Gadget Freak Case #192: The Ultimate Wireless Volume Control
Andrew Morris decided the usual wireless volume controls donít 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.
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.
