“pinko” build a high resolution chronograph which has some great features. Check it out: This is a project is for chronograph that was purposely build for a good friend of mine to be used for accurate measuring of high speed processes. I am using two timers and the chronograph has three inputs, as depicted on […]

5V @ 2A Step Down Converter using TPS54202


https://www.electronics-lab.com/5v-2a-step-converter-using-tps54202/

The circuit shown here is a step down converter which can convert an input voltage varying from 8V to 28V to 5V. The circuit is based on TPS54202, which is a 2A synchronous buck converter. This IC has several features such as over-voltage protection and peak current mode control. Features Input(V): 8V DC to 28V […]

A custom 12V powerbank for Cube i7 Stylus from Muxtronics: Why would anyone even try to build a power bank – i.e. an external battery for charging mobile devices – these days? These things are commodity, it’s impossible to compete. Right? Well, that is until you find out that the type of power bank for your […]

Tiny CW Capacitive Touch Paddle

Edgar implemented capacitive touch sensing using an ATTiny4 to create a touch paddle for Morse code: Like many no-code operators, after being on the air for a while, I developed an interest and appreciation for Morse Code [..] I purchased a cheap paddle, but I found the clicking noise a little bit annoying. Tiny CW Capacitive Touch Paddle […]

ASUS Tinker Board Competing Raspberry Pi


https://www.electronics-lab.com/asus-tinker-board-raspberry-pi-new-competitor/

Raspberry Pi has been the household name for many years now, and many other companies have tried to replace it with their offering, but no one sussed to replace Raspberry Pi by performance and low-cost. Though, that might change as ASUS are entering the arena with their 90MB0QY1-M0EAY0 Tinker Board, which have better components across […]

TINY LOAD CELL AMPLIFIER


https://www.electronics-lab.com/tiny-load-cell-amplifier/

pinko @ blog.exrockets.com wanted to test some cheap load cells so he decided to build his own load cell amplifier. He writes: Both IA are Rail-to-Rail, single or dual power supply instrumentation amplifiers, however with different standard pin-outs. The gain is set by RG. RR1 and RR2 and CR form a voltage divider that could […]

It’s possible – there are a lot of fakes out there. Maybe you bought a counterfeit Arduino. Was it priced lower that normal? Is it missing the small details that make it a genuine Arduino board? Watch the video to find out if your Arduino is real or fake. Real vs Fake Arduino Test – […]

DIY an Arduino-Controlled AM/FM/SW Radio


https://www.electronics-lab.com/diy-arduino-controlled-amfmsw-radio/

Combine the Si4844-A10 analog-tuned radio receiver with an Arduino to make a full-featured multiband radio. The idea of a single chip radio is intriguing. The prospect is especially interesting to me because, frankly, I envy the analog skills I associate with building a radio receiver. When I browsed the circuit literature in the area, I […]
