ESPNow connectivity for the Ikea VINDRIKTNING Most of the code is borrored from Hypfer/esp8266-vindriktning-particle-sensor that uses an ESP8266 to read from GPIO14(RX) and send via ESPNow to a EspNow Server (check debsahu/ESPNowMQTT), which sends it out to a MQTT broker.

Here I add WiFi LNK module to my ESP-TM2 Rainbird Irrigation System and add the Rainbird integration to Home Assistant. Once completed, I winterize the irrigation system for the coming winter.

Machine Learning in WIO Terminal (Seeed Studio) to recognize shake and roll two die using True Random Number Generator (TRNG) GitHub: debsahu/WIOCatanDieRoll Objective When WIO is shaken it will roll two die signifying a turn on Settlers of Catan board game Die roll needs to be completely random uniform distribution Die roll must happen when device is shook vigorously Hardware WIO Terminal (Seeed Studio) USB-C cable Software WIOImuTap: Uses in-built IMU to look for double tap to roll 2 die using TRNG EdgeImpulse: Upload and train NN using sensor data on Edge Impulse, deployed on WIO with live classification on serial port....

Radon Radon is everywhere, see map Naturally-occurring radioactive gas - causes lung cancer Inert, colorless and odorless Naturally in the atmosphere in trace amounts Outdoors: radon disperses rapidly Most radon exposure occurs inside homes, schools and workplaces Indoors: Radon gas becomes trapped indoors after it enters buildings through cracks and other holes in the foundation Can be controlled and managed with proven, cost-effective techniques Radon monitoring Hardware Airthings Wave Continuous radon monitoring Long term monitoring LEDs color – radon level Battery Operated Bluetooth BLE ESP32 - lolin D32 (can use any ESP32) MQTT Server - Mosquitto Software Python script to read values from Airthings Wave: Wave-Reader Home Assistant Custom Component: sensor....

Instead of sending data to services in the cloud, here we send sensor data to local InfluxDB database. Grafana is used to read data from InfluxDB and alert thresholds are set to send reactive alerts.

Check out Canvasyvibes Art on the inspiration for this project. I use a stained cedar picket fence, 3D printed letters and photo clip to create a personalized holiday gift.

Nothing new, trying to build something based on video on stranger parts We build a coil with magnet wire and connect them to a LED. The LED blinks when coil is placed on Qi charger.
