I got request in PM to start this poll. This thread is not to be closed before the topic has been resolved, and it should preferably only be done by Avery. I also encourage Avery to be present in the conversation below.

I'm tired of the political debates showing up as unread.

I'm in the process of making a portable white laser. I've already made a complete RGB version, but now I want to add 488nm cyan and 405 violet. Here is what I made so far: This is the plan to make RGB+CV: This schematic shows how the laser is made now. Some changes will have to...

Hi forum, I have dropped out of the hobby for a long while, but I recently got back into it. Now there are so many more direct diode colors, so I made this device to make it easy and fun to experiment. Just a large heatsink with a fan, and seven LM317 drivers with swappable resistors. The diodes...

I need a DC 24V power supply that can deliver at 5A. I first got one from Ebay, but it crapped out instantly. I knew it was a long shot.. Anyway, I got four identical 12V, 3.3A power bricks. They are double insulated, mains isolated (as far as I can tell) power bricks, similar to one for a...

Am I the only one here that is annoyed by it? How the prism refracts the light in the wrong direction, and also refract the beams by the same amount, despite their different wavelengths? I find it very distracting and unprofessional looking. Edit: I don't have any ill meaning toward whoever...

This is my first review, I will keep it short. 400mW blu-ray 405nm laser torch /adjustable/waterproof [OL-405T-400] - $102.99 : Welcome to O-Like.com, Your source for laser products The laser arrived after a few weeks after ordering a padded bag. The laser came in a cradboard case. It came...

O-like is out of stock. Or I'm interested in a 9mm 808nm ~1W pump like this one: So if anyone has one or knows a good source please let me know. I don't want to spend much over than $100. I'm happy if it can deliver at least 120mW and start instantly.

I just stumbled across this map-pack on youtube, if you have the pc version of portal you gotta try this! It's lots of lasers and optics, like a gigantic laser lab. It's very fun but I have to say the puzzles are tricky, but you just have to stop and THINK, then the solution becomes so obvious...

I accidentally shorted out my driver and killed the pump in my 150mW o-like module... I'm, looking for a replacement if anyone has one or know where to get one..? Here is a picture of the diode: I think it is around 1W. I feel very bad about losing this module, it was a good one for ones and...

I've been watching my balance in paypal account and found out that somewhere between Juli 4th and Juli 16th 444sek (~60usd) mysteriously disappeared?? I haven't spent anything so that is why I found this strange and worrying. It doesn't even show up in the history. Any ideas how or why this happed?

I got my 445nm diodes and LED from Pontiacg5 today (thanks! :beer:) and fired it up. It is awesome! NMZ0DxVEdhI The setup with a huge heatsink and fan: The LED: The resistor (copper wire). The power is from a ATX psu, 8.1A @ 5V. Optics:

Some of you might remember my LED Ball I made a few years ago... It had three LEDs and two axes. Now I've made another one with three axes! sO2-tqoyGik YouTube - Spinning RGB LED Ball II It was very hard to build! I has a lot of problems with the power transfer and failed may times before I...

Here's video I made about constant current and constant voltage and why constant current is superior in use with laser diodes. Watch in full screen. YouTube - Constant Current vs. Constant Voltage in use with Laser Diodes Please discuss.

So, Aluminium enclosure, White Fusion kit and Full Colour Driver... Awesome! fvUS8Axg_Fk Pics: I temporary added a pen eraser on a pin to the dichro, this made it so much easier when aligning the beams. I don't have a battery yet, but after allot of effort my dummy battery fits! The...

I have 100 super bright white blinking LEDs for sale that I bought some time ago. I'm selling them because they are not what I expected. They were described as flashing, but they are in fact blinking. What's the difference? A flashing LED makes a short pulse of light, like a photo flash and then...

I've been trying to find an aluminium box for more than two days now for the white fusion kit + full colour driver. I just can't seem to find the size I want, I've been looking tru digi-key without any luck. Maybe I just suck at finding things.. The size I want is L =125mm W=65mm H=40mm (4.92 x...
