Interesting, thanks. You've got a nicely equipped playroom there...

Hey, I have been asking around for some help but wasn’t able to get any when it comes to a project I’d like to work on. Maybe you would be able to help out..? I’d like to get raw data from a CD player, so just 0s and 1s not understandable data. So even if the CD disk has scratches on it, or if we stop the laser reader from moving; it will still give us whatever data it reads from the CD no matter how fast the CD is spinning.

Where is a good place to buy cheap but usable optics ?

I really enjoy your videos. They are very educational. I am just learning about lasers and I find your presentations to be very well done. I would love to apprentice you.

Great video. thanks Other than projecting stuff. What other applications can you use the lasers for? I am building a security system for my home.

[@TechIngredients]

Careful! For passive applications these can be useful. For active applications, I'm not going to encourage this.
