I noticed this thread a little late, but I wanted to comment on chip operation. Looking back at my two-way-radio reapir days in LA, Motorola-designed frequency-generation chips (an entire series of divide-by-n and integrated PLL chips) that were desined to work together in a multi-step scheme. The g...

Why would you want an optocoupled tach in the back of your head?

Some years ago NASA did an experiment where they slowly SPUN a long conductor loop behind the shuttle, thus negating the nifty trig/magnetic math formulas posted peviously. It oh-so-briefly generated a rather large amount of current, dissipated through a dummy load, before the cable broke.<p>I'm sti...

Unfortunately, he's had a sucession of CAD/drafting jobs, one right after another, because of it. He'd last until they got tired of his spelling. One ex-employer actuall...

So, anybody got any really neat electronic circuits taht apply to this National debt?

I've had astounding results with a sound card O-scope since about '95 ( recall at that time refusing to go to W95 because W3.1 was plenty good enough). the O-scope software hadn't come out yet, or I hadn't found it, so I used some audio editing software.<p>Where it worked so well wasn't measuring fr...

Most likely:<p>The end with three pins: the two outers are the coil, the center one is the common for the contacts.<p>the other end, one is NC, the other is NO (normally closed & open).<p>An ohmmeter can verify this in seconds.

IIRC, a Nat'l Radio Club review of the then-new GE SupeRadio II mentioned that a Select-A-tenna did very little for the radio. It went into further detail in that the SAT worked best (and quite well) with radios having poor front ends. The SAT worked equally poorly with other high-quality radios.
