Hello, i just wanted to share this story :) The first lm317t driver i built was just for testing a lm317t so i built that one as fast as i could. It worked good with testload etc. then i built serveral more drivers, which i put some time into. Well i recived a 300mW ir laser today i took the...

The flashlight only draws 3Amp, can i build a new driver using the bigger model of the LM317 (is it LM358?) and get the Cree T6 Led to light at their full potential? It looks like the Cree T6 Can handle 3A each and now they are running @ about 0.33A each. -Victor

Hello, How powerfull co2 laser do i need to engrave clear glass? Are the CO2 lasers from eBay any good? Already got the cooling system so if i got this right i only need a co2 laser tube and a psu to drive it? And glasses ofc :) -Victor

So i recived my m140 diode last friday and my sister thought it was a ring in bubblewrapper so she threw it across my room in to the wall (about 5m away). I tried out the laser later but it didnt work, optics look fine same with housing etc. Is there anyway to fix the laser? Otherwise im...

Hello, I just wanted to check that i got the right components and if i gain anything from using a different capacitor. LM317T 1 Ohm 2 watt resistor Potentiometer 2,2 Ohm 3w 47µF Capacitor Do i need a diode if im going to permenetly hook it up to a Relay supplyed with 5V? Is 5V enough? I...

Hello, Is this a focusable laser? 12VDC 200mW Blue Violet Blu Ray 405nm Laser Diode Module w TTL Industrial | eBay And this is odd, this one is 15$ more. Industrial 12V 200mW Blue Violet Blu Ray 405nm Laser Diode Module w TTL | eBay

Hello, Im thinking about buying a higher powered laser than my current ones, 405nm 50mW and 532nm 50-80mW. Ive looked at this one from ebay: 445nm 450nm 500mW Blue Laser Module TTL Modulation | eBay But ive also looked at this one: 1W 1 5W 445nm A140 Blue Laser Diode in Copper Module w Leads...
