If you like the retro look of old Soviet space hardware, then this replica of the model 774H Soyuz digital clock by [David Whitty] might be the perfect accessory for your desk. Forgoing the original stack of ten jam-packed circuit boards, [David] used an Arduino, a GPS receiver, and a handful of other common parts to create […]

In this project, you will turn the Arduino into a thermometer! Use a temperature sensor to measure your skin temperature, and register the output with three LEDs. Even though the Arduino is a digital tool, it can interpret signals from an analog input, like the TMP36 temperature sensor, using the built in Analog-to-Digital (ADC) converter, […]

In this project I will show you how I combined an Arduino Nano, a current sensor, an LCD, a rotary encoder and a couple of other complementary components in order to create an adjustable constant load. It features a constant current and power mode and can handle a maximum of 30V and 20A if your […]

It used to be that building your own watch was either a big project or it meant that you didn’t really care about how something looked on your wrist. But now with modern parts and construction techniques, a good-looking smart watch isn’t out of reach of the home shop. But if you don’t want to […]

Don’t know about you, but over the last year or so, we have gone from spending ten or twelve hours a day at this computer to upwards of sixteen or eighteen. Fortunately there’s a window behind the monitor for taking those 20/20/20 breaks that are supposed to prevent eye strain, but it’s so hard to […]

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 […]

If you have kids, you are likely facing the same issues as we did with the Lego sets you bought for them. They assemble and play with them but after a while the sets transform into a single pile of bricks. The kids grow up and you don’t know what to do with this pile. […]

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, and we’ll build on those skills in this lesson. Ultrasonic […]

Bored of keeping track of countless locks and their keys? How about using your own fingerprint to unlock each and every safe in your house, just like your Smartphone? Sounds cool, right? Let’s make an electronic Fingerprint locker that will keep all your secrets a secret from your enemies. And not only one, but up […]

Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with […]
