Bits and bobs related to Wireless-Tag's WT32-ETH01 board

Unofficial guide to the WT32-ETH01 What is this thing and why would I use it? The WT32-ETH01 is effectively a small, cheap ESP32 development board with Ethernet, WiFi, and GPIO pins, made by a company called "Wireless-Tag" (WT). As of this writing, it's around $15 at JacobsParts and around $7 from AliExpress. There aren't a ton of ESP32 boards with Ethernet, and the WT32-ETH01 is by far the smallest, cheapest, and simplest. (The OLIMEX ESP32-POE and wESP32 are the other notable options.) So,

Cozy Horror Game Grave Seasons Is Stardew Valley Plagued by a Serial Killer

At Summer Game Fest, I tried a game that was bold enough to ask: Why doesn't Stardew Valley have more murder? Grave Seasons, due out next year, is a cozy farming sim with a morbid edge: It's about all the friends (and romantic partners) you make along the bloody way to stopping a serial killer. A little bit into the short demo of Grave Seasons, I took to the fields to clean up the run-down farm I'd broken into and decided to adopt, only to find a severed hand.

The Algebra of an Infinite Grid of Resistors

The Algebra of an Infinite Grid of Resistors In a previous note we discussed the well-known problem of determining the resistance between two nodes of an “infinite” square lattice of resistors. The most common approach is to superimpose two “monopole” solutions, one representing the field for one amp of current entering a given node and flowing “to infinity”, and the other representing the field for one amp of current being withdrawn from a given node flowing in from infinity.
