Made a tact switch (button) board. Standard 2.54 mm header pins fit on the back. Semi-universal as far as 4 pin buttons go. 4x4 - 6x6mm smd and through hole 6x6 should fit.

12mm dia with 10mm silkscreen guide. Any particular diameters wanted? So that cutting isn’t needed much.

Also did an smd only version with tiny tented (soldermask covered) vias. Set it in with RTV silicone around the edge and it should block water from entering the driver cavity.

2.54mm header pins. 2.54mm (0.1”) is standard pitch / pin spacing. There are also 2.54mm machine header pins (round pins) which usually cost a bit more. Normal (square) pins won’t fit into female machine pin connectors.
You can also get XH2.54 connectors. Same pins but shrouded & keyed to prevent plugging in backwards.

Cool! :beer: So that's 12mm square, and 10mm at the ring?

edit: Erm, I just now measured the SRK switch hole, the ID is .480"/12.2mm... so either 12mm round or add a second cut line outboard at 12mm. I can't cut/file (or even draw!) a circle freehand that ends up even marginally round to save my life.

edit2: The nicer/genuine SRKs have a 1mm o-ring behind the switch PCB in the bottom of the bore, the cheap ones don't even try.

Its 12mm round. I’ll do 12.2mm.

edit
12.2mm

Ordered 3x 15DD, 6x17DD, and 3x20DD

OH YEAH!

I might have to order some more FET’s…

:bigsmile:

Which board is this?

Now that looks awesome. Any feedback on the layout Comfy?

It’s the SRK FET 46 mm driver listed in the OP. It looks real sweet you guys.

AWESOME!!!

I see you cut a notch for “easy removal” :stuck_out_tongue:

Beautiful…just got mine in today and incredible soldering comfy! AWESOME, pure awesome!

Oh yeah and comfy…any problems with the 1.6mm thickness vs the 2mm of stock drivers?
Can’t wait for a “review” and stats of the board

That’s slicker than dear guts on a door knob. Do you guys think it will fit into an M6 as well?

What is the diameter of the driver?

46mm

I'm an Idiot lol. SureFire M6?

It would be real handy if the first post included links to the posts here at BLF pertaining to each individual project.

The 46 might not fit…but the 17 or 20mm will :wink:

The only little thing I can find is that the pin2/pin3 selector thing for the switch input could be tricky when removing/replacing the switch wires, if it's done at the driver (if you use a wire lead to bridge the gap, the soldering iron will tend to suck it up when removing the switch wire). But I tend to tear things apart and tinker much more than most 'normal' people, and I plan to still add a 2 pin header on the little switch PCB for that reason anyway, I don't like unsoldering stuff when I don't have to. That's a very minor thing and I'm weird, it will probably never be an issue.

Warhawk, I dunno, but Richard is going to be selling them, gotta mod one. Gotta! That driver is just compelling. I feel drawn to it like a moth to a flame. (And if you have seen me solder than you’d know that analogy fits perfect). I figured one of you knew. I will do a search on some of the reviews.

Matt, an idiot? Not from what I have seen. A poorly phrased question I will grant.

Good call. I thought about it but haven’t done it yet. Some of the work was done behind the scenes but there are certainly parent threads even for those.

I believe the M6 has a larger ID driver compartment than the SRKs, so if it fits the SRK it will fit M6 with plenty of room to spare. Drivers that fit the M6 will not necessarily fit the SRK (I think DrJones ran into that issue on the one he did recently).

In a SRK...

That capacitor kabob thingy smooth out the current so no whining?
