Collider 60

The LED Artist — Thu, 15 May 2014 15:45:19 +0000

Collider 60 is a very simple device – 60 LEDs on a square board, a knob in the middle. Lights run in a circle and the speed is adjustable by turning the knob.
Connect two or more Colliders and see the magic happen. When the lights run and hit the same spot at the same time, they “collide” as though they are running bullets, making clicking sound and change direction. By adjusting the rotation speed of each unit, the “collision” happens at a different interval.

The real fun starts with three or more units connected together. The results are no longer predictable.

Collider reminds us how all complex things in nature is comprised of simple roles. When you have enough number of “simple” things reacting together, you get unpredictable and interesting results.

A12 – Wearable LED Gadget with Full-Color LEDs

The LED Artist — Wed, 02 Oct 2013 04:00:00 +0000

New addition to my wearable LED accessories is A12. A12 is the same size as R48, uses the same microcontroller and battery, but with 12 full-color LEDs. A12 produces patterns similar to Aurora mini 18, but lighter and has a built-in battery holder in the back.

A12 comes with a non-rechargeable battery (CR2450) and a black cord (lanyard) to hang around the neck. The battery lasts for about 5 hours or more in continuous run.

There are also rechargeable battery (LIR2450) and the charger available. With those, you won’t need to keep buying batteries.
The charger is very compact and plugs right into an USB port.

Features/Notes:

12 full-color LEDs produce beautiful colors.
A12 is available fully assembled or soldering kit.
Comes with a non-rechargeable battery (CR2450, easily replaceable).
Battery will typically last about 5 hours continuously.
Also comes with black cord (lanyard) to hang around your neck.
10 beautiful animation patterns preprogrammed.
“Demo” mode automatically runs though all animation patterns – changes every minute. (Activated by holding the button at the startup.)
Rechargeable battery (LIR2450) is also available as an option. This recommended option lights the LEDs brighter, as it has higher voltage.
The charger for the above is also available.
Dimension: 1.9 inch diameter, 0.4 inch thick (including the battery)

Technical Details:

12 common-anode RGB LEDs.
PIC24F08KL301 16 bit microcontroller @ 32 MHz.
Each LED is PWM controlled in 128 gamma-corrected levels.

Installation at Ingenuity Cleveland

The LED Artist — Thu, 26 Sep 2013 15:49:04 +0000

Just came back from Ingenuity Cleveland art festival. I installed a piece titled Rainfall.

Rainfall consists of 24 vertical lines of LEDs on a wall 16 feet wide and 8 feet tall. Each line is made up of 10 modules with a microcontroller and 48 LEDs, so the total of 240 microcontrollers (plus a hidden main controller) and 11,520 LEDs are used.

Wiring up all of those modules were a pain, but I got through it.

The installation was a success. People were stopping and gazing at the piece, then taking pictures and video.

After the festival was over, the installation was moved to Cleveland Public Library, where it will be on display for 3 months.

I had a great time in Cleveland. Thank you so much everyone!

R48 and Li-Ion Charger

The LED Artist — Thu, 18 Jul 2013 21:35:24 +0000

R48 comes with a non-rechargeable battery (CR2450) and a black cord (lanyard) to hang around the neck. The battery lasts for about 7-8 hours in continuous run.

There are also rechargeable battery (LIR2450) and the charger available. With those, you won’t need to keep buying batteries.
The charger is very compact and plugs right into an USB port.

White LEDs look yellow when they are not lit. Other colors (red, green, and blue) look like the photo above.

Features/Notes:

Available with 4 different color LEDs: Red, Green, Blue, and White.
Each R48 is fully assembled, and comes with a non-rechargeable battery (CR2450, easily replaceable).
Battery will typically last about 7-8 hours continuously.
Also comes with black cord (lanyard) to hang R48 around your neck.
25 beautiful animation patterns preprogrammed.
“Demo” mode automatically runs though all animation patterns – changes every minute. (Activated by holding the button at the startup.)
Rechargeable battery (LIR2450) is also available as an option. This recommended option lights the LEDs brighter, as it has higher voltage.
The charger for the above is also available.
Dimension: 1.9 inch diameter, 0.4 inch thick (including the battery)

R48 – an Wearable LED Gadget Pre-order Starts

The LED Artist — Sun, 30 Jun 2013 20:34:43 +0000

Here’s the sneak peak at the upcoming wearable piece – R48. (I promise that better video will come soon.) Four different LED colors (Red, Green Blue, and White) are planned, but the first color available would be blue.

The item will be in stock in the 3nd week of July, and the price will be $49. Pre-order starts now at $45 a piece.

Also available are optional rechargeable Lithium-Ion battery and the charger. The charger is very compact and plugs into an USB port. The photo below is showing the prototype. The final version will look better in black. (Will post the photo as soon as available.)

Features/Notes:

Each R48 will be fully assembled, and comes with a non-rechargeable battery (CR2450, easily replaceable).
Battery will typically last about 5 hours continuously.
Also comes with a black cord to wear R48 as a neckless.
25 beautiful animation patterns preprogrammed.
“Demo” mode automatically runs though all animation patterns – changes every minute. (Activated by holding the button at the start up.)
Rechargeable type battery (LIR2450) is also available as an option. This recommended option lights the LED brighter, as it has higher voltage.
The charger for the above is also available.
Dimension: 1.9 inch diameter, 0.4 inch thick (including the battery)

R48 is now shipping – pre-order is ended.

New Items Debut Tomorrow @ Maker Faire

Aurora 12 bar – All Through-Hole, All New

The LED Artist — Sun, 06 Jan 2013 00:14:33 +0000

Aurora 12 bar is a simple, straight line RGB LED sequencer/chaser. Aurora 12 bar’s hardware is almost identical to Aurora mini 18. In fact only difference are (besides their shapes) the number of LEDs and the microcontroller that they use. Oh, and Aurora 12 bar doesn’t use a single SMT (surface mount technology) part!

In addition to all the animations that other Aurora’s can do, Aurora 12 bar also has the analog input ready. By hooking up to Audio Interface, you can turn Aurora 12 bar into a full-color sound/VU meter!

- Aurora 12 bar Schematics

Video and Instructables are in the works, however the kits and PCBs are ready to go.
