Hello
I have a new question as a followup to my timer circuit motor control.
I am making a capacitor powered torpedo to be used in my r.c submarine, this is ALL that can fit in the small torpedo compared to the other large one.
So the capacitor discharge rate determines the run time and it is a smaller torpedo so weight is a factor.
It will use either:
1uf/2.7v electrolytic capacitor OR 10uf/3v electrolytic capacitor
Reed switch NC and open no power with a magnet near
Small DC brushed motor
Here is a basic charging circuit I found:
The Low voltage transistor: TLV2217
Would a LM393 be the same????
O.K my question is, in the above circuit, the capacitor is charged up and during the charging you can here the motor speed up until release and it goes on it`s way.
Question, Can this circuit be modified so that it charges the capacitor to a safe Max. Voltage then stops charging without blowing up?
Can I have a small LED display showing the charged voltage amount?
The main battery source for this charger is 4 -- AA batteries OR I can go to a Lipo battery as the main battery if you recommend it.
This would be portable in a little hobby box
I would also like to have a Power On / Off switch with LED light indicator
Overall I would like to keep this as Small as possible and as low cost as possible
Sorry for the big picture above.
Can you show a circuit with parts in your reply?
Thanks in advance again.
George
