Sounds like a job for Arduino or FPGA. I can't help feeling that there ought to be a suitable Mesa module, but Arduino's have PWMs that share a clock, so for suitable thresholds are guaranteed not to overlap. I don't know how smoothly you can change frequency -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!
