We were looking at this mature egg under our Bausch & Lomb microscope with the children during home-school science, when we broke for lunch.

We raised this caterpillar, feeding it milkweed leaves until it went into chrysalis, about 12 days later.
Pepper went into chrysalis and emerged after 14 days in May, 2019 and was sent off, into our garden, with much celebratory fanfare and l...

Bedini SSG Fixes Lithium Ion laptop battery

My Bedini SSG used to fix a dead Li-Ion laptop battery. You have to bypass the charge controlling circuitry by prying open the case and making direct contact with the cells inside. I used small square neo magnets to connect them. Use a volt meter to determine the polarity.
