Hey everyone! we are back at our desk, its toasty out so we're staying in during the day and cranking out some designs. one project we think we might be able to work on this summer is a de-zombification of the EZ-Link and EZ-Key boards from many years ago. these bluetooth classic boards rocked but suffered from using a really frustrating develop...

Desk of Ladyada - an ESPecially fun demo of web/wifi workflow

This weekend we've been noodling around with the new ESP32 support for circuitpython. The ESP32 doesn't have mass storage but it does have wifi, so we can use that as a way to connect to the REPL and also transfer files. This stuff is all very very new in circuitpy 8.x but there's a definition for the odroid go, and it's a handy board to use bec...

MMade progress on two RISC-V projects to finalize PCBs. We optimized the CH32v203g6 chip-based QT Py board by reducing it from a 4-layer to a 2-layer to cut costs, and integrated TinyUSB support for better Arduino IDE compatibility. We also advanced the Feather ESP32-C6 project, enhancing its deep sleep power efficiency and finalizing the USB Key 'Trinkey' for standalone gateways or sensors. Plus, we picked out a clear USB enclosure from Digi-Key for it.

Desk of Ladyada - RaaAWWwwwr PLEO battery repair

Part 2 of Desk of Ladyada! Last week, we tackled a battery issue with our old PLEO dinosaur robot by sourcing high-capacity NiMH packs from DigiKey. And, we'll look at the need for a specific 12V US AC/DC adapter with an 800mA output and a 3.5mm OD plug to replace the UK plug, ensuring the robot could be charged again!
