A similar thread was posted a couple of years ago. If you have any side projects that you've built and that you no longer have time for, I'm sure the HN community would have an interest in hearing about them.
<a href="http://westoncb.com/projects/tiledtext" rel="nofollow">http://westoncb.com/projects/tiledtext</a><p>A new form of text editor designed from the ground up for lower precision input devices (e.g. motion sensors, touch screens). Demo video at the url above.<p>I had issues using mouse and keyboard and gave up programming for six years until the concept behind this hit me. The actual software is an engine/framework for producing particular text editors (I figured I'd need to extend it to in a similar manner to Emacs, so that I could efficiently do, e.g., command line things too). <i>It could also be configured to edit natural language documents for text editing on e.g. mobile devices and VR</i>.<p>Editing and navigating documents is done, and there's a system built, but not yet attached to the UI, that is effectively a universal autocomplete: you give it an EBNF grammar for some language and it can list all grammatically valid options (that you could insert) from any point in a document. (I'm thinking of extracting and open sourcing that part. Not sure yet, though.)<p>I worked on it for a year and half, had an increase in medical bills and had to work more—haven't touched it much for a couple years. The copy on the website is oold.
<a href="http://wordsafety.com" rel="nofollow">http://wordsafety.com</a><p>I made this last year, but failed to build on the initial audience... There's no revenue, so any offer will be considered.<p>The site was launched in August 2015 and got 79,000 pageviews in its first month. It also got some media attention which has given the site quite good search engine ranking: it is a top-3 Google result for most of the relevant keywords and search phrases.<p>I can also throw in the domain BabyNameCheck.com. There's no site there currently, but you could easily reuse the word check back-end from WordSafety... Just make a new baby-themed design and it could be a site that any parent would want to check out when trying to decide a name.<p>(Edit: Please don't post word suggestions in comments - there's a form for that on the site :))

I have a project where I "reverse engineered" this world class poker bot: <a href="http://www.slumbot.com" rel="nofollow">http://www.slumbot.com</a>. I have something akin to a "what would slumbot do?" API where you can enter the parameters for a heads up poker situation (hole cards, aggression, etc.) and get back a decision. It's far from perfect (and the code is a mess) but it worked surprisingly well in practice. I don't have time to work on it since I've started a new job and online heads up poker is kind of dead at low stakes but it might be useful to someone? Drop me an email via my profile if you're interested.
Hyperbook (<a href="http://getbook.co" rel="nofollow">http://getbook.co</a>) is for organising study notes and research information.<p>I used many bookmarking/note-taking/wiki software while writing my research thesis. Found limitations such as searching, linking notes and revisiting bookmarks. Currently it is used by many students, book authors and research scholars at top universities in India. . Maintained the site for two years without any revenue model. Want to maintain the free version for more years to come.
<a href="https://www.freesunglasscompany.com" rel="nofollow">https://www.freesunglasscompany.com</a><p>It's an e-commerce fashion store for sunglasses. It is very similar to a website that sells watches, freewatchcompany. The website is built off the Shopify platform, which is amazing. Products are dropshipped from China, and made easier using an app called Oberlo. I don't put any additional time into the website, though I should.<p>I advertised using Facebook/Reddit one time and made over $100 revenue in the first 24 hours (end of September), then got busy and haven't touched the site since. The site is pretty much setup and ready to go. You would have to run through the site's products and confirm that the seller on AliExpress is still in business and still has the product, but you can easily use Oberlo to wipe out all inventory and start over with sunglasses that you want to sell.<p>The sunglasses are all $0 to the customer, but we charge for shipping, which is where the profit comes from. The "free" brings the customer to the door. Typical sale is $10, with profit being between $6.50-$8.00.<p>Any tips to market the site or make it better are appreciated, as well :)
I'm interested in selling <a href="http://www.seasonalysis.com" rel="nofollow">http://www.seasonalysis.com</a>. The site has been around for over 4 years and has a wealth of seasonal market data.

I think with the right marketing campaign and site content it could be quite lucrative but I just don't have the time.
I wrote a very popular iOS animation program, FlipBook, and a friend wrote a companion Django-based website, flipbook.tv. Then I hired a group to write an iPad version, FlipBook HD.

<a href="https://www.browser-details.com" rel="nofollow">https://www.browser-details.com</a><p>Written in Django, got some HN love a while ago - no signups for a while now but we have over 500 accounts that signed up at some point.

But I never got the time to get the product to where I wanted it to be (pay a $49 fee to get a good legally binding agreement based on the data you provided that you can just download, print and sign, and avoid problems and lawyer fees) nor market it properly (I also think it would be great to partner up with people who organize hackatons etc).<p>Built in Rails, hosted in DigitalOcean.<p>Email in profile

It is very sturdy because it runs off of Amazon S3 for all the content serving.
It's not that I don't have time for it, I'm actually looking for a partner. I'm making a DIY Chromecast-clone Software solution, which you install on Debian and you can use our apps to cast stuff to your TV. Great way to repurpose an old PC, or test out a rPI, etc... It's meant to be semi-proprietary, and it's great for countries where Chromecast hasn't launched and 2nd hand ones go for as much as $100 which is a price of a refurbished Intel Atom PC :S. Mail me at (my username) (at) gmail (dot) com if you're interested and want a demo over Skype or something. It could earn money by showing ads on the screensaver or simply being pay to use...
