Kit-of-No-Parts. I wish I had made one of these.

Kit-of-No-Parts

But no, not yet. Inspired by the work of Arthur Ganson and other kinetic artists, this post features some mechanical gears assembled and sculpted from various materials such as wire and cardboard. In contrast to casting traces by applying the cast material selectively to a flat surface, molded circuitry is cast into a mold. I’m interested in being able to cast both flexible and firm conductive materials in combination with common casting materials such as silicone and epoxy. This post describes various attempts at creating molds and […] Wanna make a DrawBot? Ashley John Pigford // Design is good for you. // Forty-five states in the U.S. have chosen to adopt the Common Core State Standards in order to give the nation a shared curriculum.

The Common Core State Standards does not require children to learn how to write in cursive. The Common Core Standard for writing (W.4.6) states that by the end of fourth grade, students should demonstrate sufficient command of keyboarding skills to type a minimum of one page in a single sitting. We made this interactive installation at the Delaware Center for Contemporary Arts to illuminate the beauty and importance of cursive handwriting. The Cursive Machine portion of this installation was part of the Void Loop exhibition at Press Street’s Antenna Gallery in New Orleans, and included in a news report on WGNO (ABC) TV.

The primary feature of the installation is the Cursive Machine, created in collaboration with my father, Robert H. 20 Arduino projects of 2012. While looking for ideas for new some new project I noticed there aren’t many lists of Arduino projects online so I decided to make one and in the last few days I’ve been carefully digging Reddit (r/Arduino) and the Arduino forum until I ended up with a list of 20 Arduino projects.

20 Arduino projects of 2012

All the projects in this list follow two simple criteria: They’ve been published/released in 2012.They provide quite detailed info (the more the better). The second criteria forced me to discard some amazing projects, but I didn’t want this post to be a simple showcase of cool Arduino projects, I wanted it to be an useful reference for Arduino users. 20. arduino-l3dgecomm.

Plusea. Embroider highly conductive thread to make a fabric speaker coil.

Then run an amplified sound source through it and hold a magnet close to hear it play. Sewing the coil takes longer than you might think! >> Fabric Speaker post >> Instructable >> Speaker Coil Flickr photo set >> Download Instruction PDF Materials included. Pin Battery 50 Pack. Back to Store Pin mount lithium coin cell battery. Great for paper electronics and powering simple circuits. Voltage: 3V. Sweep. Learning Examples | Foundations | Hacking | Links Examples > Servo Library Sweep Sweeps the shaft of a RC servo motor back and forth across 180 degrees.

This example makes use of the Arduino servo library. Hardware Required Arduino Board (1) Servo Motor hook-up wire Circuit Servo motors have three wires: power, ground, and signal. Click the images to enlarge images developed using Fritzing. Projects using the Teensy USB development board. Adafruit Motor Shield. Stepper motors are great for (semi-)precise control, perfect for many robot and CNC projects.

Adafruit Motor Shield

This motor shield supports up to 2 stepper motors. The library works identically for bi-polar and uni-polar motors For unipolar motors: to connect up the stepper, first figure out which pins connected to which coil, and which pins are the center taps. Arduino Servo Tutorial 1 of 2. KnockSensor. Learning Examples | Foundations | Hacking | Links Here we use a Piezo element to detect sound, what will allow us to use it as a knock sensor.

KnockSensor

We are taking advantage of the processors capability to read analog signals through its ADC - analog to digital converter. These converters read a voltage value and transform it into a value encoded digitally. In the case of the Arduino boards, we transform the voltage into a value in the range 0..1024. 0 represents 0volts, while 1024 represents 5volts at the input of one of the six analog pins.

Arduino Sound Alarm « flow. I’ve just completed my second Arduino project, a sound level detector which sets off an “alarm” when there’s the sound level is to high for too long. I built it for use in a school that wants to provide visual feedback to students when they are being too loud.

The “alarm” is a string of flashing LEDs that’s controlled by an IR-remote, which I reverse engineered using the the arduino itself and the excellent IRremote library to figure out which codes activate the LED string. l3dgecomm for Arduino. L3DGEWorld is a tool for monitoring and interacting with networks and computer systems. Within a 3D world, entities bounce, spin, scale and otherwise change. These entities all represent an entity in another context - be it a server, phone, router or other monitorable device.

The visual transformations represent various characteristics of these entities, such as packets per second, CPU load, memory usage or temperature. The use of visual characteristics to represent important metrics allows an administrator to quickly see an overview of their systems, and especially whether there are any anomalies. Input and output is taken to/from daemons using l3dgecomm . Arduino-l3dgecomm allows for an all-new type of input and output to L3DGEWorld, implementing l3dgecomm for the Arduino.
