DIY Segway - Bill of Materials
Rev. 1.0, 8/23/2007
Does not include fasteners/hardware, wire and connectors, etc. Just too much to keep track of and most of it we just had lying around the shop. Shaded items are items we either obtained for free or already had on hand.

It’s too hard to add up the total cost. Straight from what’s listed above, it is just over $1,000. That does not include fasteners, wire, connectors, etc., which would add a bit to the cost. However, we got a lot of stuff for free or had it lying around from FIRST (including the shaded items on the list), so we actually spent much less than $1,000.
If you’re attempting a project like this, chances are you are the type to also have some stuff lying around that could be useful. So in all, a reasonable estimate for the project cost is $1,000.
