The Low-Power Challenge Sees High Effort 💪

With a few weeks left to go, there's still time to get your entry in! [3602421454791242043.png] Wednesday, March 1, 2023 [Aloidia Solar-Powered Keyboard Outshines the Rest »]( The Low Power Challenge Is Still Going Strong There's just a few weeks left to go in the 2023 Low Power Challenge, which runs now through March 21st. Up for grabs are three $150 Digi-Key gift certificates, so if you haven't already entered, there are a few weekends left for you to bust out that soldering iron and scrounge up a few coin cells. [2022 Hackaday Low-Power Challenge]( They say that one of the keys to creativity is restriction, and that's the name of the game here. How long can you make a coin cell last? How low can you go when it comes to powering a thing? You get the idea. If you need some inspiration, we have several honorable mention categories this year -- Sensible Sensors, Artful Art, Battery Buster, Perpetual Motion, and Just How Low? While most of these are self-explanatory, [take a look at the contest announcement post]( for more details. Are you more of the visual type? Keep scrolling to check out some of the great entries we've already seen so far. Highlights from the IO POPULAR BITS [project thumbnail]( [LED Coaster Is Poster Child for Low Power]( Although LED drink coasters are about as novel as ice-coled beverages themselves, this clever design uses a supercapacitor and charges wirelessly. Don't worry, everything is encased in resin, so condensation is no cause for consternation. [project thumbnail]( [LED Dice Badges Are Primarily Low-Power]( How'd you like to wear a bit of randomness on your shirt? That's the idea behind these dice badges, which last many months on a single coin cell. A hidden button moves the dice through six different modes, including a random number display. [project thumbnail]( [PotatoP Laptop Is Anything But Potato Quality]( How'd you like a laptop with battery life measured in years? [Andreas] sheds some ambient light on the subject with this contest entry. Hack Chat LIVE CHAT WITH LEADING EXPERTS EVERY WEDNESDAY [Today: Life at CERN Hack Chat]( Daniel Valuch will host [this week's Hack Chat](. Work is usually just work, but there are some gigs that must really be fun to go to every day. One place that must be kid-in-a-candy-store stuff for any engineer is CERN, the European Organization for Nuclear Research, where the biggest of Big Science is done every day. Electrical engineer Daniel Valuch has worked at the storied institution for nearly 30 years, and he's going to tell us all about life working at CERN.
