The latest DIY ideas, techniques and tools for bikes, rockets, R/C vehicles, toys and other diversions.
MAKE subscriber Steve Hoefer sent us a link to this fascinating piece on retro-direct drives for bikes. Not really sure how practical it is, but the engineering is interesting. And, it’s probably a great way to work different leg muscles. What’s a retro-direct bike? At the beginning of the 20th century, although derailleurs and geared […]
MAKE reader Sophie sent us pics and details of a bike her boyfriend Eric converted to a motorized bike. Eric writes of the build: The first part off this project was to restore an old Schwinn Cruiser I found. I stripped it down to the frame, took off all of the old paint, and sprayed […]
I was unaware of the lovely couch bike phenomenon until my old landlord, Billy Gawrych, sent around this first image of two enterprising fellows taking this couch bike for a spin through the drive through. After an obsessive internet research session, I had amassed a compendium of couch bikes, for you to see in one […]
The Lego Logic Blocks project appears to only be theoretical, however the idea behind it is pretty neat. The goal is to make a set of logic gates that use light as inputs and outputs.
The plot was to make the lightest, slimmer, and with the minimum lego pieces iPad stand. And the result is this one. Made with just 11 pieces of lego, and foldable.
The first entry in our Gadget Freak Design contest is in, and it’s a doozy: Matthew Katzenstein created this sweet 3×3 RGB LED matrix, controlled by an Arduino Diecimila, that plays a game of blue-vs-red 3-dimensional tic-tac-toe. The video, above, is lengthy and quite detailed. You can watch it work at 5:30 (it should automatically start there if you click above); the whole video can be seen here.
Our pal Fra Fondi, who’s keeping an eye out for us for R/C-related content, in support of our Volume 22 release, sent us this link. The Gadget Show cast seems perhaps a bit too scripted with the over-the-top enthusiasm, but the R/C cars, the jumps, and the record-breaking are pretty cool. Vorza Flux HP RC […]
