Nice Day For It

Try Again
Having all sorts of issues with the Twin Fuel Pump Control Board, so I did the mature thing and threw it all out. Time to start again.
Simplified the whole idea, got rid of the op-amp, and I am just using a single MOSFET. Bench testing of a bread boarded prototype is showing promise.
I have some new boards on order which will be here in about 3 weeks. I have to order a new MOSFET as the ones I have don’t turn fully on until 15.5V which is too high, although they will do for testing purposes.
Stay tuned.
Rain Light Project
The Rain Light Video is up on YouTube right now.
Fail
The first prototype Control Module is a Fail. The saying goes that you generally require at least three prototypes before you end up with a working device.
Well, I am off to a good start, as not only have I used the wrong Op-Amp, (It has an inverted output), I have also have the wrong ‘pin out’ on the MOSFET.
I need to learn how to read a Datasheet obviously!
Control Module Update
The Circuit Boards for the prototype Twin Fuel Pump Control Module have arrived.
Assembly and testing will begin today, so keep an eye out on the blog or shoot on over to the YouTube channel, subscribe, and ring the notification bell, so you can be notified when the Video of the assembly and testing goes live.
Cross fingers!
