It will enable you to pull in weaker and more distant stations. Local strong stations will have extremely loud volume.”]]> http://www.pyroelectro.com/2013/05/19/poor-mans-single-transistor-audio-amp/feed/ 0 http://www.pyroelectro.com/2013/05/19/poor-mans-single-transistor-audio-amp/ Junk + Arduino = Robot #2 http://feedproxy.google.com/~r/pyroelectro/~3/y2L2FrHdIXo/ http://www.pyroelectro.com/2013/05/18/junk-arduino-robot-2/#comments Sat, 18 May 2013 19:30:30 +0000 Chris http://www.pyroelectro.com/?p=10791 “This was the second robot I made for collective motion research purposes. As you can see, it is vastly simpler, cheaper and easier to build. Of course it doesn’t have nearly as many features or as much potential as robot 1, but I think it is much better for what I’m trying to do. Here’s a picture of the prototype without the battery.”]]> http://www.pyroelectro.com/2013/05/18/junk-arduino-robot-2/feed/ 0 http://www.pyroelectro.com/2013/05/18/junk-arduino-robot-2/ Eternal Free-Swinging Pendulum http://feedproxy.google.com/~r/pyroelectro/~3/XgaugI55vAM/ http://www.pyroelectro.com/2013/05/17/eternal-free-swinging-pendulum/#comments Fri, 17 May 2013 23:18:44 +0000 Chris http://www.pyroelectro.com/?p=10787 “This is the dedicated page about our first kit project – Eternal Free-swinging Pendulum, also known as Omni Pendulum. It’s a long and detailed story…”]]> http://www.pyroelectro.com/2013/05/17/eternal-free-swinging-pendulum/feed/ 0 http://www.pyroelectro.com/2013/05/17/eternal-free-swinging-pendulum/ Design A 4-Bit Counter http://feedproxy.google.com/~r/pyroelectro/~3/7qW50BltFns/ http://www.pyroelectro.com/2013/05/16/design-a-4-bit-counter/#comments Thu, 16 May 2013 18:30:49 +0000 Chris http://www.pyroelectro.com/?p=10782 Design A 4-Bit Binary Counter. Here’s a quick intro of what this PyroEDU lesson is all about:

A great strength of digital circuitry is that the clock can act as a timer or counter with appropriate flip-flop circuitry in place. In this lesson, using some LEDs, we will learn how to build a 4-bit binary counter that uses the clock input to tell our circuit to increment a counter with every clock period.

The original idea came from one evening I went out with my son to the park near my home in Korat. The park has a nice walking way for people to exercise. I was wondering how long the distance is?”]]> http://www.pyroelectro.com/2013/05/15/electronic-distance-meter/feed/ 0 http://www.pyroelectro.com/2013/05/15/electronic-distance-meter/ Spoke Ink – Persistance of Vision for your Bike http://feedproxy.google.com/~r/pyroelectro/~3/NnIejDzijIA/ http://www.pyroelectro.com/2013/05/14/spoke-ink-persistance-of-vision-for-your-bike/#comments Tue, 14 May 2013 22:26:25 +0000 Chris http://www.pyroelectro.com/?p=10776 “Take your MSP430 for a spin with Spoke Ink! Spoke Ink is a booster pack that attaches to the spokes of your bicycle wheel. Using an array of 32 RGB LEDs and a magnetic sensor, this booster pack projects a bright, upright image right from the spokes of your wheel. Using our software, you can create this image from any bitmap.”]]> http://www.pyroelectro.com/2013/05/14/spoke-ink-persistance-of-vision-for-your-bike/feed/ 0 http://www.pyroelectro.com/2013/05/14/spoke-ink-persistance-of-vision-for-your-bike/ 5^3 LED CUBE Controller http://feedproxy.google.com/~r/pyroelectro/~3/OUWHQDb3FL4/ http://www.pyroelectro.com/2013/05/13/53-led-cube-controller/#comments Mon, 13 May 2013 23:07:08 +0000 Chris http://www.pyroelectro.com/?p=10773 “The cube described on this page uses a 5 x 5 x 5 matrix of single colour LEDs. This is a good size to experiment with as the number of LEDs required at 125 keeps the cost down, doesn’t take too long to assemble and just fits onto a eurocard sized PCB. The power requirement is under 1 amp and the use of just one colour keeps both the hardware construction and control software fairly simple.”]]> http://www.pyroelectro.com/2013/05/13/53-led-cube-controller/feed/ 0 http://www.pyroelectro.com/2013/05/13/53-led-cube-controller/ Brute Force Attack A BIOS With Arduino http://feedproxy.google.com/~r/pyroelectro/~3/OwxfUHYzON0/ http://www.pyroelectro.com/2013/05/12/brute-force-attack-a-bios-with-arduino/#comments Mon, 13 May 2013 04:19:13 +0000 Chris http://www.pyroelectro.com/?p=10770 “The goal of this experiment is to convert the Arduino board into an USB keyboard plus a VGA sniffer to crack the password of a standard BIOS using the brute force attack method. There are no advantages in using this method, in fact this can be very slow and you may never find the password at all, but as always we do it for fun.”]]> http://www.pyroelectro.com/2013/05/12/brute-force-attack-a-bios-with-arduino/feed/ 0 http://www.pyroelectro.com/2013/05/12/brute-force-attack-a-bios-with-arduino/ Sensing Squeeze http://feedproxy.google.com/~r/pyroelectro/~3/z87oGwvVZjc/ http://www.pyroelectro.com/2013/05/11/sensing-squeeze/#comments Sun, 12 May 2013 04:31:14 +0000 Chris http://www.pyroelectro.com/?p=10767 “I’m researching squeeze sensing as a mode of tactile interface.
