I started another 5 driver builds.
Kind of like I do with all of my sewing, it makes way more sense to do the steps in batches.
3-22mm. 1-20mm. 1-17mm.
I think I may add another 20mm to this batch, as I want to test efficiency between 2 different mosfets.
I also pre flashed another handful of ATtiny25 chips lastnight.
I swapped out the stock driver on this Convoy M21b with one of the TA Fet+1+8 drivers I finished building today. LHP73b 5000k. Tenpower 21700 50XG.
Pulling 40.58 amps!
Might be a little overkill for this host. It gets hot pretty fast.
I built up another driver with the “after dark” pcb from Osh.
At first I wasn’t too sure how I liked the coloration, but it’s actually easier to read the silkscreen when placing components.
I also tried a different solder paste. Quickchip smd291ax50t3 63/37.
I tried to use it sparingly.
I think it came out pretty good.
I was previously using kester.
Where are the NV1010’s? (:
I’m sure they will be happy with all those amps!!!
I actually just received a Convoy order with a few NV1010’s. I plan on putting them in some DDH hosts with 16mm ROD OP reflector builds. 
Working on another batch of 22mm drivers for some hosts I have enroute.
I’m liking the quickchip soldering paste. It seems fairly easy to apply. I used it on all 3 of these, and the previous 2 drivers I built recently.
I also got some new cleanroom wipes and this neat Wolfbox Megaflow 50 compressed air duster to help clean after flowing solder.
The air gun is surprisingly powerful.
At least, if not more powerful than canned air, which I’ve been using way too much of lately.
It’s about the same price as a 12 pack of canned air, and it’s way safer for cleaning reflectors.
Those TA drivers, are they also available at oshpark?
Yes, they’re available on OshPark:
Thanks!
@Toaster79 Looks like @INeedMoreLumens beat me to it.
If you are planning on building these, I recommend to use a different FET, and otherwise follow the original build thread INeedMoreLumens linked.
The build list on OSH shows a 22k resistor for R1, but the digikey cart and OG thread show a 19.1k.
Use the 19.1k.
For the FET, this is a solid option. Digikey PN# BSC009NE2LS5ATMA1
Or if you are ordering stuff from LCSC this is a great option and way cheaper.
AOS AON6500
Edited to add: Also the Schottky Diode has been out of stock on DIGI, but LCSC has the exact same part, and it’s way cheaper. I actually just ordered a BUNCH of those and the AON6500 Fets from them last week.
DIODES ZLLS410TA
ALSO, the 17mm driver uses 0603 1uF for the OTC cap. But I use 0805 on 20 and 22mm.
I have used and tested both of those FETs back to back in identical builds and they perform the same.
Both recommended to me by @INeedMoreLumens
I can help you build a cart on Digi for clicky switch builds if you’d like, as everything I’ve personally used has been tried and tested in about 10 builds now.
For firmware, use Bistro Tripledown
Yeah, I was looking at those fet drivers and since I just got a hot plate the Idea of building them myself has crossed my mind since they’re single sided. But the TA driver would also work in certain scenarios.The digi key cart works for me and everything looks in stock. The more expensive fets don’t bother me either even after putting together a batch for 25 drivers. Thanks for the heads up about the resistor value and yes, if I decide to build these together with the switches you can rest assured I’m gonna pick your brain. Well everyone’s brain that’s involved 
I do have a question tho, could these fet drivers be used with clicky switch with proper firmware? Something like bistro instead of anduril?
Also I’m from Austria so digi key or mouser is gonna be most likely supplier
could these fet drivers be used with clicky switch with proper firmware
Absolutely. All of the TA drivers I have built have been for clicky switches. I use Bistro Tripledown. It is linked in my post above. Also, see my edit regarding the OTC cap and the Schottky diode.
I just got a bit confused hahaha since my mind was on top of the fet drivers but I was asking about the TA drivers.
No worries. If you’re gonna build any of the drivers I’ve posted in this thread thus far, do the TA for sure.
The basic FET driver in my first few posts is good, but the TA is way better.
I was gonna go for the fet+ first since the convoys 22mm is out of stock and Simon never answered my question about restocking those
For the Fet+ with clicky, I used the regular version of Bistro.
You could do a 22mm Texas Avenger instead of a 22mm Fet+ 
Just looking at it. Gotta find a reliable source of 7135 which is not gonna be easy in my neck of the woods.
Have you ever ordered from LCSC?
INeedMoreLumens turned me onto them. They are a great source.
Here are the OG Deathclaw 7135 chips for a steal. It’s all Ive been using for a bit now.
You could order everything you need from them. The AON6500 FET and Schottky diodes are way cheaper there than Digi as well.
Looks like I’ll use them for the first time.
I’m just looking for the part list of the TA driver. You wouldn’t have one handy would you? I’m just chewing through the TA tread and its gonna take a while before I get my shit together and build one myself There’s just to many ifs and ors involved
