Where did you get 270?

Looks to me that both report 108.

Possibly, the intent was this (?):

Reading on page 49, under the heading "A secure key",

"With Raspbian, you have a pair of keys (public and private) in /etc/ssh/. Unfortunately, they’ll be the same as those held by everyone else with a copy of the Raspbian image that you ~~downloaded.~~ cloned"

The SDCard formatter didn't find any issues either?

That's interesting. I'm really curious of the exact nature of this card's failure.

lpsw

Sounds to me like you had a bad SD card, and makes me wonder about how Etcher does it's sanity check. If you tick the box for Etcher to verify the card, it checksums it and compares the checksum against on created while it was writing the unzipped image file. That's what the last 5 minutes of the p...

Your SD card may be full, corrupted, or has failed.

Ah, I see, your code tweak was to add that awb algorithm to the available list in the 'Camera params' ... 'White balance' menu ? Correct I added your modification to the ~/pikrellcam/src/config.c file, then ran make on it. it does not seem to make a difference to the version of pikrellcam that is r...

Is this to fix the purple screen issue?

To be precise, my change was to add support for the new awb algorithm (greyworld).

lpsw

Have you tried searching this forum?
I think you may find some info.

lpsw

The Pi can't see the camera ("detected 0").
Have you verified that both ends of the camera cable, as well as the SUNNY connector, are inserted and seated correctly?

Big fuss about nothing,

Amen, 'nuff said.

Being rather anal here...

Not sure why this was posted on the Python forum.
Are you calling raspistill from Picamera?

What is the response from:

Code: Select all

sudo vcgencmd get_camera

Can you post the contents of /boot/config.sys?

Edit for clarity

lpsw

In ~/pikrellcam/src/config.c, append the following line to the end of awb_mode_table (found around line 117): { MMAL_PARAM_AWBMODE_GREYWORLD, "greyworld" } I have an error on make when I did this... config.c:129:2: error: expected ‘}’ before ‘{’ token { MMAL_PARAM_AWBMODE_GREYWORLD, "greyworld" } ^...

There was also this

PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

Can you successfully ping to 8.8.8.8?

lpsw

It looks like a DNS problem. The output from timedatectl shows not synced. No return from the google.com ping. All symptoms of DNS not working correctly. You might post the last 15 or so lines of /etc/dhcpcd.conf if you are using a static IP. If you are using dhcp then: cat /var/run/dnsmasq/resolv....

fantastic, thank you pcmanbob! I'll try with raspbian and see what happens. any takers on the cooling ? how do you guys keep your RPI ? case ? no case ? heatsinks ? aftermarkets with or without fans ? It depends on what you're planning to use it for, and what you plan to connect to it: Pi Camera (v...

One way is to check your router's active associated MAC addresses vs. MAC addresses assigned to your interfaces.
Assuming nothing is connected to the ethernet port, if you disable the onboard wifi (per above) then your USB adapter is the point of WIFI connection.

Edit: for brevity

From my Pi3b+ config.sys (some for future reference)

Code: Select all

# Optionally disable wifi/bt
dtoverlay=pi3-disable-wifi
#dtoverlay=pi3-disable-bt

What Heater said.
Just sell them.
Better yet, donate them to a school.

B.Goode beat me to this:

Maybe your son is now old enough to get it running himself if you point him at the advice published by Raspberry Pi

That's great advice, ascender89. He will learn a lot from the bringup of his Pi (see my sig

IMO, a 3B+ is overkill, if it's only task is to monitor the garage door. A Pi0WH (with headers installed, so no soldering) will suffice. I monitor my entry doors with Pi0Ws + Pi Cameras + Pikrellcam. Works great. Your use case will probably use much less CPU and memory than mine. Are you doing this...
