SunbeamTech Light-Bus & Laser LEDs Review

Modding/Small Mods by SidneyWong @ 2005-02-02

When the loud noise of your water cooling radiator fan rig or high performance heatsink fan bothers you a lot, the fan controller (rheostat) will come to the rescue. When your modded case does not have enough lighting or too much lighting, Sunbeamtech has the Light-Bus for you. In fact, this Light-Bus serves a dual purpose duty in controlling the fans and light intensity plus more.

Light Bus Installation

Light Bus Installation :

What could be better than using a Sunbeamtech case I said to myself to ensure fitness? Before I begin, I "dressed up" the wirings and marked the connectors (there is no identification marking on the connector, which does not make your connection hook-up later on any easier.)

With this done, I proceeded to the next "minor" problem.

The Transformer case has a non- removable tray and it uses screw less rails. Therefore, there are no screw holes provisions to mount the Light Bus. The CD Rom rails do not fit the half size frame. The solution is to relocate one of the CD Rom rail pin from the back to the front as photo shown.

And here is the finished product installed:

Connecting to the CCFL converter, fan (you must use 4-pin Molex as the 3-pin connectors provided do not have the speed sensor wire) and HDD light was a breeze. Until, yes until you come to the Y-cord male/female mini sound jack you will find there is no PCI slot through hole provision. For testing this function, I left the side panel open. The installation is quite easy. I connect the mini jack male to the sound output on the back panel, and connect one of the speaker jacks to the female side.

Here is the trick, push the "Sound" button and adjust the "Volume control knob on the panel" after you turn on to some good music until you see the light flashing. You may have to turn the sound volume of your speaker higher to get the feel. But, remember to push the "ON' button on the channel that is hooked up to Fan, otherwise the fan will be "flashing" with the music. Flashing means high/low voltage feed. Hooking up to the Mic is the second option. This may sound complicated, you will get use to it after a few minutes or tries.

Okay, the sound thingy works but to get the effect it requires high sound volume; a bit higher than I like.

As for HDD light function, I can't say it is to my liking as the flashing panel LED is very subdue. Instead, I connected another CCFL to make a big and bright flashing "sign" corresponding to HDD activity.

Installation is the fun part I always say... it is the process that counts, right??

Let's go on to the Laser LED ->
