Your AGM battery may be OK. I bought one for my riding mower 8 years ago. My electronic tester said it had a lot more cold cranking amps than advertised. It calculated this by measuring internal resistance. As if it hasn't aged in 8 years, it still shows that low internal resistance. However...

I think it was staged. Even if somehow he didn't know the ladder would slide with almost no weight on the feet, it was in his way, he had no place to hang his bucket, and he'd have no hand hold if he stood. He was crouching with his feet 6 feet off the ground, so it wasn't much of a fall. They...

More than a decade ago I was using my first one to monitor the charging of a truck battery. Fair weather was forecast, but the hood was open only 3 inches in case a thunderstorm popped up. One did. Somehow, enough rain blew under the hood that the Kill-A-Watt would no longer show the accumulated...

AFCI. The US NEC has required it since 1999. Traditionally, a circuit breaker or fuse would tolerate a surge, such as starting a motor. Deadly fires were starting from arcing that wasn't sustained enough to rouse a circuit breaker. My refrigerator compressor starts out using something like 140...

If a dryer needed a 20 amp circuit, it would have to have a plug like the one below. If it has a regular plug (parallel blades), it'll run on a 15 amp circuit. (If 20 A is recommended for bathrooms, it's to let you use something drawing up to 5 A while your hair dryer is drawing 15 A.) I...

"Hey, farmer, doesn't this hill ever end?" "This ain't no hill. The back wheel has come off your bicycle."

Sitting or kneeling on a steep, abrasive roof without a pad is hard on pants. About 15 years ago I bought a pair of Open Trails jeans on impulse. That's a discount store brand. I assumed they were of poor quality, but wearing them out would save real pants. I've worn them on countless hours of...

In school, I’d scratch up the money to buy Dickies. They were durable, wrinkle-free, loose enough to be comfortable in winter and summer, and stain-resistant. They were the kind the legendary Maytag Repairman would wear. In the 1950s, new jeans had an odor I found heavenly. Whatever the...

$5 for a 1ma movement. A zener to set where it will read 0. A resistor to determine full scale. Maybe the only problem if it got wet would be the paper scale you draw. So treat the paper with airplane dope, or fix it with a connector and temporary handlebar clips so you can pocket it in the...

IIRC, the guy who recommended LPS-1 had used it in the Air Force. I checked with the manufacturer: 5 years in aerosol, 10 years in bulk. I've had mine nearly 3 years on a shelf in a cupboard. In the past, the propellant in an aerosol can has sometimes apparently seeped out. Maybe some cans seal...

Years ago on another e-bike forum I read about LPS-1 greaseless lubricant. The poster said it excelled at dissolving corrosion. It displaces moisture and leaves a film that doesn't pick up dust. Three suggested uses are circuit breakers, electrical connectors, and electric motors. I bought an...

We had a mast on the roof with 3 antennae aimed at 4 Boston, 3 Burlington, and 9 Plattsburgh, all very snowy. Three 300-ohm leads came down to a switch on the back of the TV. I never saw the Collins Kids. Their show was live at 10 PM Saturday night in Los Angeles and it wasn't taped, but some...

St. Johns had lots of brands, and they all tasted the same. Elsinore reminded me of the St. Johns brewery, up on a hill. The didn't talk like Bob and Doug. They sounded Scottish and Irish.

I believe the grooves in tires sold in the Great White North are to channel mice.

Remember the hot rods of the 1950s? A hot rod wasn't built from scratch or from a kit. Its purpose wasn't necessarily to win races or shows. A hot rod was a modified old vehicle, but many who drove them could have bought new vehicles. The new-car market was about fashion. A hot rodder wanted...

About 25 years ago I bought a Bell floor pump for maybe $15. I'd say it was made to function well and to last. The hassle was the lack of a gauge. I'd stand to pump, get down to check pressure, and stand back up to pump. I don't remember seeing a floor pump with a gauge what was likely to be...

They remind me of boots I got at REI in Seattle in 1975. Light and tough and durable and kept my feet dry.

Adidas may market your shoes as bike shoes, but Sheldon Brown doesn’t mention any kind of bike shoes except the ones mechanically fixed to the pedals. He says the beauty of plain pedals is that you don’t need bike shoes. He says open-cage plain pedals like yours should be used with stiff...

Confused? As I stated, I reported what Wikipedia said. All have stiff soles and cleats. https://en.wikipedia.org/wiki/Cycling_shoe I believe stiff soles are like low bars. Low bars are good for reducing air drag if you want to pedal yourself as fast as possible and for flipping a bike back and...
