This summer, my hackerspace LVL1 (in Louisville, Ky) got an awesome laser cutter http://fslaser.com/40w-deluxe-hobby-laser-engraver-and-cutter.  LVL1 is an awesome community of creative folks that like to build stuff.  You can always check out what we are up to at http://www.lvl1.org.  If you like instructables and making stuff, you should see if there is a hackerspace in […]

There are many electronic devices that use the SPI  bus, or Serial Peripheral Interface bus, for communications (e.g. various sensors, LCD displays, digital potentiometers, D/A and A/D converters, wireless transmitters and receivers, audio volume controls).  The devices receive data serially from a microcontroller using a 3-wire set-up that includes a chip select signal (usually titled […]

This instructable primarily shows how to control the charging voltage from a solar panel to an energy storage device (capacitors in this case). I showed how to construct the light previously http://www.instructables.com/id/Human-Powered-Light-from-my-book-Doable-Renewab/ Step 1: This solar panel can produce up to 18 volts, but my capacitor bank should never receive more than 15 volts.  I […]

I developed the camera trigger unit in order to synchronize various events and actions during free-flight experiments with hawkmoths in the wind tunnel described in a previous post. More specifically, the goal was to trigger multiple high-speed cameras and have LEDs that indicate the exact timing of electrical stimuli delivered via a miniature stimulus chip […]

This is an arduino controlled project and uses leds, jumper wires, and a breadboard. This is one of my first attempts on programming arduino and I am pleased with the outcome. I’m ten years old and I just started programming 2 weeks ago. Step 1: Parts Check Step 2: Placing the LEDs on the breadboard […]

While trying to create a circuit that detects whether water is flowing through a pipe by measuring the vibration with a piezoelectric sensor, just to see what happens I taped the sensor around my finger and – to my surprise – got values that were a very noise-free representation of my heart rate! This is […]

R.O.V.E.R. is an autonomous robot. He was built and designed as an interactive art installation specifically for the MAT EoYS 2013. He navigates the space with a heat array and bump sensors and interacts with attendees. When R.O.V.E.R. recognizes that a person is present he plays a song. If people are still visible and how […]

This is a third project in our chipKIT tutorial series and today we are going to construct a simple pulse rate meter using our Easy Pulse sensor with Digilent’s chipKIT Uno32 board. Digilent’s chipKIT Basic I/O shield is also used in this project for displaying the pulse waveform and the pulse rate. – See more at: http://embedded-lab.com/blog/?p=8183#sthash.lA1QV6E3.dpuf What […]

In this tool-assisted education video I show how to program an Arduino Atmega2560 board in C++11 to dump a ROM chip, such as a 386sx BIOS or a Famicom cartridge ROM. I also make a ZMODEM sender and a LED blinker in this video. Sorry about the bad dub / lipsync in the beginning. I […]

Stage combat is the art of theatrical violence.  Rather than resembling fencing, stage combat is choreographed like dance for aesthetic and theatrical effect as well as for safety.  Over years of choreographing and teaching others stage combat choreography, I realized that one of the most difficult aspects of teaching someone choreography is the necessity of […]
