Desk of Ladyada - It's a RISC-V kinda weekend
https://youtu.be/aC3vGKHRCBA

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.

Desk of Ladyada - It's an RS-232 world, we just VINDRIKTING in it
https://youtu.be/viokTEHmqZs

This week, various prototypes, including an IR transceiver and an RS232 transceiver, while testing a USB Type C breakout. Additionally, BlitzCityDIY is working on IoTifying the IKEA VINDRIKTING PM2.5 sensor by integrating a custom board with an ESP32-S2 for easy IoT connectivity.

Desk of Ladyada - RP2040 Adalogger, C6 Feather, Floppy and some RS-232
https://youtu.be/FDbl3M8huwE

Tested the RP2040 Adalogger Feather and are now working on its tester. We're troubleshooting the Floppsy interface due to incompatible floppy drives. Progress continues on the ESP32-C6 Feather with TFT functionality checks. Additionally, we designed an IR transceiver, updated the HUSB238 Type C PD, and two RS-232 level shifters. We also revisited RS-232 transceivers, crucial in pre-USB communication.

Coming soon - Soil sensor gets a square wave update

After pondering the Multi-Year Soil Sensor Thread over at https://zerocharactersleft.blogspot.com/2011/11/pcb-as-capacitive-soil-moisture-sensor.html we decided to make another prototype of our revised I2C soil sensor, this time we'll use the square wave filtering technique rather than the RC-rise-time system.

@adafruit@mastodon.cloud avatar

We need a few more components to rectify/average the square wave signal, this is our rough draft. on the attiny816 we might be able to generate a 5 or 10MHz square wave. we also moved the AHT20 to be on a second set of pins we'll bitbang to read the temp/humidity. That way we can chain multiple sensors if desired.
