ok…after my last how to on attaching a second MOSFET to handle the motor current and protect your primary MOSFET with all the sexy fire modes there were a bunch of questions about how to do this for other blaster models…
My original working solution was done whilst I was building an active brake which worked a treat but might be a bit confusing for the non tech savvy to get with the program.
The previous how to was done with a store bought active brake which changed a couple of things and…well…that screwed the … on me…muppet moment…
things you NEED to be good with
- Blaster MOSFETS are usually negative switching…that is they turn the negative motor wire on and off
- To test this, use your multimeter and check that the positive battery terminal and the positive motor terminal have a direct connection - this will indicate you are indeed negatively switched.
- Store bought active brake MOSFETS are usually positive triggered
I have opted to use a small reed relay which will make it easy for anyone to do this on any blaster.
Questions regarding steps should probably go with the progression images for the benefit of everyone and organisation of the brain dump.
