A dual sensor fan controller build
https://www.electronics-lab.com/dual-sensor-fan-controller-build/
Kerry Wong has designed and built a dual sensor fan controller: To make the design more useful, one channel is marked as optional (see components with * on the silkscreen) so that you can build either a single sensor fan controller or a dual sensor one. With two sensors, the control signal is or’d with both […]

Creating footprints in KiCad using a scanner
https://www.electronics-lab.com/creating-footprints-kicad-using-scanner/
Jan @ jasiek.me decided to use a flatbed scanner to trace out a footprint in KiCad. [via] Some time ago I sourced a number of very cheap SD card sockets from China for a hobby project I was working on. Sadly, when it came to PCB design, I couldn’t find the footprints for this particular […]
App note: Engineering scaling
https://www.electronics-lab.com/app-note-engineering-scaling/
Scaling large values to be fed on limited input digital meters, application note from Murata. [via] It is oftentimes necessary to attenuate “large” input signals down to a level that more closely matches the input range of a selected meter. For example, suppose the signal to be measured is 19 Volts, and the input voltage […]
Improvement in the resolution of Retinal Prostheses
https://www.electronics-lab.com/improvement-resolution-retinal-prostheses/
Denis Meyer @ elektormagazine.com discuss how the researchers improved the resolution of retinal prostheses. A retinal prosthesis substitutes for the photo-receptor cells of the defective retina. It’s composed of a camera carried in spectacles; electronics that processes the camera information; and a matrix of microscopic electrodes implanted in the eye in contact with the retina. […]
