World’s Smallest LED Blinky

[Mike Harrison] is known for incredibly tiny soldering. Now he’s claiming a “world’s smallest” in the form of a stand-alone LED blinker, and we think he’s got the record.

He brought it along with him to Friday’s Beagleboard Bring-a-Hack, and we got a close look at the diminutive assembly. The project was dreamed up when [Mike] saw an announcement from Seiko about a new supercapacitor in a tiny package (likely the CPH3225A giving the blinky a footprint of 3.2 x 2.5 mm).

The Perils of Developing the Hackaday Superconference Badge

In case you haven’t heard, the best hardware conference in the world was last weekend. The Hackaday Superconference was three days of hardware hacking, soldering irons, and an epic hardware badge. Throw in two stages for talk, two workshop areas, the amazing hallwaycon and the best, most chill attendees you can imagine, and you have the ultimate hardware conference.

Already we’ve gone over the gory details of what this badge does, and now it’s time to talk about the perils of building large numbers of an electronic conference badge. This is the hardware demoscene, artisanal manufacturing, badgelife, and an exploration …read more
