When electronics release the Magic Smoke, more often than not it’s a fairly sedate event. Something overheats, the packaging gets hot enough to emit that characteristic and unmistakable odor, and …read more Continue reading Quick and Very Dirty Repair Gets Smoked PLC Back in the Game
We’ve always been fascinated by things that perform complex electronic functions merely by virtue of their shapes. Waveguides come to mind, but so do active elements like filters made from …read more Continue reading Making PCB Strip Filter Design Easy to Understand
Submitting a new device for electromagnetic compatibility (EMC) testing seems a little like showing up for the final exam after skipping all the lectures. You might get lucky and pass, …read more Continue reading Homebrew TEM Cell Lets You EMC Test Your Own Devices
This edition’s community build comes from the Yes They Could, But Should They Have? file. Well, I ultimately say yes, this is intriguing. Redditor [dj_edit] looked at the venerable Model …read more Continue reading Keebin’ with Kristina: the One With the Music Typewriter
[Noteolvides] creates the CubeTouch, a cube made of six PCBs soldered together that creates a functional and interactive piece of art through its inlaid LEDs and capacitive touch sensors. The …read more Continue reading Keyboard Shortcuts at the Touch of a Planetary Cube
We all make mistakes, and there’s no shame in having to bodge a printed circuit board to fix a mistake. Most of us are content with cutting a trace or …read more Continue reading PCB Microsurgery Puts the Bodges Inside the Board
Shutter shades were cool once upon a time, but if you really want to stand out, it’s hard to go past aggressively bright LEDs right in the middle of your face. A great way to achieve that is by building …read more
With how cheap and how fast custom PCBs have gotten, it almost doesn’t make sense to roll your own anymore, especially when you factor in the messy etching steps and the less than stellar results. That’s not the only way to create a PCB, of course, and if you happen …read more
Yes, circuit sculptures are amazing. But the patience and skill required puts most of the designs we’ve seen fairly far out of reach of the average beginner. We totally understand — not everyone finds fun in fiddly, structural soldering.
[Hari Wiguna] was captivated by the LED ball that [Jiří Praus] …read more
If you design printed circuit boards, then you will have also redesigned printed circuit boards. Nobody gets it right the first time, every time. Sometimes you can solder a scrap of 30gauge wire, flip a component 180°, or make a TO-92 transistor do that little pirouette thing where the …read more
