Remember, if in doubt, always consult an expert or your local hardware store – you do not want to get hurt while playing with lasers!Last update on 2020-08-13 / Affiliate links / Images from Amazon Product Advertising API. Reply
I had a similar issue and noticed the lens was scorched. You can get it out of an old cpu that is not working You can test for the red diode by hooking the diode up to a 3 volt battery pack. Burn Stuff!
We’re also going to recommend some tools for the process below.If you’re looking for a good regular laser to try this experiment, we recommend LUCHENG’s 3 color pack.The blue/violet light is the best to use since it has a shorter wavelength and higher energy than red or green. So I made one, and in this instructable, I will show you how to make one for less than ten bucks.
For the question you asked above, the grey text is default value for the entire circuit, while thre red and black text are intended for a different LASER diode.

I always wanted the 007 laser that will just slice through anything, while this instructable wont give you that but it will let you easily slice through the black trashbag or electrical tape that Dr. No has tied you up with. 3 years ago Reply
Easy,cheap and Focusable! They are all rated at 5mw although I do not have a meter to verify this.
First video shows the three lasers in this instructable and the second video is my older one that shows some fun you can have with it.
For the record, according to internet research I believe the popping noise you heard was water explosively boiling at the back of your eyeball.
For that matter, keeping the assembly intact would allow operating each of the diodes as desired. Other lasers have notches instead of holes in the plastic base. 1 year ago
All you need to be able to do it is a cheap 5mw laser from ebay and a small lens.Seeing this diagram might help you understand why a lens will seemingly increase the amount of power a laser puts out.
And I want to engrave wood, leather etc also I want to cut balsa wood ( soft wood about 3-4mm), foam for making aircraft models.I need some information about this issue. Reply

Step 1: Diode. 9 months ago 3 years ago Put in 4 AA batterys in the battery pack, and fire it up!
The Laser pointer power is measured in milliwatts, which is denoted with “mW” in laser pointer descriptions.
And what those red black and grey text means

You don’t want any charge happening when you’re working with it.Then, pry off the lens cap with pliers. See the document here for the LM317 spec's: http://www.onsemi.com/pub_link/Collateral/LM317-D.PDF

Making this burning laser will cost around $20, but is extremely easy. In the configuration shown it operates as a constant current source. A convenient slide on/off button on the barrel activates the torch. It can block out the different wavelengths of a laser with a higher mW.This method is the simpler of the two. No, it becomes a burning laser because all the power, say 5mW, focuses on one area. 3 years ago Reply
