Raspberry Pi

I had a hard time with my raspberry pi zero w after I got it up and running, and had to search many websites to figure things out. Here I will go over these items to have them handy in the future when I forget it all. Connect to multiple wireless networks with a Raspberry Pi I needed my pi to connect to multiple networks while I was working on it, and finally got it figured out with the site above. In a nutshell: NOTE: The pi won’t connect to 5 GHz wireless networks, only the 2.5 GHz. As of this writing anyway… The OS uses the /etc/wpa_supplicant/wpa_supplicant.conf file to manage wireless networks. You need to add extra networks as above. Name the different networks to something that makes sense to you (“home” and “dad” in the example above) with the addition of the id_str=”name” string.  (I am unsure whether you can use another variable name other than id_str, so stick with it.) You also need to edit the /etc/network/interfaces file. This basically allows you to point to the new network names you designated. Insert pic here. If your file is different (mine was) just take this verbatim while changing names to what you designated in the wpa_supplicant.conf file. The link page explains it more in detail, but this is a nutshell and more information would spill out. Raspberry Pi Servo Jitter I wanted to run a tiny servo with the Pi, but found the way I set it up initially was too jerky to be of use. It comes from the Pi not really being meant to control servos. NOTE: You run pigpio via python scripts. Do you know python? I don’t. I found with further research that using pigpio was the answer for smooth servo action run by the Pi.  The caveat is that it is best for small 9 gram servos and likely only one. So the nutshell is… Install pigpio on the Pi via command line: sudo apt-get update (to update the Pi to latest repositories) sudo apt-get install python3-pigpio sudo systemctl enable pigpiod (to set the pigpio daemon to auto start on boot if appropriate) OR sudo pigpiod (to run the daemon manually) Raspberry Pi pinout Pigpio uses the GPIO or Broadcom numbering instead of the physical numbering of the pin outs. For example in my case, I was using physical pin out 11, but the GPIO number was 17. It caused some consternation when the scripts didn’t work at first. how-to-run-pigpiod-on-boot A minimal kiosk mode for a Raspberry Pi

The first amendment

The family made me stop asking house guests if they would like to take the dog(s) home, for keeps.  I feel there is a first amendment issue here…

Favorite sermon quote

This was in the old blog that got eaten and is from 2012.

“Look at the tiny mustard seed, which grows into the mighty oak!”

Cute things the children say

Back in 2011 I wrote this, and it being earth shattering in importance, I’m doing it again.  You’re welcome.

I keep forgetting the cute things the children say, so for posterity here they are:

“Lets play hide and seek.  You hide there…”

“What should we name your new little brother?”
“Little Horsey or Barney.”

“What bowl do you want?”
“The black one. Food tastes better in a black bowl.”

The burbible or comberbible (for the convertible)
“Say goodnight to the boys”, “Night the boys”
Bwick (brick)
Tookie Monner (Cookie Monster)

New for 2020, cute things I (the Dad) say:

“Do you know what time it is? It’s dark o’clock. Time for bed!”
After the kids play D&D: “Did you win?”
After the kids play Minecraft: “Did you win?”
“Dad, I’m hungry.” “Hi Hungry, I’m your father.”

Soooooooo… A WordPress update ate all my amazing prose

A wordpress update ate up my Shakespeare level prose, depriving the world of my wit and amazing intellect.  AGAIN.

I’m so sorry for your loss, but I’ll do what I can to make it up to you.  You, yes you, especially you.  I do it all for you.
