What Happens When: Deranged DIYs and Humbled How-Tos

Whiskey Hotel Whiskey

You have just downed a bottle of whiskey. You go to hotel, and then you have some more whiskey. These steps, while extremely repeatable, will have drastically different outcomes for each person. One of these outcomes is a Do-It-Yourself disaster. Another is “How to get a hangover… or worse,” depending on what else is brought into the mix.

So, what happens when you follow this recipe?

The culture of the internet world is changing. Creation is shifting to curation. With so much information right at your fingertips, almost anyone can learn how to do almost anything. A quick g00gle search will already tell you how to get 6-pack abs, and build a flame thrower. i.e. You don’t need to re-write that and create more GI. However, what we don’t know, and possibly want to know, is what happens/happened when you got your abs and made a dangerous weapon. This is unique information that only you can produce. Thus, we should continue to create.

DIY ain’t dead. You should absolutely do things yourself for the learning experience. This also does not mean that you should not write How-Tos; there are tonnes of things that we don’t know how to do, or have learned how to do incorrectly.

But, don’t stop there (or do if it has been over done). Teach us about your experience. Tell us What Happens When (WHW).

What? So What? Now What?

Robots are better than I am at my job, or they soon will be. In education, many kids have lost motivation and can’t concentrate. The internet is a better teacher than I am. Children know what they are supposed to learn, and in general they understand why they are supposed to learn it (they just saw it all online yesterday). However, a frequently missed component in education is what we can or should actually do with that knowledge. i.e. What happens when I apply this information?

I was recently taught this process of inquiry:

What: What are you taking about?
So What: Why are you talking about it?
Now What: What do you do about it?

The last piece is really what still makes community and classrooms relevant, but sometimes we forget to teach that. Maybe it’s because of our consumption-only habits. Maybe it’s because someone wants to keep us under control. Maybe it’s because we keep stopping at “maybe,” and only choose to watch from behind the glass.

Technology is here.
It will can help us.
Now what do we do with it?

“What part of recreating dinosaurs and putting them in a theme park was a good idea?”

Many story premises are ridiculous, but it is undeniable that they are also entertaining. If we wrote a story exclusively about “how to extract dinosaur DNA,” then we might be sorely disappointed; however, we can’t help but wonder WHW we bring dinosaurs back to life and put them in close proximity to people. (SPOILER ALERT: things get eaten).

The Jurassic world in which we live has an appetite of curiosity. In some cases, our brains are still quite primitive. We do a lot of stupid things all the time that slip through the systems unobstructed. So, Mr. Chricton’s premise is actually extremely insightful, and is an extreme example of the primal nature that continues to run the world today. Not to mention, it’s extremely interesting. Extreme!

If you bought into the idea of adding more value to the things that we create, then we must also be aware of the underlying dangers that are already present.

WHW is actually responsible for some of the dino dung that we’re facing today. When we keep feeding our ancient reptilian brains with consumer urges, we just perpetuate the problem. WHW we make it bigger, faster, scarier? (SPOILER ALERT: things get eaten bigger, faster, scarier). Sometimes the consumer doesn’t know what’s best for itself; what it wants (or has been trained to want), isn’t always what it needs.

We need to run the scenarios in our heads first. We need to focus on what benefits the whole rather than what gets me more tokens. We need to then make those things happen.

When we get involved in the outcome, then we can get out of the “safety” of our voyeuristic tendencies that lead to destructive demands and curmudgeonist complaints.

We need a deep sense of community.

OUR Situation

Hello there
Hello there

The Obvious Ubuntu Relevance is right in front of our faces. That circle of friends is severely effected by the action or inaction of each member.

I have bought an Ubuntu device because it’s awesome, but what am I going to do with it?

I have joined an Ubuntu circle because I need community, but what am I going to contribute?

I know how to do these things. But, WHW I actually do something with this knowledge?

It’s cool to sit back and gain confidence—be rational—before producing something in the community, but it’s important that we don’t get stuck at the instructional stage. Furthermore, our contributions need not be that extreme!

Consistent application, experience, and collaboration should lead to progress.

StacyD’s DIY HiFi Headphones

The original plans for this project are by StacyD from “Does It Pew?”. She is The Maker of the original design and deserves full credit for this project. She’s awesome, so check out her stuff. Thank you, StacyD!

Below are the steps that I took to recreate this project according to my own understanding (which is pretty minimal). I’m sure that a lot of things don’t make sense from an engineering point of view. I won’t pretend that I know what I’m doing. That being said, these headphones sound fantastic and better than anything I have tried in the stores.  Please feel free to comment with suggestions to improve this design.

Method

1) Preparation (Headphones)
– Remove the ear pads from the headphones (they just slip off)
– Unscrew the front part of the headphones (3 Phillips screws)
– Unsolder or snip the original wires from the stock drivers, and remove the original wire.
– Drill ventilation holes into the back of the headphone cups
– OPTIONAL: sand and paint the cups (I couldn’t find a way to safely remove the cups, so I taped them up as they were and painted them very poorly. I ended up removing the paint and re-sanding them, which resulted in a cool steampunky copper color. I left them like that).

2) Wiring
– While you are waiting for your paint to dry, or otherwise, now would be a good time to start your new wiring. I used 2 colors of the wire, so that I could differentiate between the positive and the ground.
– Start with 2 x 12.5ft of one color and 2 x 12.5ft of the other color (4 strands of wire), and put one end in a vice, or tape it to something sturdy
– Star braiding in a litz braid style: Most right wire (4) goes over one wire to the left (3) to the (c) position , then the most left wire (1) goes over two to the right to the (c) position. Then keep repeating. This is the most time-consuming stage of the project.

– Strip the wire ends if you can. I couldn’t so I used a lighter to burn off the teflon coating, then wiped off the soot. There are seriously at least two or more tutorials on youtube about this.
– Twist the positives together and the negatives together so that you have 2 ends instead of 4. Do this on both ends of the wire.

4) Out With The Old
– The stock drivers were nicely glued into the baffle, so with a thin blade and some nail polish remover, I was eventually able to pry out the drivers.

5) Dampening Part I
a) Baffle
– I honestly had no idea where to put the rubberized foam, so I took a guess.
– Trace the baffle onto the foam (I chose red for clarity), and cut out the oval.
– Press the oval onto the baffle to make impressions of where you should cut holes. Then cut out those parts.

6) In With The New
a) Lock and Load
– Place the new SFI drivers into the baffles (smooth side down ie facing your ears). * I used 120omh drivers, which is all that I could find at the time. They require and amp to get the sound out (ie a portable music player barely gets enough sound out)
– Heatup some shapelock beads (I did this in a pan on wax paper… it stuck to the wax paper), and use them to secure the drivers to the baffle. In this case, be sure that you connect to the black plastic and not the red foam by pushing the shapelock down a bit. This will cause the foam to flare out.
– Then stick a vinyl/rubber pad on the center of each driver.

b) Universal Solder
– Feed the positive and negative wires through the wire hole in the cups, and tie a loose knot (the original wire had this knot, so I did that for tension relief).
– _Without burning yourself_ solder one pair of wires (eg red) to the positive diode on the driver (marked with red), and the other pair to the negative diode*.

7) Dampening Part II
– Cut out a circle of the dense felt and trim to fit the inside of the cup snugly. I cut a small slit for one of the plastic things in the cup to go through.
– Do the same for the softer wool felt and place it on top.
– Cut out a similar shape from 4 layers of tissue (I used toilet paper!), and cut o hole in the center for the vinyl pad on the driver to fit through.
– I added a strip of foam around the edge of the cups. I don’t know if this actually helps or hinders my design, but I thought it might do something.

8) Screw It: Putting it all together
a) Assembly
– Carefully screw the pieces back in place.
– Add some tape on the front (???) as shown.
– Put the ear pads back on

b) Universal Solder 2
– If you want to put any heatshrink on the wire, then now would be a good time to do it. I added two small pieces for the parts that connect to the headphones, and one long piece to keep the two tires together at the plug end (I now realize that it might not have been the best choice, as heatshrink kinda hardens when heated. I ended up not heating it… still thinking about what to do here.)
– Twist together the negative wires from both sides of the headphones. Now you have 3 ends to solder to the jack.

– Feed it through any additional heatshrink that you might want to add. I added a long piece to keep tho wires together as one, but didn’t heat it up.
– Feed the jack cover over the wires

– Solder the positive (red) wires from the LEFT headphone to the shortest tap on the jack.
– Solder the positive (red) wires from the RIGHT headphone to the 2nd shortest tap on the side.
– Solder the negative/ground (4) wires to the ground tap, which is the longest one in the middle.

– close up the jack with the cover.

9) Testing and Tweaking
– Test your headphones before heating up any heatshrink. I used a hair dryer to heat up the shrinky parts.
– These types of headphones apparently require a lot of tweaking to make them sound better. So far, I’m happy with mine and haven’t done any additional work. If you have any suggestions as to how I might improve them, then please let me know.
