Could I possibly design a board myself, and purchase a pre-flashed MCU from you (or perhaps just purchase the firmware to load myself)?
I want to build a RGBW P60 drop-in, and I just want to cycle through the colors in a set order at a fixed brightness for each so have no real need for a momentary switch operation. The mode order I'm thinking of is White > Blue > Red > Green > B/R > G/R> back to start.
The B/R and G/R mixes will be pre-determined fixed ratios.
Possible? What MCU you are you using in the picture in the original post? I have designed a 17mm P60 driver using the Attiny84 (haven't ordered it yet nor do I have the MCU either), but it is a bit bigger than the one used in the first post.
Not L4 because it's big and more of a thrower, and 'throwing' doesn't work well with color mixing. For color mixing you want a strong diffuser, so the big head is useless. BTW, the driver (probably) also fits into the Roche X3.
Mattaus: Such a simple clicky firmware could be done on an ATtiny13; sending a PM.
Ooh, I hadn’t thought about the Roche F6 as a compact host with a momentary switch. How hard was it to mod, and to get different guts into? Any easier/harder than the ZY-T29?
Designing a specific driver for it takes some effort, but when you have that it's fine. The space in the driver compartment is quite small, so don't use long/thick wires with the RGBW.
DrJones, is it practical to take the IR measurements any faster than the 10s interval you’re using here? I’m wondering about idiot-proofing high powered AA lights against alkaline usage. If I could quickly measure internal resistance on startup and maybe lock out high power modes if IR was too bad that could be useful.
I made a custom driver board for the cheap Yupard 16340 light, too.
And here are the Roche F6 and the Yupard with some nice diffusers; multi-vitamin carbon tablet tube, imprint sanded off, with some layers of tape inside the opening to reduce the diameter, so it can be easily put on and off the flashlight.
Heheheh, pretty sweet! Light dagger is a neat concept, actually. It may be something that’s already been visited in the Star Wars Expanded Universe, but I have no knowledge outside the films.
Ok! it is next year. Even more, it was published in 2013…
did you change your mind and plan to sell the complete driver? are wet here yet?are we there yet?
yo did a great job here!
Made a board for the Shilhunt H02/H02R. With this board I had enough space to add another 7135, so I made white run at 1A for more brightness. Now this is much better than the H02C which has only very simple modes.
Since the H02 TIR is actually quite bad at color mixing (that's why the H02C doesn't offer any color mixed modes), I used the H02R and d-c-fix diffuser, much better.
A light emitting to the side and a bike mount like this allow mounting to a bar pointing in any direction (due to the 2 perpendicular swivel axes), very flexible. And of course the magnetic base is very handy. This H02R-RGBW is my favourite RGBW light. One drawback though: Those cool 'light dagger' diffusers (see above, #35) don't fit.
