Ordering prototype (3d printing, CNC machining, lasercutting) parts, reimagined. It's a major pain just to get a few parts made- first you find a company that does that, e-mail them their design, they get back to you with a quote and you either accept it or go back to step 1. What if you could just upload your design, select a material from catalogue and receive an instant quote. If you're happy with it, order the pa…

There are services like that. Check out https://www.ponoko.com

Earlier quoted context omitted.

This has potential , especially if you do it with the Matrix .

Good idea. The Matrix is definitely on the list of available experiences. EDIT: If you take the red pill, you get to live Neo's life when he was still Thomas Anderson, go to his job and do all the stuff he would do. It'd be hilariously boring.

I think you mean the blue pill? If I remember correctly, the blue pill was the return to normal while the red pill was the "trace program"

Idea: Tree of knowledge Ever been interested in a topic that once you google you end up with explanations(quite often on wikipedia) that rely on foundational knowledge you didn't even know you should have? And then you started working your way back by googling things you didn't know until you hit something you do know and from that point you try to inch your way forward to the original topic just to get discouraged a…

You reminded me of something that does exactly this for machine learning. I posted it on the front page of HN (Metacademy).

I really want a nice wysiwyg markdown editor. Not the two column layout. I want syntax highlighting, but it should not only do colors but also semantics. Headings should be actually bigger and italics slanted. I tried and failed to make this idea a reality. I got to partial solution using regular expressions. But it is far from functional and reliable but it is only like 200 lines! You can check it out here: https://…

Ok I'll go first. It's an "Imgur for audio files". Now there's times when you record an audio and want to share it. What do you do? Uhh,, umm.... Yup. exactly. There's no reliable, easy-to-use app to share audio files (not music). So, this is a web/mobile app for easily uploading and sharing audio files, and playing them. I don't have a full plan laid out, but I'll work on it for sure. (If you'd like to be notified w…

The reason why this doesn't exist, and can't exist at the scale of imgur is because of piracy.

again not music but audio files. sure there isn't a sure shot way of stopping people from sharing music, but there are some things that can be done. for example, max time limit can be set to 60 sec for each audio file.

Basically Yelp for transgender surgeons. I've been working on making the decision as to who I'll get to sculpt new genitals for me, and researching this on the web is a mess - every site comparing them is out of date, triggers my mental sketchy spam site detectors, or both. It'd be great to be able to go to a nice-looking site and say "all I'm interested in right now is MtF genital surgery", then see doctors who do t…

I feel like this is a symptom of a far larger problem, the need for yelp for medical care in general. Its kind of shitty that there is absolutely no way to quality and price compare medical providers. Also, good luck with the transition, I have a friend going through something similar, its definitely not an easy thing.

Disclaimer: I work at Yelp.

Yelp started out as finding a referral for doctors, and recently Yelp has added public data to their respective hospital pages:

A major pain point in my life is house maintenance and repair. I really miss having a (good) landlord. That's what I want - a single point of contact to manage the upkeep of and fix any issues related to my home. There's so much friction in the process of finding the various contractors needed to keep a home in good order. First you have to search on craigslist, angieslist, or google for contractors that service your…

In Brazil this is offered by insurance companies (it's called home insurance) for a long time. Besides covering stuff like fires, earthquakes, hurricanes, theft, etc. they give you free home services like the ones you mentioned (hanging pictures, changing lightbulbs) and offer "emergency" services like locksmith, electrician and glazier. It's way cheaper than your 500-1k range. Here's one of the companies that do thi…

Though the door man (of one's apt. complex) often does things like this for a small fee, too.

Problem: Completion rates for online courses are dismal and engagement with other students and faculty is low.

Idea: Weekly online, live discussion sections to accompany self-paced video lectures. Discussion sections have 5-10 students and are facilitated by Teaching Assistants

How it works:

Students taking a MOOC course sign up each week for a discussion section. There can be multiple discussion sections to accommodate changes in the student's schedule, different time zones, etc. Students pay ~$10/discussion, once a week, for an hour.

Discussion sections can be G+ Hangout style and taught by crowdsourced Teaching Assistants. These TAs can be grad students in universities looking to make extra money. They can assist students with HW problems, go over tough concepts, and talk about material outside of the immediate subject matter.

TAs can rev share per discussion. Example: 30% rev share for a class of eight students paying $10 each --> $24 for the TA for an hour of teaching. This is significantly higher than market rate (~$10-16/hr)

A tablet (iPad or Android) game which is designed to be used while exercising.

Use ANT or Bluetooth 4.0LE to tie into a treadmill, bike, or other exercise equipment to get output measurements (speed); ideally, find some devices which allow two way commands (not common at all right now).

Networked games against other people, or vs. computer or past personal performance. The interesting part is a "use while running" interface for the touchscreen, requiring inputs (using gross motor skills, not fine control) to do things in-game while retaining performance. Or maybe use audio output for instructions (i.e. "press the blue button, then the red, then the green" while keeping heart BPM above 130, and targets moving on screen.
