"Spin uses Persistence of Vision to create the illusion of a cylindrical digital display (computer screen), 12 feet tall and 12 feet in diameter. Vertical columns of multi-color LED (light emitting diode) clusters spin around a vertical axis at 90 revolutions per minute. At a radius of 6 feet, they move at 41 miles per hour."

"This is a simple and cheap homemade laser driver. The LM317 is capable of up to 1.5A, which makes it possible to use it for >1000mW laser diodes. All parts together cost me around 2€. (~2.5$)"

This week we’re diving into tilt sensors in our new PyroEDU course: An Introduction To Sensors. In this lesson we’ll look at everything there is to know about Tilt Sensors and perform a simple experiment to give you a hands-on feel for how they work. Here’s a quick intro of what this PyroEDU lesson is all about:

The mechanical tilt sensor is one of the most basic types of sensors available. In this lesson we will learn how the tilt sensor uses some conductive balls to detect when the sensor has passed ± 90° of tilt.

"Chlonos is an electronic gadget with a brain, a display, some sensors and a voice. It’s something interesting to put on your wall. It can measure temperature and light, it keeps track of the time and will tell you about it all."

"A ballistic chronograph is used to detect the speed of a projectile shot through a sensor port. The simplest type of chronograph design is based on finding the average speed of the projectile between two ports. This is as easy as dividing the distance between the two sensor ports with time taken to travel between the ports."

"Essentially, the RC car will follow a path drawn by the user on the touch screen as it is drawn in real time. Speed and direction of the car was extrapolated from the user drawn path and sent to the car through radio frequency transmission. We utilized a touch screen taken from an old Palm Pilot, the chassis of an old RC car (including the motors), and a transmitter receiver pair."

"PCB Rax is an easy to use, versatile circuit board holder for repair, prototyping, and assembly that can hold nearly any shape of circuit board. Sure there are other circuit board holders on the market, but they don’t hold odd shaped boards, and they don’t allow you to easily move them around. "

"This project falls purely into the ‘because I can!’ category – I was poking around the internet one day looking for a Cray emulator and came up dry, so I decided to do something about it. Luckily, the Cray-1 hardware reference manual turned out to be useful enough that implementing most of this was pretty straightforward. The Cray-1 is one of those iconic machines that just makes you say ‘Now that‘s a super computer!’ "
