The tools you will need to build this segway are:

Wood saw, hack saw, drill, drill bits, hammer, screwdrivers, wrenches, wire strippers, soldering iron, files, metal punch

These are the mechanical plans that the writer used:

This is the electrical wiring schematic:

Here are the segways features:

• Easy to build with no welding, no complicated steering linkage and minimal soldering.
• Uses a readily available $3 digital MPU6050 accelerometer/gyro IMU board.
• Total parts cost is under $400 (including shipping). A real Segway is $5000!
• No salvage, dumpster diving or Craigslist parts.
• A detailed parts list and ALL purchasable sources are included.
• Well documented with over 50 minutes of HD how-to video, pictures and a detailed plan.
• Uses the very common Arduino UNO processor board.
• All Arduino processor code is included. NO additional Arduino libraries need to be installed.

It involves:

• wood working
• metal working
• plumbing techniques
• wiring from schematics
• micro controller (Arduino) C like coding
• accelerometer/gyro basics

There are many steps in this process for building the segway. Yet, it is definitely worth it! There are approximately 36 steps!
