You can build something cheaper and more customizable with an ESP32 or a Raspberry Pi, and that's what I did. It's beautiful, it's easy, and incredibly versatile. If you want to get started, I'll be ...

Unexpected Maker has recently released the Series, a lineup of four new ESP32-S3 development boards: the EdgeS3, TinyS3, FeatherS3, and ProS3. The boards ...

An Arduino Nano is in charge of reading the sensors. When it appears the car is approaching a wall or similar obstacle, it fires off a PWM signal to the car’s motor controller commanding it to ...

This repository contains an ESP-IDF board support package for Arduino Nano ESP32 board. This board is based on an ESP32-S3 chip. This component includes the blink example. It can be used as a starting ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for super cheap, and they're incredibly versatile. When you're done using an ...

Made from an ESP32 Beetle C6 and using an attached accelerometer with simple thresholds the Piko can detect if you’re idle, walking, jogging, or sprinting; and at the same time count your steps.

I would like to request the integration of the MOD-IO and MOD-IO2 modules from Olimex. They work over i2C, usually connected with UEXT cables to ESP32 board from the same manufacturer. They offer ...

High-responsivity and low dark current resonant-cavity-enhanced (RCE) Ge PIN photodiodes with a monolayer graphene absorber were demonstrated on a 200 mm insulator. Ge was grown on the donor Si wafer, ...
