I haven’t started to mod flashlights yet.I am just starting to learn. When I am ready though I want to mod my Mateminco MT70 plus. I want to change the driver so I can either put in a sbt90.2 or sfh55. Is there a driver that will work? What all is involved. If anyone has a suggestion please let me know.
@ Jimo:
Convoy has a 30mm driver for the SBT90.2 rated at 21 Amps IIRC. 2S or 4 (2S2P) cells. However, the store is closed and I can’t get the link.
It should fit within the MT70+ (same body as the MT70, much larger head).
Some ‘inspiration’ for future generations.
I think I diced a little bit too close. It looks like some blue is leaking out. And I can probably remove more from the top.
Update:
Don’t want to spam too many photos, but just tested it and it’s much better already. Going to remove more from the top before posting the final result.
Update 2:
Went too far (0.7 mm). Enjoyable experiment though!
I want to thank everyone who's ever posted in this thread .
The modding community on BLF has always been just amazing and I'm inspired every time I come here.
I agree!
This thread is a great opportunity to share info, and to learn from others. It inspires me as well. And the people in this thread are a great support system, with extremely helpful people contributing.
these, and many more, are all modded thanks to support I receive here on BLF

I can only join in the praise. The amount of knowledge in here is fantastic (goes for the whole forum!). And it encourages to try new things. Even if it ends in utter failure, there’s always someone with some advise or tips to learn and improve.
What is that aux ring?? I really want one.
Yessss!

You madman! The flex PCB from OSHPark, I’m guessing? Looks incredible, though I’d dread wiring it.
And no reason a similar approach won’t work on countless other lights.
It’s a flex PCB, I shared it on Oshpark : OSH Park ~
But I don’t think the Attiny85 on the original driver has enough pins for RGB aux LEDs. Here I’m using a 6A buck driver I made for it : thefreeman's FWAA HDR 6A buck driver with RGB aux LEDs - Album on Imgur
Thanks. Yep good guess, wiring was OK using enamelled wires, much better than the thicker silicone wires, I’m never going to use those again, total waste of precious space. And yes I think the flex PCB wrapped around the MCPCB is quite versatile.
Thanks! I guess I need to learn how to design Oshpark PCBs. Is there specific software you use?
I use Kicad.
Thank you, again. Lovely work.
It looks wonderful! My single-colored aux looks a bit poor now.
Nice!
I used Oshpark for my designs years ago. How is it now - do they handle customs and tax for me?
Thanks, nah it’s very cool as well, especially with the air wiring.
Thanks.
They do, they charge VAT and are registered to the IOSS, but it doesn’t work (at least in France), and I’m asked to pay VAT and customs fees at the delivery (whereas there is no problem with e.g. Aliexpress), thankfully there is a form for declaring that taxes have already been paid for, I just give the invoice (with tracking number) and the form to the postman and I don’t have to pay anything.
Good to hear, I´ll give them a try …
I purchased a broken Zebralight SC600W from Azirine which had been dropped and didn’t turn on any more. After resoldering the component which had broken off (a little tricky to do at the far end of the battery tube) it was working well, but I wasn’t a fan of the fairly dated and cold white XML emitter it had. After a very ugly job trimming an old MCPCB with a test SST-20 on it, it now sports a 219b sw27 emitter instead! While I don’t think this is the finished item, it works well for now.

Have you ever tried Teflon wires? They are a lot thinner than silicone wires and very durable. I’ve used them with my quad E17A builds to save on space.
