31.05.23 Put ESP32-Tux on Tindie and got promotion by [hackster.io](https://www.hackster.io/news/the-lifex-esp32-tux-mini-offers-a-tiny-path-to-energy-harvesting-experimentation-with-an-esp32-c3-0470bf924f33) :-)  

03.06.23 Finished 12 ESP32-Tux Dev boards for Tindie orders  

This is an idea I had for some time after playing around with the ESP32 together with sensors, micropython and Phyphox. I started designing a PCB by my own for an ESP32-C3 chip. I want it to be as small as possible and also solar powered. The cube should be energy ,self-sufficient' and used for teaching physics. 

The cube should have the following sensors:

- Temperature, pressure and humidity sensor → BME280

- Gyroscope for acceleration and orientation measurements → MPU9250

- Optical/Light sensor (measuring Lux) → VEML7700

- 2 connectors for temperature probes (DS18B20)

- Voltage and current meter → INA219

- Time of flight sensor for measuring distances → VL53L1X

- optional: magnetometer & microphone for sound measurements

In addition the cube should have:

- OLED Display for showing current measurement data/sensor

- RGB-LED (e.g. for showing battery status)

- Push button for changing the sensor/measurement

- Solar cell and LiPo battery

- Pin-header for connecting to cube to a breadboard and use the GPIO Pins

- Mounting nut for placing the cube on a tripod

- On/Off-Button

- optional: buzzer for sound output

I aim for a 35x35x35mm cube with 3D printed case. The case should be robust - so that it can fall from a building and be undamaged... Hope to be able to do this project. 

My inspiration come from the [ESP32-Picoclick-C3](https://github.com/makermoekoe/Picoclick-C3), [BQ25504 Solar Cell LiPo Charger](https://hackaday.io/project/158837-ultra-low-power-lipo-charger-via-energy-harvesting), [01Space-ESP32-C3](https://github.com/01Space/ESP32-C3-0.42LCD) and the [Wemos C3 Pico](https://www.wemos.cc/en/latest/c3/c3_pico.html).
