A CHROME EXTENSION FOR CONFIGURING RGB LEDS

Like pretty much all of us, [Andy Schwarz] loves RGB LEDs. Specifically he likes to put them on RC vehicles, such as navigation lights on airplanes or flashers and headlights on cars. He found himself often rewriting very similar Arduino code for each one of these installations, and eventually decided he could save himself (and all the other hackers in the world) some time by creating a customizable Arduino ...

Contactless Controlled Automatic Wardrobe LED Light

Contact-less controlled automatic wardrobe light turns on the LED when you open the wardrobe door. Τhe project is based on Hall effect IC including LED driver and tiny magnet. Board doesn’t require any mechanical switch. When magnet is close to the board, LED is off, when you open the wardrobe door magnet goes far from hall IC and its turn on the LED, the IC also has special features like soft start and sof ...

THIS GPS SPEEDOMETER HANGS OFF YOUR HANDLEBARS

If you can ride a bike with no handlebars, no handlebars, no handlebars, you can do just about anything. You can take apart a remote control, and you can almost put it back together. You can listen in on a two meter repeater and you can build a GPS module speedometer. That’s what [Jeremy Cook] did with just a few parts, a little 3D design, and some handy zip ties to hold it onto the handlebars, the handleba ...

A HIGH-SPEED SLIDE SCANNER BUILD

Photographic slides were popular in the middle part of the 20th century, but are long forgotten now. If you’ve found a handful in a dusty attic, you might consider sending them away to be digitized professionally, or using a flatbed scanner at home. [Bryan Howard] found himself with over 200,000 slides, however, so that just wouldn’t do. Instead, he endeavored to build an automated scanner of his own.  Like ...

A FPGA controlled RGB LED MATRIX for Incredible Effects

In this post you will find  the description of a graphic display that uses a modular solution based on dot matrix blocks (in which each dot is a RGB LED), that are driven – via a specific bus – by a very powerful control board, that is entirely programmable and capable of managing even very fast animations, thanks to the FPGA it is supplied with. Yes, the key factor is the Spartan-6 Field Programmable Gate ...

FIZZLE LOOP SYNTH DOES IT WITH 555 TIMERS

For every project that uses an Arduino to make soup or an ESP8266 to hash bitcoin, there’s always someone out there uttering the same old refrain. I could have done it with a 555. More often than not, this is true, even if it is tangential to the discussion being had. In this case however, such a statement is moot. [lonesoulsurfer] has built the Fizzle Loop Synth, featuring not one, but three triple-nickel ...

How to build a plant monitor with Arduino

As a preview of his latest book, Arduino Project Handbook: 25 Practical Projects to Get You Started, Mark Geddes takes us through the project to create a simple plant monitor. In this project I’ll introduce a new type of analog sensor that detects moisture levels. You’ll set up a light and sound alarm system (an inexpensive piezo buzzer) to tell you when your plant needs watering See also: How to build a la ...

A Guide to Metal Core PCBs by PCBGOGO

Introduction: The use of LED based electronics has significantly increased in the past few years. They have proven to be more efficient and nearly 5 times cheaper than normal incandescent units. But with their use came one downside: heat. Some devices tend to use a number of LEDs that remain on for a long period of time and so can overheat. The LEDs are usually mounted on PCBs and can therefore cause signif ...
