How To Select a Capacitor
https://www.electronics-lab.com/how-to-select-a-capacitor/
Sanket Gupta @ blog.octopart.com has written a capacitor select guide. The article goes through aluminum electrolytic capacitors, ceramic capacitors, Tantalum Capacitors, mica capacitors, film capacitors and Polymer Capacitors. In this blog, we will explain all the different types of capacitors, their merits and demerits, and popular applications. We have included some recommendations for commonly used capacitor series with […]
Programming an ATtiny with Arduino board
https://www.electronics-lab.com/programming-attiny-arduino-board/
This detailed tutorial shows how to program an ATtiny45, ATtiny85, ATtiny44 or ATtiny84 microcontroller using the Arduino software. The ATtiny45 or 85 is a great option for running simple Arduino programs: it’s small, cheap and relatively easy to use. It does, however, have some limitations relative to the ATmega328P on an Arduino Uno. There are […]
ATtiny85 Game Console
https://www.electronics-lab.com/attiny85-game-console/
webboggles.com has designed a SSD1306 OLED Screen based game kit using an ATtiny85 microcontroller. They also sell it as a kit to assemble it yourself. The new snap case has been updated to allow enough height for the screen header as well as a factory made CR2032 battery holder. The buttons have been concealed to […]
HTML5 Circuit Simulator

Iain Sharp build this port of online Circuit Simulator based on Paul Falstad’s simulator, however Sharp’s version is built using HTML5 and requires no plugin to run. Think of it like animated Fritzing circuits, with a slew of pre-built circuits and components available for tinkering with. HTML5 Circuit Simulator – [Link]

ATTiny85 board A First Look and review
https://www.electronics-lab.com/attiny85-board-first-look-review/
educ8s.tv wanted to take a look at this tiny board for a long time. It is very small size, it is low cost and it uses a different processor than the Arduino boards. It uses the ATTiny 85 microcontroller chip, which can operate at a frequency up to 20Mhz. It has 8Kb of flash memory, […]
How to Control a Reflow Oven with Raspberry Pi
https://www.electronics-lab.com/control-reflow-oven-raspberry-pi/
Here is a great Raspberry Pi based Reflow oven controller from “apollo-ng” on GitHub. You can edit your temperature curve on your browser and Rasberry Pi controls the solid state relays and fan. Turns a Raspberry Pi into a cheap, universal & web-enabled Reflow Oven Controller. Of course, since it is basically just a robot […]
Electricity Frequency Meter
https://www.electronics-lab.com/electricity-frequency-meter/
This project is about an accurate mains frequency meter that has a bar-graph displaying the relative deviation from nominal frequency. It can work with 50Hz and 60Hz systems. An article by Dieter Laues in the February 2012 issue of Elektor inspired me to get my soldering iron out. The article described how by measuring the […]
Arduino Remote Control Tutorial
https://www.electronics-lab.com/arduino-remote-control-tutorial/
Øyvind Nydal Dahl show us how to use an IR remote control with Arduino. For this purpose he connects a TSOP312 and an IR LED to Arduino and goes in detail on the sketches. In this tutorial I am going to show you exactly how to make an Arduino remote control. You can use this […]
BeagleBone Logic Analyzer
https://www.electronics-lab.com/beaglebone-logic-analyzer/
Make your own logic analyzer using BeagleBone board. Software is where the magic happens. There is a pre-made image for the BeagleBone with everything loaded and configured to use the BeagleLogic. It’s a recent image based on Debian instead of the older Armstrong builds. The nice thing is that it doesn’t flash the eMMC so […]
