Greetings!

If any of the info on this website was useful for your projects or made your head spin with creative ideas, and you would like to share a token of your appreciation- a donation would be massively appreciated!

Your donation will go to my Robotics Fund, straight towards more sensors, actuators, books, and journeys. It takes a lot to continue building these robots, and I’m really thankful of everyone who helps encourage me along the way.

Gear Art vs RoboBrrd Banana Transporter

Check out this cool gear artwork piece that we made — or as the RoboBrrds called it, a magical banana transporter!

Watch the video for the entire story:

How this project came about was we wanted to create something for our backers on Patreon. Our first ideas were rather inanimate. We needed something that could move and look interesting. The gear art is the result of this thought.

The .stl files are available for you to download and print one yourself. You can find it on our Open Source Hardware page.

We also captured some ‘making-of’ timelapse footage and compiled it into a video:

One of the aspects of the design that surprised us was that we couldn’t find a formula for aligning the gears via experimentation. All of them required a ‘fudge factor’ in either their positioning or diameter. We got around this by just focussing on making each gear mesh with the one previous, and then finally working on the final gear.

Here are some of our favourite photos of the project:

We are experimenting with story-telling with our robots. We want there to be an entire world of these robots, where they are always plotting, building, and generally goofing around. Hopefully it makes the video more interesting and enjoyable overall.

One of the areas that could improve would be the speech bubbles. If they are added later in the video editing process, we could focus on animating the robots rather than moving the bubbles in and out. We have to learn different video editing software for this, it might take a bit of time.

It’s fun to get lost in Planet Zimpopodu with the robots. Let us know what you think!

If you want to see more projects like this, as well as behind-the-scenes sneak peek previews, consider backing us on Patreon.

Thanks for watching and sharing our new video. We’re already excited for the next ones! :)

Progress Update: Nintendo DS + 3DP Game Controller

3dp_game_controller_pkmn_2

The goal of this hack is to make an interface to the Nintendo DS. We use Caleb Kraft‘s 3D printed game controller pieces (D-Pad, 4 Buttons) for the interface.

Been working on this for a little while now, and finally hit a milestone with it.

Here is a progress update video!

Took a while to figure out how the buttons on the DS worked. Finally figured it out, and use a level shifter to trigger the buttons from the Arduino. The Arduino is also checking the button presses from the external 3D printed controllers, then sends the corresponding press to the DS.

I want to document this very well so that other people can do this too. Been taking lots of photos throughout. Caleb Kraft’s talk at the Open Hardware Summit was really eye-opening, and I think it’s cool how the ‘copy & paste’ empowerment can have such a huge effect on people that really need it. Games are fun, and everyone should be able to play them. Why should physical ability prohibit what happens in the gaming worlds? So unfair.

Will also be trying out a speech recognition interface, wonder how well it will work. If you have any other crazy ideas for interfaces, let me know.

RoboBrrd @ Open Hardware Summit!

RoboBrrd Open Hardware Summit 2013

RoboBrrd was at the Open Hardware Summit! The Brrds were running demo programs, and entertaining the passing by humans. The tentacle mechanism was also above, swooshing its tail around!

In addition to the three Brrds, we also displayed all the photos of RoboBrrds that other people have made! It was fantastic to have these displayed, and it was definitely like everyone’s RoboBrrd was there in spirit :)

RoboBrrd Open Hardware Summit 2013


Thanks everyone for posting photos of your RoboBrrds on social networks (and keep it up)!

I met up with Sabine from the Robots Podcast and Robohub! It was VERY COOL to meet her in person, and we recorded an interview about RoboBrrd. It will be showing up on the podcast later this month, in a series about robots and education.

RoboBrrd MIT

She also took me on a tour of her lab, and the research that she is doing. WOW, I learnt some really cool things about nanotech!!! (Thanks Sabine!!!!)

Afterwards, RoboBrrd and I walked around MIT some more.

RoboBrrd MIT



The funny part while walking around was that other people touring around saw RoboBrrd and thought that I was a student there. I wish I was smarter so that I could attend MIT. Also, I wanted to visit the Media Lab so much… maybe next time.

Open Hardware Summit was interesting this year. I went in thinking that it would be a little more futuristic, but still people were seemingly still stuck on the question ‘why make OSHW?’. This is a good question to reflect on from time to time, and especially before the summit, so that you can unveil deeper questions.

This question essentially sums up what I was interested in:

In what ways can kit makers add OSHW to the core experience of actually building the kit — aside from just adding the logo and writing tutorials? How do we start the motivation to make modifications, even if the person didn’t have any initial interest in it?

I wanted to pose this question to the panel in the afternoon, however they decided to cut the line too short. (Yea, I was ANGRY!)

I did of course pose the question to some people around the summit, and the responses were split into:
- ‘Wow, yeah, that’s a good idea- it would be cool to figure out how this can happen’
- ‘That would require more time, that we don’t have! We only do OSHW to release our files’

Of course, it is the second response that annoys me. There are some people out there who only do OSHW for the ‘badge’. Their reasons are that they do not have enough time, people would never look at it, this is all that is required, etc.

One of the speakers, Matthew Boragatti, gave a presentation about essentially how everyone needs to document their work. This is so true, and definitely hits on the above issue. Maybe there can be the invention of a tool to help with documentation or something.

Going back to the original point, hopefully in the near future, more OSHW makers will be interested in figuring out how to communicate that “YOU can modify this”! :D

I really enjoyed seeing all my friends in person again. I gained so much words of wisdom and advice from Massimo, what a great opportunity to chat with someone who has essentially given rise to the maker movement with the Arduino Team. It’s my goal to exercise the advice in real life. ;)

The badge turned out a lot better than I thought it would, it was pretty nifty. Though mine was slightly damaged from it smashing on the floor when diving under the table (more on that later).

Thank you to CircuitCo for the BeagleBone Black- always wanted one of these! Still have no idea what to make with it, but stay tuned for some future projects that’s for sure! Also thanks to Sparkfun Engineering for the RedBot Kit- it will be interesting to add this on to RoboBrrd for some wheel ability. ;)

Something that can be improved for next time:

The demo tables and poster set up was poorly organized. Our demo table was partly hidden by neighbouring posters, so we had to squish everything together. We also had to assert that we definitely needed the entire table, otherwise it would have been split in half with another project. In order to escape from behind your table, you have to go underneath it, and when you come up be careful to not knock over one of the posters. To add on to it, I didn’t even know demos were allowed to enter earlier than doors-open time, so I was standing around for nothing. It’s nothing serious, just little frustrating things that sort of crack into your excitement for the day, especially when you were waiting an entire year for this one day! The demo chair did the best with what he was given, which was not enough extension cords, and posters all over the place.

After the event, there was a dinner for all the women involved with OSHW. Some of the discussions were interesting, involving circuits and pcb programs, but then some of them were about guys and other things. I don’t usually hang out with other girls, so maybe this is or isn’t common. I wouldn’t know, I haven’t been surrounded by > 5 women in two or so years (aside from this dinner of course).

There’s now a Google Group for all of the women involved in OSHW, so it will be interesting to see how that will develop. I’m looking forward to discussions about how OSHW inspires girls to start making things. :)

A lot of the other women enjoyed the dinner very much- so thank you to OSHWA, Adafruit, and Sparkfun for sponsoring the dinner. Also, the nachos were super.

A big THANK YOU to the Ada Initiative and Open Hardware Summit for the travel grant, otherwise we would not have been able to go and learn about these new thoughts.

The most memorable moment was just walking along the night before- and a RoboBrrd Backer comes up to me and says “I love my RoboBrrd!”! It was AWESOME!!!!!! :’D
