed made me want to take it straight off...

I'm still here, and I haven't forgotten about you. I just got a new job that pays actual, real money, so I hope to get back into the thick of things soon. Who is the current go-to host maker? Is DTR still around?

Good morning. I've just moved into an apartment and I think it would be a good idea to install boxes on the Powerstat 136B's, to cover up the terminals and associated wiring. This is also a good time to install proper power indicators and switches on the units as well. The main thing is...

Been out of the loop for a while, but as it happens my last job was cheating me out of overtime and there's been a class action and settlement. So, I'm going to be in the market for a new laser soon! Is Ehgemus still in business? I have one of his hosts and it's great, but I know he took a...

A few years back - quite a few years now - I bought a host from Ehgemus and installed a 638nm Osram diode into it. This laser has seen it all - hard drops onto concrete and brick. Sub-freezing temperatures from being left in the car all night. Searing summer heat from being left in the car...

Hey all, It's been a while but I'm still here and I still have 20-odd lasers on my desk that I like to have fun with. I'm happy to say I haven't lost any of them despite having them for years and years now. I have much better income now and it's way past time to expand and get back into...

300V meter Is that volt meter a direct-connect type, or does it need a current transformer? I'm honestly not sure. It's pretty clear when an ammeter needs a CT because it will say something like 200/5A on it, but I'm not sure about this meter. It looks like it should be direct-connect...

I live in the USA so my house's electric service is 240V split single phase. The main breaker on the service panel is 200A. But 200 amps at 240 volts is 48kVA. The pole pig feeding my house is 25kVA, and there are three other houses (4 houses total) connected to it. I assume this is fine...

I bought a Basler Electric B-1823 transformer on Ebay and it arrived Fed Ex over the weekend. Seems to be the heater transformer for large RF vacuum tubes. According to the seller, it came out of a 20kW Gates radio set. It's 1kVA, rated output is 6.3V and 168A. Input is 200V, should be ~5A...

So the month of May is shit for me. My birthday is on the 7th but the BMV pisses all over that by demanding I fork out 50 dollars for car plates. Happy birthday, you crooks. Then my PO box fee hits, there's the monthly car payment theft, and the much more annoying car pizzo theft, a.k.a...

If you've watched Aussie50 on Youtube much, you've probably seen his DIY power display panel. It has several analog meters on it: Volts 0 to 300, current 0 to 20A, and current 0 to 50A. I believe it also includes an on/off switch and emergency shutoff button as well. I want to build one but...

I've had this laser for a while now. IIRC I got it sometime in late 2014. It's my "everyday carry" laser and you can see that it has some dings and dents. I never got around to photographing it due to being in a crappy mood at the time but this laser has gone a long way towards improving my...

It looks like part of my avatar is being cut off due to the column being too narrow. Is this a bug, or should I resize my avatar? And if I should resize it, what is the suggested maximum size? Thanks!

I couldn't get a really good photo of this, but these are OK. I guess I need a good digital SLR but given my income and need to constantly scrimp on every bloody thing, good luck with that. I've been having problems with this propane torch. The flame isn't very stable, it surges a lot and a...

They are "Westinghouse" 3.7V 2000mAh. They're in the lawn and garden area near the solar LED lights. At my store they are $13.87 for a pack of 4. They probably don't hold a candle to Panasonic NCR18650B and I'm sure they're made in China like everything else Walmart sells. But at ~3.50...

Everybody knows that one of the legitimate uses of a laser is to point at stars. It works a lot better than trying to point with a finger, going "that star, no, that, that one, right there." People do that and obviously they have no malicious intent. I point at the sky at night. I'm not...

I removed a single-phase induction motor from the cistern pump that is in my basement. The cistern has been removed and the pump cylinder is stuck. AFAIK the unit was seldom used. At any rate, we almost never used the thing as long as we have lived here. The motor is a Packard Electric model...
