[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 […]

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

Do you want to control your TV and several other gadgets that are IR controlled? Ya but my phone doesn’t support it because it doesn’t have an IR blaster.Don’t worry here a gadget that gives IR control to any phone and the thing it needs is bluetooth!! YES!! bluetooth!! The gadget also increases the range

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)

In this project I will show you how to combine a SIM5320 3G module with an Arduino and a piezoelectric transducer as a shock sensor in order to create a security tracking system that will send you the location of your precious vehicle via SMS when it is moved around without you knowing it. Let’s get

Build a convincing artificial fire effect for the holiday season using NeoPixel LEDs, an Arduino UNO, and a cool mist module. Story This is a project I’ve had on the backburner for almost exactly 1 calendar year. The seed was planted when I toured the Harry Potter Studios last year and saw a fake fireplace

The typical parallel LCD used with an Arduino (16×2 or 20×4) has 16 pins. Only 6 I/O pins are required on the Arduino, but what if you could get that down to two I/O pins, and still have those pins available for other devices? The I2C interface is on pins A4 and A5 of the

This is, as the title says, an Arduino-based robotics platform, with its own library. The “standard” model comes with two back motors, two omni-wheels in the front, and a distance sensor mounted on the front. It also has breadboard space on top for adding whatever you want. It is intended to be autonomous, but one
