[CuriousMarc] is nothing if not curious. Finding some old TI timekeeping chips to reverse engineer, he set out to make a clock using old-fashioned “bubble LEDs.” You can see the …read more Continue reading LED Bubbles from the 1970s Tell the Time
While most autonomous vehicles are meant to travel over the highway, John Deere’s new 8R tractor shown at the 2022 Consumer Electronics Show will likely only traverse fields and it …read more Continue reading This John Deere Tractor Doesn’t Need a Driver
[Zekfoo] decided to honor the Game Boy Advance’s 20th birthday by redesigning it at the circuit level to give it a more modern twist. To quote the project readme: I …read more Continue reading Modernizing The Game Boy Advance
Measuring resistance doesn’t seem to be a big deal. Put your meter leads across two wires or terminals and read the value, right? Most of the time that is good …read more Continue reading How Many Wires Do You Need to Measure a Resistor?
If you are like [The Science Asylum], you might wonder how a capacitor can work since, at their core, they are nothing more than a gap filled with air or …read more Continue reading How Do Capacitors Work?
[G3OJV] knows the pain of trying to operate a ham radio transmitter on a small lot. His recent video shows how to put up a workable basic HF antenna in …read more Continue reading Ham Antenna Fits Almost Anywhere
Although the widespread use of 3D printers has made things like linear bearings and leadscrews more common, you still can’t run down to your local big-box hardware store and get …read more Continue reading Servo Plotter Needs Nothing Exotic
In an interesting post on Inverse, [Sarah Wells] does a deep dive into something you probably don’t think about very often: the blinking cursor. You’d assume there wasn’t much to …read more Continue reading Blinking Cursor Turns 54, Hardly Anyone Notices
In an ideal world, your FDM 3D printer’s bed would be perfectly parallel with the print head’s plane of movement. We usually say that means the bed is “level”, but …read more Continue reading 3D Printering: One Bed Level to Rule Them All
I was rebuilding one of my 3D printers — again — and decided I needed a display upgrade. A color screen is nice, but there are some limitations. I also …read more Continue reading TFT35 Dual Mode 3D Print Control – Hands On
