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).

LIR2450 Li-Ion Battery and Charger

The LED Artist — Thu, 18 Jul 2013 04:00:19 +0000

LIR2450 is a coin cell, Lithium-Ion rechargeable battery. Physically the same size as CR2450, LIR2450 can be used as a rechargeable replacement to CR2450 in most cases.
This little battery has little over 100 mA/Hour capacity, with nominal 3.6 V output. This battery is perfect for powering a small project.
The problem (for me) was that there were only poor quality chargers available for this very useful battery. Since I could not find a good charger for it, I made one.

This charger is based on the popular MCP73831 by Microchip to charge Lithium-Ion battery safely.
The charger is very compact and plugs right into an USB port.

Features/Notes:

Compact design plugs into an USB port
Charge/Done LEDs indicate the charge status
Charge current: 45 mA typical
Charge time: about 3 hours
Dimension: 1.15 x 1.45 x 0.38 inches

Audio Interface for Aurora – Through-hole version

The LED Artist — Sun, 17 Feb 2013 05:19:04 +0000

This Interface turns Aurora 9×18 mk2, Aurora 18×18 or Aurora 12 bar into the ultimate color organ. This is the through-hole only version of the same exact circuit as the original Audio Interface.

You can watch the video here.

The interface goes between the power cable and Aurora, using Molex 3 pin connectors. The interface has a 3.5mm stereo audio jack, so you can connect any audio output. There’s a potentiometer to adjust the sensitivity level as well.
Aurora 12 bar, Aurora 9×18 mk2 and Aurora 18×18 have audio or “color organ” modes, which you can select by either pushing the on board button or using a remote control (remote not on Aurora 12 bar).

Color Organ Triple Deluxe II – Kit and PCB

The LED Artist — Mon, 14 Jan 2013 23:21:26 +0000

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

The LED Artist — Sun, 06 Jan 2013 00:11:08 +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 is made with 100% through-hole parts. No surface mount parts!

Kit Contents
12x RGB LED (common-cathode)
3x 2N2907A or equivalent Transistor
1x PIC24FV16KA301 Microcontroller (Preprogrammed with the latest firmware)
1x Tactile Switch

Battery Cases

The LED Artist — Fri, 12 Oct 2012 21:32:20 +0000

Here are handy battery cases for driving Aurora with batteries. These hold two, three, or four AA batteries, and has a power switch. The cords are terminated with a 2 pin Molex female connector (standard 2.54 mm pitch), so connecting to Aurora is a snap.

In general, Three batteries are recommended, but two Alkalines work ok (LEDs will not be as bright) with Aurora 12 bar or Aurora mini 18. For Aurora 9×18 and Aurora 18×18, use of four AA batteries is recommended.
Two AA battery configuration is only effective if you are using Alkaline batteries. Rechargeable batteries such as NiMH or NiCD have lower voltage, so at least 3 of them need to be used to power Aurora.
