ANALOG EFFECT: This week, I completed the Analog Effect circuit (a 3V3 clone of the Colorsound Overdriver). By importing WAV files into SPICE, I was able to verify that the circuit produced the intended modulation effects, and was not functionally affected by my revisions to make it 3V3 compatible. This gave me the confidence I needed to implement the circuit using real hardware in the Rev 1 Schematics.
REV 1 SCHEMATICS: As planned, I spent the majority of my time this week on the schematics for our Rev 1 board, a near-complete prototype of our project hardware which has fewer audio channels but contains all of the necessary peripherals. I have sourced essentially every component in the design, and I am filling out a BoM for delivery to PCBWAY in conjunction with the schematics.
Currently, the schematics are approximately 90% complete, pending feedback from my teammates and a few small changes. The plan is to complete the schematics in the next few days, followed by a design review with our TA / advisor. At that point, I can begin laying out the PCB with a goal of sending it out for manufacturing by around the end of the coming week. This will enable us to verify our software on actual hardware.
In the coming week, I will also be preparing to give the Design Review presentation, which is my designated presentation to give.
90%-completed schematics are attached to this update.
