My wife and I lived on a Sailboat for a few years. The boat had a 20 year old SeaTalk bus connected to the sensors (depth, wind speed/direction, water speed). I bought a newer radio with an AIS receiver. Of course I wanted to hook it all to my computer & phone. So I built some hardware to interface with the SeaTalk network, the AIS radio (and a modern GPS) https://github.com/johnboiles/Helm-hardware https://github.co…

Nice this is awesome! Well done. Once you have everything in NMEA it really does become very easy to integrate with other marine hardware/software. Literally everything runs on it :)

I build a "SaaS" wine app, for tracking wines in my cellar and for tasting notes as well. "SaaS" in quotes since it runs in a small production setup with all the bells and whistles (ie. CI/CD pipelines, continuous releases, user signup etc.), but I'm the only user :-) I'm a wine enthusiast, i.e. not a professional but interested enough to do a WSET2 in my spare time (I'll do a WSET3 when I find time some day). I like…

Heh, I built something similar for my partner and myself: https://wine.unobtanium.de/ It's not very sophisticated (as we're not sophisticated wine people), but we've sometimes found ourselves standing in front of the wine rack in the super market (as I said, not sophisticated) wondering which of those we already had tasted and how we liked it.

There's not that much in it because it was put on a bit of a break owing to a broken server a while ago, but it's back up again :)

I used to love discovering new music through Spotify's Song Radio feature. But somewhere along the way, they started personalizing it so much that every radio is now basically an echo chamber of the same songs I already know, most of which I have even already added to my Liked Songs. I built myself a small service to "disable" (work around) Spotify's hyperpersonalization by giving me the Song Radio as an anonymous us…

Built a solution to a problem I have always had. I like my system to be clean, minimal and structured. It gets quite tricky to manage multiple projects on my on machine, projects tend to gather and are placed everywhere. Overtime managing system wide dependencies becomes a problem. It is quite easy to mess up a system setting or to keep track of a package I wont need tomorrow. This is why I built freshenv. It is a command line application which helps developers in running and managing completely isolated developer environments locally. It fetches and lets you run environment flavours in the form of docker containers which are preconfigured with tools and packages developer needs everyday.

I use it everyday and some others as well. Which makes me happy :)

I have a rail line right under my apartment, so I built a small computer vision app running on a Rasperry Pi which records each train passing, and tries to stitch an image of it. It has a frontend at https://trains.jo-m.ch/ . Edit: it's currently raining and the rain drops are disturbing the images a bit.

Sharing this with SBB

I hope they notice (also makes me want to guess the location). I am in Zurich and I hope I don't find this spot

One of my big "side projects" over the last few months has been my personal website and blog ( https://epiccoleman.com ). It's not very interesting per se - I mean, who doesn't have a blog these days - but it has been really educational and fun to work on. It's a really simplistic stack which makes working on it pretty frictionless. I spent a lot of time tweaking the look and feel of the site and am pretty happy with…

Well that sure looks similar:

https://pine.fm/music/ChordGear

I rotated the inner ring to capture the sense that (for example) Amin shares two notes with Cmaj and 2 notes with Fmaj, so belongs between them.

You can drag the chord gear, click it for a kind of awful synth-piano sound that I had a lot of fun making, switch modes, etc. I actually originally made this in wood/acrylic:https://docs.google.com/document/d/1lwIS-1sPNyIpYM1nCcFkU9Iq... but I like how the online version renames the notes sensibly.)

Mostly I was just trying to explore music theory concepts, and have a few other toys at https://pine.fm/music

(also the code is gross; I've been a manager for almost a decade now and am rusty; you've been warned, lol)

I created a todo thermal printer so that I can write messages whenever I remember something. For example when I'm lying in bed and I remember that I have to do something or reading a book and think that's a great thought that I should look more into someday. Basically I have a mobile app that I can send a message to a api. Sometimes it's just a note, sometimes it is a todo item. Then I have a raspberry pi that polls…

Thermal paper is nasty stuff. Just sharing it forward.

I watched Stargate-SG1, the series that was on from 1999 to 2010. I bought the disks and ripped them to my Mac. I scraped episode information from various locations (Netflix, Wikipedia, IMDB, etc) for directors, writers, full cast and synopses for each episode.

I wrote a perl script for the terminal that permitted searching all of these items for requested episode patterns/Titles/numbers/cast. The search results include info from every episode where a case insensitive match is found. I also enabled running the episode's video in QuickLook or QuickTime. The search results were color coded to differentiate search/cast/synopsys info. (no color shown below.)

Simplest example searching for a director:

sg1.pl 'William Waring' -terse ( just episode numbers ) Search for "William Waring" was found in 13 episodes: 109, 131, 147, 156, 164, 177, 178, 185, 194, 196, 198, 202, 212.

sg1.pl 109 SG1 Episode=[#109] S5 E21, => 'SG 2001 Stargate SG1 S5 D5_5.m4v', "Meridian", 05/10/02, Director: William Waring, Writer(s): Robert C. Cooper, cast: [Amanda Tapping (Major Samantha Carter), Christopher Judge (Teal'c), Michael Shanks (Dr. Daniel Jackson), Richard Dean Anderson (Colonel Jack O'Neill), Don S. Davis (Major General George Hammond), Gary Jones (Sgt. Walter Harriman), Teryl Rothery (Dr. Janet Fraiser), Corin Nemec (Jonas Quinn), Carmen Argenziano, Jacob Carter / Selmak), Mel Harris (Oma Desala), David Hurtubise (Tomis)], Daniel incurs lethal radiation exposure when he prevents a potentially cataclysmic accident in a weapons laboratory on the planet Langara (P9Y-4C3) but the mysterious Oma Desala shows him that death can simply be another beginning. While the alien government responsible for the lab accuses him of attempting to sabotage their research the Kelownan Jonas Quinn tries to negotiate with SG-1.
