Core power handling Capability
I have some Flyback transformers (from CoilCraft) these were originally intended for use in a 70W 60kHz application using the NCP1200. If I increase the switching frequency to 100kHz is it reasonable to expect 90-100W using the same core? I've been running simulations and the rms and peak current for 100kHz equa... 26 Apr 2010 12:37

Replacing floppy
I have an old keyboard that uses floppy to hold its os. It takes about 3 mins to fully load if that. Also the disk can become corrupt overtime. I was thinking of replacing the floppy with a ssd type of system. What I'm thinking is possible is to "hijack" the floppy interface cable and simulate a floppy disk bu... 1 May 2010 13:11

We started with Vishay parts and through at least 3 cost reduction effort have found that production parts are never the same as approval samples from the lower priced competitors. ... 26 Apr 2010 05:52

Ocean County NJ Family-Law and Cyber-Law Lawyer Charles Novins Continues To Defend Against Net Abusers
More Usenet posters have addressed Charles Novins publicly, while joining in the Toms River, New Jersey attorney's campaign to clean up the internet, and more-specifically, Usenet. One poster was a years-long veteran of the group, "alt.usenet.kooks," which had become home to bizarre, irrational, and hate-laden... 24 Apr 2010 08:18

LM13700 weirdness
I'm using an LM13700 as a VCA in a 9V battery powered circuit, using an opamp buffered virtual ground. The circuit works fine when powered off the battery, but I wanted to test it using different supply voltages. When I hooked up the supply to the 15 volt breaboard power supply, I noticed that the LM13700 was ... 26 Apr 2010 19:30
