Just until recently I was usging an old Nokia N85 for my running sessions. It had dedicated physical buttons for playback, skip song, volume etc, the "Nokia Sports tracker app" also suported polar heart rate monitor.

Some years ago it stop supporting direct upload of workouts and I had to send the gpx file via bluetooth.

Last year battery died and I haven't found cheap replacements.

I'm in the process of turning my Toshiba Libretto 110CT (a subnotebook from 1998) into a simple remote terminal (over ssh) with custom server software to handle emails, rss feeds, chats and so on. It runs under FreeDOS and connects to WiFi by a combination of PCMCIA ethernet adapter + mobile router with built-in battery. I love the form factor and the "oldschool" keyboard, I have regenerated the battery and it's quit…

Have you any info about how you regenerated the battery?

I sent it to guys that regenerate laptop batteries, but next time I will do it on my own because you basically replace the cells, weld them together and its done - here [1] you can find detailed guide for Libretto.

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 almost all the laptops at home have been bought used (usually in Germany where offer is plenty). All the tablets (Google Nexus 7 1st gen) have been bought used. No regret when kids break one.

I've built a good ol' web app which runs in fullscreen mode on an old iPad 1, turning it into a "smart" picture frame. Runs on top of Trello, with a small backend in Go for caching and proxying. Works great.

I have an original iPad here just waiting around to die. Something like this seems like a perfect use case for it. Thanks.

Earlier quoted context omitted.

I bought a x230 last year as my non-gaming computer, and I really like it. I bought it for 117€, it was pretty beaten up. The display is the cheap TN panel, has a light spot in the center, and the keyboard doesn't match my locale. However, it has the top-level i5. (i5-3380M, I think). I also bought a docking station at a bargain. This year, I bought a new IPS display, a matching keyboard and a new screen bezel for it…

Enterprise ThinkPads are amazing machines. They're very sturdy (although the X230 notoriously has a weak screw holder in the top left (or is it right?) corner that will almost always break and make that corner of the case a bit wobbly. Annoying but not critical. And the i7 top of the range version that comes with the 180GB Intel SSD... Well, the SSD is bad and can be thrown out. It has a bug in its firmware that was…

IPS upgrade?

Tell me more!

I use an old laptop (single core, 1g ram) as a remote desktop client. Since I work regularly in two different locations this allowed me to buy only one workstation which I keep at one location and that old laptop allows me to use it from the other one. TBH I initialy did it as a fun project/experiment but was amazed how well it worked[0] and stayed with it. [0]That being said both locations have a fibre and the dista…

Is there any specific thing you did apart from having a fiber and being close ? I tried to set up my home PC as a server with tincVPN and X2go, i couldn't get a usable performance. Well, to be fair i tried using KiCAD remotely but even the XFCE desktop interface felt sluggish. I also had fiber on the three nodes (Vultr server, home server and my local machine).

Did you use WiFi? An old Wifi router can easily add half a second of latency. Even high end Wifi endpoint still adds a few ms of latency which can be significant considering that short distances (20 miles) of fiber has sub ms latency. A software router or switch can also add up to a ms of latency. Could also try SSH (tunnel) instead of VPN as SSH encryption might be faster.

I use a bad Xiaomi Mi A2 for watching preloaded vids during commute, and playing OpenMW !

It was my partner's former phone but she eventually broke the camera, and it was quite sluggish. However, it has a big screen, a big battery life, and had cost me 150€ anyway.
