Hybrid Super-Caps – power for electronic jewelry?

Are Hybrid Super-Capacitors a good option for powering electronic jewelry. In attempting to find out I realised how little I know about the chemistry of these devices and how odd their behaviour is compared to plain old super capacitors – or LiPo batteries for that matter!

Is ArduinoJson Pointless?

Extracting values from JSON using ArduinoJson almost-always** takes many times longer and consumes many times more memory than just parsing the JSON “on-demand” every time you want to extract a value. RaftJson is an on-demand parser which is many times quicker than ArduinoJson in most real-world uses.

Investigating ESP32-C3 Power Management

While developing some electronic Jewelry I have measured the power consumption of the ESP32-C3 microcontroller to see if it might be a good fit for my needs.

Embedding Micropython on ESP32

Embedding MicroPython in an existing ESP IDF project turned out not to be so simple. So here’s a guide to how I managed to get it working.

Installing ESP-IDF on WSL2

I find that the Espressif ESP32 documentation for installing their IDF development toolchain doesn’t work for me on WSL2 without a few mods …

Pushing Z80 to the Limits

Asked enough times how to modify RC2014 processor boards to use all the BusRaider features I decided it was time to build one that works out of the box. With a few more goodies thrown in.
