DC pumps

[_Adrian_]

This is what I don't get about "engineers"...
Why the HELL would you mount a heatsink at the back of the unit where there is little to NO airflow when mounted ???

The current plan for mine will be simple...
An SPI controlled 6CH LED driver ( PWM ) that in turn will drive 4x 25A SSR's ( Solid State Relays )

This way interfacing to a Arduino or any other micro controller will be as simple as a few lines of code

Spent the better part of they day working on THIS.

Hoping to finish up the light main board and tomorrow and then move on to the DC pump control section and heater controls.
