Can't really find any simpler ICs than the one mentioned I'll probably go with 380ma and try to squeeze a 18650 in the AA host. It's just 4mm thicker, it should fit according to the picture. Everything is being shipped, so I wouldn't know :s As for the circuitry, it's a bit different from the...

Was actually looking for output around 350-450ma The chip seems pretty neat, no components, but I'll have to insulate the heatsink / module. The amc chip didn't appear in my local element14, so I would have to go for eBay :-[ yeah it's very cheap that is, if I choose this one is there any other...

The chip I'm going to use is LTC3490 Linear Technology - Product Page It features quite minimal components, and runs from a single Alkaline / Nimh cell. Goes up to 4v/350ma I think this is pretty good for a ML101U29 which is a LOC And the fact that it's a continuous negative driver appeals me...

Sandwiched between Thailand and Singapore is where I live : Malaysia :) I am 19 this year, currently taking A-levels. What do I say.... have lurked for quite a while, sampling all the eye candies offered here I guess the interest started (or more like rekindled) when my desktop died Oh look a...

Out of frustration I was poking around the driver with the multimeter. By some chance,i connected the circuit via bypassing the POT and it started lasing... I resoldered the circuit by removing the POT. It works fine now, hasn't dimmed yet. I did not try to measure the current going through...

Hello guys, from Southeast Asia, Malaysia This is my first post... sadly not in the welcome section but the repair section. I thought I would post after I finish my first build from a DVD burner. Gotta have something to show the club right? Anyway, I made the Lm317 circuit without the...
