Thanks, everybody!
Oh man, I have to follow that wild mod?! I trimmed and shimmed a reverse click switch so my SingFire-75B would tailstand, put a piece of diffuser material between the reflector and the lens and pencil modded the NMM cap⌠It is my new go-to indoor light for after dark toilet trips.
My first published mod, go easy guysâŚ
What does it mean?
And how have you manage to trim switch boot?
The âfirmwareâ for this flashlight has Next Mode Memory. Every time you turn it OFF it remembers what mode it was in, next time you turn it on it skips to the next mode, very annoying. It can be forced to quickly forget by tracing a pencil lead over the capacitor that holds charge to the IC.
I didnât mod the switch boot, but the switch itself. I just cut enough off to clear the barrel(?). When that wasnât enough to clear the switch boot, I put a ring of Venician Blind cord between the boot and the lip it sits on. Hope that helps!
Nice mod as a first published one WARvault. 
I like that flashlight, I have one from when it was still Ultrafire branded.
WARvault, thanks. Nice mod
Hi and welcome WARvault. You come from a nice area. I went to a school camp there around 1975. I guess things would have changed a little since then. Nice mod. 
BLF A6 driver into a Convoy C8. This simple mod took me about 15 minutes.
âŚand you got instant improvement in user interface and output
The C8 is a better light with the A6 driver.
I did the mod for the user interface. FET was a bonus.
Thatâs why I prefer Biscotti driver⌠3A regulated output and customizable interface.
Simonâs drivers became my first choice some months ago for any simple light (S2+, C8, any tail-click li-ion only lightâŚ)
Maybe you know then if the biscotti drivers that Simon sells at this moment have the corrected firmware? I have been waiting for a year now for confirmation of that.
My C8 came from Gearbest with the old 3/5 mode firmware.
I saw that Simon is selling drivers with Biscotti. â shrug â I made a choice.
Iâm pretty happy with the C8 with A6 driver. Donât see any reason to change it.
Jos, do you have any info on what should be corrected?
I bought one driver with Biscotti from bg last year for an S2+, the UI is much better then the 3/5 mode and still regulated 
What should be corrected ? I donât recall of any problem ?
The first batch of biscotti drivers had something wrong in the firmware (a âfuse settingâ), making the PWM frequency twice too high, and also the timings of any events in the UI. Getting into program mode was difficult, and maybe the modes were affected too, canât remember. Annoyingly, because superficially there seems nothing wrong, Simon kept selling those drivers and putting them in his lights. Even the desert tan S2+ that came out half a year later have (sometimes?) drivers with wrong firmware. He may even never corrected the firmware? I donât know because it canât be found on Simonâs site and no one ever took notice again. I just know that I really want a stash of biscotti drivers but only if it has the corrected firmware (I can not re-flash drivers).
The ones I bought were easy to use, all of them were 8*7135 if that changes anything.
No problem getting in config mode, nor setting the correct group.
I didnât see any complain about them, so I would guess that itâs gone now ?
But Simon sells biscotti drivers with less chips too, there may be some left of those with wrong firmware. I can get answers in the form of âprobablyâ and âmine seems fine, bought then and thenâ, but a year ago i bought 12 drivers, all with wrong firmware, and I would really like to be certain if I buy 10+ drivers again.
I totally understand thatâŚ
Sorry, I canât help you more than saying âmine are fineâŚâ
I just looked on Simonâs site,and there is a 7135x3,4,6 or 8 driver with ânew firmwareâ.It has the ui map,so i presume it is Biscotti.Convoy .Hope itâs the right one.
