Walking a dog in the dark comes with the safety risk of motorists who don’t see you walking, we’ve had a few close shaves with drivers turning quickly into or backing out of driveways or when crossing road intersections. So why not illuminate your favorite Doggo with a rainbow of colors to get motorists attention […]

I´ve been looking into LED Cubes and noticed that most of them were either to complicated or to expensive. After looking at a lot of different cubes, I finally decided that my LED Cube should be: easy and simple to build affordable very stylish and extravagant After having build multiple Arduino LED Cubes, I can

For our SIDE project, a year long project that we do for Ms. Berbawy’s Principles of Engineering class, we decided to make a stroboscopic fountain. The stroboscopic effect, pioneered by Harold Edgerton, makes objects appear as though they are moving in slow motion. How does this work? A strobe light is flashed at the same

As I was finalizing design decisions for an upcoming ESP32 WiFi Kit 32 based project requiring three button input, one noticeable problem was that the WiFi Kit 32 does not possess a single mechanical pushbutton, yet alone three mechanical buttons, for input. However, the WiFi Kit 32 does have plenty of capacitive touch inputs, so

I wanted to create a digital version of the Magic 8 Ball… The body of this is 3D printed and the display has been changed from an polyhedron in blue dye to a small OLED controlled by a random number generator programmed into an Arduino NANO. Then I went on a bit of a tangent

In optical microscopes, there is a fundamental trade-off between field-of-view and resolution: the finer the detail, the smaller the region imaged by the microscope. One way to overcome this limitation is to translate the sample and acquire images over a larger field-of-view. The basic idea is to stitch together many high resolution images to form

This is v1.0 of the PasswordPump, a USB device that manages credentials for up to 254 accounts. Credentials (account names, usernames and passwords) are stored ONLY on the device itself, on two removable EEprom chips using military grade encryption (AES-128). They are not stored in the cloud or in a file on your computer where
PasswordPump Passwords Manager Continue Reading
In this DIY guide I will show you how to make your own wireless weather station! My communication protocol will allow you to have up to 10 sensor stations in your wireless network, but you can change and extend it up to 254 stations! The RF technology and the module that we used will allow
Arduino Based Wireless (RF) Weather Station Network Continue Reading
Time for a fun-filled, easy-peasy Japan-easy to make a project! Today, we’re going to show you how to make an LED POV Display. POV, an acronym for the persistence of vision, is a kind of optical illusion in which a visual image seems to persist even when the light from it ceases to enter our
Persistence of Vision (PoV) Display Using Arduino Continue Reading
