HOW TO PROGRAM A REALLY CHEAP MICROCONTROLLER

There are rumors of a cheap chip that does USB natively, has an Open Source toolchain, and costs a quarter. These aren’t rumors: you can buy the CH552 microcontroller right now. Surprisingly, there aren’t many people picking up this cheap chip for their next project. If there’s no original projects using this chip, no one is going to use this chip. Catch 22, and all that. Like a generous god, [Aaron Christo ...

Getting started with NodeMCU development board for IoT

Since Internet of Things (IoT) projects are now quite popular, I recently bought a NodeMCU board to try IoT application development. The NodeMCU development board is an open source board based on ESP8266EX microcontroller with integrated Wi-Fi transceiver. Uploading programs to NodeMCU from any computer via microUSB port is very easy as it supports several programing languages. This makes NodeMCU a smart ch ...

Semiconductor radioactivity detector

Currently I'm trying to make a working version of a radioactivity detector that uses semiconductor as a sensor. It's a different approach than Geiger-Muller detectors or ionization chambers, more complicated, but also much more interesting. While Geiger-Muller counters can only provide information about the amount of particles in a period of time, semiconductor detectors can also measure their energy, so it ...

Wemos Lolin = ESP32 + OLED on one board

For the long series of articles documenting My Journey into the Cloud I used two small evaluation boards, equipped with an ESP32 32-bit controller, an antenna and a micro USB socket (the latter also serves for power supply input and provides a path for uploading programs). For newcomers, the controller can be programmed using the intuitive Arduino IDE, because the board manufacturer Espressif has provided a ...
