Gadget Freak Case #192: The Ultimate Wireless Volume Control

Andrew Morris decided the usual wireless volume controls don’t offer enough functionality, so he created the ultimate volume control that connects between a computer or MP3 player and an amplified speaker system.

I plan to build this for the High Sclool events where the auditorium volume is never just right.  I will be able to trim the volume while standing at the back of the auditorium where I can hear the true room sound.

I usually hack existing equipment to get what I need and I fully understand his penciled layout / wiring diagram.  Looks like the ones I make.

Did you build it? Please let me know how it went. I built a second one and I use them every day.

I can tell you where to get the non-Allied parts.

Contact me for a minor bug fix to the remote decoder PIC ASM code in Gadget Freak Case # 192, the remote volume control. The BITST subroutine was rewritten for better noise immunity. Alternatively, you can get the updated BITST subroutine from the remote fan control in Gadget Freak Case #198. Don't use the whole program, as it will slow down the volume control response. 

Alternate sources for the remote control to be hacked up:

Home Depot           Westek Model # RFK306LC   Store SKU # 567861

Home Depot           Home Accents Holiday Model # RC-009A-1   Store SKU # 202620 (Same as above units, but has two outlets).
