Speed Vest for Night Cycling

Monday, October 10th, 2011

[Mykle Hansen] explains how to make a Speed Vest displaiyng the speed of the bicycle, as seen on Make: 19. This is a cool intro-project for wearable electronics.

Bicyclists receive a lot of honk-based grief from car drivers who perceive them as slow and in the way, and when drivers misjudge a bicycle’s speed, it can cause “right hook” collisions that kill several bicyclists each year. This lightweight night-cycling vest displays your current speed in glowing, 7-inch-tall numbers easily visible to cars. On the back, an Arduino microcontroller reads input from an off-the-shelf bike speedometer sensor, and then switches power to sewn-in numerals made from electroluminescent (EL) wire.

Retro Pinball Clock Hack

Wednesday, October 5th, 2011

[Alan Amon] posted a cool vintage hack on Instructables, adding GPS-based clock funcionalities to a Bally Wizard pinball.

Pinball machine will automatically power up at the preset time each day and then resets to display the current time, the year, the time the alarm is set for and the date month/day. Then as long as the GPS has a signal the time will update once a minute for the rest of the day.  At the time you would like to go to bed the Arduino will cut power to the game and it will remain off until the alarm time. Should you have a power failure in the night the machine will not lose it’s settings. If power is restored prior to the alarm time the machine will wake up as normal, otherwise the machine will wake up once power is restored.

If the game is powered on because it is not yet bed time and it is after the alarm time then at 12am, 1am or 1pm the game will do a full reset. This makes sure the clock hasn’t gotten off due to a stuck score reel, keeps the time in a 12 hour format and keeps the date display up to date.

Have a look at the “cool features” and “coolest features” in the instructables article

Time To Go Matrix

Tuesday, October 4th, 2011

We are happily announcing two new products in the Arduino Store: [E000011] 32×08 Red LED 5mm Matrix and [E000013] 32*16 Green/Red LED 3mm Matrix from Sure Electronics. Both products are coming with tutorials and related projects.

Have a good prototyping!

 

 

 

 

Leaf Planetarium Lets You Watch The Stars From Bed

Thursday, September 1st, 2011

[t3chnolochic] made a leaf planetarium based on IKEA design and Arduino.

Long story short, 400 ft of fiber optics, 6 power LEDs, and a lilypad arduino later, I present to you, my giant twinkling leaf planetarium.

Want to make one yourself? She wrote an Instructable about it.

When music meets Arduino

Monday, August 29th, 2011

A beautiful project by [Leigh Davis]. It is a brilliant proof of how Arduino fits into virtually any sphere of thought and is the shortest path for a creator realizing his idea in reality.

He writes:

I began the first few days by developing a stand alone application build in MaxMSP that understands the notes that a play on my (recently purchased second-hand) flute. I set the range from low C right up to the 3rd octave D. Each note of the chromatic scale triggers a bang, which is coloured uniquely to the other notes bang messages.

The bang message then sets the corresponding color to the display screen on the application. Which will in turn send a signal to the arduino to dispense the corresponding oil color on water according to the different notes. (Something like a physical Milkdrop!)He further plans to control different LEDs, motors and the likes using the Rayne application.

A Wall of 250 Canon Cameras Flashing Their Lights In A Matrix

Wednesday, August 3rd, 2011

Japanese band Androp realized for it’s latest single “Bright Siren” a 250 Flash light-based interactive Matrix.

Japan musicians Androp built a backdrop of 250 Canon cameras and programmed all their flashes to fire off in a sort of digital stop-motion screen.

The “Making of” after the break.

IAAC's CAN-Based Interactive Architectures

Monday, August 1st, 2011

Barcelona-based IAAC school is hosting a summer school (in Barcelona and Mumbay). The theme of this year’s course is creating an urban tool of a networked city based on a new informational layer.

What happens if we think Urbanism and Energy through a new informational layer added in our cities?

“Light Scythe” Lets You Do Huge Light Paintings

Tuesday, July 5th, 2011

Some of you may know “light painting”  it’s a photographic technique which uses long exposures and a light source, to “paint” the photo with light. The project was inspired by the Wifi Netword Visualization, The Mechatronics Guy later brought in the concept of writing and painting pictures with the beams of light with a pc (wirelessly via Xbee).

The hardware is pretty simple. There’s a 2m programmable LED strip inside an acrylic tube, which is controlled from a small receiver and battery pack. A laptop PC with a wireless Xbee link sends the image data to the scythe at a specified time.
