6. Batch "TA" 1S or 2S Bistro HD OTSM/NarsilM drivers 15-47.5mm size fit, S2+, C8, H03, MF01, MT03, Q8 Clicky or E-switch

you mean a normal momentary switch with a FET and a bi stable lock state?
never heared of such a thing, momentary is easy like I did in my remote FET switches

Oh, okay. The Ti tool uses them - Lumintop Tool Copper with electronic switch. Some members at cpf have made small runs of custom lights with them (kuku427, ShineOnYouCrazyDiamond, and Tain) though I have no idea where they get them. Just thought I’d ask :innocent:

Would the momentary in your remote FET switches be the same as having an e-switch tail?
The reason I ask is because if it does, then it’s only a step away from mounting an e-switch in the tail instead of having the remote pad.

I recently got a few budget lights with e-tail switches (whole driver in the tail) and really like those switches.
So I’ve been toying with the idea of converting a light to an e-tail switch with the driver in the head.

Been looking at this thread, it shows a good summary of the different methods that are possible: Mod - installing tailcap e-switch in SK58 (picture heavy)

One method is with the tailcap FET circuit, which requires a small battery or capacitor in the tail (like the Ti Tool)
Although personally I’m looking at method #4 (driver in the head) with e-switch firmware.

From my understanding the FW3A uses method #4. I think it’s kinda hard to retro fit that method to existing lights. I wish to modify some edc’s like my D25C, there is nothing wrong with the stock switch but for waking in the night I prefer a (near) silent switch.

The remote fet switches are only momentary action, meaning - push = light on / release = light off

The ti tool switch is what I want but it doesn’t need to be that small.

I noticed that the first two links in the first post go to Google and redirect. What’s up with that?

Lexel, are your boost drivers ready to be built?

The Bistro are working, but I got still some glow between blinks,
to address this a new board need to be made for NarsilM drivers as they do not shut down completely including firmware change which I am not capable of
The people I asked to change Narsil do not respond

I know Tom E hasn’t been posting much at all in the last several months. Have you contacted ToyKeeper or Texas_Ace? Maybe DEL?

It’s a shame if this project gets shelved, I second what JasonWW said. Have you tried pinging the forum driver firmware gurus besides Tom E.?

Does this mean that boost drivers with Bistro will be available soon?

Any update on the boost drivers?

Lexel, what is “rainbow rgbw” in line 37 of your table?

Lighted tail switch.
Bottom of post 3.

Thank you!

I’m looking at the Q8 driver (4p) for a blackshadow terminator. The stock driver is 47.5mm diameter. It appears it will work, has anyone tried this?
The BST has a lighted e-switch (4 wires) would this be compatible?

Is there room to drill a small hole in the center of the board for the mounting screw? Like this:

(Photo from this BST driver upgrade thread, the SRK driver’s diameter was a bit too small)

Technically you can drill in the middle no parts or lanes there, but you have to remove the copper on both sides to prevent shorts from battery+ to ground

Hey, Tom E showed back up on the forum. Have you tried contacting him?

He is not responding on my PMs for weeks, even a friend wrote Tom begging to help

Okay.

Thanks, assuming the green area has no copper… the mounting post under driver is 5mm and the nut (battery side) is 6mm, so the need to remove copper depends on how big is the area with “Q8” lettering in the center?

It will be much easier mounting to drill the center (if possible), but it may also be possible for me to use the 2 existing holes instead if I drill/tap two new holes underneath and find long enough screws, what is the diameter of the existing 2 holes?

Also, how thick is the board? And is the battery + contact ring thicker and stand out from the board? The BST stock board is 2.25mm thick and the batt + ring stands out another 1.75mm for about 4mm total height from the mounting lip to the + contact of the cells.

I assume this is compatible with a lighted e-switch? My switch has 4 wires, so I guess 2 are for the LEDs
