We are looking for someone to take a current design that we have and modify it for another use. The current circuit uses a mercury motion switch to turn on an RF tracking transmitter when motion is detected. This circuit uses an SCR to send power to the transmitter when the mercury switch closes the circuit. We would like to modify the design to eliminate the mercury switch and instead use digital outputs from another device to turn the SCR on and off. The new circuit should then have 4 inputs that can be used to turn the RF tracking transmitter on and off as will be described in our requirements document. After successful testing of the circuit, we will then create a second job to do the PCB design and would prefer to hire the same engineer.
