DSO Nano Displaying Flashlight Pulse Width Modulation

Thu, 02/14/2013 - 1:32pm — Aaron

Just a short video of me screwing around with the DSO Nano and my Leatherman Serac S2 flashlight.

Hacking an Extra Rechargeable NiMh Cell onto an "Alkaline Only" LED Circuit.

LED with Alkalines

Celeste bought some LED lights for my bike trailer this winter (as the second half of my commute is always in the dark). They were about $20 at target and come in lots of cool colors.

They run on 4 AA batteries. I didn't notice the fine print on the packaging until we got them home and I put a bunch of Nimh rechargeables into them. The lights were horribly dim. I looked at the fine print and it basically said, 'don't use rechargeable batteries.'

iOS hardware limitations discourage long tail innovation

Thu, 11/11/2010 - 3:11pm — Aaron

CSU recently hosted an iOS app development seminar with a couple apple representatives. One was clearly a sales guy, the other was the guy who spoke code.

It was interesting. I learned quite a bit about building a basic 'Hello World' application. In the end, the tech is no different than any other I've learned. (though objective-c syntax is a bit unusual compared to the other c based languages I've met.)

So, all that is fine, but I started to get a crappy feeling in my stomach when I asked this question:

Why I love the Thinkpad #37

Sun, 02/17/2008 - 11:24pm — Aaron

I needed to take apart a my precious Thinkpad today. (The poor thing is getting on in years, and I needed to swap out its CPU fan.) It struck me as I was taking it apart. (something I've done many times) I don't know of any other puter manufacturer that makes it this easy on you. This is a primary reason I love the Thinkpad. It's like the Jeep of computers. Simple, easy to service, uses basic, standard parts and screws.

Hackers are an Insignificant Minority

Most people don't care that the iPhone is closed. They don't even know what the difference between open and closed is. And they most certainly don't care.

The iPhone is a phone. It was designed to address problems with phones. The problems it tried to address mostly had to do with the fact that cellphones are almost unusable. For example, I have no idea how to use most of the features on mine, and I'm a geek. It doesn't bother me.

Arduino Time Lapse Photography IV

Sun, 05/27/2007 - 4:37pm — Aaron

Not much to say here, this is the final result of my latest attempt. Took about 20 days or so. I've still got the camera in place, and I'm going to leave it shooting until that bloom falls off.

The results are in! (well, offloaded from the camera anyway.) This one turned out much better. Much more consistent.

there's a bit of an unfortunate shift at the end where the bloom we really want to see gets a bit cut off, but the movement is really cool!

Partial results are in! They more or less suck.. ; )

I initially set this system up and had it shoot in our living room, on a wobbley tv tray with no flash. (I figured my wife wouldn't be happy about a clamped down monstrosity and a flash going off in the dark every 30 minutes.. turns out, she's fine with it!)

I've been building this thing for quite some time. For the last 2 nights or so, I spent some time finishing up version 1. It is now functional. (and has taken 23 or so pictures of my desk plant in the last couple hours)

Photos of the rig (with notes pointing out the parts) can be found here: http://www.flickr.com/photos/abandc/sets/72157600201419395/

How a Shower Toilet Works

Sun, 03/18/2007 - 7:13am — Batty

I made a little video explaining how those fancy-schmancy shower toilet bottom washers works. I hope that this will be the last of my poop-themed videos, although I am in Japan, and you know what they say about Rome and their scat-porn...

Or is that just about Japan?
