Crazy eBay green laser pointer mod. 1mW to 1400mW++

What started as a simple desire for a brighter laser pointer got carried away and I ended up building the brightest laser pointer in the world. social media sillyness: instagram: https://www.instagram.com/styro.drake patreon: https://www.patreon.com/styropyro backup channel and b-side videos: https://www.youtube.com/channel/UCz-3epzOdIyu-aXdeUaVP1A discord: https://discord.gg/hVZMcWT I would love to give a big thank you to all my Patreon supporters. I would not continue to make videos if it weren’t for your generous support. I have yet to take a paid sponsorship and rely totally on donations and overlay ads to support these projects. I bought some green laser pointers on eBay recently and I have to say I was pretty disappointed with the lasers. Half of the laser pointers didn’t even turn on, and the ones that did work were very dim and covered in dents. I decided I should try opening them up and try to make them stronger. I started with the classic “pot mod” by cranking up the potentiometer on the driver. It made the laser brighter but it still couldn’t burn stuff. I scrapped the driver and hooked it directly to my variable PSU but that killed the laser almost immediately. I realized that I needed cutting edge laser technology in order to satisfy my extreme desires. I settled on using the Nichia NDG7475 laser diode as that is the brightest laser pointer out there that is still small enough to be jammed into a laser pointer housing. I hooked it up to a high efficiency buck converter for current regulation. I used a MOSFET as the main switching component as the stock switch in the laser pointer would not have handled the high current demands on the laser diode. I also used high drain 10440 li-ion batteries as the thought of 2 AAA batteries powering this new circuit is laughable. The modded laser pointer is awesome. In fact it is probably the brightest laser pointer in the entire world if your definition of a laser pointer is a laser that fits in a 2x AAA host. I test out its burning capabilities by pointing the laser at a bunch of stuff. Sometimes I don’t even know why I build crazy stuff like this. Song towards end of vid: town of 24 bars - Unicorn Heads
