I am trying to understand how exactly the voltage from a 1.5 V battery gets connected to a 1000+ V capacitor inside these disposable cameras. Is there a specific chip designed to act as a voltage amplifier and diode or do capacitors act as a sponge of sorts and directly connecting them to lower power sources allow for saturation?
After previous answers I have more questions.
- you state the current is transformed to AC with a transistor* embedded in the chip. Does this mean I could get the same result with a suitable market transistor (and other components*)?
As my direct intentions for the hack are to use an increased voltage supply to drive a motor from a smaller set of cells (18650 to be exact) and I am aware that power is always lost during any conversion, would it maybe be best to use an AC motor such as a furnace fan I have rather than the 12 V scooter motor I intended to use?
Assuming I were to go with the AC alternative I would presume I would substantially be building an inverter, while I have had trouble with these being limited in their output to under 100 W, I suspect this may be mostly due to compenent costs and limits to ensure certain commercial safety ranges for delicate electronics's safety, as the whole point of this circuit will be to drive a motor some of those parts may be omitted?
I have APX30 18650 cells at my disposal and I prefer to keep them in smaller banks of 2-4 cells per set. I have an Arduino with relays I could use to switch banks.
What would be the easiest method (i.e. specific parts and general wiring preferred) to deliver the energy to get this motor running as well as possible?
Particularly, as I believe the fan motor calls for something like 20 A, I would presume I may need multiple transistors in parallel. If so, would I then need to bridge one of the legs on each to ensure they are all switched at the same time to the same phase, or would it need to be more complicated than that?
The intent is to build a motorized cart from bikes and other materials.
