Ben Katz’ Electric Tricycle

Ben Katz’ Electric Tricycle

One of the scooters at World Maker Faire that caught my eye was Ben Katz’ sweet scooter whose design is inspired by the Radio Flyer trike. Ben designed the tricycle around a brushless Turnigy motor, visualized the trike in Sketchup, welded, and machined the frame, and added a 40v LiFePO4 battery, motor controller, and gearbox. It can theoretically reach a top speed of over 45 MPH!

PocketNC, an Affordable Five-Axis CNC

PocketNC, an Affordable Five-Axis CNC

Jaws drop when makers see a five-axis CNC at work. That’s what happened to me when I saw PocketNC performing its magic. I peered closely and saw a spindle moving along two axes milling a piece of plastic mounted on a trunnion moving along/around three axes. The result of a three-year, four-prototype development effort of husband and wife team Matt and Michelle Hertel, PocketNC is getting ready for market.
