4000 Picofarads
The Sonata passed the 4,000 mile mark on the way to a friend’s house this evening.
A week ago I received a piece of mail from Amazon informing me that they had made it easier to use my accumulated reward points right at the check out page and that I had a whopping $27.61 points available. Donna was feeling expansive, so she said go ahead and spend them. And because I have been such a good boy I could have an extra ten bucks to cover shipping. I really didn’t need anything in that price range and briefly considered a stuffed purple whale for the back deck of the Purple Whale, but instead opted to upgrade my cheapo computer speakers to some slightly more expensive ones – Cyber Acoustics 3 pc Subwoofer/Satellite System.
Last night I installed the speakers. First up was to remove the old set and if your PC setup is anything like mine, it required a trip under the desk to the land of the Dust Bunnies who live under the mountains of Power Strips and Voltage Converters. I sorted through the hanging wires rounding up the ones associated with the old speakers, unplugging here and there until I had the two small satellite speakers, the 3″ cube that passed for a subwoofer and the power plug/converter in a pile in the bottom of the trash can. The new setup went together with little issue and sounds leaps and bounds better than the one it replaced.
This afternoon I needed to recharge some AA batteries so I placed them inside the charger that rests on the right side of my computer desk. I leave the little sucker unplugged because the manual for it said that doing so would increase its lifespan. When I plugged the the connector into the back of it, nothing happened. Hmmm, usually the display fires up so you can monitor the charging process. Thinking I might have dislodged its power converter plug when installing the speakers I returned to the Land of the Dust Bunnies. I followed the wire down to the power strip and, nope, it was plugged in. I unplugged it and looked at the back of it. It read Altec. Uh oh, that was the brand name of the speakers I just took off. So I rooted around in the trash to retrieve the power plug that I had mistakenly thrown away. Hooked up the correct power thingy to the charger and the display was still blank. Dang.
The photo above shows what happens to capacitors* when 9V AC is applied to where 3V DC is supposed to go. So not only am I hard on batteries, their chargers are none to safe around me either.
*I have no clue if these are 4,000 picofarads or not, but when I looked up farad on wikipedia this phrase caught my eye, When speaking of capacitor values a picofarad is sometimes referred to as a “puff” or “pic”, as in “a ten puff capacitor”. Kind of apt as the capacitors in this charger sure went up in a puff of smoke…
