Powder toy needs new electronics. The exsisting ones are quite sad actually. The PUMP element is not helpful at all and there are no resistors not even a 10 ohm.So what it needs is a element called RSTR which removes or splits the SPRK by a tenth. so it isnt quite so hard to make circuits.I DEMAND MOAR ELECTRONICZ!!!!!
Theres also placing a sign with the text {t} if you don't want to make a complex mechanism for that.
As for electronics, the electronics menu is just about full already, any more and we would need a second menu. Not saying a second electronics menu would be bad, just emphasizing how much electronics stuff we already have.
The lack of more electronics is sad. Without voltage, a true TPT "computer" is impossible. Also without electro-magnets or moving parts true "switches or hard drives" are impossible to make, literally.
