This comes in from reader John Stone, who created his own guide on how exactly to go about designing and building your own treadmill desk. John was good enough to write a blog post detailing parts needed, how to choose a treadmill, and build steps over at his blog, Node Floating.
Touted as a “simple standing treadmill desk”, it does seem to be very functional, and gets the job done at a low price point (just a few dollars, besides the obligatory treadmill itself). An added benefit is that it is portable–able to be easily removed at will from the treadmill unit when not needed. This design also has no need for specialized bottom-only treadmills, which is what a lot of full-size adjustable standing desk designs call for.
