"This Is The ONLY Home Server You Should Buy" Or, why older computers may be better for the environment | Hardware Haven
  • I love this community, I used to rant about efficiency all the the time on reddits self hosting community and everyone thought I was insane. If the damn thing is going to run 24/7 for 5+ years then put a little thought into its power usage!

    I personally love old Dell optiplex micros on eBay. Cheap, plentiful laptop hardware in a cute little box which allows modest upgrades. My primary server in a full sized case is just a laptop CPU, Ryzen 5600g. It brings me joy that my network has four servers and still is under 75w idle for everything including networking gear.

  • Hosting a Webserver in a RPi Model B… in 2025
  • Ive been using a pi model B for the last four years as a wood stove monitor, data logger and web server for the landing page of said data. Is this a big deal?

  • My dailies
  • +the fact the pi is so darn cheap, has the IO and can emulate the game on the system not at all designed specifically for the task while also running a whole Linux stack and being online. Things have advanced tremendously.

  • How do you think early humans survived without water bottles? Did they just live next to water sources all the time?
  • My wife won't leave the house without several water containers as it she is crossing the god damn Sahara. We live in the North East, its not even dry! I always ask her how she survied childhood without stupid fancy bottles that are marketed. Fortunately she is patient with my crap and loves me...

  • hmmm
  • Indeed, hence my long winded 'old man yells at clouds' rant.

  • hmmm
  • Its supposed to be a way for Jeep owners to 'atta boy' other Jeep owners for having a nice Jeep. Youre supposed to buy a bunch and keep them with you, if you see another Jeep you like youre supposed to leave a duck on their hood to let them know they did a good job buying a Jeep. Then the owner of said Jeep comes back and finds the duck from a stranger, feels good about themselves and puts the duck on their dashbaord as a trophy. The more ducks on your dash, the more alpha you are in the Jeep community.

  • hmmm
  • The whole concept of dweebs buying an over priced SUV designed for off road use, then not using it off road and making it part of their persona. Then taking it a step further and buying plastic trash to leave said trash on other dweeb mobiles to high five other people whom identify with a stupid truck. Its bananas how easily manipulated people are. Every time you leave a duck on a Jeep a Chrysler executive gets another bonus...

  • Must fight temptation to buy an overpriced raspberry pi
  • No gpio but old centrino laptops make excellent low power servers. My primary server was a first gen centrino from 2011 up until recently and I think it only used 12w idle after putting a SSD in there. Had it's own UPS built in.

  • It's a trip!

  • I was being dramatic, sorry, yes, this!

  • *Permanently Deleted*
  • You would be the bad guy if you make him return it. Personally I would have a talk with your son about how unusual the act is and how his act could be used as leverage over him, nothing is free. Teach him healthy skepticism. Also call back those parents and tell them to fuck off, completly unacceptable they bought something connected and important for your son without checking with you first. They dont know your house or rules...

  • Pi camera in high humidity? Case?
  • There are lots of vendors that just make simple, cheap project enclosures. Bud Industries is my favorite. I have one of these bolted to the back of my trailer with a USB camera in it that I use as a back up camera. Just use some RTV to seal the hole the wire comes in through. https://www.budind.com/product/nema-ip-rated-boxes/ptk-series-fiberglass-box/ptk-18240-2-2-2-2-2/#group=series-products&external_dimensions_group=0&internal_dimensions=0&cover_style_group=0

  • I will make one observation, having worked at a startup I can say folks can easily get swept away in the companies mission if the kool aide is strong enough and leader has charisma. But its frail and had to be nutured constantly, if the aura is broken you're fucked. I think Musk finally shattered his aura.

  • Those of you that back your vehicle into parking spots, why do you do it?
  • Americans avoid it like the plague for some reason. I always back in because I can look at the spot for objects or problems before I start backing in to ensure I dont hit anything. Backing out blind can be risky otherwise.

    So I'm cleaning out a house and found a brand new Gateway2k Pentium 4 computer. Someone opened the boxes but never took the computer out, its all still in the plastic and I don't want to ruin the unboxing for someone that is into this. The computer is free to a good home in the Boston metro area to make your retro gaming dreams come true! Shoot me a message, first come, first served.

    150 Seedlings - into the cold frame

    Started the peppers in March and tomatoes in April. They were getting too big for my grow light so I evicted them outside. Plenty warm in the cold frame in Massachusetts. !

    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" ```

    Where was this knowledge when the Pi supply was low?

    Raspberry Pis Found in Abandoned Spin Scooters in Seattle

    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!

    Does anyone else have a Turbo Button™ on their router? My wifi router is in essentially attic space with no AC so it gets hot and acts up with connectivity issues. My turbo mode solves the problem.

    Driving is more expensive than you think
    news.harvard.edu Massachusetts' car economy costs $64 billion, study finds

    Harvard study says Massachusetts car economy costs $64 billion, and more than half of that comes from public.

    Massachusetts' car economy costs $64 billion, study finds

    "The paper, which the students wrote as part of an applied lab course, found that costs are diffused across a number of areas and involve things people don’t often consider. Beyond those for individual drivers, road maintenance, snow removal, and policing, there are less-obvious ones, such as those associated with added pollution, value of land set aside for parking lots, lost productivity from sitting in traffic, and various costs associated with injuries and deaths on the road.

    Using publicly available data, the authors put the annual public tab at $35.7 billion, which amounts to about $14,000 for every household in the state. Those that do own vehicles pony up an additional $12,000 on average in direct costs."

    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.
