New R48 Video Clip

Finally, a short but sweet video clip of R48 blue. I hope you enjoy…

> R48 blue and accessories


R48 and Li-Ion Charger

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)

In-stock and shipping now!


R48 – an Wearable LED Gadget Pre-order Starts

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.


Aurora 48 Sequence Video

Here is a video of Aurora 48 showing all of its preset sequence patterns. Watch it in full screen – it’s full 1080p HD.


Wave JT – LED chaser with Joule Thief

Wave JT is a multi-function LED chaser/scanner/sequencer. Wave JT incorporates Joule Thief to power the LEDs, so it operates on just a single AA battery.
Wave JT has over 16 sequence patterns, and speed can be adjusted by double/triple tapping the button. It’s the most compact yet versatile LED chaser.

Sequence patterns include many variation of the classic “Larson Scanner” from “Knight Rider”, random sparks, fade in/out, flashing, etc.

Even though there is only one button switch on Wave JT, you can control many things with it.

Aurora mini 18 Firmware Update

Aurora mini 18 now has three new animation patterns added. These new patterns are based on random numbers, instead of smooth transitions of original patterns. Now Aurora mini 18 has total of ten patterns for more fun.

What! Aurora 18×18!


I know I just announced the Aurora 9×18 mk2 to be arriving soon. However I’ve also been working on this big brother to Aurora 9×18 – Aurora 18×18. I’ve finished the prototyping and finalized the design. The above is the composite image of the final design. (outside diameter is 7 inches)

I couldn’t wait any longer to share it with you.

Please note that those are prototypes in this video. Two of them are slightly different, and the final version will be very much like between the two (as far as the LED layout is concerned).

Like Aurora 9×18 mk2, Aurora 18×18 has infrared remote control receiver, so you can use any remote controllers that can control Sony TVs to control Aurora 18×18 – mode/pattern change, speed control, pause, and power on/off. (All universal remote controllers I know can control Sony TV)

Provision for the optional audio interface is also there. (Update: here’s the video and the pics.)

Here are the specs:

  • PIC24FV16KA304 microcontroller
  • GP1UX311QS or equivalent IR remote receiver
  • 324 x 5mm RGB LEDs (common-cathode)
  • 3 x MOS FETs
  • 18 x NPN BJTs (Transistors)
  • A push button switch
  • Requires DC 5V, 500mA power supply (1A capacity recommended. USB power is ok)
  • Board diameter is 7 inches

(More technical info is here.)

Now I need your help to bring Aurora 18×18 into self assemble kits like other Aurora’s. In order to do that I need a small capital to start the production of PCBs, etc. So I’m offering a “pre-order” deal to speed things along.

Please view the post here about the pre-order deal. Hope you can help.


Aurora 9×18 Teaser Video

I thought it’s time for me to start putting some effort in creating better presentation of the work I do. Here are two versions of video that showcase Aurora 9×18.


Sneak Peek

Here’s a sneak peek at the new creation. Those small (4 inch dia.) ones are created as teaser/samples of my other, larger objects.

Each has 144 white LEDs. 8 channel PWM to create smooth motion of lights. This microcontroller (PIC16F616) only has one 10 bit PWM module, however I’m combining the hardware PWM with software PWM to create very smooth (equivalent to 16 bit or more resolution) gradation.
