Making Podcasts? Hacking Podcasts!

Maker / Hacker Podcasts

So what is the Gentleman Hacker or Lady Maker listening to nowadays in the way of podcasts? I don’t know… but I can tell you what I’ve been hearing. Here’s a round-up of some of my most recent podcast delights.

Hackerspace Digest
Recorded by the crew at Makers Local 256 in Huntsville, Alabama, the Hackerspace Digest is one of my favorites (and not just because they’ve mentioned Milwaukee Makerspace and myself a few times.) They typically talk about things happening at other hackerspaces as well as things they’ve been working on. Most of their focus seems to be US-based spaces, which is fine… we’ll get all international later. They provide ogg files for people who love freedom, and mp3 files for people who love convenience. Check it out.. Hackerspace Digest is probably one of my favorite podcasts right now.

Hack All The Spaces
I was excited to hear about a podcast from the UK! Out of Nottinghack came the “Hack All The Spaces” podcast. The members of the London Hackspace tend to talk about UK hackspaces (yeah, they are called “hackspaces” over there instead of “hackerspaces”) and ramble on about various hacking/making related topics. The audio quality still needs to improve, especially since they are no longer in the same physical location when they record. All podcasters: If you’re not using The Levelator, you should be! I often have problems listening in the car due to the difference in audio levels. (Granted, my car is pretty noisy.)

The Hackables
As long as we’re across the pond… a fairly new podcast called “The Hackables” put out two episodes (000 and 001) so far and the second (001) was better than the first (000) so that’s good! They are a motley bunch, sort of like the Hackerspace Digest crew, but with British accents and a lot more laughing. (I love British accents, and if you’re doing a UK podcast and you don’t have a British accent, you should get one!)

The Amp Hour
Alright, let’s head over to Australia and… Cleveland? The Amp Hour is two engineers talking about electronics (and other things) in a no-bull manner. I’ll admit that Dave took a little bit to get used to, but he’s pretty hilarious, and both he and Chris are smart guys. The Amp Hour gets a little too “electrical engineery” for me on occasion, but it’s definitely informative and entertaining.

Robots Podcast
Welcome… to The World of Robotics! If you’re into robotics, this is the podcast for you. It covers uh, the world of robotics… from researchers to commercial robotics companies, and the latest news and events. It’s about robots, duh. (It’s also a bit more professionally produced than a few of the others I’ve mentioned.)

Make: Talk
Our friends at Make have been talking to the makers who make the articles that show up in Make. Make: Talk is a fun series where Mark Frauenfelder interviews people about the cool stuff they do. So far they’ve all been pretty interesting to me but I think my favorite is still the one with Steve Hoefer. If you like Make you’ll probably like Make: Talk.

The Engineering Commons
Chris Gammell from The Amp Hour wasn’t satisfied doing just one podcast so he teamed up with Jeff Shelton to launch a new engineering podcast. As of right now they’ve only done two episodes, so it’s early days, but it could be one to keep an eye on.

Engineer Vs. Designer
New to me (but they’ve done nearly 40 episodes) is a podcast with an engineer and a designer which they are surprisingly calling Engineer Vs. Designer. I’ve listened to two episodes, and I’ve got plenty more I want to dig into. EvD is a pretty polished podcast, which fits them well.

So that’s my current list of “podcasts that I am listening to” right now. If I’ve missed any you think I should be listening to, or have any good recommendations, or just want to tell me what you are listening to… please do!

Holiday Make-A-Thon 2011

Make-A-Thon

Join us Friday, November 25th, 2011 at Bucketworks in Milwaukee, Wisconsin for the 2011 Holiday Make-A-Thon!

The event is family friendly, fun, and free. (Though donations towards materials will be accepted.)

The guys from Milwaukee Makerspace will be there… so should you!

Some of the activities include:

  • Learning to soldering
  • Gourd painting
  • Knitting
  • Hand-painting ornaments
  • Gift-wrapping station

See who else is coming (and RSVP) over on Facebook.

Those interested in helping out by volunteering, or who just want way more details, can check out this Atrium thread.

Logging the temperature and humidity

Adafruit DHT22 temperature-humidity sensor

Last November one of the Arduino-based projects I started working on was a temperature logger for the office. With winter coming up I wanted to see just how cold it got. (The office is in a converted attic, and the heating and cooling leaves much to be desired.)

I picked up a TMP36 – Analog Temperature sensor and got it wired up and wrote some hacky perl code to read the data and log it. I never really got it out of the experimentation stage, and ended up pulling the Arduino out for another project. (Isn’t that often the case!?)

So last month when Adafruit came out with the DHT22 temperature-humidity sensor I figured I should grab one, and maybe I’d get around to finishing the project.

My temperature (and humidity!) logger is still not done, but I did whip up something to run this week while Wisconsin is having a heat wave. The office has a window air conditioning unit, but it only runs when someone is in the office. When no one is there, it gets hot. How hot? Well, now we know….

23:30 37% 84°F

Chart

The hard part of the code is provided by Adafruit’s DHT-sensor-library and their DHTxx Sensor Tutorial was also useful. And just for fun we dug up another old bit of perl which was wired up to SuperTweet.Net so we could send the data out via the 2XL Networks Twitter account.

2XL Networks - Logging

I should really get around to finishing this project, since I have a spare Seeeduino that would be a good fit for it. I can always feed the data into Pachube or roll my own logging application.

I’m really just hoping the heat wave ends and it doesn’t get up to 98°F in the office again…

Diavolino

Diavolino

Remember when I wrote about Cheap Arduinos? Well, if you do, maybe you remember the Diavolino.

The Diavolino is a damn cheap Arduino clone, coming in at about $13. (I say “about” because if you want some headers, or a battery pack, or a chip socket, it’ll run you another few bucks… but still, you can get away with just $13 for the base kit.)

Even though I said there was an “extremely detailed assembly guide” there were a few places where I got slightly confused, mainly just in the “power options” section. (I wasn’t even drinking when I put this kit together, unlike the last kit I built.) Since I got the Diavolino with the 3 x AA battery holder for $1, it was simple to just go with that option. Obviously you’ll need a FTDI USB-TTL cable to connect it to your computer to program it. Again, leaving out the on-board USB makes this kit nice and cheap. (I did get a socket for the chip, as I don’t like to solder chips directly into place.) My only real complaint is that, even though the board looks cool in red and black, it can be a little hard to read the type on the board to locate the correct pins. Then again, I tend to prototype in dimly lit rooms.

I got this kit put together in about 40 minutes. (In fact, I even made a time lapse video showing the assembly.) This seems like a pretty simple kit for a beginner. In fact, I could see the Diavolino being used as a kit put together in a class for people wanting to learn soldering and basic Arduino programming. (As long as you can send them home without an FTDI cable.)

The Diavolino appears to have been designed knowing that in being low cost, a few sacrifices had to be made, and I’m OK with that. If you know how you want to use it, it shouldn’t be an issue at all. (This one is destined for a robot.)

Holiday Make-a-thon (Time Lapse)

As we often do here at RasterWeb!/2XL Networks, we made a time lapse video… this one is from the Holiday Make-a-thon that was held at Bucketworks recently…

Some of thing things that were made: LED ornaments, handmade wrapping paper, recycled bags, popsicle stick ornaments, and lots and lots of art… Oh there was also knitting, and at least one maker worked on a YBox. There’s probably a lot I missed, but then I was busy making things as well. It was great to see kids and adults working side by side creating things, hopefully we can do it again.

Thanks to Bucketworks for hosting the event, as well as sponsors Milwaukee Makerspace, and UberDorkCafe.

Oh, and if you missed it, don’t worry, I hear they may be planning another one soon
