We have now the next in what seems to be becoming a series of reviews of the new question and answer site Akatoo. May just ended, which means that the month’s promotion also ended. I finished in third (or maybe fourth) place on the leaderboard as ranked by promotional points gained in the month. To the top twenty at the end of the month go iPod nanos, and to those ranked 21-70 go iPod shuffles. April’s contest winners posted on the site at the beginning of May that yes, they did get their iPods in the mail, so I was satisfied but not surprised when I received an email at the end of May 31 asking me to provide a shipping address to an email address at the Akatoo domain. I did so, and come Monday June 2, the next workday, I received an email back asking for a phone number, as the Apple site required one for shipping (from which I gather that they order them from Apple at the end of each month and have them sent directly to the contest winners rather than via themselves).

I sent that information back that afternoon. Come the morning of Thursday June 5, FedEx left a note on my door to let me know that they tried to deliver a package but couldn’t get the required signature (I was sleeping at the time). I signed the slip and put it back out, and come Friday morning, the package was waiting for me when I awoke. In it was, as expected, an iPod nano–silver, 4 GB.  Quite like the one on the far left here.  I opened the shipping box, but haven’t removed the iPod from its case yet. I’m not certain of I want to keep it, or bring it somewhere and get store credit for something else or to upgrade to a larger version. I wouldn’t be surprised if I ended up on the leaderboard at the end of June as well (I’m sitting at #7 now, having hit #2 and then lost internet connection for a while), and two nanos could well equal a bigger and better model.

So for anyone who’s wondering, I can confirm that yes, Akatoo does give real, legitimate prizes for its monthly promotions.

I finally got around to repairing (again) my headphones.  As I noted, after the cord snagged on a chair, the left and right channel wires broke from their contacts, though the ground was still attached.  I kept meaning to fix them, but then I got used to the earbuds that originally came with the iPod.  They were by no means as good as my real headphones, but they did the job, and I was lazy.  Yesterday, however, they inexplicably lost the right channel completely, and it quickly became time for the repair job.

The physics electrics lab wasn’t there to supply me this time, but my brother was, so I borrowed his soldering equipment.  The first step was to remove the solder from the last repair job from the contacts, since I was reattaching it to the same plug.  Instead of the copper wire that we had last time, he had a handy little pump thing.  You primed it by pressing down on a plunger, then touched the tip to the heated solder and pressed a button, thereby sucking the solder into the depths of the device.  (After a quick google, I’ve found that it’s called a “solder pump,” or the somewhat sillier “solder sucker,” and looks like this.  The wire we had before is a solder wick.)  Since we had no reason to use the solder wick, I can’t compare the two.  I can say, however, that the solder pump worked pretty well, removing the majority of the old solder.  It did leave a sort of solder sheen on the surfaces, but that wasn’t a problem.

Then came the same process as last time, with a few modifications.  First was how I dealt with the tension relief, the fibers around which the wires were wrapped.  Last time, my roommate unwrapped the wires, cut out the tension relief, and then twisted the wires back up.  I tried that at first, but I’m apparently not as skilled as he is, and I ended up with scraggly looking wires that weren’t working well.  I stripped some more of the plastic coating and started again, and this time didn’t bother to unwrap.  I just burned off the painted insulation with a match, which I think probably burned out some of the tension relief as well.  Undoubtedly, most of it remained, but it didn’t seem to be a problem.

Unfortunately, I did have to go through the “making sure the channels are right” procedure again, and once again, I had them wrong the first time.  This time, though I wrote down which way they go, so I can do it right if I need to do it again.  On my headphones, at least, the red wire goes to the longer contact, the green to the shorter.  It was also easier to switch them and get them back through the holes of the contacts because I had some very fine-tipped tweezers.  A helpful tool, those.

Finally, this soldering iron was a bit trickier.  The first one was adjustable by a dial, so it could be set however.  This one could be set as either low or high.  Low wasn’t working, so I flipped it to high, but that was still problematic.  heating the surface and touching the solder to that, as I was taught, wasn’t working, so I ultimately had to melt the solder onto the soldering iron and then spread it around on the surface that way.  It gave me a workable join, and the headphones sound perfect, but it did result in some large and unwieldy solder lumps.

All in all, I’m glad to have my headphones back, and I’ll look out for attacking chairs from now on.
