Op Amp PID Controller Design

February 2, 2012 by Chris
“We've all heard about the wonders of the PID controller, bringing a system's output - temperature, velocity, light - to its desired set point quickly and accurately. But now, your boss says okay, design one for us. Although there's a number of ways to do it, the circuit above nicely separates the three terms into three individual op amp circuits. We'll build it in SPICE, test each term and finally place it inside a motor speed controller for you to tune.”

illucia: a codebending instrument

June 23, 2011 by Chris
"Codebending is the exploration of software with 'patch points.' Patch points expose the inner workings of computer programs, and allow for atypical connections between things like games, music making software, office suites, etc." This article explains the more intricate details of artistic electronics through a process called codebending with an instrument that looks like it came straight out of google labs.

Pure Breadboarded TTL Clock

June 20, 2011 by Chris
74xx TTL logic chips are widely available and cheap. Breadboards are built so that they fit perfectly , however the TTL clock created here shows you just how much can be done on them. This article shows you what it takes to create a TTL clock on breadboards with only jumper wire and TTL chips. Hardware schematics and demo videos are included.

10 Amp H-Bridge For Motor Control

May 20, 2011 by Chris
Today's PyroElectro tutorial shows you how to build your own 10A DC motor controller on a PCB. The core design is kept simple so it is a great introductory project for hobbyists, while also shedding light on the basic method used for DC motor control. The parts cost less than $15 so why not give it a shot?

Make A Jacobs Ladder

April 20, 2011 by Chris
An electrified jacob's ladder is a cool thing to see in action. Its high voltage nature, like the tesla coil, allows you to see raw electricity at kilo-volts. This article explains and shows you how to make a small scale jacob's ladder, with some rather unique parts.

Analog Mini Pendulum Robot

April 4, 2011 by Chris
Here's a cool little balancing robot that is purely analog. The parts required to build it are minimal and the fact that it works to me is simply amazing. The write-up is an instructable with all the details needed to make your own.

The R.I.O.T. Wheel

March 15, 2011 by Chris
Self balancing two wheeled segways be damned...the riot wheel puts them all to shame. This entire website is dedicated to explaining what the R.I.O.T. wheel is and how it was built. If this looks like something crazy enough for you, then read further.

Magnetic Levitation

March 5, 2011 by Chris
With proper electronic control, stable magnetic levitation of objects is actually quite possible. This project does just that too. Using only a handful of electric parts and an electromagnetic, levitation goes from black magic to reality.

IR Remote Control Tester Circuit

February 28, 2011 by Chris
Today's project gave me a quick laugh because it's short, sweet and to the point. Use two amplifiers and an IR receiver to build a simple IR remote control tester. When you press any of the buttons on the remote the speaker will play a tone depending on the button's command sequence.

Infrared IR Receiver

February 15, 2011 by Chris
Today's PyroElectro Tutorial shows how infrared remote controls work and guides you through the process of building an infrared IR receiver. The receiver decodes the infrared commands sent to it by a remote control, and displays them on an LCD for verification.
