To me for a budget head lamp, not much better than the Boruit style single or dual LED headlamps to mod. I modded a dual, use it like every day on the bench. Quadrupel has a custom driver PCB for it now.
The Boruits make decent hosts if you donāt mind the custom-shaped driver. I did an MCU swap on mine and left the original driver board. I think I must have passed it along to someone else, I donāt have it anymore.
If $20 doesnāt break the bank, the Convoy H1 makes a nice host. Standard 20mm (?) driver board, e-switch with indictor on a separate board, LED on a replaceable 16mm MCPCB, no charging circuit to mess with, and the usual nice Convoy quality. I just sold mine to a buddy so Iām ordering a new one today. My first one just had an MCU swap. The driver is a decent 3 amp linear driver, but I might take this opportunity to do a whole new driver, weāll see how well this new prototype works out.
Did you flash Anduril to the MTN-20DDM? Or did you have to replace the attiny on it altogether?
Iām still unsure of the best way to remove/replace/alter tiny components on the driver. I have a KSGER T12, an electric skillet and very little skill.
Iāve destroyed two MTN-17DDM drivers this week trying to install 20AWG wire and then find the excess solder causing high-only behavior. :person_facepalming:
Forgot what I did, but I see I wired in a ATtiny85, so chargin should be preserved. Thought it might have been a cheap direct wired up charger though, not sure:
charger board is separate ,just driver swap. Ordered boost driver PCBs it should be so fā¦. cool ;))
Convoy have 21mm driver it can be replaced with this one ;))
Dang, Convoy may be bout the only headlamp/rt. angle head EDC I don't have... I bought like 3 of the Eagle Eye ones when they were so cheap, offered in colors, and with 18650 adapters. I got a blue, black, and silver and only spent the time to mod one :FACEPALM:
Ohh no, I don't use MTN drivers. I reflow my own from OSHPark driver PCB's, usually DEL's but many others as well. I got a hot air system - works great to remove components, either all or singles, even small in tight spots. Forgot what it cost but I got it probably from eBay, pretty cheap, nothing fancy. You can get those all-in-ones with soldering iron and hot air, etc., but I have a good Haiko iron - wouldn't give it up for anything.
