My name is Chris Hammond, and this is my website. Here you will find a selection of the random projects I embark on when I have a little bit too much
free time.
I'm a Computer Engineering student at the University of Michigan, and the power-electrical engineering leader on the UM Solar Car Team.
Most of the things
on this website (including the website itself) were done during high school; nowadays I spend too much time on the Solar Car to do anything
I can post here.
Of course, that should all change soon because I have all summer in Ann Arbor to build whatever ridiculous contraptions come to mind.

Holy crap I'm getting married!
[June 16, 2009 -- 9:33 pm]
Sorry my website has been in disrepair as of late. It's just, with Facebook and all, I don't really need you anymore.
Anyway, I just got engaged! I proposed to Kristine on her 21st birthday, at the Gandy Dancer in Ann Arbor. We've been together for 5 years, and I've known for a while that she's the one for me, but we always seemed way too young to get married. Now that we're both legally unrestricted and almost done with college, the timing was perfect. I can't wait to take on life's great adventure with her by my side!

Everything worked out!
[April 22, 2009 -- 7:42 pm]
I don't know if anyone even reads this thing anymore, but I figure if anything deserves posting, it would be this.
I got an internship for the summer, and it's awesome! Previously, I was screwed by the economy and Toyota's deadlines, but everything worked out for the best because instead of working at some lame office I'll be at
Pratt & Miller.
:D
Oh yeah, I can call my car to start it now.
[March 3, 2009 -- 10:46 pm]
So yeah, I got my cellphone car starter working. It's in version 0.1 Beta right now though; it doesn't have any security features or do anything besides start the car when you call it. Also, I don't have anywhere warm to take apart my dashboard for a power connection, so I just taped it to a battery and dropped it in my center console. Incidentally, it looks like I have a bomb in my center console now. I'll post pictures and a worklog later.
Why not some updates?
[January 28, 2009 -- 11:47 am]
I apologize to my loyal readership, who I'm sure have been wearing out their F5 buttons refreshing my page over and over again, waiting for an update.
Anyway, the Death Laser project has been stalled for a while, mostly because I'm too discouraged to try buying another diode, and I found 2 other projects to occupy my time.
I finished constructing a Lithium-Ion battery pack for my bike, out of necessity after the Lead-Acid one shorted out and destroyed itself. I haven't completed building a charger for the pack yet, because it is too snowy to use the bike, and I found another project to occupy my time.
So I got a remote starter installed on my car over Christmas break (thanks Kristine!), and I also got a
PIC-based cellphone development board. My current project is to combine the two into a cellphone-based car starter, that I can call from anywhere I happen to be and start my car by entering a touch-tone password.
Perhaps when I finish this project, I'll throw up a worklog so others can follow my lead. It seems like I could make millions selling something like this on the mass market, but right now it just consists of two off-the-shelf systems, one programmed to control the other.
Countdown to being 21:

Fucking fragile laser diodes.
[August 24, 2008 -- 6:04 pm]
So my Death Laser is really close to being done. I was literally a few grams of glue away from having a complete laser when I burned out the diode.
My battery pack, enclosure, and constant-current power supply are all perfect, but I have to buy another diode (I think this is number 4) before I can finish it.
Oh, I've also been toying with the idea of a Lithium battery pack for my electric bike. Maybe I'll even post a picture of it at some point.
The Race -- Owned.
[July 24, 2008 -- 6:39 pm]
Winning feels good.
Winning by an entire race day feels better.
This has been the most amazing thing I've ever been a part of, and likely will be for a while. It taught me, among other things, the importance of "Not Fucking Around." We were NFA in everything we did, and it certainly paid off. We spent 15 minutes on the side of the road the entire race, and it was because the CAN connector on our MPPTs (one of the few electronics we didn't design ourselves) was poorly designed. We were ready for virtually anything to go wrong on the car, with a spare ready to swap in, and a spare for the spare. If we had had Principia's DC-DC converter failure, n
