A customized STM32-based environmental monitoring system that measures temperature and humidity using bare-metal drivers and displays the da
Access UART & USB serial devices over SSH from anywhere on your network - This device with a browser terminal, GPIO control, and no cables.
Compact DMM (Digital Multi Meter), measuring volgage and resistance (three range selectable).
Second only to an oscilloscope, this Laboratory-Grade Function Generator is a necessity for developing & debugging.
A novel approach to a crystal controlled function generator that uses thumbwheel switches to set the desired frequency.
Build this Wien Bridge Sine Wave Oscillator from LED Magazine January 1991
A frequency generator consisting of a comparator, an integrator and a triangle/sine wave shaper that covers 20 Hz to 20 kHz in one go.
You can replace the crystal by a push-button or a NE555, but after a reset you need more than 100000 pulses before you reach setup function.
A 1983 Wien Bridge Audio Oscillator upgraded to incorporate a uninterruptible power supply.
A all in one debug tool prototype
ESP32 crashed in the field? This SDK captures fault registers before reset, survives the reboot, and gets AI to explain the root cause.
Getting started with cheap (<15ct) chips like the CH32V003 can be overwhelming, in this quick tutorial you can explore examples.
