Anyone here like lasers? I’d like to build a laser but don’t know where to start. Any suggestions? I’m aware that lasers are _extremely_ dangerous and can cause severe eye damage if it doesn’t blind you first. I will be careful. ---

I used to have a full sand table with all the goodies, Try Edmund scientific or the other guys. The other guys have really high wattage and can be quite dangerous. The name escapes me but you’ll know then when you find them. The other guys also sell Tesla coils in many different sizes. Always wear your protective eyewear even if you think the device is powered down. Have fun. ---

Is Edmund scientific like a website or something? I took apart a small laser pointer I got from the Dollar Store… I wonder what I can do with it. ---

I have a powerful green laser I use for astronomy purposes. It literally creates a beam of light that I can point at the night sky and the beam appears to be pointing at the star, planet, etc. it feels like your holding a light saber if smoke or fog crosses the lasers beam! I’d recommend buying one of those and dismantling it to see what’s going on. They aren’t too expensive.

That’s the laser. Laser diode. :wink: People used to pull them from the DLP projectors for cheap. Others have gotten them from old disk drives and playstations etc. Not very strong, but lasers! You may need a lens to focus them properly. > [@PCaliyoyos](#): > > Have you built one? Nope. I was going to build one years ago. If you can solder, it’s easy with a kit. I decided not to build one after seeing the ease at which people were blinded at burning power (1kw & up). But burning stuff was the main draw to me so you need powa! Yet, when you accidentally reflect one off your fridge door handle and it hits a shiny sink part and blinds you in one eye from getting around the side of your safety glasses for a split second, I decided the risk/reward ratio wasn’t worth it. In a controlled environment that shouldn’t be an issue, burning balloons and the like. ---
