“In this project, I converted an old toy R/C car from the thrift-store into a bluetooth controlled robot. The conversion requires an Arduino, an L298N dual 2-amp motor-controller, and a bluetooth serial adapter.”

“Our project is a space dogfighting video game where two players attempt to destroy each other using a variety of ships and weapons. The battlefield is a 128×100 pixel area on a TV, and a small planet resides in the middle, exerting gravitational forces on the ships and inviting them to certain death. The input devices are Sega Genesis controllers, which were chosen because of their signal simplicity and sleek look.”

Last week, we released the first lesson of the first PyroEDU course: An Introduction To Modern Electronics. This week we’re really getting started with the course content with a lesson on Electricity. This lesson explains what electricity is in plain english, how we describe it mathematically and also how you can see the effect electricity has on the devices you use everyday.

“In the days of yore amateurs used to hack a calculator to simulate a keypress to help them count the coil windings. Calculators are relatively rare and harder to tweak these days. There’s an assortment of other awesome tools around however. For example, a Cyclone II development kit.”

“Just about any physical signal or measurement in the world can be converted into a fluctuating voltage, an analog signal. Most laptops have a built-in microphone, so if you can convert your voltage into an audible signal, you can use the microphone to digitize it. Once it is in digital form, you can then process the signal with any programming language. Here we’ll use Mathematica.”

“The goal was to build an adapter to make possible the use of GC controller on N64 system since the N64 controller analog is rather bad. Another goal was to make a rather complete reverse engineering of both N64 and NGC controller protocol…So Cube64-DX is Cube64 with bug fix and new features!”
