I found this video tonight. Its a very stunning video of a ride that Top Gear’s James May took in a U-2. Its really worth watching.

New Night Sky Pictures
Here are my latest night sky pictures. I took these December 10, 2009. The brightest with the star streaks was about a 30 minute exposure. The rest were around 15 second exposures with varying apertures and iso settings.

First Snow of Winter ’09
These are some pics of lower Middle Tennessee’s first Winter ’09 snowfall. Not much but at least 1-2 inches when done. Sewanee probably got 3-4 inches.

I realize the second is a little out of focus. I hadn’t realized it was on manual.

Time Lapse Video
I completed my first ever time lapse video with my web cam today. It didn’t turn out too bad, though you can really tell I have it on the inside looking through a window and screen.
I setup this webcam to upload an image once a minute to my linux machine. Once I had all the images, I ran the script below. It takes all the images generated and names them sequentially.
ls *.jpg | nl -nrz -w4 | while read a b; do mv "$b" $a.jpg; done
Once you have all the image files named correctly, you can run ffmpeg. I’ve included my sittings here.
ffmpeg -r 10 -b 2048k -bt 768k -i %04d.jpg out.mp4
Equipment/Software:
- D-Link DCS-920
- ffmpeg

Fall Creek Falls October 25, 2009
Today, we took a minor excursion to Fall Creek Falls to see the leaves changing. It was the first time that I’d been up to that area. Overall, everything was timed about right ending with the sunset photos, you see near the top of the picture list below. Continue reading →

Applying DD-WRT to a Linksys WRT54GL Router
My ancient D-Link 624 has showing signs of conking out over the past couple of months. That had put me in the dilemma of “Do I wait for 802.11n to be released or do I buy a modifiable router now?” Well, I made the decision. I bought an old, high modifiable Linksys WRT54GL.
***Just a word of caution, don’t buy a WRT54GL unless you plan on flashing the firmware to something better because the default firmware sucks royally.***
This morning, I successfully applied the latest DD-WRT firmware to the router and now have it up and running. So far, I am really digging it. I highly recommend it to anyone with supported hardware. I choose DD-WRT over OpenWRT simply because of the ease of upgrading it. Eventually, I may switch over, but as of now I have no plans to.
This procedure is not without risk however. If you screw it up, you could find yourself with nothing more than an expensive doorstop/paper-weight/what-have-you. If you follow the instructions provided on the site you will most likely succeed.
If you would like to attempt to modify your router firmware, go to http://www.dd-wrt.com/ and check to see if your hardware is supported. Definitely check the Instructions because you will brick your router if you mess up. Also check out the “Peacock” thread in the DD-WRT Forums. It can be found here: http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486. I followed the exact procedure listed in the first post and had absolutely no problems.
a.Set your computer to a static IP of 192.168.1.8. (or to whatever subnet the router is on) Disable all firewalls and security. Disable wireless on your computer and only have the router connected to the flashing computer by the ethernet cable between the two.
b. Hard reset prior to flashing. Wait. Check for password page on re-login and change password.
c. Flash firmware. You can use the webgui except if you have a belkin router. (For belkin use tftp.exe to flash)
d. Wait…at least three minutes. Lights should return to normal. See important2, below. Failing to wait is how most people brick their routers.
e. Do a power cycle of the router. (Unplug the cord, count to 30 and plug it back in.)
f. Wait for the lights to return to normal usually about 2 minutes.
g. HARD reset again. Wait. Check for the password page and re-login to change the password. Then you can reconfigure your settings manually.
h. Once configured set your computer back to autoIP and autoDNS.
Attached below is a video I watched before doing it. It really simplifies the procedure and you really need to read more into it, but it should alleviate some fears.
