help upgrading an old RC truck?
Ive got an old New Bright RC truck, i got it around 2000 so as you can assume the batteries arent very good anymore.
im not looking to repair the batteries though, im looking to upgrade the truck with a little bit of some newer technologies.
heres where i ask for help:
i dont want to overpower the control board in the car, since it may have adverse effects on how it performs, so i just want to up the power to the motor. i have some D2583 and B1658 transistors, i found a datasheet for the D2583's that says they are high power NPN transistors, but no such luck with the B1658's.
using the D2583's (i have 6 of them), i want to create a circuit that runs from the main board, and acts as a second H-Bridge (or some sort of control circuit) that controls more power, so i can safely run more voltage to the drive motor without overpowering the main circuit board.
does anybody know how i can do this?
i have attached a picture of the area on the circuit board where the original H-bridge is.
