Ask HN: What personal tools have you built?

I have three tools I have built

1. A amazon lambda that converts files to mobi and then sends them to my kindle address. sendepubtokindle.com works but only for <= 10mb, which doesnt work for me

2. an iphone app that allows me to keep track of my wine cellar, and creates + emails a pdf to me with a menu for when people come over, so they can look at the list and we can pick wines

3. an iphone app built on top of google maps that allows my girlfriend and I to track restaurants we want to go to. you can do this with google maps kinda, and we have been doing it with instagram save post feature. but my app so far is doing a better job.

I'm building a dashboard that behaves somewhat like a news program, with weather and scrolling headlines, as well as reminders for upcoming todo list and calendar entries, and streamer for the stocks that I and my partner own. I also plan to have something akin to spaced repetition of things I want to commit to memory included. The dashboard is still a work in progress since until now I'd been doing these things as separate items, but when it reaches a point that I'm comfortable with it, it'll be uploaded to github.

It currently uses more screen scraping than I would like, which is why I'm not uploading it yet. It probably would break some policies if I shared it in its current state.

http://github.com/marceloboeira/awsudo -> This tool helps me to authenticate withing different roles on AWS.

Currently building (not finished yet, hence no GitHub link, but it's coming) a personal wiki along the lines of TiddlyWiki, but written in Python rather than JS.
