I’m trying to get my WeAct Studio Epaper Modules to work on my WeAct Studio ESP32-C3FH4 microcontroller. I’ve made some progress, but it’s not working yet.

ESP-NOW instead of WiFi
Today I learned about ESP-NOW over here: Forget WiFi! This Wireless Method is WAY Better?
This looks like exactly what I need for a project I’m planning. I want to connect my WiFi router with a relay between its power source. I can then trip the relay to reboot the router. I need to do this every couple of months and doing it manually is a pain because I have to walk into the other room to do it.

555 timer
One day I intend to Build My Own 555 Timer.
In the recent past I posted How a 555 Works as a Timer which refers to an interesting video on the topic.
In that video the speaker gives us a mnemonic for remembering the transistor schematic symbols. Referring to the direction of the arrow on the symbol the “NPN” transistor “Never Points iN”. Good to know!

Books by Bill Inmon
This is a note for Future John.
I am reading Fundamentals of Data Engineering which says that beside Ralph Kimball, Bill Inmon had a lot to do with data warehousing in the early days. I’m going to try and read a few of his books, many of which are available in Kindle (and Audible) format from Amazon.
Maker’s Schedule, Manager’s Schedule
Over on Rory Sutherland – Are We Now Too Impatient to Be Intelligent? | Nudgestock 2024 the inimitable Rory Sutherland made reference to Maker’s Schedule, Manager’s Schedule by Paul Graham. It’s helpful to be aware of these two types of schedule.
In the same video Mr Sutherland also referred to The Unaccountability Machine: Why Big Systems Make Terrible Decisions – and How The World Lost its Mind which looks like it would be an interesting read.
Oh, and he referred to Social Acceleration: A New Theory of Modernity as well. I don’t think I’m going to spend the money or the time on that one, more’s the pity. I only have one life and can’t do everything I might wish I could.
