This is the correct answer. Or use old school pink insulation.

One newer alternative my contractor used is timber hp, its physically like a block of firm tofu so you take the chunk/board and muscle it into the joists and it just stays. Its cool but cutting it looked miserable.

They tried to poach me. It probably would have been an amazing job, i knew a bunch of the people that would be on my team. Noped out.

In the early 2000s there was a dive bar in Boston and people started scribbling grout puns in the grout between all the subway tiles at the urinals. It was all so brilliant, drunk poets, but I hardly remember them at this point;

Oscar the grout

Who let the dogs grout?

Twist and grout

Grout minds think alike

Etc

Optimism doesnt pay my bills :) excellent they make compact, 12v refrigerant based coolers now. Learned something new!

Sorry to be Debbie downer but if thats a 12v car fridge it almost certainly uses a Peltier cooler which is extremely inefficient. Theyre only designed for day trips, its going to use a lot of electricity for that task.

My budget is under 100w for 3 servers with a combined 18tb of ssd and 28tb of spinning rust that stays spun down unless I need to so a cold backup.

Mmmm rabbit stew. IMO the best rabbit stew, Stifado. I used to help my grandfather in Greece dispatch and butcher the rabbit, then they'd go right in the pot.

I havent grown Sarracenia for over 15 years but it looks to me like a lack of air movement and lights. Plants need natural air movement to encourage them to grow strengthening fiber to help keep them upright. Also they need a lot of sun and might be stretching sideways looking for sun. Those are my best guesses.

Most folks think I'm crazy for cutting and splitting wood. Makes me feel great and I get heat out of the deal. Crossfit is for silly people and 40s ain't that bad.

If thats truely melted plastic then more likely is you had a partial short and the 19V was dumping bursts of high current between the rings and slowly heated it. The question is what got between the two rings that made the partial short. Was there any organic or conductive stuff between the rings that you removed?

When the mug is on the base do you get a power indicator to tell you its working?

I dont think its a fire hazard but its certainly suspect. Gouge out the burnt plastic and see if there is a PCB hiding under the surface that those two gold rings are part of.

Riding on top of this top comment, I'm and electrical engineer, looked up you mug and its only 19VDC which means its almost impossible to have arcing with such a low voltage and that big of a gap. Try cleaning it, looks like a critter to me too.

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

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.
