Much thanks !
Please send PM to me with your email address so I can send a paypal invoice.
Thanks, Tea!!
Will there be another DCB1 plus kit GB anytime soon?
Yes, for all boards.
For the DCB1, I am currently collecting parts to assemble the kits. I had an unexpected buyout from kits from one customer. Likely a micro-GB from Asia that I was unaware of.
there is one strange situation appearing here..
if we supply 18V and use a 3.3ohm resistor at the input so what we get is about 13.1V of output and current through the 3.3ohm resistor is 1.37Amps so now if by any chance the voltage increases then the current through the resistor also increases considerably that it gets to mosfet might burn state.
Using the reference leds total string voltage about 12V.
So now how to get the current through resistor constant irrespective of the voltage change? like about 20 to 30% of voltage change.

Vrset=Vgs-Vf(3leds). Stays constant depending on the Vgs curve set point. If Vrset changes with input voltage then something is not working right in the CCS. The shunt part 5 Leds Vref is about 10V not 12V. If 12V maybe something is wrong there. Try keeping the technical questions gathered in the build threads only by the way.
Send pm to tea-bagHi guys. How do I buy Reflektor-D and BIB (positive and negative) PCBs?
