Miniscope v2f
https://www.electronics-lab.com/miniscope-v2f/
Here is another variant (after miniscope v2a, b, c, d, e) of simple PC/USB oscilloscope/recorder: http://tomeko.net/miniscope_v2f/ It extends miniscope v2e with PGA (MCP6S21) offering same sampling frequency (480 ksps, 8 bit real time streaming to PC allowing continuous recording up to 512M samples) but 8 gain ranges and high input impedance. Estimated price is $6 […]
WiFi-based Weather Forecast and Clock
https://www.electronics-lab.com/wifi-based-weather-forecast-and-clock/
by soniktech.com: This project is a stopgap on my way to building a ground-up “Internet of Things” base design around the ESP8266 SoC WiFi solution. I started by taking a few nixie tubes I’ve had lying around from a past project, and connecting them to a Nixie Power supply I found on ebay. After making […]
Attiny45 EMF Sensor
https://www.electronics-lab.com/attiny45-emf-sensor/
by Khaleel123 @ instructables.com: This sensor is very sensitive and can pick up electrical signals from anything that uses power. It displays the amount of interference it picks up by sequentially lighting 4 led’s one after the other. I have tested it all around the house and its been kinda fun to see how different things […]

Dave checked out the Leica DVM6 3D microscope at the Electronex 2015 stand. It’s an $80000 microscope that can do automated 3D surface mapping and measurements of surfaces, down to sub 1 micron. EEVblog #796 – Leica DVM6 3D Microscope – [Link]
Transparent ESP8266 WiFi-to-Serial Bridge
https://www.electronics-lab.com/transparent-esp8266-wifi-to-serial-bridge/
jeelabs @ github.com has written a firmware for ESP8266 that enables it to talk to RS232 of your mcu via WiFi and also programm your mcu via WiFi. He writes: This firmware connects an attached micro-controller to the internet using a ESP8266 Wifi module. It implements a number of features: transparent bridge between Wifi and […]
Building our own backup server using the Raspberry PI
https://www.electronics-lab.com/building-our-own-backup-server-using-the-raspberry-pi/
by Michal Remias @ wpress.io: We’ve been always thinking about building our own backup server using the ARM solution of Raspberry PI. When we needed to manage approx. 25 WordPress web projects couple of months ago we did some experiments with MainWP on virtual server at DigitalOcean. To make the server a bit more reliable and […]
Bias generators with ultralow noise and ripple for sensitive circuits
https://www.electronics-lab.com/bias-generators-with-ultralow-noise-and-ripple-for-sensitive-circuits/
The LT®3095 generates two low-noise bias supplies from a common input voltage ranging from 3V to 20V. Each channel includes a fixed frequency, peak current-mode step-up switching regulator and a low-noise, singleresistor- programmable 50mA linear regulator. The linear regulator’s high power supply ripple rejection (PSRR) combined with its low-noise performance results in less than 100μVP-P […]

Simple Infrared Barrier
https://www.electronics-lab.com/simple-infrared-barrier/
by Maurizio @ dev.emcelettronica.com: Although a remote control is not so difficult to design and build, there is an even simpler option: the IR barrier. This consists of a constant IR signal permanently going from an emitter to a receiver, both of them being in two different places (a few meters apart). When an obstacle comes […]
