One easy and fun way to learn is to build up a new light from off the shelf parts. If you look at the Convoy M1 host description on the Mountain Electronics website everything you'll need is pretty clearly spelled out. Try it- it's really satisfying to take a pile of parts and turn it into a fully functional and truly useful custom light.
Welcome to BLF.
Here are the pics of the OP light
Also found this pic online of the light kinda apart. I will say because of that spring on the back, its design may not be something to mod as a higher power 5 emitter build. It will be lacking in heat sinking ability.
I do have some Chinese, yes. I have a Wouxun dual band handheld. It was a nice radio while it worked - it went deaf though. I also have a Connect Systems CS750 (DMR), a Tytera MD-380 (also DMR) and a BK Radio KNG2-P400 (P25). If you have any DMR repeaters in your area the Connect Systems and the Tytera are decent radios that I personally enjoy using. I will prob never buy another Wouxun unless they come out with a new model that proves to be better than what they are making today. I have friends who have Baofeng and they seem to be well worth what they sell for, but are generally considered as “throw away” units. I also have an icom IC-7000 for my base HF rig. Looking to upgrade it soon to one of a couple software definded radios (SDR).
In reference to flashlights, I really think I want to buy something and mod it to start. And thanks for the tips on my broken light. I will take it down and see if I can see any issues. If not maybe I will ask for input on how to rebuild it bigger and better.
Are you sure you want a FET DD driver?
Hmmm… maybe you do for that 5 emitter light, because that could handle a LOT of power before it costs a lot of efficiency or LED death, that is, when you have the thermal path from Led board to flashlight body sorted out.
DD (direct drive) has no CC (constant current) regulation so there’s no current limiting done.
It would be better to have current limiting on each mode (no PWM)
Neven (member led4power) has a nice FET CC driver.
You could use the 12 Amperes version, which can be limited to 7 Amperes with a couple of clicks.
And then you can optimize the electrical path without risking LED death.
It comes with an NTC (super tiny SMD NTCs, a bit of a challenge maybe…) for thermal regulation (reducing the current when it gets hot).
DD may give you the highest output ‘the easy way’ perhaps, but only when the battery is fully charged.
Anyway, i’m not a fan of the DD concept.
“Better” in which way?
A Direct-Driver gives you the most “wow”-Factor and you also have some modes on the driver, so you mustn’t use the full power.
Also the tiny light will get hot after a few seconds
