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.
Saw that RC vid I think via ./ and while it’s ultra cool possibly not much of a hack, more of a professional production with lots of experience, testing, planning, and involvement by the authorities so the DHS wouldn’t come down on him for it.
Saw Jay’s business card over at the Prop forums. Thought he was being a bit paranoid over the cell battery, the prop is clearly rated to run down to 2.8V and if you run it on RCSLOW (native slow oscillator, ~20 kHz) it runs at even lower voltages and draws microamps.
