Out of Stock? We've received a lot of emails asking about out of stock items, and sad to say, but CI is downsizing to a much smaller product offering. All of our guides, schematics and blog entries will stay available forever. Our new project is VMeter--a USB MIDI Controller Touch Strip & Display. |
Controlling 4 or More Servos Demo Arduino Code
February 23, 2009 7:47:00 AM EST
The newest version of arduino has a SoftwareServo library built in, which lets you use more than two servos at once. This code is a simple example of how to control 4 servos via keyboard from the SerialMonitor mode of arduino. If you have arduino12 software, you'll need to manually add the SoftwareServo library as described in the included readme.txt file.
The code is available as a getting started example on our roboduino kit page. Read More

February 20, 2009 2:43:00 AM EST
Robert Dew did some amazing tack-soldering on the bottom of a No-Lead chip to make a simple break-out board without any special PCBs. He says it took a lot of trial and error and flux. The chip is an accelerometer.
Robert made the break-out board for the EE senior design class and electronics lab at GaTech.

February 17, 2009 11:38:00 AM EST
Georgia Tech Music Dept. is hosting the Guthman Musical Instrument Competition Feb 27-28. If you're in the area, it looks to be an interesting event.
"The first Guthman Musical Instrument Competition presented by GTCMT and Harmonix (makers of Guitar Hero and Rock Band) will award $15,000 to the best novel musical instruments as judged by a panel of experts from Harmonix, Wired, and Georgia Tech.
Entrants must perform a musical work with their new instrument to demonstrate its musicality, design, and engineering features. Performances may include traditional acoustic and/or electronic instruments alongside the new instrument. They may also include multimedia elements such as video, animation, graphics, text, kinesthetics, hydraulics, dance, or acting.
Judges include Eran Egozy, the co-founder of Harmonix (Guitar Hero Co-Founder), Eliot Van Buskirk from Wired, and a professor from the Georgia Tech Center for Music Technology.... "

Read MoreArduinome Case Prototyping
February 17, 2009 1:03:00 AM EST
We've finally got an Adruinome (monome made from Arduino + SF buttons) case design being cut up at our favorite laser cutter (ohararp.com). It uses the same T-bolt style connecting system as our monome case, and has mounting holes for the Diecimila. We're going to do a small first run, what colors would you like?

January 27, 2009 9:04:00 AM EST
Beatrix*JAR puts on a show at the Eyedrum in Atlanta and does a circuit bending workshop following the show where they explain how they make and use Speak n spells, AM radios, flash cameras and old casio keyboards.
One very cool effect involved an AM radio and two flash cameras, which can be used as a makeshift theremin by charging the cameras and moving them around the AM radio. When the flash is triggered it lets off an explosion of sound on the radio.
In the circuit bending workshop, they show how to warp an old casio's sounds by randomly bridging points on the insides. This was surprisingly effective and no magic smoke was seen. They also embedded nails into some speak-n-spells that would warp the pitch depending on how hard the nails were pressed.

Read MorePCB as a Heat Sink + Calculating Trace Width for Given Current
January 23, 2009 6:10:00 AM EST
This entry will take a dive into heat and temperature issues surrounding circuit layout design, including the effectiveness of the PCB itself as a heat sink when a voltage regulator’s heat sink is soldered directly to the board, and how to size trace widths for given current loads.

Read MoreScrubbing Sampler with Stribe1s and monome
January 14, 2009 1:58:00 AM EST
The demo uses the monome to trigger different play positions in loops and Stribe1s to adjust playback speed, pitch, and to scrub / scratch through the samples. The software is written in max/msp and is based on granular synthesis, which breaks the sound into small chunks that get overlayed and blended together. The code (dirty beta) will be linked at the end of the post.
Stribe1 Monome Sampler Scrubber from CuriousInventor on Vimeo.
Code: max/msp code. (warning, VERY ugly and will take some pecking to get operational. post questions in the forums, not in the comments here).
Thanks to Andrew T. for the Stribe1 / monome arrangement idea. Read More
How the Yellow Line is Drawn in Football Coverage
January 9, 2009 4:31:00 AM EST
As you might expect, the camera position, angle, zoom etc are fed back to computers where the green field is replaced with yellow. Interestingly, one operator's entire job is to match the replacement color to prevent the line from drawing on top of players when it's muddy or foggy. Are green pants illegal now?

Name That Component: Taking apart a 1983 Floppy Drive
January 7, 2009 2:19:00 AM EST
Taking apart a floppy drive from 1983 that was longer than most computer cases, we found some interesting components you don't see much today. Like an old car, things are a lot more spread out and bigger, so it's easier to see how things work. Click the title for more pics.

Read MoreNixie Tube Gmail Unread Mail Count / Notifier
January 5, 2009 2:48:00 AM EST
Inspired by the glowing cube gmail notifier, and having been given a nixie duo + driver from ogi lumen, this entry demos how to make a nixie display that shows the last two digits of your gmail unread count. It uses a python script to check your gmail atom feed, a $7 disposable camera circuit to power the tubes at 170VDC, and a roboduino (or any arduino compatible) board to control the nixies from the computer via USB serial.

Read MoreDIY QFN Breakout board
December 31, 2008 5:59:00 AM EST
Starlino has a neat technique for making a cheap breakout board for lead-less QFN chips. In brief:
The best part is that no hot air or breakout board is required. Read More
- Drill a hole in a proto board so that the chip barely fits inside and has its connections on the same plane as the board. Fill gaps with epoxy or putty.
- Tape over everything except one pad and and small path to the proto board.
- Use a conductive ink pen to lay a path. Remove tape before the ink dries to keep from breaking the pathway when it hardens. Wait for it to dry and repeat on the other pads.
The best part is that no hot air or breakout board is required. Read MoreNew Kit: tinyCylon - Battlestar Galactica Inspired LED Display
