[Chris] has been hard at work building a Heads Up Display into some Snowboarding goggles. We’re used to seeing the components that went into the project, but the application is unexpected. His own warning that the display is too close to your face and could cause injury if you were to fall highlights the impractical nature of the build. But hey, you’ve got to start somewhere when it comes to prototyping. Perhaps the next iteration will be something safe to use.
A set of MyVu glasses were added to the top portion of the goggles, which lets the wearer view the LCD output by looking slightly up. The display is fed by a Raspberry Pi board which connects to a GPS module, all of which is powered by a USB backup battery. In the video after the break you can see that the display shows time of day, speed, altitude, and temperature (although he hasn’t got a temperature sensor hooked up just yet). His bill of materials puts the project cost at about £160 which is just less that $250.

If you own a cabin in the mountains of British Columbia what do you do during the warmer summer months? Well, we’d probably mix of a cocktail and string up a hammock, but [Darrin] is quite a bit more motivated. He planned for the snowy season by building his own ski lift. He shared the details in a forum post, but you’re going to have to register and wait for approval before you can view that thread. Perhaps you’ll want to look at the video after the break before making that kind of commitment. Normally we would just pass over projects that require a login to view, but this one deserves the attention.
The setup is essentially a very steep tow rope. 1600 feet of 1/8″ aircraft cable covers an 800 foot span of his property. Apparently he’s got a total of 1000 feet of vertical drop but the lift doesn’t cover the whole area quite yet. That 6.5 horsepower Honda engine drives the cable loop, with the pulley system seen above used as an RPM reducer. Each skier can hook onto the cable used the nylon rope with a ski-pole spacer and a hook. The RC vehicle remote control works as a dead man’s switch, starting the lift slowly when the throttle is depressed and stopping it when released.
Normally we like to link to similar projects, but so far this is the only ski lift we’ve covered. You’ll have to settle for this ski-pole mounted POV display.
