I agree that the process is too time consuming for such a low price. Of course, if you’re doing multiple items, a lot of that time can be divided. But, even if you optimized it to the best possible, your price of 5.7€ is too low for such hand work.
Sad but I had to increase the prices, as they took a lot of work to build
I thought I may subsidy with some profit from drivers but calculating shows I am making still a loss
rev 3.1 is now available
one more full battery indicator outer LEds added, default is green but can be changed
LVP now shuts down the boards completely, LDO and voltage dividers ect. get cut from power, even if that drain is just 20-40uA depending which board
I had an idea how to get aux boards to the D18, it would need replacing the front cover
have all LEDs flipped so they shine through holes of the PCB, while all components are inside
I was reading about your FW3A AUX boards. Are they ready? I am still waiting for the SST-20 FW3A version. But the 5000K LH351D are already waiting here. And the new 10509 Optic is ordered from arrow and shoud arrive in 2 days.
Each 0.35mm² conducts only a portion of the current and is a lot more than the copper traces on the MCPCB used
Connections:
you have to avoid crossovers of them as well, you can try thicker but no guarantee it will fit
in this picture one red supply is not connected to the middle, that would need to go also to the center
Thank you for the explanation, Lexel. I will see if I can get a new 2S MCPCB from Mateminco to make things easier. The aux board might fit better then.
I think a MCPCB is on BG for sale ridiculous expensive, its v2 6S so does not fit
I have here 1 2S/9P MCPCB stencil and emitters and 8 3S/6P (the only ones made before decision went to DD driver)
as I wrote I converted one from v2 to v3 with Aux board on top
does anyone (or lexel) have d4 instruction to remove the star or mcpcb so i can get to constant ground? I am trying to do a always on aux (already have in hand from lexel) with no firmware mod desired.
I’ve bridged the + and L with bare wire it sits just over the + from mcpcb, so that saves me one solder point. I just need to find the easiest location /way to get ground to aux board ground now.
