Andy, thanks for those: he hasn't gotten to the project yet so those options are helpful.

One builder, using his remote volume control (GF case #192) in a commercial setting had trouble from spontaneous volume changes. I made a change that fixed the problem, but slowed down the response of the volume control. While developing another Gadget Freak project, I revisited the remote control system, using a new oscilloscope and saw something I missed before. Using this new information, I rewrote my receiver decoder software to greatly improve speed and noise immunity.

The volume control and this fan control use the same receiver decoder software. Also, there is an issue with the older RF receiver module. Make sure that the receiver module in the remote control you hack up is a small square PCB, about the size of a postage stamp.

If you don't have the means to program a PIC yourself, give me your mailing address and the "channel" your remote is on, and I will send you a PIC programmed with the updated software. If your "channel" is something other than A B C or D, then I will need to know which jumpers are cut in the transmitter or the discarded receiver unit.  If you can program a PIC yourself, tell me so and I will email you the updated software.
