Each time I watch something with Chris Hinshaw of Aerobic Capacity I learn something new. Brute Strength had him on their podcast again for a great episode. There is some good stuff about lactate in this one.
You may recall that my Thruster Attack program is based on Chris’s work.
The girls were having some problems with the LEDs in a couple of stuffed bears. Mom thought there might be a short in the wiring because they’d work for 10-15 seconds and then the LED sequence would freeze up or turn off. Before tearing into the bears I got out my multimeter (has become quite the handy dandy tool for me) and tested the batteries, which had been straight out of a package when they were used in the bears.
Two of the AA batteries were reading right around the expected 1.5v, but the other was -0.3v, as shown above. I’ve never seen that before, so I did some Googling.
Any type of battery can and will begin to charge a dead cell in reverse if you keep trying to draw current out of it. Remember, a battery is a series connection of cells, so in any pack regardless of chemistry, a dead cell once depleted is going to be subjected to voltage reversal.

It looks like something happened to reverse the polarity during manufacturing or the battery was DOA and got charged in reverse from the other two AAs.
After replacing the batteries all of the bears work again. It’s a good reminder to check your power source when things don’t work.
My 6-year-old niece Kennedy got me hooked on this game. She plays it all the time on my Mom’s iPad. All it took was her beating me for me to install it on my phone. I wish there was an upgrade for me to pay to get rid of ads though.
My Mom, my sister, and I worked on it over the course of 4 days.
Kennedy and I made a wire loop game, using some basic cheap electronics.
The initial wiring and cutting of the box took more time than I figured and she started to lose interest until we got around to the top. We did this all on-the-fly, but there are plenty of tutorials (like one on Instructables) you can follow.
We customized this Tripoley board to be more like the Michigan Rummy we had as kids. Over twenty years later we finally doubled the stakes from playing for pennies to 2¢. Almost 20 rolls of pennies are in play. It’s a high stakes game!
My Dad shot a huge 560 pound bear in Manitoba earlier this year. Last night we created this movie from the videos captured on his bow camera. Due to cropping for stabilization and watermark removal it’s hard to tell he was as close as 5-10 yards from the smaller bear and probably 15 yards away […]
