WiFi controllable motors for your many projects. An Open Source platform that anyone can use. Using our motors is as simple as joining your motors network (or adding the device to an existing network) and controlling it with any of our apps, its built it webpage, or just raw JSON packets. Our motors are made […]
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. […]
Exploring Eagle CAD ULPs #4 – Renumber The Parts Number In Order
https://www.electronics-lab.com/exploring-eagle-cad-ulps-4-renumber-parts-number-order/
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 structures and to […]
Tools for the Electronics Hobbyist Part 2- LC200A L/C Meter
https://www.electronics-lab.com/tools-electronics-hobbyist-part-2-lc200a-lc-meter/
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 deal with a Chinese website like Taobao or maybe because […]

DIY Altimeter using a NEO UBLOX GPS module and a Color OLED
https://www.electronics-lab.com/diy-altimeter-using-neo-ublox-gps-module-color-oled/
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 sale. Also its […]
Measuring the speed of light with electronics
https://www.electronics-lab.com/measuring-speed-light-electronics/
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 history. In the course of measuring the speed […]
Inductive Proximity Switch Using TCA505
https://www.electronics-lab.com/inductive-proximity-switch-using-tca505/
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 resonant circuit and the amplitude […]
