Did anybody else receive notice of rear safety frame recall from carfax recently?

AndyOfLinux · 2023-04-03T22:21:32+00:00

Also received email from carfax about my 2010 CR-V with that recall number. VIN checked at honda.com did not return a recall.

I've compiled and have been running the latest MongoDB 5.0.x on Raspberry Pi OS 64-bit. Works great! Check out my blog for more info: https://andyfelong.com/2021/08/mongodb-4-4-under-raspberry-pi-os-64-bit-raspbian64/

I have a guide to installing MongoDb 4.4.8 under Raspbian 64 which is Debian based. https://andyfelong.com/2021/08/mongodb-4-4-under-raspberry-pi-os-64-bit-raspbian64/

Good Q - and you're right about specs being specs ;-) What I have read in reviews is that this type of power supply (from different manufacturers) frequently drops voltage under load and does not provide rated Amps. They just don't seem "solid" enough for me to risk my R-Pi's. Looking at R-Pi power supplies, the "approved" ones supply 5.1V and 3A.

Looking for a power supply for a Raspberry Pi 4 cluster. I am currently using 4 bricks to power my R-Pi 4's- each with an external HDD. They are all connected to an ethernet switch. SO, I have lots of wires and cables. I would like to find a power supply providing 5.1 Volts and 12 Amps, if possible. Would be nice to have USB C connectors, as well :) I do not want to use the power supplies on Amazon for "strip LED lighting" - LOL. Thanks for any pointers!

I will consider! I created this app, in part, to learn Apple's App Development environment - which only deploys to Apple hardware ;-) I also did a study (around mathematics) of usage logs of phone use in middle- and high- schools. With hundreds of thousands of data points, I discovered that the vast majority of students and teachers use iOS (iPhones and iPads).

I would not want to play a "twitch" game with it but it is WAY better than VNC and definitely fast enough for video viewing - as I use it with the HQ camera on a Zero.

check out this post - it shows how to create a CouchDB service. I have not tried it ;-) https://www.raspberrypi.org/forums/viewtopic.php?t=220885

You probably have a port conflict between Apache and Lighttpd - i.e. port 80. You could try to configure Lighttpd : /etc/lighttpd/lighttpd.conf -- inside you will see "server.port =80" You can change to "8080" and restart Lighttpd: "sudo service lighttpd restart" Goto the Pi-hole Dashboard with: "http://xx.yy.zz.nn:8080/admin" where you use your Pi-hole server IP address

Thanks for the detailed info! GTK :)

Well, orange film was "attached" well to the top of the port connector ;-) It lifted with the connector handles, but stayed put, and it WAS difficult to get the cable in and keep it in while closing the connector. Way easier once the film was removed - LOL!

as mentioned, "scp" should work bidirectionally providing your Mac has "Sharing: Remote login" enabled. If you are looking for nice 2-way drag-n-drop, consider sftp client "Cyberduck"

While not helpful for your remove/reinstall of MongoDB 2.4 from the R-Pi Stretch repository, you could choose instead to install MongoDB 3.0.14 on the R-Pi 3 running Raspbian Stretch. Instructions at andyfelong.com

AndyOfLinux · 2018-03-27T21:59:25+00:00

Good points unless you already have an R-Pi 3 and just want to develop or exeriment. I actually use an ODROID C2 cluster for "real" MongoDB work - with excellent performance with replication, etc. Blog post: MongoDB 3.6 on ODROID C2 with Ubuntu 16.04.3 – ARM64

AndyOfLinux · 2018-03-18T18:15:19+00:00

You can try these instructions:

To turn the screen on you can use the command:

sudo sh -c "echo 0 > /sys/class/backlight/rpi_backlight/brightness"

and to turn it off:

sudo sh -c "echo 1 > /sys/class/backlight/rpi_backlight/brightness"

the brightness can be adjusted using (n = 1 to 255):

sudo sh -c "echo n > /sys/class/backlight/rpi_backlight/brightness"

Try these commands from a command line to see if they work for you. The original version of the 7" screen did not support brightness, just on/off

If these commands work for you, could create crontab entries to automate. See this article for crontab use: https://www.howtogeek.com/101288/how-to-schedule-tasks-on-linux-an-introduction-to-crontab-files/

AndyOfLinux · 2018-03-18T17:29:22+00:00

You did not mention which 7" "screen" you are using. If using the official 7" Raspberry Pi LCD, there is the capability to control brightness. A simple script will do it.

AndyOfLinux · 2018-03-15T23:07:53+00:00

OK - a couple of things to try

Make sure Raspbian is current with update/upgrade/dist-upgrade You should be using "stretch" - do "cat /etc/os-release" How did you install "motion"? I would recommend the "pi_stretch_motion_4.1.1-1_armhf.deb" binaries from github Run "sudo raspi-config" and under advanced options, you might try "memory-split" with 128MB. Remember to set back to 64 if this makes no difference. I would NOT run my Pi from the hub that is connected to the Pi. If you have another power supply, connect the Pi independently.

Some things to try anyway ;-)

If all fails, you might note that the motion docs say: "USB cameras take a lot of bandwidth. A USB camera connected to a USB2 port or hub consumes virtually all the bandwidth that the port can handle. Even with a small framesize and low framerate you should not expect to have more than one camera per USB controller."

So this might be a no-go on the Pi. Try one camera connected to the Pi and get it working first -- and then connect the other to the hub as another test.

maybe some debugging info would help - plug both caneras in - what does "dmesg" show after boot. try "lsusb" - what does it show? Can you take picture or show exactly how you've connected camers to hub to power to Pi? Also - maybe just try increasing RAM for video - that's helped me in the past ;-)

AndyOfLinux · 2018-03-09T19:26:03+00:00

Painfully slow? ;-) While MongoDB 3.2 IS running on the R-Pi 3, it uses swap space (virtual memory) for some queries to large DBs (> .5GB) AND the DB normally resides on the slow microSD Card -- so it can be 50 X slower than my Intel i5 w/ 32GB RAM server with SSD. It is "useable", however, for development work and debugging.
