When we realized that George had posted a template for this sculpture we dropped everything, grabbed the cardboard and hot glue, and raced to build our own.
You’ll need papercraft type building materials: Paper, cardstock, or cardboard, and tape or glue. Also good scissors and/or a hobby knife with sharp blades. You can also build this with wood, plastic, or other materials, of course, but cardstock and cardboard are inexpensive and effective. Hot glue also proved to be excellent, providing sufficient strength and flexibility, and good working time.
You can download the PDF template for Frabjous on its web page.
I have one of those USB-based logic analyzers that needs Windows software to make it go. I had been doing Windows-in-a-window with VMWare, but it’s kind of a pain. If I were to use a real Windows laptop, I’d need a shelf or something for it. I wanted it above my oscilloscope, which meant a laptop stand that was taller and wider than most. Time for the laser cutter!
The MaxSonar EZ1 provides very short to long-range detection and ranging, in an incredibly small package. It can detect objects from 0-inches to 254-inches (6.45-meters) and provides sonar range information from 6-inches out to 254-inches with 1-inch resolution. (Objects from 0 inches to 6-inches range as 6-inches.) The interface output formats included are pulse width output (PWM), analog voltage output (Vcc/512 volts per inch), and serial digital output (9600 baud).
Tilt ball switch – The “poor man’s” accelerometer! Tilt sensors are switches that can detect basic motion/orientation. The metal tube has a little metal ball that rolls around in it, when its tilted upright, the ball rolls onto the contacts sticking out of end and shorts them together. There’s no datasheet but they’re fairly easy to use! In the store now!
Unfortunately, the SpokePOV is only one colour, and the m132s, as I understand, doesn’t have the ability to display images. Besides, I think these are a little too expensive for something that I will not use often.
So I though I would try to make my own with components I already had around. This way I don’t have to spend any more money to try and play with a bicycle POV.
This project features:
16 RGB (Red+Green+Blue) Light Emitting Diodes;
Arduino compatibility (Suposedely, I’ll have to check that later);
Single layer printed circuit board, suitable for home fab;
All through hole componentes, suitable for beginners;
Hall effect sensor, for image synchronization;
Least number of componentes possible;
Unfortunately, only one side of the wheel is illuminated (check update).
Fits 26″ wheels, I haven’t had opportunity to try it in 20″ and 24″ wheels.
This project is also a open project. Anyone who wishes to participate is welcome. The contributions will be added to this instructable and published.
Want to learn how to work with electronics and microcontrollers but need a little help? You’ve come to the right place! This bundle is designed to get you started quickly and easily on your path of learning electronics. Once you’ve received your starter pack you can follow the introductory tutorials here on our site, designed for everyone, even people with little or no electronics and programming experience. The starter pack has everything you need (except tools) for all lessons.
9V DC regulated wall adapter – You can power your Arduino from any wall socket. This switching regulator is efficient and small and works with US (110V) and European (220V) power.
9V Battery case with switch and a 2.1mm plug- so you can power your arduino using a 9V battery. This case is much sturdier than just a battery clip and it has an on/off switch too! Note that this comes unassembled by default.
Tutorial starter pack parts – Includes a 10K potentiometer, 1K potentiometer, 2 small pushbuttons, 5 red diffused bright LEDs, one each of red, green and blue ultra-bright LED, 5 100 ohm resistors, 5 1K resistors, 5 10K resistors, and a CdS photocell sensor.
The Liquid Font Family is a collection of small bitmap fonts to be used on small displays, e.g. LCD displays on HTPCs, mp3-players, status displays on phones, printers, remote controls, etc.etc.
The overall goal is to provide nice-looking, very readable fonts that allow displaying a lot of information. So in contrast to most other bitmap font projects for tiny fonts, Liquid fonts are proportional fonts, not mono-spaced, because more characters can be displayed horizontally this way, and it also looks nicer. This means they require graphics capable displays. In particular, they are not primarily for 5×7 pixel LCDs, which have hardwired(=missing) horizontal and vertical empty pixel rows and columns to separate characters and lines.
The main work of the Liquid family is ‘Liquid Mean’. This font is a 6×8 pixel font which additionally focusses on good Unicode support. Currently, it already supports Latin, Greek and Cyrillic for a few hundred languages. It implements a superset of the European MES-2 standard, a recommendation for European Latin/Greek/Cyrillc fonts to support the vast majority of European languages, including most minor languages.
Liquid Mean goes beyond that. The support includes many more languages, even those which require a vast amount of accents and diacritic marks, like Ancient Greek, Vietnamese, and Mandarin Chinese Romanisation.
Liquid Mean explores what amazing things can be done on a very limited display with max. 6×8 pixels per character.
An online editor for the Craft and Make magazines, Becky Stern is deeply involved in the DIY community. Stern took her love for programming and crafts and meshed it into an embroidered piece that puts a microcontroller board called the LilyPad Arduino at its center.
The LilyPad is a microcontroller board that can be sewn to fabric with conductive thread. The board was designed and developed by Leah Buechley and SparkFun Electronics and it was an idea that fascinated Stern.
Stern took the board and embroidered it into a floral pattern. She added lights and sounds activated by sensors and the microcontroller software. Moving your hand over the piece results in changes in light and sounds generated from the fabric.
EnergyLogger is a simple, native, cross-platform application designed to take the place of the Python scripts developed for the original Tweet-A-Watt project. By providing a user-friendly GUI interface for monitoring and logging data from these wireless enabled meters, we hope to remove one of the barriers to entry when implementing this project for yourself.
In addition to tweeting daily usage statistics, EnergyLogger is able to:
Log interval data to a CSV text file,
Upload interval data using Google’s Data API protocol to a Google Doc spreadsheet for analysis by other Google Apps or for use by Google PowerMeter,
Monitor energy usage and raise an alarm when load remains outside upper or lower limits for a user specified amount of time,
and “Tweet” these alarms to a user’s Twitter account.
The data files created by EnergyLogger can be imported directly into EnergyProbe, our flagship energy analysis software delivering an inexpensive, powerful, wireless solution to record, understand and interpret energy usage which had previously cost many thousands of dollars.
The 802.15 wireless standard implemented in the XBee radios allows EnergyLogger to monitor up to sixteen separate Kill-A-Watt meters simultaneously. Data is collected approximately every 2 seconds, processed, logged and uploaded at user defined intervals.
The interface is simple to navigate, provides all the pertinent information at a glance and can be made to disappear into the system tray or menu bar, doing it’s job in the background while your computer is free to do other tasks.
