I've seen variations of this energy harvesting circuit (from wifi, radio etc...) floating around the web and

C1 and C2 are 0.22uF 100V ceramic

C3 and C4 are 100uF 16V electrolytic

Diodes are general purpose switching, but I've also seen Germanium ones used

I'd add ground at the junction between C3 and C4 for better performance

My mother's best friend took me out to lunch on my 28th birthday and punched a seagull that was trying to take the butter, but this here sounds like a #horror movie.

Today's #linux discovery was the "btop" utility. I particularly like how it shows the cpu temperature 😎

My latest Terrible Keyboard is out, in video form this time (1m39s). It's the CubeKeyboard!

Only Sith deal in absolutes.

Yes, I realize the irony in that statement lol.

What day is it? That's right! Recap day!

Tandy 1400LT Power Supply is going to get every cap replaced.

An interesting experiment, how drivers on the road react differently to a pedestrian and a pedestrian with a brick.

It may be interesting for those who write use cases for #autonomous cars :)

It's itching me to buy this, just to see if it will respond with an http code 418 as is should!

The answer to the question... Vote before reading. 

Now, had I done my homework, the specs page states this clearly. However, I purchased based upon the title alone, expecting all the ports to be gigabit, as it was 2020 afterall... Who still puts 100mbps chips in their devices?

Asus.. That's who.. Then put gigabit in the title for suckers who only read the title.

The answer to the question... Vote before reading. 

A year or two ago, I purchased an Asus RT-AC51U "Dual-Band AC750 WiFi 4-port Gigabit Router with USB device sharing"

The WAN port is 100mbps
The LAN ports are 100mbps
The Wifi is AC750 (WiFi 5 capable of max of about 433mbps)

I purchased this because their page stated it was a gigabit router, and I planned to upgrade my service to gigabit eventually. Which I recently did. I'm enjoying my 100mbps connection still.

For my review of the case, here's what I put in at Newegg. It was $45 shipped, not too bad.
