Miltalkee

Wow, somehow it’s been months since I first mentioned my entry in the Great Robot Showdown, and it’s been another (or a few more) since I promised a write-up on said robot… so here it is.

Proposal

For the Flying Car Milwaukee 2013 event there were a number of competitions held, one of which was the “Great Robot Showdown” which tasks people to “create an energetic, entertaining robot that actually does what it’s designed to do.” And noted that the robots would be “unleashed at the Flying Car Gala to delight and entertain the crowd.”

How could I resist? I had already shown things like the Friday Night Drawbot and the Arc-O-Matic at previous events in Milwaukee, so I figured I needed something new, something specifically for this event.

Miltalkee

I wrote up a proposal describing what I planned to build, included a quick sketch, and some links to previous projects, and mailed it in. About a week later Dana and I were putting a bid on a house, and I got a call. I checked my voicemail later and found out I was selected, which was awesome, but it also meant I had about 30 days to build the robot, move everything I own, and also take part in a gallery night I had committed to. Fun!

It was time to get to work! My plan was to cut all the pieces of the robot from 3mm Baltic Birch plywood. That stuff is great to work with if you’ve got a laser cutter handy, and we happen to have one at Milwaukee Makerspace! There was a lot of cutting to do. Basically the robot consists of 8 “boxes” of various sizes to comprise the body, head, legs, feet, and arms. After cutting and assembling everything (with glue and strategically placed magnets) the pieces were painted with grey primer, and then with metallic silver paint. All sprayed in my home-built spray booth.

I ended up spending the majority of my time doing the physical build, all the time thinking the programming would be the easy part. I was (mostly) right. Since I was using a Raspberry Pi I was in my comfort zone. A bit of sudo apt-get for the right packages, some Perl, a text file, and we had a talking robot. I ended up abandoning the idea of a screen or LCD display of any kind due to time constraints, but it’s an idea for the future.

There is a hole in the center of Miltalkee’s chest where a speaker goes. It’s a powered speaker, using 3 AAA batteries, which works well in a semi-quiet room, but in a large room filled with people and music, it’s not exactly loud. (I should thank Dori Zori for turning down the music a bit!) If I ever want Miltalkee to be extra loud, I can always run the output to an external amp I guess.

One of the neat things about Miltalkee is the construction. The faceplate and chestplate are interchangeable, and if I get ambitious in the future, I can swap them out for new ones. This should make upgrading to a screen fairly easily.

There’s a bunch of technical stuff I’ve not included in this post, mainly because I’ve already rambled too much. In future posts I’ll talk about the Raspberry Pi, the code, and a few other construction secrets.

Enjoy!

Remember back in July when the South Shore Frolics Parade make its return? Milwaukee Makerspace was there! And now… there’s proof!

Since I like attaching a GoPro camera to things, I stuck one on my car, which was in the parade, and shot a bunch of footage. So now you can relive the entire parade in just 60 seconds. Also, I left out the audio because I thought you would enjoy the silence.

You can also see this video on Vimeo if you’re so inclined.

Flying Car MKE

Remember Milwaukee Innovation Week? Sure you do, or maybe you don’t, it doesn’t matter because it’s been replaced/re-branded as Flying Car Milwaukee!

June is a super-hectic month around the RasterWeb! World Headquarters, and even more so in 2013, but that didn’t stop me from submitting a proposal to their Great Robot Showdown contest, and yeah, I got accepted, and I’ve got less than a month to finish building the robot I’ve proposed. There’s nothing like a deadline to get things done!

So besides getting a presentation ready for WordCamp Milwaukee that weekend, I’ll be attending the Flying Car Gala on Friday, June 7th at the Potawatomi Expo Center to show off my creation and hope it doesn’t burst into flames before the prizes are handed out.

If you’re not into robots but enjoy fashion, design, or film, there’ll be plenty of those things as well. (But seriously, if you’re not into robots, why are you even reading this!?)

There’s a ton of other stuff going on during the week, just check the events page. If you’re interested in making the world a better place, join out friends at Bucketworks for the BuildHealth Workshop. And if you happen to get in on the Innovation Factory Tours you may see me building the aforementioned robot at Milwaukee Makerspace.

(June’s my month… you may not be able to avoid me! Mwuhahaha!)

Radio Milwaukee Radio

I started working on this project months and months ago, so I should probably share what I’ve got so far… as always, it’s a work in progress.

If you live in Milwaukee and listen to the radio, you’re probably familiar with 88.9 Radio Milwaukee. I’m certainly familiar with it, as it’s a great station, and not just for the music, but for their pieces that spotlight the great things happening in Milwaukee.

Since I don’t actually live in Milwaukee right now, it’s a little difficult to pick up the broadcast at home, but no worries, since they stream it over the Internet, we can use a Raspberry Pi (a cheap single-board computer) to play the stream.

Radio Milwaukee Radio

All we need to do is add some power and some speakers (and a little bit of code) and the Radio Milwaukee Radio is ready to go!

I used this post to figure out how to run a script at system startup. Since the Raspberry Pi runs Linux, I’m comfortable mucking around on the command line via SSH, others might not be, but since the worst thing you can do is destroy the entire system and have to re-load it onto an SD card, the risks are small.

Oh, and here’s the script.

#!/bin/bash

mpc clear
mpc add http://radiomilwaukee.streamguys.net:80/
mpc play

MPD is the Music Player Daemon, which deals with playing the stream, and MPC is the Music Player Client which controls the MPD server. The script tells mpc to clear whatever it’s doing (just in case) and then add the 88.9 stream, and start playing it.

(It’s a bit more complex that just that, as there are some startup services that need to be added, but I still need to clean up that code.)

I’ve seen a lot of complex Raspberry Pi radio streaming projects, and while I’ve also played around with different clients to control things remotely via a browser running on a phone or tablet, I wanted to keep this really simple, and create a single-purpose device that did one thing… play the awesome stuff I hear on Radio Milwaukee.

(I also put together a short video showing it in action.)

Note: I also wrote up a post about laser etching the logo on the Milwaukee Makerspace site.
