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.

I revised the international shipping fees. The recent changes of postal fees made it very difficult to provide reasonable shipping fees to non-US customers. However I’ve signed up with a bulk mailing service, which made possible to reduce international shipping fees.
You will notice “International Economy” shipping option when you go through the checkout. The orders will be shipped via USPS First Class mail, which is very economical. Please note, however this option does not provide any tracking. If you want tracking and quicker delivery, please consider “International Express Air”. “International Priority Air” is quicker than Economy, but still doesn’t provide tracking…
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 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!
Video and Instructables are in the works, however the kits and PCBs are ready to go.
I discovered a bug that prevents start up at the power on. The condition is relatively rare, but if your Aurora 9×18 mk2 or Aurora 18×18 is suffering from occasional lookup at the power up, please reprogram the PIC with the updated firmware.
This firmware (version 1.4) is also revised to keep the speed change setting in the EEPROM (note: speed adjustment is only possible via IR remote), so that your set speed will be restored after power off/on.
Please let me know if there are any issues with this updated version.
- Aurora 9xx18 mk2 firmware: aurora9x18mk2-1.4.hex
- Aurora 18×18 firmware: aurora18x18-rev2d-v1.4.hex
Due to Hurricane Sandy, we are experiencing shipping delays. Our area did not get much damage, but postal service is not working.
I think everything will go back to normal in a couple of days.
*** UPDATE: We are back to normal. USPS is reporting normal delivery. ***

Steven Hibs created this beautiful Aurora Mini-Clock. Made with a Chrome Table Lamp, 126 commom cathode RGB LEDs, and seven segment displays. The circuit and the firmware is based on my Aurora mini 18.
The spherical chrome bowl complements the Aurora design very well. Great work!
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.
