It turns out you can buy little cubes of various elements from sketchy Amazon marketplace vendors.

Naturally, I wanted some Tungsten, because of its incredible density.

I cannot emphasize how much I love Josh Fruhlinger’s Comics Curmudgeon blog.

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.
