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!

DIY Cell Phone

Laser-cut plywood and veneer case

How much do I love this DIY cell phone? Quite a bit! I’m not trading in my iPhone for this (yet) but I love the idea of being able to order parts from SparkFun and Adafruit and dropping in a SIM card and having a mobile phone for under $200.

I can also imagine that such hardware could be incorporated into various projects where voice or text communication could come in handy. I know that some folks attach phones to balloons or incorporate them into other remote monitoring systems… so what if you could extend this simple DIY phone hardware to be exactly what you want to fit your project?

I also love many of the other projects I’ve seen from the High-Low Tech group at MIT. (If only I could have met some of the people involved with the group while I was at MIT last month!)

Maker Business – Lessons Learned

Maker Business - Lessons Learned

This one goes to 11! While there are Ten Rules for Maker Businesses, and I covered them all, what I didn’t do was a full-on follow-up post. So here it is.

Just as a reference, my first post was on February 20th, 2012, and today is April 26th, 2012. So that’s just about two months.

And here are the 10 rules, which I’ll address individually below. (Each one links to the original post on the subject.)

1. Make a profit.
I’m happy to say I did this. It took about a month and a half to sell 10 units, and after all was said and done, I believe I hit the 2.3x rule. There were some miscellaneous costs in there, but even with those, I did alright. This is important because if you don’t make a profit, it’s difficult to consider continuing. As far as how much my time was worth, I think I did OK. Not great, but OK. I’m convinced that with increased efficiencies things will improve.

2. It takes lots of cash to stay in stock.
I kept my stock low, which kept costs down, and helped ensure I didn’t have overstock just sitting there. Sales were slow at first, and when that happens you get a bit worried. You start to think about sales, or discounts, or something. I stuck with it and didn’t do any of those things, which turned out fine. Actually, I got lucky in that I had 4 orders in a two day period, right after I wondered if I’d ever sell another unit.

3. Buy smart.
I bought just the right amount of components to build 10 units with no real leftover. This worked out well, except in the case where I got really picky about quality. Buying larger quantities can help lower the shipping costs, but that doesn’t always work, and sometimes buying in bulk is just too costly.

4. Basic business rules still apply.
No problem here… I felt confident on this one, and there were only very minor things I had to deal with business-wise.

5. You get no leeway for being a maker.
I’ve not needed any leeway yet (fingers crossed) as all of the customers have been awesome, and I’ve done my best to be awesome to them. You know, there’s only been 10 customers so far, but it’s been close to 100% pleasant. The only issue I had was with people who are interested in the product, exchange a number of emails with me, and then I never hear from them or receive an order. It’s not extremely disappointing or anything, but just a little bothersome.

6. Be as open as you can.
I’ve been pretty open, maybe not as open as I could have been, but since this whole adventure was based on a pretty open blog post, I think we’re good with this one. I did re-write the code a little bit mainly to make debugging a little easier, and I should probably push that code out, but honestly that’s probably not a huge deal as there’s code out there that works fine right now. I’ve also been sure not to bet the farm on this one product, which is why I’m keeping the production run small. If the opportunity disappears, it won’t affect the business much.

7. Create a community to support and enhance your products.
With a small user base and a simple product, there hasn’t been much need for a community. If one magically appeared I’d support it, but I probably don’t need to run out and force one into existence.

8. Design for manufacturability.
As mentioned in my post, I didn’t design for manufacturability, but now that I’ve done some “manufacturing” I’ve come up with ways to make things easier. This is really just applying better manufacturing techniques next time. I managed to get a properly sized hole saw, which means no more filing, which will speed things up. Win-win!

9. Marketing is your job.
Doing the marketing was fairly easy and I didn’t need to get too aggressive. I’ve got a lot of experience with branding, marketing, writing, photography, and building web sites… and that’s what I did. I first built the store, and then shortly after that I got my Etsy store. The Etsy store was definitely a good idea, as it accounted for almost half of the sales.

10. Your second most important relationship is with your package carrier.
While I learned a lot about shipping, not all of it was fun, but hey, I’ve got shipping down pretty well now. I’m sure there are ways I could improve things, but so far I’ve not been annoyed enough to investigate them. I was disappointed to discover Etsy doesn’t allow you to require a phone number for orders, since FedEx seems to require a phone number for shipping. (Yes, I could enter my own number, but I’d prefer to have the customer notified if there are delivery issues.)

Branching out.
I did make a modification to the product… I decided to offer The (Bare) Button for sale, based on a number of people asking for it. I ended up getting an email from a guy who wanted the bare button, we agreed on a price, I got one ready to ship, added the order page… and never heard from him again. Luckily I didn’t really invest much (besides a little bit of time) into this diversion, because I’ve yet to make a sale of The (Bare) Button. Still, it’s an easy thing to offer in the store, as it’s just the button without the case, so I can easily keep it in there for the DIY folks.

In conclusion, the experiment went well, I learned quite a bit, and I made a profit! I’ll keep this going in small manageable quantities and see how far it goes. I’m trying to be realistic in this endeavor and I know that it’ll probably not be any sort of huge money-maker, but if it keeps going as it has been, I’ll be pleased.

Oh, and if you know anyone who needs a button… :)

DIY Mouthpiece Puller

Last year my youngest daughter took up the trumpet, and shortly after she started she managed to get the mouthpiece stuck. This is pretty common, from what people in the know tell me. The problem is, the school used to have a mouthpiece removing tool, but it either broke, or it no longer has it, which means I had to take it in to the music store, get a loaner, wait for the repair, and then go pick it up and return the loaner… Hassle!

Pictured below is what a mouthpiece puller looks like. There’s also a more tooly/clampy version, which is the only kind I had seen at the time.

Mouthpiece Puller

The commercial version is $40 USD, and while taking her trumpet in for repairs is a pain, it’s free since we are on a rental agreement (for now anyway.)

After she got the mouthpiece stuck a second time (!?!?) I wondered if I could make my own tool, and it turns out I could.

DIY Mouthpiece Remover

It actually looks very similar to the commercial version above, even though I didn’t see that one until I started writing this post. I was using screws between wood for another project that needed an adjustable platform, and I borrowed the concept for this.

I originally put calipers on the mouthpiece to get the right size, and then drilled holes into the two pieces of scrap bamboo I had. At that point the project sat dormant, waiting for the mouthpiece to get stuck again… which it did a few days ago.

I ended up making some very inelegant rough cuts into the bamboo with my jigsaw, and got it so the thing would slide into place semi-tightly, and then started turning the wing-nuts to apply pressure and force the mouthpiece off. It was tricky! I didn’t want to apply too much (I am not a professional band instrument fixer!) but when I thought it was all the way, I tried twisting it slightly. I don’t think twisting it works at all, and in fact I think it’s the wrong thing to do, because of the possibility of damaging the instrument. (Again, I am not a professional!) So with just a little more turning of the wing-nuts, it popped off!

DIY Trumpet  Mouthpiece Puller

I was quite pleased, as this meant I didn’t have to make two trips to the music store, and my daughter would have a trumpet she could put back into the case again.

Two more things… If I designed a trumpet case, I’d add some sort of special door to the side so you can put the damn thing in the case when the mouthpiece is stuck. I know this might encourage people to not take out the mouthpiece, but it’s no fun carrying around a trumpet with a stuck mouthpiece and the case it won’t fit into.

The other thing… Every school that has a band program should have one of these. Heck, if there are at least 3 other kids playing trumpet, I’d see if they could all pony up $10 each to supply the school with one. Even if a band director couldn’t remove it every time, it would be a good first line of defense.
