Jayson’s Status Report 02/07/26

This week I designed the interrupter for the Musi-Coil, primarily focusing on component selection and circuit layout. After significant research, I decided that the best option was to modify a standard 555-timer based interrupter design, where the control voltage to the timer takes input from a 3.5mm audio jack with a series capacitor in order to offset bias voltage. I also was sure to add a capacitor between the 3.5mm audio jack’s output and ground to protect whatever device is being used as an audio input. I am still working out what the driving circuitry for this 555-timer will be, but the current plan is to have the 555-timer act as an amplitude modulator, where its output is a carrier signal for the musical audio. Next week will be spent primarily designing that circuitry.
