Boris Landoni @ open-electronics.org documents his UV index detector. It measures solar radiation and visualizes the corresponding value on the integrated display of a miniaturized Arduino, in order to tell us when to expose ourselves to the sun… Open Source UV Index Detector – [Link]
SEPIC/Ćuk converter sprouts second output
https://www.electronics-lab.com/sepiccuk-converter-sprouts-second-output/
by Gheorghe Plasoianu @ edn.com Many applications require positive and negative supply voltages, with only one voltage requiring tight regulation. This Design Idea describes a dual-output, hybrid SEPIC–Ćuk converter whose positive output voltage can be lesser or greater than the input voltage. The unregulated negative output is a mirrored replica of the positive output. SEPIC/Ćuk […]
Reverse engineering the 76477 sound effect chip
https://www.electronics-lab.com/reverse-engineering-76477-sound-effect-chip/
Ken Shirriff has written an article on reverse engineering the 76477 “Space Invaders” sound effect chip: Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used […]

Printed Two-Dimensional Transistors
https://www.electronics-lab.com/printed-two-dimensional-transistors/
Researchers from AMBER (Advanced Materials and BioEngineering Research) and Trinity College (Dublin), together with the TU Delft have succeeded in producing printed transistors, which are made solely from two-dimensional nano materials. These materials have characteristics with much promise and, importantly, can also be produced very cheaply. Possible applications for this procedure are food packaging with […]
