As a Bose engineer, thank you! Most folks don't realize all Bose products are designed in Massachusetts.

Or master and slave boards...

Yes and because wiregurad is stateless you'll need a script that checks if your DNS endpoint has updated and restart the wireguard interface so it pulls the fresh DNS/updated IP address. I had to make said bash script for my nodes.

Way too thin to add useful insulation. Much more likely for sound deadening to stop horrible echos.

I ran it for awhile but the upgrades even in docker because unnecessarily difficult and annoying. They often rolled out so many incremental and useless updates instead of one large one every once in awhile. I abandoned it for mattermost.

I live in Massachusetts and take the most lazy route for composting because I have space. I just rake up all the leaves in the fall into a giant pile near my compost and all year long I just layer leaves and greens. Once a year I start a new pile and occasionally I'll turn the piles. Otherwise i let worms and critters do their jobs! I'm setup as a host on ShareWaste and have other families bring their compostable junk to me so my piles are substantial.

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.

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.

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.

Most folks ignore laptops, but if you're OK with USB storage or getting the special caddy to install the internal 2.5" drive you can get great deals on laptops. This one idles around 4W with the screen off.

Status symbol and to project a personality.

I'll upvote the heck out of any gnome stuff. Still like their first album best but I enjoy any good new metal and this is great.

 

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.

P4 Computer - Gateway 2000 model 510 - part number 2800434

17" TFT Monitor - Gateway FPD1730

Speakers - Boston Acoustics BA745

Edit: Found a taker, hopefully it goes to it's forever home on Saturday!

Edit edit: its gone!

 

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.

 

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?

 

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

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

Startup Configuration for GPIO

#!/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."

#set direction
echo "out" > /sys/class/gpio/gpio17/direction #cuckoo movement

Flashing Light Code

#!/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))

        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!

 

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.

 

"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."

 

Found some tiny coffee plants while in Hawaii and thought they looked amusingly fake so I grabbed a picture.

 

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.
