A12 – Wearable LED Gadget with Full-Color LEDs

A12 Twinkle




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.

Color Organ Triple Deluxe II – Kit and PCB

Color Organ Triple Deluxe II is the return of the classic color organ of the 70′s using LEDs. Color Organ divides sound wave into three bands; low, mid, & high, and lights different color LEDs based on the volume.


Color Organ Triple Deluxe II uses all discrete transistor circuit for authentic “sound to light” function – no ICs, no microcontrollers. Assembly is also very straightforward and beginner friendly.

Notes:
Kit assembly requires basic soldering skills.
You need a 12V DC power supply (AC adapter) (300mA or higher current capacity – such as this one) to operate Color Organ Triple Deluxe II. Use of regulated power supply is recommended, since non-regulated AC adaptors typically produce output voltage much higher than they are rated. (Typical “12V” non-regulated AC adaptors can output about 18V.) If you want to use one of those, make sure to masure the actual output voltage, and only use it if the voltage is lower than 15V. (Try 9V rated ones.)

Aurora 12 bar – Kit and PCB



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 is made with 100% through-hole parts. No surface mount parts!

Kit Contents
12x RGB LED (common-cathode)
3x 2N2907A or equivalent Transistor

Aurora 48 Kit

Aurora 48 is a compact and thin profile full LED sequencer. It’s built entirely with surface mount components, so the profile is nice and clean.

  • Capable of individually controlling 48 Full color LEDs.
  • Each LED can be faded in 7 bit per channel - 2,097,152 colors.
  • Gamma corrected brightness curve for very smooth fades.
  • Simple, one button control.
  • 11 sequence pattern (as of firmware version 1.0).
  • Compact – 2.68 inch (68 mm) in diameter.
  • Thin profile construction (0.137 inch (3.5 mm) thick).
  • No leads sticking out on the back. Ideal for wearable projects.
  • Firmware is easily upgradable via 5 pin ICSP connection.

Please review the instructables before purchase – assembly requires some skills. You will also need PIC programmer such as PICKit 3, ICD 2, ICD 3 (PICKit 2 doesn’t work with the PIC used). If you don’t have a programmer, you can purchase the PIC programmed with the latest firmware.

USB Blinky Kit

USB Blinky light in action
USB Blinky Parts

USB Blinky is possibly the simplest LED blinky kit out there. There are only ten parts to solder. The PCB (Printed Circuit Board) itself plugs right into an USB port. Thicker material is used for the PCB, so that it fits into the USB port nicely.

USB Blinky blinks at about twice a second. USB Blinky only draws little current (about 5mA) so any USB ports can power it.

USB Blinky is the perfect “Learn to Solder” project.

Wave JT – Kit and PCB



Wave JT is a tiny LED sequencer or “Larson Scanner” on steroid. It has over 16 sequence patterns, and speed can be adjusted by double/triple tapping the button. It’s the most versatile LED chaser.

Unlike other LED chasers, Wave JT controls each LED in smooth 7 bit (128 levels) brightness levels. The brightness curve is gamma-corrected like Aurora series, so the fades are visually pleasing.

Not only Wave JT versatile, it’s also energy efficient. Wave JT runs on a single AA battery, and the battery lasts for days!

Poorman’s Buck – High Power LED driver


Poorman’s Buck is a simple, constant-current high power LED driver capable of driving 350mA to 1A of output current. It is compact (footprint is 1 x 1.5 inches) and easy to build, yet very versatile.

Input power supply voltage can be anywhere between 5 to 20V (must be higher than the connected LED’s forward voltage drop). Up to 5 LEDs can be connected in series, and by parallel connecting the series connected LEDs, up to 18W total of LEDs can be driven (with 20V power supply).

Output current is configurable; 350mA, 700mA, or 1A using included parts. In board potentiometer can lower the output current down to about 9% level – which can be used as a dimmer. Full dimming control can also be done via the PWM input, making Poorman’s Buck a perfect building block for Arduino or other microcontroller projects.

For technical details please view my instructables.

You can purchase full kits or just the PCBs. Please use the buttons below to purchase.

Aurora 9×18 mk2 Kit and PCB

(The original Aurora 9×18 video)

The kit includes everything you need to build Aurora 9×18 mk2, plus mounting screws & nuts. Those screws can also help you when you solder in the LEDs, by giving the PCB a lift off the working surface.

The smallest SMD parts are 0603 size, which is quite tiny. Naturally it’s very easy to lose them while assembling. Since it’s not much fun having to buy those little parts because you lose them, I’m including a few extras for all 0603 size parts. There are a few extra LEDs included as well. Hopefully you won’t have to stop the assembly because you’ve lost a few parts.

View the technical info here.

- View the soldering/assembly guide.

IMPORTANT: You need a compatible PIC programmer such as PICkit 3, ICD2/3, etc. to program the PIC. (PICkit 2 does not support the newer PICs used on those Auroras.) If you don’t have access to program the PIC, you can choose “programmed” option for additional $5. The PIC IC will be soldered to the PCB in order to be programmed.

Aurora 9×18 and Aurora 18×18 pre-order deals

*** These pre-order deals have ended on midnight(EST) of April 8th (Sun).
Please refer to the current pricing here. ***

I have finalized the designs of new Aurora 9×18 mk2 and Aurora 18×18. Developing these things takes a lot of effort, time and of course, money.
I really want to make those Aurora’s available as kits, however I need a small capital to do so quickly. Otherwise I’d have to wait.

So here’s the deal, I will offer those kits at 20% discount until I have them shipping. Once the kits are in, the final prices will be $179 for Aurora 9×18, and $289 for Aurora 18×18. (At the worst case where I could not deliver those kits, your money will be refunded. PayPal will offer protection against non-delivery, so rest assured.)
I’m really hoping that with your help, these kits will be shipping within 4 weeks.

IMPORTANT: Like all other kits I sell, PIC microcontrollers are not preprogrammed. You need a compatible PIC programmer such as PICkit 3, ICD2/3, etc. to program the PIC. (PICkit 2 does not support the newer PICs used on those Aurora’s.) This is due to the fact that surface mount PIC need to be soldered to a PCB before being programmed.
