Historic story since I haven't posted in a while and this occurred in 2015. I was using a 100mW 405nm to charge a section of an object 3D printed with glow-in-the-dark filament. Sounds fun, right? I had suitable eye protection available but I wasn't wearing it on this occasion "as it's only...

Another idiot in this video: https://www.youtube.com/watch?v=s-_uAC2dawI At that end, is that them finding the warm pointer in the grass?

I've watched the video, it certainly seems to produce a lot of steam. The inventor states he is not a scientist and doesn't necessarily understand all the science behind it, and the scientist that visited it stated that the measurements weren't strictly scientific and no conclusions could be...

Well that guy was lucky it was his arm and not his head. I think you've successfully made your point about the foolishness of others.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Indeed - I use a VFD to drive a three phase hydraulic pump from a single phase supply. Can chose the output voltage/frequency you want, it soft starts and has overcurrent protection - VFDs are clever bits of...

Not the brightest diode in the array is he?

Get a hobby charger* and check their capacity with a charge/discharge cycle. I've checked hundreds of salvaged 18650s, some are 600mAh, some are 2400mAh, personally I keep anything over 1800mAh and send the rest for recycling. *and some magnets to stick onto the terminals and grip with croc clips

I was thinking more along the lines of the wiki being hosted here too.

Why not make the wiki part of this site with an auth-bridge to the forum? That way only forum members can edit the wiki and share one login.

Don't know about you lot, but I now have a mental image of some guy in Maryland burning his tonsils trying to smoke it. ;)

There is no need to cycle them, and no harm in recharging after a partial discharge. Just avoid heat and deep discharge and they will be fine.

Good luck with that ;)

Correct me if I'm wrong but he's looking at a phone screen while pointing the laser into the camera via a reflection? While ridiculously stupid because of the proximity to his face, the risk is his outlook and any damage will be to his eyes alone. I'm all for people making their own judgement...

1mW or less probably fine for most people, 100mW+, old enough to make sensible decisions to mess with danger. I'm not convinced I'm old enough and I'm 38 ;)

It sounds very interesting from the website. They do state that the output is guaranteed, and that it's not like the others with false claims no output power.
