The PSLab provides an array of test and measurement instruments for doing science and engineering experiments. Its built-in instruments include an oscilloscope, a waveform generator, a frequency ...

I’m a big fan of the ESP-01 Wi-Fi modules. Because I’ve done a couple of Wi-Fi projects, rather than fiddle with pin headers and jumper wires while programming, I decided to get one of those generic ...

internet inspired esp-01 (esp8266) IO expander. This uses DIP (socket and replace if you oops) 74xx595 and 74xx165 chips to give you 16 inputs and 16 outputs from an esp-01 Why not just use i2c? WELL, ...

ESP-01 is a tiny and useful piece of hardware. It has a 32-bit MCU, 2.4GHz 802.11 b/g/n WiFi, 1MB flash memory, and several other useful embedded features. Such ...

What a time to be alive! The range of things you never knew you needed but absolutely must have expands at a breakneck pace, such that it’s now possible to pick up a belt buckle with an embedded LED ...

[Matheus Garbelini] just came out with three (3!) different WiFi attacks on the popular ESP32/8266 family of chips. He notified Espressif first (thanks!) and they’ve patched around most of the ...

The development of energy and cost efficient IoT nodes is very important for the successful deployment of IoT solutions across various application domains. This paper presents energy models, which ...
