Love me some ryobi stuff!! Looking Iwould just use 1865os if youhave some good ones. Liposxwill do too

You sound like a parts hoarder like me. lol! Im bad!!! I'm sure you already know this but you can buy a TECs dirt cheap on Amazon or eBay. This is just the ceramic junction itself, no driver, heatsink and or fan. Years ago I bought a dozen just to play with, cost was like $30. They worked for...

Extremely impressed with this diode. Started using the DTR 2 element lens vs an older(almost 10yr old) two element and wow is all I can say. Still experimenting with DIY beam expanders but may just order the sanwa BX just for ease of integration. Honestly though I'm probably just being anal...

OK, It appears I was wrong, a lens IS needed before the projector lens assembly. Was able to do some "mid-field" testing this afternoon, about 500' was my line of sight limit. For a proper far-field test I need to get to a wide-open area preferably somewhere with a good flat target such as...

Thank you! Yes, a decanned 525nm😨 so Im trying my best to keep it clean. Been there, done that lol! I was also worried that a focused output into the BE would damage the optical coating but maybe Im just crazy, IDK....

Yes, but this is the lens after the messy liquid. Lol. Its rear projection not the ones that were projected onto a screen. Learned about the glycol that the hard way, I removed the pictured lens and noticed colored one beneath it. I kept removing screws since it looked like a big solid lens...

Trying not to open a new thread as I want to stay on everyone's good side here. Im doing the same using a projector lens as a beam expander. Budget engineering and using what I have. Question is should I first use a 9mm barrel lens before sending it into the BE. I seem to get better...

OK, I removed the boost drive. Never powered it up I swear, seriously... Soldered new 24G silicone leads on diode. Soldered those leads to DIY #14 silicone w/ 4mm bullet connectors to a variable current/voltage power supply. All precautions are taken to avoid a surge when connecting. No...

Wow! That probably was the spark that ignited your life long interest. Not too long after its invention either. That's when they were a solution looking for a problem. Lol!! Bet it was impossible to imagine how ubiquitous and essential to daily life they are nowadays.

Damn, mid 70's... Lasers probably werent even much into the publics consciousness. Had to be a shock to see those collimated beams of blue and green. The CU vapor laser PF used in 94 was previously used for uranium isotope separation. Not sure of the power but I remember watching the beams...

Dont think its a worry

Usually shows up like this. https://images.app.goo.gl/6z1xoYa6M1MfaSfX8 To me it looks more like a reflection in the lens housing.

Good job! This kickstarted my laser fascination into high gear..Pink Floyd copper vapor laser 1994. Blew my 20yr old mind, still blows my 45yr old mine!

No insult taken Paul.. Ive read enough around here to figure you are well-meaning. Ive said it before, the current set of regulars here are helpful and much better than the troll hole this place was in the past. How a laser pointer forum became such a place is a riddle wrapped in a mystery...

My eyes suck. Didnt see the . Thanks, issue resolved.

I think you confused me for the op. I agree with everything you say and thought your post was great. The eyes 574 million pixel equivalent is amazing and something I can add to my bank of knowledge. There are ways we can exploit cam sensors to do things that our eyes cant but few are...

Great info! Not so much to do with lasers but I can think of one thing a camera can do better than us. Stare and collect photons during long exposure astrophotography shots. I'm amazed at how much my eyes are missing during 20-30sec exposures of the night sky with camera on a tripod. I love...

says 2W right in his post. Maybe we're looking at different posts.

Those clamp meters dont really have the resolution for measuring low currents. I have several high end flukes with AC/DC capabilities, even have a small one specifically made for smaller gauge wire. Wire angle needs to be perpendicular to the CT, wire needs centered, wide variance occurs even...

Damn right 2W of 532nm was a good deal back then!! Still a good deal. Lol! DIY DPSS aint easy. God, like 10 yrs ago I remember trying to realign a crystal assembly that broke loose from a 200mw (not verifiyed) 532nm focusable laser from DX. Extremely hard to align correctly, just the...
