I'm designing a 3D printed robot arm that doesn't suck.

It uses all brushless outrunner motors for at least the 4 large axes (final two in wrist may be hobby servos for now).

The arm is similar dimensions to a human arm. Initial calculations show it will be able to lift more than 2kg at full extension if I can make it strong enough. Actually the (rough) calculations say more than 10kg but that would break something. It's also 200 milliseconds for 90 degrees of shoulder movement, supposedly.

All hardware and software is open source, including the brushless drivers.

It uses low cost 3D printers. I am currently using a $320 Monoprice Maker Select modded with a 1.2mm nozzle and I will be adding a $450 TEVO Black Widow modded with a 2.5mm dia nozzle to the mix. I may try a pellet feeder. The goal with the large nozzles is to increase strength and reduce print time so it's not maddening to print. This will make it easier to iterate.

My goal is to make an open source low cost arm that is useful for manufacturing, and then design open source workcells for it and actually use it for productive work.

You can look at the jumble of CAD BS right now. https://cad.onshape.com/documents/5b474270e4af0ef979e6fade/w...

Find the tab with the assembly called "Arm3 Assembly".

Please fork it and contribute.

I'm working an a visual-language that compiles to RegEx that let's you write scalable and readable long regexes.

https://github.com/karyfoundation/orchestra

It gives you 2 compilers and one IDE that let's you edit Orchestra code and then compile it to RegEx or compile RegEx to Orchestra...

Project:

http://lightscript.org

A concise dialect of JavaScript built on Babel (superset of ES7+JSX+Flow). Has been a lot of fun to build, and a lot more fun to program with.

Problem: The moderately cluttered syntax of JavaScript (Python and Ruby have cleaner syntaxes, while JS is the platform we're bound to use for many things).

Problem: My experience taking audio tours at various museums showed the use of antiquated and expensive hardware. Most alternate solutions used mobile apps which are inconvenient to download and take more time to release. Project: I went about developing a web app that allows anyone to quickly create an audio tour for free: https://www.youraudiotour.com/create I also integrated Amazon Polly to automatically generate…

I like this idea but extending it to the whole world based on geolocation. Use an app and earphones to find voice/text descriptions of places and landmarks, monuments, sculptures, buildings, etc. Everything can be geo-toured.

Of course in a museum is perfect but based on geolocation it doesn't have to be linear, you can go anywhere in the museum and get voice/text about that particular place/masterpiece and when they are changed then easily change the audio/text for the place.

Love it!

http://www.eathow.com/ EatHow is a web app that helps you plan your meals and gives you recipes you can make with the food you already have. Long term Id like to completely automate grocery shopping and meal planning so all you have to do is a one-time setup where you set a budget and diet preferences and Eathow takes care of planning everything else. While anyone who cooks at home would find it useful, it would be p…

I like this idea, and I'd enjoy hearing more about it. (Email in profile if you're interested in discussing further.)

Problem: Kickstarter et al founders not communicating shipping information. I'm looking at you Antsy Labs! Project: Crowdsourced backer shipping data. A backer can share their order date, delivery date, and optionally their order number. This allows other backers to see when (if!) orders are being shipped and delivered. We can then estimate when backers should get their order. Audience: Kickstarter and Indiegogo back…

Nice! I saw someone spin up something very adhoc but similar when the Mavic drone was released and delayed.

I can imagine something similar being helpful when the Tesla 3 launches but not sure how to get the shipping data...

Web app for making resumes. As of late I've been bombarded with individuals and companies asking for me resume. But following several years of freelancing and entrepreneurship, I don't have one. Thus, I'm making a web app with Vue, and Mongodb to demonstrate my skills, and help others who find themselves in similar situations make their own resumes.

Continuing to build "Oh By"[1].

I launched it last year and saw some initial traction and use - and was surprised and delighted to see how some folks put this tool to use.

Right now, we are adding a "raw" output mode that will allow you to use twiml code in an Oh By Code ... I like the idea of giving people a free, anonymous, instant (and throwaway) address for twiml ...

Project: Gauntlet.io (https://gauntlet.io)

Problem: it's tough to run multiple security tools and get a quick security assessment of a web application.

Description: It runs multiple security scanners against your application and consolidates the results. It's great to integrate to your delivery pipeline. It's free forever for 1 target :)

I've had a project on my mind for a long time now. Just for my own entertainment value.

I wrote a Python script a while back that would take two people's Google Location data (from Google Takeouts), and find out where they've crossed paths. I found out that my girlfriend and I were only a mile apart, within 5 minutes of each other, two years before we met (she was gracious enough to download her location data and share it with me..). It was a horribly, horribly, horribly written script, that I made when I was just learning Python. But the results were pretty fun.

I've since wanted to rewrite things and extend this idea to an entire 'agent' system, where you can import data from any source that lets you download it (Facebook, LinkedIn, Mint, Google, etc.), so that you can 'recreate yourself'. In other words:

me.photos(date='2016-01-01') would bring up all the photos I took on that date. Or me.location(date='2016-01-01') would bring up all the places I was that day. Or me.texts() would show all the texts I've sent via SMS or Messenger, or Hangouts, or whatever source I've allowed importing of.

But the most exciting idea for me, would be to make this into a life story of sorts. On a map, animate what places I went, who I sent texts too (and what the contents were), what I spent money on, etc. And allow me to do analytics on all of my data - where am I most likely to spend money on snacks (mint + location)? How fast do I tend to walk when I'm at work (fit data + location)? What's my favorite grocery store? Who do I text the most when I'm at the bars (sms/messenger/hangouts + location)? What time of day do I write the most angry emails (sentiment analysis + Google email data)?

Then if you have friends who don't care if you know everything about them, let them import agents and somehow have them interact. Recreate an entire world. Then somehow import this data into Unity or some other game engine, so you can recreate your virtual self. Watch yourself move through life from a third person view. Or first person. Whatever.

Given the sensitive nature of data like this, I figured I'd write code for this and somehow do all the processing locally. But I'm not a software engineer and really haven't been able to move forward with this idea. It'd really be for nothing other than my own amusement.

It's funny how, after a long day at work, I'll sit down and be determined to finally start materializing some of them, but then realize that all the excitement I had about the ideas in my head isn't enough to overcome the RSI in my wrists, or mental fatigue from working all day.

Maybe at some point I'll finally get a move on with it.
