Awesome, thanks so much for the help. A power screwdriver arrived on my doorstep today in fact. After disassembling it, I drew up a diagram with the major components for you to reference. This is a Black & Decker LI2000, if anyone's interested.
Aside from a li-ion charge protection module...
Thanks for the response, I realize I'm extremely out of my depth with electronics here, hence why I'm asking for help. I'm currently only interested in making proof-of-concept prototype. If this project goes beyond an initial product pitch, I'll be hiring a proper electrical engineer to handle...
I have a new question regarding the voltage regulator portion of the circuit.
I've updated the design to run off of 2 li-ion 14500 cells(so 7.4V nominally). The plan is to regulate that voltage down to 3.3V and run this motor.
I bought two of these voltage regulators, and I realize now that...
Hi there,
I'm currently designing a handheld, motorized device and I unfortunately don't have the knowledge about circuits/motors to know how to resolve the issue with my first prototype.
A little about the device: I'm powering a 37mm geared and brushed DC motor at <6V by means of four AAA...
