In Froggy World, the amusement park for adventurous plastic frogs, it became necessary to to move the frog from a train car back to the catapult.  Because I couldn’t know whether the frog would be upright or sideways–and in what orientation–the gripper was a challenge. I read about the “coffee gripper” developed at Cornell and […]

This is my homemade Dual H-Bridge using the IC L298N. For control DC motors or step Motors ao other purposes just like you need. Breakout L298N.ppt1 MB Step 1: Hardware and Materials This is the basic schematic. It works perfectly. A more advanced schematic and board for eagle cad, you can download from the link […]

Bubble Wall | Breathing Wall Panel System Interactive, Inflatable, Playable Wall Brief Project Description This was an artistic piece installed for a digital fabrication show at the University of South Florida School of Architecture and Community Design. While this brief is specific to this panel, my hope is that the ideas presented here, will inspire […]

Let’s put together a pixel strip with an HL1606, an Arduino UNO and the Spectrum Shield to build a seven bands “large” Spectrum Analyzer of simple construction. The Strip used uses the HL1606 controller to allow direct management of each of the LEDs. The chip runs two RGB groups and has 4-pin for input/output. The […]

Using an Arduino microcontroller, an Adafruit motor shield, and a Wii Nunchuk, you can create a intuitive, programmable, model train controller to run your layout.  Amaze your friends.  Entertain your kids.  Not quite DC, not quite DCC.  You’re headed for the hacker lands of PWM (pulse-width modulation). Why do this? – Pulse-width modulation allows smooth […]

Music party is a new way to listen to music with others. By tapping an RFID/NFC device that is synced to a Facebook account on an Arduino RFID reader shield and sending that unique ID to Music Party server using the Arduino WiFly shield, we can automatically listen to the favorite music of everyone who […]

Working with the interaction design team, a bunch of us at Teague have been tinkering with measuring water, analyzing usage data in realtime to affect behaviors, and storing it to see patterns over time. At the heart of the exploration was a need to cheaply measure water from the tap.  Water meters vary quite drastically in price […]

Connecting the LCD The first step is to wire up the LCD. The HD44780 has 16 pins: Pin 1 – Vss Pin 2 – Vdd Pin 3 – Vo Pin 4 – RS Pin 5 – R/W Pin 6 – E Pin 7 – DB0 Pin 8 – DB1 Pin 9 – DB2 Pin 10 […]

Tools: 1.  Drill 2.  3/4″ and 1/4″ drill bits Step 1: Instructabot Platform I used a piece of wood 6″ x 12″ x 0.5 Step 2: Electronics Now for the electronics… The brain of the robot is an Arduino UNO which reads the accelerometer and gives commands to the motor controller which in turn powers […]

This instructable is a guide for setting up an automated gardening system using an arduino and other cheap electronic parts.  It allows sustainable gardening by using sensors to determine soil moisture, as well as a webscraper to determine future weather.  It uses this information to save water by only using the requisite amount.   Requirements for this project include experience soldering, […]
