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...

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...

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...

The projects shown here is a 2 Digit 00-99 Seconds or 00-99 Minutes Countdown kitchen timer based on PIC16F1825 micro-controller. The timer is useful in various applications like Cooking, Sports, Industrial, Sleeping. On board switches provided to set the time and start, a jumper to...

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 -...

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....
