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...

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...

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...

mikeselectricstuff @ youtube.com shares his wearable insulin tear-down. This is an interesting device to tear-down so take a look. Omnipod wearable insulin pump teardown -...

In this video educ8s.tv is going to build a DIY Altimeter using the UBLOX NEO-6M GPS module along with a color OLED display with the SSD1331 driver. About a year ago, I built some GPS projects using this GPS shield. This shield is great but unfortunately it is no longer available for...

This circuit is used to design an inductive proximity switch. The resonant circuit of the LC oscillator is implemented with an open half-pot ferrite and capacitance in parallel (pin LC) and if a metallic target is moved close to the open side of half pot ferrite, energy is drawn from...

Clemens Valens @ elektormagazine.com discuss about LTC3623 switching regulator which can be used as Class-D Audio Amplifier. Sure thing, Elektor has published several designs of adjustable power supplies based on switching regulators, so we know that doing this properly in a...

Max.K @ hackaday.io designed his own impressive watch based on Atmega328p with Arduino bootloader, Maxim DS3231 (<2min per year deviation),  96x96 pixel Sharp Memory LCD (LS013B4DN04) and it's powered by a CR2025 160mAh coin cell battery. Chronio is an Arduino-based 3D-printed...
