I recently shipped WOPR, a subtractive polyphonic synthesizer with an embedded Game of Life grid. The GoL modulates the various parameters in time with an internal (or now, external) clock. It's for iPad 2 and up. I started it a year ago to learn a bit more about iOS and DSP. It had 9 months of sporadic evening & weekend development over a very busy year, with a 3 month hiatus over the summer.
It's had pretty decent reception so far. Beer money only, but enough that I could have a few every day if I wanted to! It's done better than I ever thought it would; I think because no musician can ever resist another synth.
Subsequent versions will increase in price as more features are added. Right now I'm working on a huge v1.2 upgrade with a ton of stuff people have requested.
(Just posted on HN) my new (ad)venture http://songsasaservice.com the idea is every week people submit suggestions for a song subject (and a bid) and within one week the winning bidder will receive an original song written on the subject. The idea is based on a little 10 week challenge I set myself earlier in the year. This time I thought I'd try and generate some revenue of it :) and use it as an opportunity to create the most minimal MVP ever, whilst simultaneously learning a minimum about python/ appengine and using existing web services to minimise my workload (e.g. Gumroad, soundcloud, appengine, bootstrap). Hope you like it?
2. Where to pee in Antwerp (http://antwerp-wheretopee.apphb.com/). The city of Antwerp (Belgium) has opened up some of its data. This mobile web app get all the toilets in Antwerp and sorts them by distance. Shows that the browser is already capable of running these sort of apps; beats building 3 native apps.
General idea is that each player controls a bunch of soldiers that they can equip and give battle tactics to (flank, use abilities, etc). Battles get auto-resolved with a nice graphical replay (you can check out an early version of that by clicking the bottom right button on the page), so anybody can attack anybody else on the map regardless of whether they're 'online' or not.
Currently coding up a stock exchange based economy for the game so that there are caravans moving between cities for players to raid and generally make the world seem a bit 'alive'.
Obviously a pretty big project to be doing with one guy and part time, but it's surprisingly coming along pretty nicely!
I'm working on Scribe, web-based sheet music notation software for songwriters and composers. Right now the public-facing URL is just a landing page, but if you ping me (contact info in profile) I'd be happy to give you access to the prototype.
I've been some time developing a solution for most of us. It's a website called Parkuik that will use a wiki-like environment to make us easier to find parkings (some of you may have had this problem on your city :-P) with the help of all of us.
I can just develop it when I have some time on weekends, but it is starting to have some users and I hope sooner than later It'll be one of the reference websites for this :)
I'm working a nights/weekend startup that positively conflicts with the subject matter: a better kiteboarding forecast service/app. http://kitecaster.com The idea is to model how kiteable a spot is based on the location, your schedule/equipment, and of course the weather. Prototype is going slow, kiteboarding gets in the way! And I am enjoying doing the full stack using the tech I want (node, Parse, etc) when I should outsource some things, but we're looking good for 2013!
It's only a landing page at the moment, working on finishing the MVP within this month.
What I'm trying to build is a SEO tool that analyze your inbound traffic and gives you a list of keywords to target. It'll analyze the keywords and related keywords and check how competitive they are for you, automatically.
Give me lots of feedback please. If anything confuses you, please let me know.
A kind of Google Now for Movies. Instead of searching for movies, new releases automatically land in your inbox once available as stream and you just need to sort them into "Want-watch", "Saw-and-liked", "Saw-and-disliked" or "Dismiss" folders (for later auto-sorting).
A beta version is available at http://exkino.de for all you native German speaker and learner.
An iPhone app for skiing/snowboarding. Track the stats for your runs on the mountain. Add friends and see where they are on the mountain you're on. Send meet up notifications. Download detailed maps of various mountains. Free to download, with options for upgrading to PRO version and obtaining additional maps. E-mail me at jordan [AT] kingofthemountainapp [DOT] com if you're interested in testing!
I've been doing http://priceflurry.com for quite some time now (I posted about my progress on HN couple of times). It's a service where people can collaborate on prices and deals. It's finally getting some traction (not that big of, but who said it's going to be easy) and I'm really happy to see that :-)
Besides really pretty Russian girl, there is very little benefit to that video. Maybe add some subtitles or spend more seconds on video portions that have text? I couldn't figure out why some things she scrolls have price tags of $250 and some $30 - what is she seeking in such wide price range?
I'm plugging away on a service to allow mobile developers to add messaging and location services (and some simple online storage) to their apps without having to write the backend themselves - and provides high availablility.
Sadly I feel like its become moot, with some rather big players doing that as well. But I might be able to white label it in some fashion.
Been involved in CityBikes for a while, both an Android app to find stations on public bike schemes, and an API that homogenizes and provides the same information for projects, applications and statistical research.
We launched today - http://www.ultimategiftlists.com - we've spent the last week on it. I got bored of having to write an email with a series of links to my family to tell them what I wanted for Christmas and for my birthday so built this..
I, with some friends, created DOM: a bookmarklet that turns websites into 3D platformers using jQuery, Three.js and an accompanying multiplayer server with Node and Socket.io With it we won HackNY and presented it at NYTM
In pursuit of a casual passive income generator, I've been working on a meme creator. It uses HTML5 canvas rather than Flash. I'm only a weekend or so into it, but would appreciate any constructive feedback.
Thanks! Us too – it's something that we feel just hasn't been executed in the right way yet.
We're focussing first on creating a platform for local producers & consumers to connect before we tackle distribution. We've got some interesting ideas on the cards though when the time comes. Would be great to hear your thoughts on it.
I like your approach: test the market without taking risks, and learn on how locals handle it themselves.
Can't think on a better way of doing it. Distribution can kill your idea. At the same time, it's the best selling point of it. If users are buying through the website, they expect a quality deliver, which is not always easy to get, and is expensive too.
On a sidenote: let sellers express themselves. I would not buy groceries from a craigslist-sort site. I would if I can see photos, location, and know more about the product and the business ethics of the seller.
