Experiments

Slylock Fox is one of those bogus “kid’s fun” things that appear in the Sunday Funnies. Slylock is kind of dumb, but it’s better than Uncle Art’s Funland, which is basically a store-brand Sunday funnies strip.

I blew out another LED on my wireless charger detector. So I modified it to be simpler, and more interesting.

I rebuilt my original astable multivibrator with the 2N3904, transistors, better matched capacitors and 10K and 68K Ω resistors from the improved astable multivibrator I wanted to see if that made a difference in the original circuit’s behavior.

I built an “improved” astable multivibrator circuit from:

IMPROVED ASTABLE MULTIVIBRATOR, by RAJU BADDI, National Center for Radio Astrophysics, TIFR, Ganeshkhind P.O Bag 3, Pune University Campus, PUNE 411007, Maharashtra, INDIA; baddi@ncra.tifr.res.in

Here’s the schematic of the improved circuit:

I built an astable multivibrator from discrete components:

I used 2N2222 transistors instead of BCS547.

In an attempt to gain some electronics knowledge, I bought $30 worth of components and breadboards from Amazon, and built a 2-transistor LED flasher.

I took this picture 2022-11-24T08:45:00-07:00. It confirms that the unusual arrangement of snow found in the Mystery of the Melted Snow wasn’t a one-off.

I looked out at my backyard early in the morning of November 5th. It had snowed the morning of November 4, but the sun came out that afternoon, melting most of the snow. This is the weird arrangement of snow that I saw.

I dropped my cell phone and cracked the screen, so I got a Google Pixel 6 and a wireless charging stand. I ended up looking up the “Qi” standard for these chargers. It seemed like the coils used to transfer energy weren’t particularly exotic in size, shape, material or manufacture, so I decided to try to receive some energy from the charging stand.

I’ve since revised this contraption.
