As a braille user, I was always fond of "laptops" without a built-in display, simply to save ssace, weight and power.

I found a braille display which features a small compartment with micro-USB inside. Used a Pi Zero (these days 0w) to transform that braille display into a full-features Linux laptop. I documented the first version here: https://blind.guru/brlpi.html

A device that waits for the SSID of my Olympus WiFi-enabled camera to show up and then sync all new photos:

I use a Raspberry Pi to stream PlayStation 2 backups over SMB by networking the onboard Ethernet port of the Pi to allow access to a Samba Share service running on the Pi. This allows for seamless playback of games with heavy Full Motion Video sequences as the Ethernet transmission is faster than the max throughput of the USB2.0 ports provided on the PlayStation 2. It -also supports auto mounting and sharing of exter…

This is amazing. I have to do this.

There's a bus station across from my studio / coworking space. I can see people waiting for the bus and doing either: 1) staring into the void 2) looking at their watches 3) desperately glancing in the direction where the bus is coming from. I figured that it'd be nice to let people know when the bus is supposed to be there. So, I installed a 28" display on a monitor stand, installed the stand on my window frame, tur…

really cool project man, props! bit strange they don't do this ,but i suppose Canada is A LOT larger than my country so perhaps it's harder to roll out decent services in all places :D very nice stuff though! the most annoying thing in the world to me is waiting on something without a clear indication of when the wait will end so you are doing a big big service to these poor people :D

Could something like this be used for synchronization in such a scenario? https://ncase.me/fireflies/

Thank you for sharing this! I love it. It's beautiful. Unfortunately, I also have literally no idea what you're proposing. I would like to, though.

It is visualisation of simple technique to synchronise many clocks without central authority, algorithm is explained on left side of website. You need to turn on 'Nudge thy neighbour" and then wait for fireflies to sync.

I am going to use one to try to replace my Echo Dot with. I only use Spotify, TP-Link lightbulbs and power plugs, timers, reminders, and weather, so I think replicating this functionality with RPi and Mozilla IoT Gateway should be a fun little project.

I rigged up something where by I can see and operate the garage door at home. It even works by talking to Siri to get it to do its thing...

I monitor several solar plants with old syntronic inverters using node installed on rpi. Works 24/7 without any problems.

I have a few Raspberry Pi boards and since I've seen folks doing stuff similar to what mostly do I thought I comment on something I hadn't seen yet.

I struggle with tinnitus distress and Ménière's. One of my coping strategies is to continuously play some sort of background sound in the areas I occupy.

I have a first gen RPi with a set of USB powered speakers in my bedroom that plays long form background soundscapes I get from YouTube on loop. This is the lowest tech I could muster. YouTube-DL is a command line tool that fetches content from places like YouTube and recodes it. I use mpg123 to play the resulting audio file on loop... and because I'm already using ssh for all sorts of other things as go about my day this workflow is basically completely integrated into my normal day-to-day activities.

When I first started doing this I changed the audio track on a fairly regular basis. Sometime to suit my mood, other times for the weather. These days it's more of a seasonal thing.

It works great. It's proven to be really reliable and it was really, really cheap.
