The flasher circuit was harvested from a toy. These flashing wands are glued together, and the batteries are "not replaceable". The only way to get inside one is to break it open. I've never successfully opened one without ruining the clear plastic...
The design currently contains four modules, including: Base module (with NodeMCU, breakout headers, 74HCT125N level shifter and external connectors/spots for DHT22 sensor)Power Supply module (with AC/DC, DC/DC and POE-level power supply options, to provide...

The whole project started after seeing a commercial for the toy on a Jaboody Dub's twitch stream. The meme potential was just off the charts. Hardware wise, it's an ESP32 running Arduino which plays audio from a SD card via an i2s dac+amp. Also there's...
Video Series The video series refactors the CPU from scratch and documents the details along the way. Running on an inexpensive FPGA card. IOP16B - I/O Processor with minimal instruction set Useful for offloading polled I/O or replacing CPUs in...
