Obligatory tech tree

It’s hard to let a Christmas go by without looking in on a geeky Christmas tree project. Luckily, [Peter Davenport] decided to share his Arduino and LCD shield tree.

Blinking USB dude

If you’ve got a 555 timer and some commonly salvageable components give this blinking LED man a try. The version above is USB powered but that’s just to take advantage of the 5V regulated power.

Propeller business card

[Jay's] business card is packing quite a punch with this Propeller microcontroller. We love seeing electronics design in cards (however unrealistic the price and portability may be), and this is a big processing upgrade compared to the Tiny85 based offering.

Flying high in NYC


We leave you with a spectacular view of New York City. This breathtaking footage is just as fascinating as the first videos we saw from these folks.

Ritewing Zephyr build and flight footage

That’s a camera perched atop this aircraft’s wing. [Trappy] built the video system into his Ritewing Zephyr and his test flights in the Austrian Alps make for some breathtaking video. The foam wing is pretty easy to work with and the tool of choice here is a hot knife to cut out cavities for the electronics. The total build time came in between ten and twelve hours, but this isn’t the first time [Trappy] has worked with this model. We’re not sure what setup he’s using for control, we’d guess something head-mounted, but do take a look from the cockpit after the break. You’ll like what you see.

[Trappy] informed Hackaday that he’s planning some altitude and distance testing next weekend. The goal is to reach 15,000 feet and a range of 12 miles.
