Back on the subject of the Write-only memory (WOM), when Signetcis announced the product I sent off for a free sample (yes, thay acutally offered samples of this part!!!). A few days later I received a package containing a chip with the number "25120-N-NFG" on it, a bumper sticker that said "Honk if you're WOMsome, and a pair of plastic sunglasses with a rubber nose and fake bushy eyebrows attached.
Now THAT's the way to roll out a product!
Or how about a 1980's QST magazine april 1st arrticle about injecting DYE in your coax and firing up your transmitter so you can see your yagi antennas pattern.
I had just pulled out some of my moms cloths DYE and was looking in her kitchen cabinets for a way to inject the DYE in the coax feed line when I glanced back and realized what month of QST magzine the article was in.
Of course without saying a word I then quietly put everything away all the time with my mom watching me with the typical expression on her face just about to ask me "what are you up to now?"
Remember when Bob Dobkin announced the Dark-Emitting Arsenide Diode (dead)?
.....or the technical paper that claims that light emitters are actually dark suckers: http://www.rogermwilcox.com/darksucker.html
There's the 70's Wireless World article 'Dynamic Range Versus Ambient Noise' by George Izzard O'Veering, which can be found at:
I also remember a magazine called Elektor which had some spoof circuits in its April editions, like a 'Battery Eliminator', which was a dead short.
