CT Lasers 21W RGB

[flecom]

I know I wouldn’t want a projector without a window, for that matter I won’t settle for less than hermetically sealed projectors with heat exchange systems anymore. Ever since I did a beach party (indoors) with conventional projectors, where afterwards I had to disassemble all projectors to clean them, even though all systems had filters on the ventilation, it was incredible. Nothing like getting the inners of your projector sandblasted.

thats a bit extreme...I would rather not have to carry around water and a heat exchanger when my projector already weighs a ton

No water, 150-300W (depending on nummber of TEC's used) 4 channel MCU/PWM controlled TEC heat exchanger direct on the Projector. Has a 200mm x 100mm foot print on the back of the projector with 2 100mm forced air fans inside and out.
I'll post some pictures when im done with my current build.

Darcean is looking forward to his projector and that's what started this thread. Poor Marc.

Fair enough. I guess we did derail the thread a bit. Let's blame Andy! LOL

...Poor Marc...

Nooooo, no, no; there is no poor Marc. Marc got paid to build a 21 watt laser projector... and he gets paid to go out and play with lasers... so, there is no poor Marc. AND he plays with piles of fireworks every year for fun.

Hahaha I have no problem with the thread derailment, its quite an intriguing conversation.

LOL - Come to think of it... I DO have a lot less money than I used to and, it seems to be in Connecticut.

LOL LOL...

You should have seen the fireworks THIS year!!! lol...

TRUSSSSST me....There is NOT as much profit in building projectors as one may think!!

Aaron- don't hate! You work for PANGOLIN! thats damn cool!!!



And yeah, thread derailment is ok. Very good convo and questions here.

I know right? I seem to have the same thing happening to me.. hmmm XD

I believe Kvant now do a case option thats sealed to IP 67.

According to the Wiki that requires a test of 30 minutes under water at a depth of 1m (3 feet 3⅜ inches for the imperial parts of the world) !!!

I reckon that's pretty sealed as sealed goes! I'm also not aware its water cooled unless of course it is submerged.

However, I take your point. Sealing a case entirely does throw up all sorts of cooling challenges albeit I think looking at the Kvants, it obviously is something that can be overcome.

What you free-spirited, libertarian Europeans fail to recognize is this not an issue impacting people who manufacture laser projectors and those that use them. This is an issue that affects EVERY SINGLE THING WE DO. That chewing gum is regulated. The power inlet socket is regulated not to mention the nuclear power plant AND the tooth paste. I think if I was in Marc's position I would simply go postal (funny how government affects some people) and get out of the business. It's kinda gratifying that the aperture is left open (stupid) for compliance only and everybody knows it.
