"This project started life a long time ago, with the intention to build an iPod clone, back when personal MP3 players were an expensive luxury and long before you could buy them from China on ebay for less than a light bulb. "

This week we continue with our new course: An Introduction To Sensors and begin to explore the world of Magnetic Sensors. Here is a quick overview of what we will cover in this lesson:

Magnetic fields may be invisible but they are all around us with different strengths. In this lesson we’ll see how a hall effect sensor can be used to detect a magnetic field and be used as a magnetic motor encoder.

"As an exercise to teach myself a little bit more real-time computer vision/robotics, I wanted to see if I could get a computer to autonomously play certain console video games. Video games are nice because they can provide a relatively decent simulation of a 3D environment, emphasize demand for real-time vision processing, I don’t have to go out in the field to run a test, and there is no penalty for screwing up."

"Jamison wrapped a second coil and we hooked it up to a green LED. Connect the power, move the coils close together. First light! Yes!! Now it was time to improve Jamison’s project. We tried a full-wave rectifier to increase the LED’s brightness, with not a large (if any) effect. We built a two-stage Cockcroft-Walton generator, with much better success."

"For some, there’s the step sequencer you dream of. Maybe it has a massive array of buttons for patterns, capable of spreading musical ideas across a lit grid. Maybe every last rhythm is visible, maybe it juggles layers and patterns with ease. This guy just went and built what he wanted."

This week we continue with out new course: An Introduction To Sensors and begin to explore the world of Motion Sensors . Here is a quick overview of what we will cover in this lesson:

Motion detection is vital for most security systems and the PIR motion sensor is a popular choice in that area. In this lesson we will learn how the PIR motion sensor works and how we can use it to set off an alarm when motion is detected.

"This animatronic plant was originally created for a local production of Little Shop of Horrors. I ‘repurposed’ it for a local library’s summer reading program in 2008. The narration was recorded using Sound Forge and the soundtrack was produced in Acid. All was done in house at Sleeping Dragon Studios, Ltd."

"In continuation to my previous post, I will start discussing how I solved the wireless distribution at my church in an economical way."

"The display consists of 7 LEDs in a vertical row. By moving them fast enough back and forth over each other, I can display a message which appears to be generated by a 7*n matrix of LEDs and not a single column of LEDs."
