It's just a little 8-plant table top size for growing my common used herbs and such... It will have 9 leds total, 6red and 3 blue... I never thought of mains power, which yes I'm fine with.. I pondered using a step down transformer but figured id use the power packs I have. But if u could...

Hey ppl, so thanks to this place I built my first 425mw red laser and have since had much fun with it. My next project is going to be a 1w blu diode in a mag light... My current question is, can I build a couple LM317 drivers to power 3W red HP leds? I'm building a new hydroponic system and...

Hello, I was wondering if I run two 2.2Ohm resistors in parallel would that give me 4.4? Or would I have to run them in series?

Mybad, it was a focus issue...I got it burning. Although I think I should use 4-6ohm resistors cuz it's a bit underpowered.

I borrowed my friends meter...

n00b question...how do I tune it? I dont have a multimeter

Yea, 25ohm pot with 2x 10ohm resistors

Hello all! I'm new here and this is my first post. Anyway here are my specs, LPC815 diode running on a DDL driver with aixiz module. My resistors are 10ohm running @ 125ma. I'm powering it off 6v of AA'a. It is bright and the beam can be seen in the dark but no heat! I think my resistors are...
