Mecanum wheels are a nifty invention that lets a vehicle drive sideways by attaching small rollers to the outside of the wheel, angled 45 degrees off the main axis of rotation. I’ve always wanted to play with them, but could never justify the cost of buying them pre-made. Each wheel alternates the angle of the rollers, so when they counter-rotate, the vehicle can drive sideways. Forward, backward, and diagonal translation are also possible, as well as skid-steering-style rotation. Though fun…

Once built, playing around with options like multicolor or multimaterial printing should be fun! Although an imposing project to start, I was surprised to get such good mechanical performance from the design. Most of the print challenges in early testing can…

Rationale for a Minimalist Backcountry GPS

Rationale for a Minimalist Backcountry GPS

The purpose of the GPS is to: – supplement map and compass as the primary means of navigation. – as a measure of safety when my skill or mental state might be good enough for the circumstances.

Skurka’s note: http://andrewskurka.com/2012/why-backcountry-gps-units-are-overrated/ http://www.rei.com/learn/expert-advice/compass.html Desired GPS Features: – Display location such that I can find it on the map. – Pre-load waypoints…
