Electronics hobbyists, engineers and developers looking for an automatic way to create KiCAD schematics may be interested in your project created by Nick Bild, capable of analyzing your physical breadboard and automatically generating a KiCAD schematic. Although it is worth mentioning that the script is have some limitations such as many ICs either don’t have internal continuity

[Lee Adamson] is no stranger to classic computers. He recently picked up a Heathkit H11A which, as you might remember, is actually a PDP-11 from DEC. Well, technically, it is an LSI-11 but still. Like a proper LSI-11, the computer uses the DEC QBus. Unlike a lot of computers of its day, the H11 didn’t have a

Controlling your computer with a wave of the hand seems like something from science fiction, and for good reason. From Minority Report to Iron Man, we’ve seen plenty of famous actors controlling their high-tech computer systems by wildly gesticulating in the air. Meanwhile, we’re all stuck using keyboards and mice like a bunch of chumps. But it doesn’t

It’s one thing to have an idea (especially a hardware-based idea) and it’s another thing to bring it to life. Rapid Prototyping using tools like 3D Printer has opened a lot of opportunities for the everyday makers, hardware enthusiasts, and hackers. For the person looking to build that next cool thing, maybe a PoV (Persistence of Vision)

Normally, when a project calls for addressable LEDs, we just throw a strip of WS2812s and an Arduino together, cobble together some code from the examples in the FastLED library, and call it a day. We don’t put much thought into what’s going on under the hood, unless and until we run into an LED project

Want to display a PNG file on a display attached to an Arduino or other microcontroller board? You’ll want to look at [Larry Bank]’s PNGdec, the Arduino-friendly PNG decoder library which makes it much easier to work with PNG files on your chosen microcontroller. The PNG image format supports useful features like lossless compression, and was generally

In this instructable, I will show you how to build a trampoline that changes colors whenever you jump on it! Step 1: The Things You Need Materials: 3 rolls of wire, different colors, the thinner the better Solder, the thinner the better – I had thick solder wires in the beginning, and it melted so

Traditionally, a forum full of technical users trying integrate their own hardware into a game system for the purposes of gaining unfettered access to its entire software library was the kind of thing that would keep engineers at Sony and Nintendo up at night. The development and proliferation of so called “mod chips” were an

For the last month or so I’ve been working on a project involving a NeoPixel, I chose to use a NeoPixel instead of the usual RGB LED strip because I felt that the individual addressable LEDs would be easier to work and create better effects. While this is true I did not take into account the learning curb
