This is part of a science project: I would like to hire a talented individual who can design a schematic for a compact circuit with the following specifications: Circuit schematic should be compact: schematic should be flexible enough to be rearranged in an area that is smaller (or about the same size as) a deck of cards. Production cost of this device should be no more than $30-40USD, so please design an efficient schematic using economically affordable materials. Specify *input 9v DC battery *output: Waveform square alternating current Output Voltage +-50 V peak into 1k Ohm load, with a variable control mechanism Output Pulse Rate (Frequency) 180 hz pulse width approx 250microsec This should be a relatively simple project, don't overthink it. Compensation is negotiable.
