Ask HN: What's your quarantine side project?

I've also made quite a bit of bread - very satisfying first thing in the morning.

I used the change in routine to put spare time into launching a specialty coffee indexing site[1]. I've been thinking about it for +1 year.

Still working on the backend and the ultimate goal is to tell you when harvests from producers you've liked before are back on sale (i.e. I liked this coffee last year, what might I like this year), and build a kind of engine to recommend coffees.

(It's also a testbed for ruby continuous deployment with Docker!)

I wrote a system so that people can help me to identify the steam traction engines featured in each one of my photograph collection.

The premise of the system was simple, you view a pic, type in the registration / license plate then move to the next. It has only three options, add, none visible or same as previous.

The system is offline at min whilst I prepare more images but here is a screen grab:

I advertised the link on a forum which I post on and was amazed at the response. The first 10k images I'd prepared were indexed within 24hrs and then a second batch of 20k in the same timeframe. The quality of results was very good, less than 5% error rate.

Ultimately I am going to choose the best and add them to a web site.

Some guys have said they'd like a similar system for their own photos. I suspect there could be a solution there for things like railway / transport photograph community.

As an Android developer, it was hard for me to find a place to copy & paste deeplinks on a device that didn't have Slack. So, I created a lightweight Android app that allows you store any time of link and open it: https://play.google.com/store/apps/details?id=com.appdex

The TDA, biggest art student competition in Europe, was scheduled in Barcelona in April. Because of COVID-19 it was impossible for the few thousands students to meet there. So I made a mobile app to host the competition online, which replicated all the rules of the traditional contest. It got around 2000 signups during the week of the contest and made the competition possible remotely. I decided to keep it live and run new contests for artists everywhere in the world during lockdown. You can check it out and vote for your favorite artists, or join the contest yourself, there : https://greatest.app.link.
