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 […]

Automatic Light Switching System with Dimmer
https://www.electronics-lab.com/automatic-light-switching-system-with-dimmer/
Manual switching of outdoor lights in houses or roadways can be sometimes really inconvenient especially when we are far away or still at work. Sometimes this becomes an opportunity for thieves to infiltrate houses or a possibility of accident in roadways if night comes and our outdoor lights are still OFF. That is why the […]
