The video above is the final working DIY Segway from [sb-scooter]. The website and build log don’t have a lot of information at the moment, but you can still gawk at several pictures of the construction (and a picture is worth 1000 German words).
For those looking for the nitty gritty, with some quick math we figure its two 500 watt motors, powered by 12Ah batteries, will last about 90 minutes. If you’re looking for more details or to build your own, you’re as lost as we are.
[XenonJon] got a lot of attention for a skateboard/segway style balancing platform he took to the Makerfaire in Newcastle. He decided to try to build it the cheapest and easiest possible way in an attempt to help others build their own. The build is documented very well, however you have to email him to request the code for the Arduino. Maybe after enough requests, he’ll just pop it online. We thought this looked familiar, so we searched the archive and found this very similar setup from back in 2005. Unfortunately, that project page appears to be gone now.
[Mark] wanted a Segway but why buy something if you can have more fun building it? His end product is an amazing homemade version of the self-balancing transportation package. We’ve seen several projects that include auto-balance, but this one is large enough to ride on and has a bit of an advantage in the design. The motors, batteries, and other components are mounted below the wheel hubs and are weight balanced. This means that the device wants to find balance naturally, even when the electronics are switched off.
The frame was modeled in CAD and then welded together. For propulsion [Mark] has installed two 750 Watt motors which will use sprockets and chains to turn the wheels. The machine balances based on data from both a gyroscope and an accelerometer, with the entire packaged tied together using an Arduino.
[Mark’s] build log is well laid out and details each part of the build with a different post. His two most recent entries include video of the unit balancing and of him riding the 95% completed project. A big thanks to [Mark] for taking the time to document this so that we can share in the excitement of a well-executed project.
When [Epokh] sent in this Wii controlled segway style bot, we remembered a post a few months ago where someone made a balancing bot, but hadn’t completed the Wii code. Well, [Epokh] is going to show you how to implement the Wii controls with the Lego NXT system. He’s found the links to all the software you need and broken down the configuration step by step. He’s been busy lately, let’s hope he keeps it up.
[Kerry] is building a segway type vehicle for a senior project. Though it doesn’t appear to be done yet, there is some good work finished. As with any balancing bot, it relies heavily on input from a gyroscope, and at least in this case, an accelerometer. That data can be very messy. The sensitivity of the sensor means that people often end up with vibrating or drifting in their projects. [Kerry] has put some work into finding a method of smoothing that results in fast, accurate, but smooth reaction. You can see a video of some comparisons between methods after the break.

[Joe L] sent in the Arduway on the tipline. It is a robot made of Arduino and Lego NXT components based on the Segway. A software library to control LEGO NXT motors and a few sensors he used is available on SourceForge. This robot does a good job of balancing itself while moving forwards and backwards.
There is a YouTube video of it in operation after the break.

I admit it. Most the weekend I was making quips about the Segway polo guys like, “Those guys look like walking would do them some good, especially that one.” Well, Will and I finally put two and two together and realized that “that one” was Steve Wozniak, co-founder of Apple. He is feared on the polo ground because he has got at least three backups with him and doesn’t mind breaking one.
