Just for fun, I built another lightsaber between building v1 and v2. It was more of a test platform to see what I could do with PVC tubing as a hilt material. Most intriguing was trying to make a curved hilt much like Count Dooku. I also wanted to try out different ways of mounting the blade. An unexpected finding of v1.5 was realizing how much voltage drop affected the LED string, which is something I fixed in v3. Here’s a couple pictures.
Added core support for the CH32X035 along with USB FS, USB PD, ADC, and UART drivers. Supporting other CH32V parts will be relatively straightforward.
First time using a RISC-V microcontroller, iCE40 FPGA, and an LTC2320 ADC. It streams 8 channels of differential 16-bit 48kHz ADC readings over USB as audio.
Developing for CH32V using 100% open-source components, true to the essence of RISC-V.
While still lacking in many features, I’ve added just enough support to get the LPC845-BRK and my own LIN breakout working.
