Lexel will contact you through the PM (Personal Message) system. He’ll get all the details and you pay through PayPal.
excellent, thanks!
I always say PM me, I don’t keep always track of my topics, but PMs get an E-mail alert
PayPal is the most common way, but also bank account can work
I got a lot done this weekend on drivers and Aux boards
Finished fitting my Lexel driver to my MF04S today, running Anduril - happy customer here.
Just wanted to say that my current set of EDC lights and my “soon to be finished” modded light are all using Lexel’s drivers with Bistro HD OTSM firmware.
I am using 15mm, 17mm and 22mm drivers !
Thanks for your work
Oh crap again one AMC not working on a driver
Bugger isn’t there a way to identify without removing one by one soldering?
Yes there is in fact an easy way if you got an IR thermometer or camera or very sensitive fingertips
Wow, so sometimes they just dont work at all?
How would you suspect 1 of 6 not working, by turning on a level that’s 100 duty cycle on them and measuring the current?
Maybe pouring some rubbing alcohol and watching it evaporate would show the one not working? On 5 it evaporates quick, but on one it evaporates slower.
Alcohol evaporation or Ice spray frosting the driver should work as well,
but if you got a part that does not have such a high power loss then often the IR camera is last hope to see less than 1 °C difference, like a dead short inside a MLCCapacitor
I had those bastards on one or 2 drivers, before I had the IR imager, can be a real pain to find on boards that are not typical drivers that contain only a few
This one was my fault, I secure back side with SMD glue, so they stay in position and don’t move outwards during the reflow,
when I placed the AMC on the board on the pad it moved quite a lot outside and smeared the glue to the whole ground pad,
effectively disconnecting it, first time this happened, but one of the small legs not connected happens sometimes
as I always test my drivers on my Rigol DP811 PSU, so I see with Bistro drivers if all AMC delivers the right current in Mode ALL AMC,
on ramping drivers it’s hard to notice at all
Arrow going crazy on component packaging and shipments
Long story short
I ordered parts for around 52$ for free international express shipping
3 Parcels now, one Netherlands, one USA and one China
all with Express shipping and DDP, 2 times DHL one time UPS
and they even pack 200 47k resistors I paid 23 cents for in a box likely more expensive in a single parcel
and for 10 Attiny in MLF package a whole tray used
Much more efficient when ordering from Mouser, MLF in a small ESD box and any non ESD stuff in a zip bag
Yea, Arrow packaging is so ridiculous that I don’t even want to buy things from them. You wouldn’t believe the massive stack of boxes on my porch and all the plastic trays I had to discard just for a smallish order of chips and leds and stuff. The resulting pile of trash was actually guilt inducing. They have to be losing so much money and it makes no sense.

Made a new LED block for testing driver
As I had often dust burning my domes I wanted to seal it
upgraded the heat sink significantly in thermal mass and cooling power using a used air tunnel cooler that has a solid 10mm top plate
Disassembling old and marking the new holes, had already soldered the heavily stressed 12V XHP70.2 to a Lumintop GT MCPCB
Holes drilled and a bit sunk
Cut threads and applying thermal paste
MCPCBs prepped for good contact
MCPCBs mounted
Tried to cut a piece of AR glass lying around didn’t work so well, used hot glue to put all together
Very cool, just keep in mind that using the notches on the edge of the mcpcb is not going to press down near the center like a reflector will. I’m a little worried about that xhp70.2. Maybe its massive size is good enough to keep it alive.

I pushed the MCPCB around the LED with like 30kg a couple of times and the paste came out on the left side where I cut a bit away from the MCPCB
I cleaned all the pushed out thermal paste with alcohol and tooth brush, all the MCPCBs had quite some paste pushed out
Anymore of these available? I take one of these.

I do believe that Lexel is “on hold” currently, as you can see by the time he hasn’t signed in. So maybe you won’t get an answer soon.
Hopefully he is well/recovering and hopefully he’ll get back to BLF someday, he’s a great asset to this community :+1:
Wow, it’s been two and a half months. Let’s hope he’s okay.
I hope he is well, if anyone else has drivers please let me know! Thanks for the heads up guys.
iam new to this forum
how can i buy astrolux s42 driver
First off, here’s hoping Lexel is ok
If / when this is available I’d like an Anduril one 38.5mm Courui D01 with 3 inches of each wire. For use with an e switch.
I’d also like some advice if possible what leds this will run? I’m looking at an xhp50 3v presumably this would do it? sorry I did try to understand it all but it’s over my head
