Therm: a Tiny PID Controller
https://www.electronics-lab.com/therm-a-tiny-pid-controller/
by Ethan Zonca @ protofusion.org: Therm is a very small PID controller with an OLED display, thermocouple interface, and USB port. It can switch an external solid-state relay for driving large loads, or a transistor for driving small loads. When attached to a computer, it enumerates as a USB serial port for easy control and logging […]
Visaton Exciter – an exciting loudspeaker
https://www.electronics-lab.com/visaton-exciter-an-exciting-loudspeaker/
A loudspeaker without a membrane which can be mounted on any flat surface solves aesthetical and technical problems. Fans of HiFi sound and similar „audiophils“ usually don´t cover their loudspakers and surely not their membranes. Firstly, to cover a beautiful top-class loudspeaker is almost a sin 🙂 and naturally all that stands in a way […]
PCA9550 LED Driver With Programmable Blink Rates
https://www.electronics-lab.com/pca9550-led-driver-with-programmable-blink-rates/
This project introduces the use of PCA9550, an LED driver that causes the 2 LEDs to ON/OFF or in a flashing state at programmable rate. It has 2 selectable, fully programmable blink rates between 0.172Hz and 44Hz or 5.82 seconds and 0.023 second respectively. Its internal oscillator does not require external components and I2c bus […]

The Simple Scalar Network Analyzer
https://www.electronics-lab.com/the-simple-scalar-network-analyzer/
by rheslip.blogspot.com: After playing around with the SynthNV signal generator/power detector discussed in the previous post I realized what a useful a tool it is for RF testing. While its a terrific tool for VHF/UHF/Microwave testing, the SynthNV has a couple of serious limitations for amateur use in the HF region – the signal generator […]

EA DOGS displays – small by size, big by features
https://www.electronics-lab.com/ea-dogs-displays-small-by-size-big-by-features/
Minimum power consumption, very good legibility and a lot of versions – these are the EA DOG displays. When we speak about “versions” – in case of EADOG from company Electronic Assembly it means a lot of “glass” types (STM, FSTN, transflective,…) and what is unique – many s display + backlight combinations. Right thanks […]
