Ask HN: Any unfinished side projects to give away?

170 pointsby 10y ago
130 comments
Would anyone like to give away / sell the projects which they've started but have no time or interest to finish?
10y agoHN ↗

Sounds very interesting to me - can you provide some more information about the current state, features and technology?

10y agoHN ↗

I would like to know more about it. Maybe it could be put to use. Which technology is it in? Can you share why you don't want to pursue it further? You can mail me hemantshinde at gmail dot com

10y agoHN ↗

this looks more like a company than a side project?

The blog says the company has already been acquired by another big company...so how can you sell it?

10y agoHN ↗

He states that his project was "like" badgeville.com, not that it "was" badgeville.com :)

10y agoHN ↗

Can you share your interests / capabilities upfront? Definitely have some side projects gathering dust but they need to go to a good home...

10y agoHN ↗

I built DocsApp[0]: Documentation Hub for Your Developers. It is 90% completed. It is similar to readme.io.

If anyone interested to buy, please contact me. Email is in my profile.

The main reason I plan to sell is because marketing it is too hard (I am developer).

[0]: https://www.docsapp.io/

10y agoHN ↗

I have one side project GTheme.io[1] selling Ghost.org premium themes. Some improvement (SSL, auto payment to sellers, content blogging, etc) can be done to make it as passive income. 11 of the themes are designed by myself.

As my focus shifted, I plan sell it.

[1]: http://www.gtheme.io/

10y agoHN ↗

Which themes are yours and how much would you be willing to sale the copyright to them for?

10y agoHN ↗

It's a shame that Assembly.com had to close - you'd find tonnes of interesting side projects there.

10y agoHN ↗

Yes. A fully automated business for 3D prints of ultrasound scans in glass cubes. The USP is that you upload a low res scan (most doctors don't want to give you access to the full 3d data) whereupon it does image processing to create a 3d point cloud which it puts into a reverse engineered laser engraving format. If payment is processed on the bundled website it then sends the engraving file and delivery sheet to a sub contractor. Profit. Everything ready to run. Wasn't so very happy with the point cloud quality though, but it's probably good enough. Ran out of interest just before the marketing phase. Hackers eh.

10y agoHN ↗

Interesting! I don't see any contact info in your profile, how can you be reached?

10y agoHN ↗

Very interesting, can you email me at tom [at] printtopeer [.] com?

10y agoHN ↗

Sounds like one of those things that is awesome at the time (everything related to a new baby is), but more like something that will freak you out and make you think 'why!!' a few years down the line.

10y agoHN ↗

We hardly looked at the 3d baby scan again after the real thing turned up.

You'd also need to deliver fairly quickly as 3d scans are normally done later in pregnancy so the baby is plumper and doesn't look "like a skinned rabbit" (that was a quote from a midwife) and you'd still need to deliver before the baby pops out.

http://localqueries.com/ Make localized google searches from any country or language in the world. See how your keyword is performing in Cambodia for example. It's working, just need some follow up.

10y agoHN ↗

Wow. I was going to build this exact same thing. And I still might. Would love to chat. My emails in my profile-- didn't see yours.

10y agoHN ↗

Also interested in something like this but I don't think I have time to do it on my own. If you end up taking it up and would like some help, give me a shout.

My email is miguel at <username>.com

10y agoHN ↗

This looks awesome. If you take it on and want some help, especially with an iOS or Mac app, please let me know jasongrandelli @ gmail

10y agoHN ↗

By the way, GNUCash is great for that sort of thing.

10y agoHN ↗

It forecasts your spending easier than mint, and it was developed back when mint was only open to US and Canada, not sure if it still is.

Hi Mitchell, I'd be very interested to discuss this with you. I've been working on a similar application for over a year. What would you expect from the right person?

10y agoHN ↗

If you take this on, I'd also be interested in helping out.

10y agoHN ↗

Just to keep it open, and keep basic usage free.

10y agoHN ↗

Great - I'll send you an e-mail with more info :)

10y agoHN ↗

Hey Mitchell, Merlin from https://thisisbud.com here. Looks like a cool tool you've made, what's made you close the door on it? I've sent an email over to you anyway as I'd love to hear more about it.

10y agoHN ↗

I don't want to close it, just pass it on. I use it myself but neglect the maintenance of it.

I had been building http://wishcan.com, a drag-and-drop travel planner, and will hand it off to someone willing to continue the work. Trip planning is difficult to get right, and notoriously hard to find a business model for. I think it's simply because no one has gotten the UI/UX perfect. I am now working on an IoT platform called http://smartxlab.com

10y agoHN ↗

Cannot agree more with wishcan. I sketched up a few different ideas for something like this, but never pushed on because I thought integrating with hotels, airlines, etc. Would painful. Also figured I'd need to automatically parse email confirmations, which would be a PITA.

What is it written in and how much work is left to do?

10y agoHN ↗

I often wondered if automating the pain point you mention above (integrating with hotels, airlines etc.) and providing a singular, specialized API for that would be an amazing business opportunity. Seems like one of the existing travel companies could do it, or a travel agency.

10y agoHN ↗

Strikes me that you could turn this around somewhat...

When people are publishing what they want, that looks to be a good starting point for travel/lodging companies to come in and make offers to these folks.

"You're looking to stay in Bucharest on Sept 18 and 19? Our hotel can offer you XZY for $ABC on those nights."

Sort of like lendingtree-model for travel. Not quite sure why that's not taken off yet, other than, perhaps, larger company IT systems?

This could possibly work well for smaller regions - contact a local chamber of commerce and have them have all the local businesses make offers to people looking to stay in areas on specific days.

Basically... define a format and let them integrate with you if they want access to the market you've defined, not the other way around.

10y agoHN ↗

hey it looks polished! my wife and i are planning for a trip to Taipei mid-Sep, so i'm wondering if your app is usable (at least until end of this month).

10y agoHN ↗

WishCan is incredible - really well done! Any thoughts of open sourcing it? I would love to host a private version for my parents. Thanks.

10y agoHN ↗

Good job so far, just add some airbnb hook there and you got income.

10y agoHN ↗

Definitely like the user interface here. I normally do this kind of planning in Excel or Sheets, but it's hard to "visualize" the trip in tables. The timeline is great.

10y agoHN ↗

Looks very interesting, what options would you consider as far as partnering to have someone continue the development?

10y agoHN ↗

I just used Sygic Travel (https://travel.sygic.com) to plan a very last-minute road trip in Iceland. I knew nothing about Iceland to begin with. I spent less than 8 hours planning the whole trip, and ~ 5 of them were in Sygic. It was great! Post-trip, I can attest that using it helped me make the most of my time in Iceland. I was well-informed during the trip (at least on par with most other travellers I met), and ended-up seeing most of the popular spots.

I think Sygic did a great job with identifying the key user stories:

1. Ability to see a list of interesting places to generate ideas (they've partnered with Fodors, the content is comprehensive, at least for Iceland)

2. Ability to set my travel dates and schedule places that I want to visit on specific days

3. Ability to see places on a map so that I can schedule more efficiently. (I was able to schedule places in different regions on different dates, and thereby minimise driving times)

4. Ability to view and order daily itineraries (list + map) and ability to estimate travel time for a given itinerary. (This helped me avoid being over ambitious and gave me plenty of room to breathe during the trip)

5. Ability to see/book hotels on a map that have availability on my dates. I ended up making all my hotel reservations (4 nights) through their Booking.com integration. Never have I been happier to click on an affiliate link! The ability to visually plan your days and nights within the same interface really helps. Without this, I would have done what most last-minute travellers in Iceland do – book a hotel in Reykjavik (capital) for the entire stay and take day trips in/out. This would have severely limited my coverage of Iceland and cost more.

6. Ability to take my itinerary with me. They have a easy to use (free) mobile app with premium features e.g. offline maps. Paid for the premium features but didn't end up using them as internet worked great in Iceland!

Overall, the interface was really well done, albeit with a 3-4 hour learning curve. I found myself needlessly bouncing back and forth between ideation and scheduling.

I jotted down a few ideas while I was using it:

- Break down planning into several stages: Ideation, Scheduling, Reservations. This would allow the interface to be more streamlined and reduce cognitive complexity of planning

- Provide the ability to algorithmically cluster places into days and find shortest path for overall trip

Anyway, wish can looks great! I'd love to contribute. I'm a pretty good programmer (iOS/Web), professionally a senior product manager, and also have decent design skills. Let me know if I can help. I haven't coded for the web in a while so would prefer to team up with someone with up-to-date front-end skills.

10y agoHN ↗

Where can I contact you? I run a website in the vacation space that ranks well on Google for over 100 keywords. I was planning to expand my website and build a drag n drop feature like the one you did. Let me know if I can reach out to you via email, or you can send me one at thepredestrian@gmail.com

10y agoHN ↗

And just to add on to my previous comment (can't edit it), I have over a 1,000 email subscribers from my website. Haven't actually done anything with those emails yet, but I think marketing to them can be accelerated if I get my site to be more user-friendly and feature rich. Would definitely be interested to talk to you about it

10y agoHN ↗

WishCan looks pretty awesome. Great job! I built something very similar: http://www.travelizer.io/ - Although it's not as further along as WishCan. Interesting to see so many people attempting to solve the travel planning riddle but it's tough to get it right.

10y agoHN ↗

I have built a platform for Networking - specifically for conferences, meetups & business gatherings.

We hosted one conference i.e Apple's WWDC.

[1] http://wwdcconnect.com

10y agoHN ↗

I've had similar idea running around in my mind - would love to get a headstart. Shoot me an email at the reverse of moc.eborpdnes@nadeeffoc

Having built and given up on an app that did exactly this, I would like to learn more about your experience. I am in the process of giving away the app, back-end, etc. as a result of a flippa auction. https://flippa.com/6895313-curia

10y agoHN ↗

An idea came to my mind when I was selected for Apple WWDC. There wasn't a platform to find who else are attending WWDC event.

Connect is an Online platform to meet other attendees before the event -

We build this platform keeping following in mind -

- To share accommodation

- Airport Cab sharing

- A trip/ Sightseeing new city

- Or Business Networking

10y agoHN ↗

That's awesome, you are doing much more than I did in the past. Kudos. If you want to connect and bounce ideas you can find my contact in my profile.

I've been making a podcast discovery app, it's not live yet but the latest home page screenshot is http://imgur.com/a/Bkn7Y (basically: Trending topics, Recommendations (based on social media profile and listening history, subscribed shows, and iTunes charts), and instant search of over 4.5 million episodes across more than 60 thousand shows.)

I may not be able to keep going on it though because of constraints on time and resources. Would be happy to talk to anyone who'd like to partner on this (or ideas about how I can at least handle hosting bills for such a large DB!). firasd at gmail.

10y agoHN ↗

Interesting! Cool idea.. I'm curious to where you got all the podcast data?

10y agoHN ↗

Got the Show info from iTunes charts feeds, then parsed the Show feeds for Episode info :)

I made a program for one handed keyboard input. it has a rather unique way of selecting symbols, and it can insert it into any X11 window. So far it's in far from polished. It runs on Ubuntu if you download some rather common libraries. Take a look in the Makefile for details.

I won't have very much time to continue the development.

https://github.com/richard-jansson/veta

10y agoHN ↗

This really looks cool. But you should add some brief instructions on how to compile the code in the README!

I only managed to compile the code after one hour of work. Then I'm kinda new to ubuntu.

apt-file search

helped me out a lot. It was only when I could use apt-file to search for pc file that I managed to install the necessary deb packages.

10y agoHN ↗

This is something that I've been designing and playing around for a while...

I wanted to implement a generic MUC protocol bridge. Kinda like https://sameroom.io/ is doing, but open source.

My initial approach was to look at Matterbridge (a mattermost<->irc bridge) and go from there. But I simply don't have time to do it anymore. The author is interested by the approach though so ... have at it:

https://github.com/42wim/matterbridge/issues/9

--

I'm also the author of https://github.com/jleclanche/django-push-notifications and I don't use it anymore, but it's a very popular django app. If someone around here is using it and wants to maintain it (or part of it), please reach out - I tried handing it off to Jazzband but that doesn't seem to be happening.

10y agoHN ↗

I built http://mlist.io but currently don't have time to do anything beyond maintenance. If you interested in email newsletters let me know!

10y agoHN ↗

I haven't downloaded the app but, by far, this is the best concept on this thread!

10y agoHN ↗

I just started using this last week! It's just what I needed and is amazing - thanks so much for this!

I think I'd be willing to help with this.

10y agoHN ↗

Very cool concept. I would love to use it and help it.

10y agoHN ↗

Should have said you can send me an email - noah.tovares at gmail dot com

10y agoHN ↗

I have been holding on to http://ampoll.com for a while. Technologically, it's there despite a couple of bugs but I've not touched it for over a year now and will probably scrap it in the near future.

10y agoHN ↗

Interesting concept. For tech/coding specific lists, we have the various awesome lists on GitHub, but this is a generic approach and solves a more general problem.

I like to save and collect resources. For me, I feel that Chrome bookmarks with folder hierarchy is enough for me to save links, but this will be useful for discovering new stuff.

10y agoHN ↗

The second problem you mentioned is main reason why I'm building my another project - GGather.com (you probably saw popup about it on Enboard).

10y agoHN ↗

Why does it pop up something about another site? What is ggather and why do I want to "Be first to gain access to GGather alpha release"?

10y agoHN ↗

It's another project that I'm working on right now. The popup is there because the GGather.com will be somewhat similar to Enboard.

10y agoHN ↗

I'd love to partner with you on this! Will get in touch through your contact form.

I made WordSafety.com [1] last year. It got some positive attention initially: #1 on HN, and about 79,000 pageviews in the first month... But then I just basically forgot about it, because I was so busy with other stuff. Now, after a year of complete neglect, the site gets about 1300 sessions / month.

If someone wants to take this over, I'd be happy to entertain any offer. The app itself is exceedingly simple (a database-less Node.js app), so hosting costs practically nothing.

I made a music recommendation site: http://recommendindieband.com

After an initial successful post on the indieheads subreddit, it's slowed down to about 15 users per day.

I also had people writing album reviews and they kinda got bored by it so it's been a while since the last review.

If this is a project people would be interested in (built in python / flask), I'll throw it up on github.

10y agoHN ↗

yeah sure, the dns address is not registered anymore (getsdone.io), but i built a productivity app in sinatra; basically it leverages tweet like syntax and allows people to quickly delegate tasks to other people or oneself and track progress on those tasks. e.g. @paulgraham set up meeting for project review at 1pm tomorrow, pick up milk @danny. i basically got the web app up and running, but due to having to work on my full time job and other priorities, i just stopped after the dns name ran out after a year, i might be wrong, but the aws machine is probably still being charged, so all you'd need is a new ssl cert and renew or rebrand the dns name. never really got around to using it myself because most users wanted a mobile client.

I have built https://www.writedown.co an opinionated immutable Twitter like social network that has most of the features you would expect (something like Akasha). I wanted to make it compatible with blockchains also. Nodejs (ES7) + Ractive + Orientdb. Didn't get much traction / I lack PR skills. If you think you believe in the idea/cause you can either take it or work together (it is almost feature complete).

Blanqd. It's a prett neat daily news headline quiz app concept. Built hybrid style and works on both iOS and Android. The quizzes are generated daily using NLP word substitution hacks.

We (me a and a friend) built https://board.creonomy.com a visual bookmarking/inspiration organization tool for visual creative professionals, some of them are teams within big corporations that want to pay for the product because they got burned by free stuff such as Pinterest. It is on autopilot. Triple digits paying customers. It also raised an angel investment (that for reasons we can elaborate about if interested, we turned down). A new, better version with much more features and more polished UI is 95% done on my dev machine. Definitely looking forward to someone with the time and drive to make it bigger.

http://octave.im/

Web IDE for GNU Octave (open source Matlab alternative). Originally built it because Octave had no UI and installation was a pain. It was heavily used by Machine Learning Coursera students and currently just pays for its hosting.

I'm sure it could be useful in niche academia market, but don't have time/connections to pivot. NodeJS/React/PostgreSQL/websockets. Email address on the home page.

I've built a couple of App Store & GPlay apps that I am not actively developing or marketing anymore due to lack of time. I believe they have good potential and the ideas can be reused to create similar experiences but you need to invest more time and resources. Prefer to sell but I am open to discuss any interesting options.

- Really Funny Fish Aquarium is a game where kids click on moving fish, who make funny noises and movements [1][2]

A web app to have additional metrics in google analytics (your fb fans, youtube views etc,twitter followers etc). Basically it spiders your fb/twitter/youtube pages to get info and send it to ga via measurement protocol. It stayed online for 2 years, put offline a few months ago.
