I have a limited supply of laser-cut acrylic case for Color Organ Triple Deluxe II available. This is one time offer, the cases won’t be available again once the supply is gone.
(The case kit does not include the knob.)

Color Organ Triple Deluxe II Acrylic Case : $19.00 Limited Supply Only

Recently purchased T962A reflow oven. There were a couple of issues that I dealt with. Please see the Instructable on what I did.

This is the largest of Maker Faire, so I will be bringing a lot of stuff, some of which are not yet seen by anyone. (yes I’ve been working hard)

Please come see me and hundreds of great makers at this event. It will be exciting!

It’s a very simple design, but very functional. Built with laser cut acrylic and screws and nuts only. No filing, glueing or bending.
You can download the design file, and laser cut 3mm acrylic. I used Ponoko, but you should be able to use any services available.
Use my design as is, or customize as you like.
You will also need four 1 inch, #2-56 machine screws and nuts, such as these.

* The design file is formatted according to Ponoko’s specifications. You might have to modify it if you are using a different service.

Now those who are not into surface mount soldering can build Aurora color organ (or VU meter)!

The circuit is exactly the same as the original surface mount version of 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).

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.)
