Re: Dielectric Absorption

At t=114 days we are at 1.27V.

Re: Classic Bead Tantalum Capacitor Failure

I had an unfused Tantalum burn a 1" charred hole about 30 years ago in a PCM3324 card.
It was unrepairable.
I'm glad Sony decided to replace it for free.

Aren't most modern SMT Tantalums fused?
The one in the Sony was a Kemet and wasn't fused.

Classic Bead Tantalum Capacitor Failure

I could tell by smell and the burnt look which cap in the new plugin it was. Today, about 10 years later, I realized I should have changed the two in the ...

Re: Residential Lighting with LEDs: Retrofitting the Pink Ranch

Finally got around to replacing the last 3 CFLs in the house. There was one left in the attic - at the far end of course - and two in the basement also at the far end. The basement ones required crawling - they're work lights. I hadn't been looking forward to that walk down the attic catwalk or craw...

Re: Entropy

A pint a week? My A/C probably gives that off in 5 minutes on a good day. Too bad the Peltier is so inefficient. This week's quick repairs included a new mower wheel and replacing the circuit board in a remote thermometer. The mower wheel had just worn out. The thermometer, only a few months old, ju...

Re: zevo bug light trap (fail)

I'm inspired to plug in the "old-school" blue ultraviolet florescent bug zapper I have in the garage.

It looks so cool, not as cool as a lava lamp but the bug zapper is more of a summer thing.
