How Do You Stream Live Sports?

How Do You Stream Live Sports?

Cutting cable isn't too hard—unless you watch sports, in which case it's a nightmare. Huh989 over at Hackerspace wants to know: how do you stream sports, and are the sports packages out there worthwhile?

Three Creative Uses for Old Denim

by David Allen

denim

Do you have some old blue jeans hiding in the back of a dresser drawer, ignored, and unworn?  Check out these repurposing projects and make room for some new clothes!

First up is a quick and easy hair bow made from denim.  In addition to the old blue jeans, you’ll need scissors and needle and thread.

Our next project is a little more complicated, but the resulting denim purse is worth it.

Finally, here’s a neat little iPod case you can make from the scraps of the two previous projects.

Twenty two servos and an awesome clock

by Brian Benchoff

servo

We can never get enough interesting clock builds, and [ebrithil]‘s servo clock (Deutsche, Google translation) is up there with the best of them. There’s twenty-two servos in this clock, moving time forward with the mechanistic precision only an Arduino project can.

The digits in [ebrithil]‘s clock are constructed like seven-segment displays, only instead of lighting up LEDs, servos turn small bits of paper that are light on one side and dark on the other. Turing the servo 180 degrees changes each segment from one shade to the other, making for an electromechanical seven-segment display.

The servos are controlled by an Arduino Mega connected to a DS1302 real-time clock. One problem [ebrithil] had with this project is having the segments rotate slightly every time someone turned on a light attached to the same circuit. He solved this problem by running the circuit off a perpetually charging cell phone battery, allowing him to take this clock on the go without losing time.

Showing off a high-performance brushless motor camera gimbal

by Mike Szczys

Here’s [Tom Parker] showing off a brushless motor gimbal stabilizer for his GoPro camera. We saw a similar project a couple of weeks back that featured a 3d printed quadcopter mount. This offering is meant to be held in your hands. It keeps the subject in frame even if the cameraman’s hands pitch and roll (we figured aeronautical terms were best here). This image shows him demonstrating a level camera as he quickly rolls the frame from one side to the other. It doesn’t compensate for yaw, which is something he may change in the next iteration. We already like the results he’s getting with it.

About 3:15 into the video demo below we get a very quick description of the build itself. He started it as a project at University. Fabrication included work on a 3D printer, laser cutter, and vacuum forming machine. The grips are bicycle handlebar components. To overcome the stabilization system the operator has access to a joystick. Without this you’d never be able to aim the camera up or down because of auto-leveling.
