An Engineer has been hired for this project. I want to thank all who applied and will keep your information on file.
Component selection and circuit design – contract bid
Component selection and small circuit design for PCB. The assembled PCB is to be contained within a 12mm diameter and up to 25mm in length.
Low voltage (3 to 9 volts DC) input with potential of up to 11 amps from rechargeable lithium batteries.
Controlled Voltage and Watts, based upon an external 1-3 ohm load (V, W monitored and adjusted by microprocessor, based on monitored load Ohms), circuit output values to be selectively displayed on a small digital display, circuit to be push button activated, and circuit duty cycle at 15 seconds. Circuit low voltage cutoff at 3.2 V. Small two digit digital display connected to PCB to be switchable between volts, watts, or ohms and push button controls to adjust V or W.
Need a couple of questions answered at first to determine options for circuit design and limitations.
