CORE ROPE MEMORY MAKES ONE OF THE ODDEST LED FLASHERS WE’VE EVER SEEN

If you’ve heard of core rope memory, it will probably be in the context of vintage computing equipment such as Apollo-era NASA hardware. A string of magnetic cores and sense wires form a simple ROM arrangement, which though long-ago-superceded by semiconductor memory remains possible to recreate by the experimenter. It’s a path [Nicola Cimmino] has […]

Electromagnet Superhero Glove

Sensor – Transducer – Detector Project Ideas / By Ibrar Ayyub

For a class assignment, I needed to make something fabric-based which took an Arduino, some programming, and at least two inputs and outputs. After sketching a few different ideas, I hit on this one: an electromagnetic glove for MagnetoGirl. It sprang to life for me, because magnetism is an invisible force which can seem magical.

Arduino Is Slow – and How to Fix It!

Arduino LED Project Ideas / By Ibrar Ayyub

Arduino is slow? What? This instructable will show just how slow a part of Arduino is, and how to fix it. It’s true – more specifically, Arduino’s digitalWrite command takes a considerable amount of time. If you are just switching on a LED once or something, you won’t be able to notice it. However, I

KINETIC LAMP SHEDS LIGHT ON SCIENTIFIC PRINCIPLES

Arduino News / By Ibrar Ayyub

This thing right here might be the coolest desk toy since Newton’s Cradle. It’s [Stephen Co]’s latest installment in a line of mesmerizing, zodiac-themed art lamps that started with the water-dancing Aquarius. All at once, it demonstrates standing waves, persistence of vision, and the stroboscopic effect. And the best part? You can stick your finger in it.

Arduino LED Exploration

LED Projects / By Ibrar Ayyub

Arduino LED ExplorationMy program shows you all of the data on your Led from the first light to the normal operation light. From that data you can pick an RS that is good light, but lower in current. You must build the circuit to run my program. You must open a terminal window when you

LilyPad Arduino Painted Canvas With Music and Lights

Sound – Audio Projects / By Ibrar Ayyub

This is a project that I created for my Children and Technology class that I am taking in my Masters of Library Science Program. This was one of my first experiences with coding so this was a trial and error process but this instructable should outline my success throughout the process. My initial inspiration came

A POCKET QWERTY FOR ARDUINO AND MORE

Arduino News / By Ibrar Ayyub

If you want to add a keypad to your Arduino project, the options are pretty limited. There’s that red and blue 4×4 membrane we’ve all seen in password-protected door lock projects, and the phone layout version that does pretty much all the same tricks. Isn’t it time for a full Arduino-compatible keyboard? [ELECTRONOOBS] thinks so.

FORCE SENSITIVE RESISTOR TAKES THE PAIN OUT OF BED LEVELING

Arduino News / By Ibrar Ayyub

How do you know if your 3D printer bed is levelled? Oh, don’t worry – you’ll know. Without a level bed, filament won’t stick properly to the build surface and you’ll run into all sorts of other problems. Knowing how tricky it can be to get the bed just right, [Antzy] built a tool to help.

1Amp Constant Current LED Driver Shield for Arduino Nano

Electronics News Updates / By Ibrar Ayyub

1A Constant current LED driver shield for Arduino Nano has been designed for verity of LED related applications. The shield provides accurate LED current sink to regulate LED current in a string of LEDs or single LED. The LED current is mirrored from the current flowing from the RSET Preset PR1. On board 1W LED

SUNTRACKER OPTIMIZES SOLAR PANELS WHILE VISUALIZING SUN’S PATH

Arduino News / By Ibrar Ayyub

If you have solar panels, you want soak up as much sunshine as you can to get your money’s worth. If you don’t have space for a lot of panels, the next best thing is repositioning the panels to catch the most rays. For his entry into the Hackaday Prize, [Frank] built a gorgeous solar tracker
