Recently I installed CodeServer (https://github.com/cdr/code-server) on one of my old laptops.

Now I can do my coding using VSCode, except I can do it from any computer that has a browser (although Chrome seems to work the best).

I highly recommend checking out CodeServer (no affiliation)

Earlier quoted context omitted.

My 2012 MacBook Pro is in great condition and probably would’ve stayed that way for awhile, but sluggishness was just becoming too common. Especially when I’m off mains, running an IDE, a browser, and occasionally compiling

I’m still runnin a 2012 (non retina) without any issues, and I plan on keeping it until it literally won’t boot. What’s funny is I was initially annoyed as I got it a few weeks before they announced they were releasing the first Retina display models (discontinuing the non retinas), however getting the last non-retina generation was a blessing because that’s was that was when they also began making upgrading MacBooks…

I am also holding on to mine, and it is my primary machine even though we have newer MacBooks in the house.

Not a company, but sharing a personal project: I got a free broken 55" TV and turned it into a big daylight panel. I got a great explanation of why this works well (fresnel lens) from the DIY Perks channel on YouTube: Turning Smashed TVs into Realistic Artificial Daylight ( https://www.youtube.com/watch?v=8JrqH2oOTK4 ). The main board had failed so the screen was black and the backlight cycled on and off. After disco…

Be careful white (which are actually blue) LEDs may be damaging to your retinas.

CONCLUSION

The study results indicate that LED blue-light exposure poses a great risk of retinal injury in awake, task-oriented rod-dominant animals. The wavelength-dependent effect should be considered carefully when switching to LED lighting applications.

Not very creative: I use my older phone to read books in the hot tub. This way, if I drop it, I don't loose my fancy new expensive phone.

you have a fancy new phone that isn't waterproof? mine is and it's not even that expensive.

Is it soap proof too?

I find it amazing what you can do with old gear. Phones I've used for bluetooth update stations, where a bit of code can read sensors and send emails with the readings (on WiFi). Or small 'stick up' displays where you use the web page widget in Android and just re-read the same web page over and over again.

I used a number of laptops as servers because of the built in battery backup. Less useful when they don't have on board ethernet since USB ethernet can be flakey. Opening them up to disconnect the display backlight insures they don't try to run themselves down by turning on the screen.

I've given away a number of machines to young people who wanted to learn programming and computers but their parents both wouldn't trust them with the "family" computer and they likely could not afford (or know how) to get a free one. Back before WeirdStuff closed in the Bay Area I had an after school activity that would be to take a few students to there and build a machine out of parts, limit $20. Put together some really interesting machines that we would install Linux on and be off and running.

Also have salvaged parts to make things, like PC power supplies to make a benchtop power supply.

I use an old iPad with brightness turned way down as an indoor IP security camera via the free Periscope HD app:

I also use an old iPhone mounted inside the front door as a Touch ID enabled alarm control panel for a DIY HomeKit alarm system. This is using a Homebridge plugin I wrote:

I run https://motion-project.github.io/index.html on a DELL D400 (I think, it's Core 2 ULV), uploads picture to Gdrive. I set it up when leaving for long vacations. I used to run a 24/7 server (bittorrent, HTTP) on a fanless PC originally built for cash desks. Got it very cheap, ran several years till the Debian repo actually disappeared!! Consumption was 19W with HDD. It was replaced with a RaspPi and a SSD. BTW alm…

What do you mean the Debian repo disappeared?

Maybe it was just moved somewhere else, but still it appears they just do not leave the very old versions available on the official ftp's and mirrors. As of now it looks like the oldest available repo is the one for Jessie.

An old monitor + previous generation Raspberry Pi: hangs on the kitchen wall to display Find My Friends in kiosk mode. Connected to a timer so it's on in the afternoon until dinner so you can see the family come home. Really cute to see your children move as little picture icons across the map towards you from school.

Cool idea! What api did you use to query the data?

The Find my Friends web page that apple provides through iCloud actually works really well in kiosk mode (automatically updating, zooming into the relevant part of the map). So I just used one of the many tutorials on how to set up a kiosk om the Raspberry Pi [1]. I augmented it with a little ruby script to check if the WiFi connection was up before loading the page. Also, iCloud logs itself out about once a month, so I put a VNC client on there to be able log back in (but you can also hook up mouse and keyboard).

Reminds me of the Weasley clock in Harry Potter[1]. Really cool, you can probably make a mechanical clock using zones and a simple location api. [1] https://harrypotter.fandom.com/wiki/Weasley_Clock

That is indeed where I got the idea from :-)
