Seriously impressive! Man, sure hope the FW3A evolves into a later version providing aux LED’s like this. I just don’t have the technical know-how to do it myself.
I did not use any additional board. I placed the additional diode centrally on the existing board and connected it to the driver.
I compiled the latest version (FW3A) of adruil with aux led support. Everything works very well :
Sorry if this has already been asked, but is there a guide with pics of the mod required and also a guide and firmware for flashing, hopefully including a good cable for the flashing?
The flashing process is pretty much the same as any other attiny85 based driver. Lexel has a bit of info and a precompiled .hex file in his thread where he is selling these boards.
You’ll need a USBasp, an SOIC8 clip and something to connect them (dupont wires are the usual recommendation). For instructions, there is a thread going up for the D4V2 and the instructions will be adaptable to the FW3A. The main differences between the lights are the method of connection (FW3A uses a generic clip and the D4V2 uses a special programming key), the chip being flashed (attiny85 instead of attiny1634), and the file to be flashed.
I think there is an old thread/post by Hoop on how to flash attiny based drivers as well. (they are all very similar)
You only need to flash if you want high/low/off. Lexel has a board with LVP built in you can wire up with no changes but you get 1 brightness level and always on.
I already have a board with secondaries, the one commonly used with Dragon drivers. That board uses a common + for the primary and secondary LEDs and separate ground cables.
Is there a driver mod and firmware for the FW3A to work with this board? I prefer to use it as I already have it and I also want to use a turboglow gasket between it and the optic, something obviously impossible if there is a second board in there.
So, I got a FW3A intending to turn it into a green dragon.
I got the Steve Ku trit button, a drilled for trits Carclo optic and filled them both with green trits. I got a dragon mcpcb with green secondaries and replaced the primaries with Nichia 219b sw45, which I prefer. Then oppened the light to see the driver board is a larger diameter and that it makes contact with the button via a tube, so I will have to keep the original driver.
It is a nice driver, with the Anduril firmware, for sure, but I want green secondaries on it.
I saw JC Customs offers FW3A lights with secondaries so I contacted them via Facebook and asked to buy a driver. I got an answer saying they do not sell drivers but I could send mine to be modified and flashed with the required firmware. I replied I would be interested in that and asked for the cost and the location where I should send it. I never heard back. I have send a couple more messages which have been received and also ignored.
I saw there is another option for a secondary board available for purchase and a modified firmware and instructions to flash it, but I really want to be able to use the turboglow gasket I got that fits the dragon MCPCB.
Does anyone know of a solution to my situation? I would be happy to do any required mods myself (hardware wise) and follow any instructions to flash any required firmware (and purchase the required cable / adaptor to do it).
