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...

Welcome to the 4th post of the “Exploring Eagle CAD ULPs” series. Every week we will publish a new post about one useful ULP in Eagle CAD. “ULP” User Language Program is a plain text file which is written in a C­-like syntax and can be used to access the EAGLE data...

When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpress and Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we...

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...

The speed of light in vacuum is a well-known universal constant and is considered to be the nature's ultimate speed limit. No matter, energy, and information can travel faster than this speed. The speed of light has always been a topic of great interest and significance throughout...

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...
