3D Printers have been in the hands of hackers for well over ten years, but the dream is far from over and certainly not overslept. This year’s Midwest RepRap Festival is a testament to the still-growing excitement, and world where 3D printing is alive and kicking on the next level. …read more

The Trenton Computer Festival (TCF) doesn’t have the name recognition of big technology conferences like DEF CON or HOPE. It’s not even as well known as smaller more localized conferences like DerbyCon, ShmooCon, or the Hackaday Superconference. In fact, there’s a good chance that most readers have never even heard of TCF. But despite not holding a place in the hacker lexicon, TCF has plenty to boast about. Its played host to technology luminaries from Bill Gates to Richard Stallman, and now in its 43rd year, holds the title as the longest continually running technology festival in the world.

Electric current comes in many forms: current in a wire, flow of ions between the plates of a battery and between plates during electrolysis, as arcs, sparks, and so on. However, here on Hackaday we mostly deal with the current in a wire. But which way does that current flow in that wire? There are two possibilities depending on whether you’re thinking in terms of electron current or conventional current.
In a circuit connected to a battery, the electrons are the charge carrier and flow from the battery’s negative terminal, around the circuit and back to the positive terminal.
Conventional …read more
[Kenjo] attended Chicago’s Thotcon this past week and has started hacking the convention badge and detailing what he learned. Thotcon’s badge, designed by [Jedha] and programmed by [John Wallis] of Workshop 88, is packed with the requisite electronic hardware and cryptic clues. There are four NeoPixel LEDs, three pots, and a micro USB, all run by an ATmega32u4.
The stock firmware is a game called tesserHack, a maze game using the three pots for navigation. You can also connect via USB to play through the serial console, and this version includes a map view and help menu.
[Kenjo] who previously …read more
