LayerOne Hardware Hacking Village

Go to DEFCON and you’ll stand in line for five hours to get a fancy electronic badge you’ll be showing to your grandchildren some day. Yes, at DEFCON, you buy your hacker cred. LayerOne is not so kind to the technically inept. At LayerOne, you are given a PCB, bag of parts, and are told to earn your hacker cred by soldering tiny QFP and SOT-23 chips by hand. The Hardware Hacking Village at LayerOne was packed with people eagerly assembling their badge, or badges depending on how cool they are.

The badges are designed by [charlie x] of null space labs, one of the many local hackerspaces around the area. The design and construction of these badges were documented on the LayerOne Badge project on hackaday.io, and they’re probably best con badges we’ve ever seen.

There are two badges being distributed around LayerOne. The first is an extremely blinkey badge with a Cypress PSoC4 controlling 22 individually addressable RGB LEDs. Most conference attendees received a bare PCB and a bag of parts – the PCB will get you in the door, but if you want your nerd cred, you’ll have to assemble your own badge.

There are still a few interesting features for this badge, including an ESP8266 module that will listen to UDP packets and drive the LEDs. Yes, a random person on the same WiFi AP can control the LEDs of the entire conference event. The badges can also be chained together with just three wires, but so far no one has done this.

The second badge – for speakers and staff – is exceptionally more powerful. It’s a Linux box on a badge with two Ethernet connectors running OpenWRT. For a con badge, it’s incredibly powerful, but this isn’t the most computationally complex badge that has ever been at a LayerOne conference. For last year’s badge, [charlie] put together a badge with an FPGA, SAM7 microcontroller, SD card, and OLED display. They were mining Bitcons on these badges.

The Hardware Hacking Village was loaded up with a dozen or so Metcal soldering irons, binocular microscopes, and enough solder, wick, and flux to allow everyone to solder their badge together. Everyone who attempted it actually completed their badge, and stories of badge hacking competitions at other cons were filled with tales of people sprinkling components on random solder pads. Imagine: a conference where people are technically adept. Amazing.

Pico-Kubik Quadruped Fits In The Palm Of Your Hand

December 3, 2014 by Bryan Cockfield 6 Comments

Most of the legged robots we see here are of the hexapod variety, and with good reason. Hexapods are very stable and can easily move even if one or more of the legs has been disabled. [Radomir] has taken this a step farther and has become somewhat of an expert on the more technically difficult quadruped robot, building smaller and smaller ones each time. He has been hard at work on his latest four-legged creation called the Pico-Kubik, and this one will fit in the palm of your hand.

The Pico-Kubik runs Micropython on a VoCore board, which allows for it to have a small software footprint to complement its small hardware footprint. It accomplishes the latter primarily through the use of HK-282A Ultra-Micro Servos, an Arduino Pro Mini, and a tiny lithium ion battery. It’s still a work in progress, but the robot can already crawl across the tabletop.

This isn’t [Radomir]’s first time at the tiny quadruped rodeo, either. He has already built the Nano-Kubik and the µKubik, all of which followed the first (aptly-named) Kubik quadruped. Based on the use of SI prefixes, we can only assume the next one will be the hella-Kubik!

Judge Spotlight: Sprite_TM

Sprite_TM

His friends call him [Jeroen], but everyone else on the Internet knows this god of hacks and mods as [Sprite_TM]. He’s done everything from hacking hard drive controllers to making the best computer ever made even better. As one of the preeminent hardware hackers around, we’re proud to have [Sprite] as a judge in The Hackaday Prize, and happy to interview him on his thoughts on connected devices, the cloud-based Internet of Things, and his process of opening up black box devices for some sometimes subtle modifications.

of projects keep you busy there?

I’m a software developer for a big broadcasting equipment manufacturer. Every now and then a hardware project comes along and I try to grab those too.
