Network Switch
  • I bought all the gear to do 10gbe but ultimately went back to 1gig simply because the power consumption. The switch alone used 20w at idle and each NIC burned 8w and I couldn't justify it.

  • PhotoPrism vs Apple Photos currently?
  • So you have photoprism pointed to a folder but you push photos into the folder witb syncthing. How do you trigger the re-index or its somehow automatic? I run my photoprism in docker and I always had to manually trigger the index after changes to the folder.

  • PhotoPrism vs Apple Photos currently?
  • As someone who has and still used photoprism for over two years and donated heavily...steer clear. Their update cycle is slow and the things they keep adding don't seem helpful. Still no multi-user support. If you don't upload new photos via photoprism using WebDAV you have to make your own scripts to watch for changes and refresh which took a lot of time for me to setup.

    I'm just going to start using Nextcloud and Memories app going forward.

  • Light switch advice
  • Install Enocean wireless, battery free switches. I've used them for many years, they work awsome. The switches can go anywhere you want (double side tape on any surface) or screw in as normal light switches. The act of pushing the button generates enough energy to send the RF signal to a receiver you install with the light and its powered from AC mains.

  • Help! All plants stalling/slow growing
  • Those leaves look too light green, the plant is stressed. How often do you water the plant and how much do you give it? What is your metric for 'enough'? Do you let water sit in that tray? I would just start by watering it 1/3 as much as you currently do and see how it goes, the leaves will wilt if you are stressing it due to lack of water but in my experience cannabis can handle serious drought stress, they're champs.

  • Help! All plants stalling/slow growing
  • Just a heads up I grow mostly vegetables, have been an avid gardener for over 15 years so my advice will be generic and not specific to growing cannabis. In general I think cannabis growers over think something that is much simpler than it seems. After growing veggies for so long, I found that cannabis is so laughably easy to grow, its ridiculously robust, will handle all kinds of abuse and grows incredibly fast. Here is the little beast I grew two years ago

    You mentioned you put them outside, how long ago? Did you re-pot them when you put them outside? They will need time to establish bigger roots when you replant them. Are you growing anything else outside that is doing well or just the cannabis? A picture of the leaves will tell a better story, green has lots of shades and a light green means stress. If you gave it lots of nutrients and you got no response that is bad, either you will over feed it and stress it out (Very hard in my experience) or it will take it up and burst into growth. What this tells me is your plant CANT take up the feed in the soil because the dirt is too wet. How often do you water the plant and do you check the soil to ensure its dry before watering? Has it rained a lot? Over-watered dirt will kill your plant because it cannot get the nutrients it needs, it needs to be damp but NOT wet or the roots aren't effective.

    Android Microphone Snooping

    So I had a verbal conversation with a coworker yesterday and now I'm getting fed very specific ads. No possible way it's accidental. I have most of the microphone access to apps limited, I have Google assistant turned off and no VPA setup in my home. I use a Oneplus 9 pro, does anyone have recommendations on how to further root cause this or just par for the course for using any standard android OS? Have other folks had similar experience after locking down their stock phones?

    Pi Powered Cuckoo Clock

    Action Video

    For her birthday my daughter received a cuckoo clock. It had very limited programming for 'quiet hours' so I fiddled with it and ended up breaking it. I didn't want to disappoint her so I gutted it and proceeded to install a Pi Zero W and a headphone amplifier I had built. She now has a fully programmable, USB powered, linux based cuckoo clock where I can program it to whatever suites our needs and it syncs it's time with NTP severs. I even connected her night light to it which turns on at night and off to let her know when its time to get out of bed. This combination also allows us to have dance parties with flashing lights, a dancing bird and fun songs coming out of her cuckoo clock. It's ridiculous and eccentric but it makes us happy!

    Build

    • The Pi Zero's dont come with a sound output so I built an audio output filter to convert the PWM output to an analog audio output
    • Connected the analog out to a OPA1642 based headphone amplifier I designed and built
    • Wired up the cuckoo bird's coil actuator to a simple MOSFET drive circuit to control it from the Pi's weak GPIO output
    • Wired up some 5V string lights (used to be battery powered) to a simple MOSFET driver circuit to control it from the Pi's 3.3V GPIO output
    • Wrote some bash code to make the bird dance, the light flash and the cuckoo bird sounds play
    • All the scheduling and execution of the code is done clean and simple in crontab
    • I also have a text to speech engine verbally state the hour after the cuckoo action so my daughter can better learn to tell time by herself

    To re-map the audio to the PWM0 output of the Pi

    add to /boot/config.txt to remap the audio to the PWM0 and PWM1 pins of the pi.

    ```

    Enable audio (loads snd_bcm2835)

    dtparam=audio=on #remaps the audio to the PWM0 and PWM1 pins (pins 18 and 13) dtoverlay=audremap,pins_18_19 ```

    Code

    Cron Scheduling

    ``` @reboot /home/pi/startup.sh

    #cuckoo between 8am and 6pm, inclusive 0 8-18 * * * /home/pi/cuckoo.sh

    #turn on the night light at 6:15 pm 15 18 * * * echo "1" > /sys/class/gpio/gpio26/value #turn off the night light at 6:15 am 15 6 * * * echo "0" > /sys/class/gpio/gpio26/value ```

    Startup Configuration for GPIO

    ```bash #!/bin/bash

    #setup the GPIO #"In order to use a GPIO pin through sysfs, we first have to “export” each one to make the appropriate paths available." echo "17" > /sys/class/gpio/export echo "26" > /sys/class/gpio/export #set direction echo "out" > /sys/class/gpio/gpio17/direction #cuckoo movement echo "out" > /sys/class/gpio/gpio26/direction #nightlight ```

    Flashing Light Code

    ```bash #!/bin/bash

    i=1

    while [ "$i" -le 3 ]; do #turning the GPIO on echo "1" > /sys/class/gpio/gpio26/value sleep 0.050 echo "0" > /sys/class/gpio/gpio26/value sleep 0.050 i=$((i + 1)) done ```

    Cuckoo Code

    ```bash #!/bin/bash i=1 echo "Looping "$(date +%I)" times"

    while [ "$i" -le "$(date +%I)" ]; do aplay /home/pi/cuckoo.wav & #flash the lights three times quickly /home/pi/flash.sh & #turn on the cuckoo bird coil to make it bob down and flaps its wings echo "1" > /sys/class/gpio/gpio17/value sleep 0.300 #turn off the cuckoo bird coil so it sits back down echo "0" > /sys/class/gpio/gpio17/value sleep 0.700 i=$((i + 1)) done #Text to speech engine, speaks the current hour through the speaker #date + sed command below returns the hour, in 12 format, and the sed command removes the leading zeros espeak -v mb-en1 -s 120 "it is $(date +%I | sed 's/^0*//') oh clock" ```

    Title says most of it. Spin electric scooters exited the Seattle market and abandoned their scooters all over the city and apparently they have a pi 4 in them!

    Ghost Pi - an unconventional backup solution

    I call this nonsense host ‘Ghost’, for me it’s similar to a tape backup solution. Fairly simple concept, it’s an old Pi1 + external mechanical drive that sits dormant with its ethernet off. Once a month, at a random time and random date it enables the ethernet, spins up the drive and pulls data from the main server to update its drive then goes black until next month. The only way to check or maintain the pi is a push button that toggles the ethernet interface. I slapped it together with some scrap wood, spare hardware and screwed it to a 2x4 in a dark corner of my basement. It’s my 5th string backup, the ultimate insurance policy because I’m mental.
