hi dear,could you tell me why you want buy China items not via AE

[Serp]

This does not apply AE, but IMHO

1. Use in the driver Attiny 13A (45/85) microcontroller. As far as I know, you have a PIC.
This will expand the range of potential flasheholik for possible reprogramming. In this regard, the Convoy takes precedence

Flashlight Firmware Repository

I've been collecting flashlight firmwares into one place and I hope it can become a central place for everyone to keep their code. The repository is linked in my signature, or you can click here: Project: https://launchpad.net/flashlight-firmware Main code branch: https://code.launchpad.net/~toykeeper/flashlight-firmware/trunk Anyone can create an account, branch the code, upload modified versions, file or fix bugs, submit merge proposals, and so on. A quickstart is in the README (also incl…

2. make the driver with a FET transistor + AMC7135. For triple and flashlight on the new XPG3 & XPL2 LEDs - this driver makes sense.

3. Use the illuminated button. Even if you just change the PCB design for an opportunity to add LED and resistors…

D.I.Y. Illuminated tailcap

I’ll start by saying that while sometimes I’ll sell a light with one of these pre-installed, I am not currently taking orders for them. If someone else offers to build one for you, go for it. I won’t attempt to restrict it in any way, though I try to make it as accessible as possible for people to build their own. This is still a project in motion, often being updated/upgraded. So if you have an idea to make it even better, please let us know. Below is a brief overview. I recommend reading thr…

4. Use copper Pill Coated from oxidation (or without it) & DTP star.

Low-cost copper pills, spacers, optics, drop-ins (Updated 23/10/2022))

S2+ and S21a spacers are available in EU. You can get them directly from BLF member Chatika vas Paus: https://budgetlightforum.com/messages/new/24803?destination=user/24803 The following parts are available in United States.

5. The great interest will be the driver 6-12V output (alone or with flashlight) on a single battery 18650.
Nichiya released new diodes, also CREE have XHP35/50/70

[[ GXB20 Driver – Homemade Constant Current Programmable XHP50 Single-Cell Boost Driver! ]]

Hello all and glad to join everyone here at BudgetLightForums! Here's a weekend project that turned out pretty nice and I thought I'd share. Introducing the GXB20 Boost Driver! [image] * Above shows the assembled GXB20 v2. Note typo on silkscreen which reads 3V / 6A - should be 6V / 3A instead, spring not soldered on yet * TL;DR: I designed and made a simple constant current single-cell (e.g. 18650) XHP50/70 (6V 3A) Programmable Boost LED Driver. I’ve called this driver the GXB20. …
