My new BLF dd_PIC drivers UI allows short press for on/short press again for off.
I could easily mod Heloi’s design to accept the needed PIC MCU (and remove the unneeded voltage divider resistors) if you’re interested in that.
You can see a video of the bad ass UI and read about the standard 17dd and 15dd in the thread here. I am out of town this weekend but if he will send me the files I can have a direct fit driver for the F6 ready to order as soon as Monday. If I have to start from scratch it will be a bit longer.
I could also build the driver for you, test and ship it to you for about $25 USD.
Edit: really wish someone would atleast try one of these (and like I said if I could get any takers I’d be happy to make one direct fit for the F6 or anything else), I put a lot of time/work into designing, building and testing these things. Someone please start using them. The FW is much much more advanced that any modded version of STAR (but still extremely simple to operate). It’s disappointing no one’s even ordered a set yet… 
I’m not even pushing for someone to buy one from me, this is a dedicated open source project, just please someone install one in something!
