Hey I went looking for a Esk8 electronics/electrical section and this was the next best place, feel free to move it @BillGordon
This A/S has been sitting in its box for a while, I’m approaching it with a certain amount of trepidation, not because of the current drain when off, for storage I plan on maybe using @deckoz’s cool AS150 switch, but I like having a push button which is why I’d like to incorporate this too, maybe that’s weird too and that’s ok with me
After the battery drain furores for this and MartinSP’s A/S I know I may get some hate on proceeding and again s’ok, let’s go.
Typically FET-based anti-sparks have a very simple design which has pos/gnd in-out with a button connection, sometimes the button comes with and pre-wired so you can just plug and play.
In this case I had to dig up a little and thankfully found a diagram after a little searching, but before wiring it in, I wanted to test with a low voltage source and just walk around it.
The plan is to use it with my Trampa build which has a 12s4p pack of Molicel P42A, conceivably this could peak up to ~150Avwgich is well within the capabilities of this device.
Wiring is fairly straightforward, the switch operates on the pos wire only
The switch needs to be either hard wired or have a pin header added, I decided to go the latter way.
Here’s both sides of the pcb
I can relate this diagram to a 5-pin latching led switch in the parts bin and the 3 headers on the pcb
The one thing I am expecting trouble with is whether or not there is native voltage step-down adjustment for the led in the switch, the diagram above infers use of a resistor but not sure it’s necessary or what k
Before I blow a led in the switch, anyone know resistor rating or step-down voltage through the pins?
