Hey guys, recently I've been getting into quad copters and have been wanting to put an led light system on mine so I can fly at night. This is how it would work: I ordered some reciever controlled switches that plug into a spare channel on the reciever and I can then control them...

Hi guys, im looking to buy a M140 diode from DTR and i want to find a driver and host for it. I will probably buy it already pressed into a module with a Three Element Glass Lens (the $60 option from DTR). the host i would like to use is this: Aluminum Alloy Flashlight Housing Casing for...

I made a simple ddl driver out of a diode (for revers voltage protection), a 16v 47uf capaciterfor voltage spikes),and a resistor(for current setting). I am going to use a loc diode and i want to run it 400ma. what value of resistor should I use? Will it work without a lm317?

Hi, I have a phr laser that I recently made and it works great but when i try to focus it on a wall 10ft away I can only get it to about 1 inch diameter. is this normal? or is it just the glare? even the beam is around 1in. diameter. Can someone help:anyone:

I was just wondering if there is a more powerful red laser than the lpc815?

Ok, i have finally finished my lpc815 build:D and was wondering what a good next build would be:thinking:. maybe something more powerful:drool:? any sugestions? and I need a good host for my lpc815 any thoughts on that? thanks! :EDIT: What do you guys think about this host for my red?

Hi, I recently purchased some 650nm safety goggles from zonestealth. I have a lpc815 diode that went LED:cryyy: and I'm ordering another one, but when i look at the blown diode through the safety goggles it looks the same as without.:yabbmad: so i hope that when i get the new diode the glasses...

Hi, I have a loc 815 diode with a DDL driver and I have some questions. When i was measuring the curent the diode burnt out. I think it is because i hooked up the power first and forgot to short out the capacitor:yabbem: . I cant think of any other reason. so im getting another diode and will be...

hi, Im new to this forum and i need a little help. Im building a laser and I have an axiz module and i built this driver:- YouTube - DIY: How to build a laser diode driver-. what voltage should i run this driver at? and what voltage should the diode itself get? I've burnt out like 3 diodes...
