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.

Firefox Video Speed Controller

Today I installed the Video Speed Controller for Firefox. Let’s see how this goes!

These are the controls:

  • S – decrease playback speed.
  • D – increase playback speed.
  • R – reset playback speed.
  • Z – rewind video by 10 seconds.
  • X – advance video by 10 seconds.
  • V – show/hide controller.

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!

In this video I unbox my new Kingston FURY Beast White 128GB (4x32GB) 5600MT/s CL40 DDR5 XMP DIMM | Overclocking | Plug N Play | Intel XMP 3.0 | Kit of 4 | KF556C40BWK4-128.

This is the replacement RAM I ordered after the Corsair RAM debacle (wherein they sold me scrap metal, not RAM, really, you wouldn’t dream of it!)

You can read about Kingston FURY Beast DDR5 Memory and find the KF556C40BWK4-128 specs (PDF). There is also warranty information and memory installation instructions.

You can learn more about memory timings, particularly CAS Latency.

Today I managed to double the RAM in ‘charisma‘ from 64GB to 128GB and also double the RAM in ‘treat‘ from 16GB to 32GB. A productive day!
