Hackaday editors Elliot Williams and Mike Szczys sift through a week of excellent hacks. Big news is of course the Raspberry Pi microcontroller which Elliot had a few weeks to play around with on the bench before the announcement — it has some fascinating programmable modules (PIO) built in! Philips designed an LED light bulb that under-drives the LEDs for efficiency and long life. And Amazon added a nice little hardware disable circuit for the microphone in the Echo Flex — a rather extreme teardown shows how they did it. Plus we talk about an open source long-range RC protocol, wall-sized pen plotter art, and a 3D printer that angles the nozzle to avoid needing support.

I’m currently watching the SDR video. Just finished the part on hardware and about to listen to the software section. Thanks for highlighting that Remoticon talk.
Woot! My pleasure.
