Thanks for the suggestions. However I'm not necessarily looking for a new project. I've already going to be making the automatic drink mixing machine, and I need to make a home kegorator. On top of that I'm contemplating the idea of making a home made pinball machine.
For now I'm looking for examples of cool geeky projects people have devoted their time to.
Here's another example.
This guy devoted his time to building a home made segway, and if that wasn't enough he decided the segway was to redundant (with it's second wheel), so he made a self balancing unicycle. Here's the link to his site: http://www.tlb.org/scooter.html
I actually have a home-built Keg-o-rator. It is a minifridge and it holds a five gallon keg. Once you find the home brew shop in your town or online and get all the needed parts, this is a quick and very easy project. Here are a few tips to remember once you get into this project:
-Buy extra hosing. Hoses rot, get nasty, and generally go bad in about a year or so. Hose is cheap, so don't wash it, just replace it. Buy extra when you make your initial purcahse, it will save you the hassle of trying to match it and buy more later.
-Insulate your dispenser tower. You know, the chrome thing that sticks up and has the tap attached to it. I used some flexible plasticy foam stuff and it works great. Remember, there is a hole on the top of your frige leading into the tower. Insulating the tower will do two things. 1. Save energy/cash and 2. keep the beer in the hose that is inside the tower cool (other wise that first sip could be nasty).
-Buy and check a thermometer for your fridge. Cold beer is great. I keep mine at about 35 degrees, but 32 degrees or lower could cause some major problems.
-The CO2 unit on your keg-o-rator can "force carbonate" your beer. You will need to learn to do this AND you will need to learn how to set your CO2 level properly. You can ask me about this, the pro at your homebrew shop, or read about it. But you want to avoid 2 things 1) Overcarbonating your beer (Most people are not fond of 4-5 inches of head on their beer) and 2) blowing gaskets. You only want to use the minimum amount of CO2 pressure on your keg. ANd if the keg is already carbonated when you get it (and generally they are to some extent), you will not want to turn on the CO2 at all until the pressure in the keg reduces. You can just open the tap and beer will come out on it's own.
-keep a good beer in your keg-o-rator. I realize Natural Ice is only $20 a 5 gallon keg, but no one really wants to drink that swill. Especially over a long period of time. Spend the extra dough and get your favorite.
-keeping a coin bank atop the keg-o-rator to collect a beer fund is the best possible thing you could do, especially if a lot of people (non-family) are drinking from it.
If you need anymore pointers on keg-o-rators, let me know. They are fun, but must be respected.
