"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...

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...

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...

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...

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 -...
