Hackaday Links: July 23, 2017

Posted on by

Hey, you know what’s happening right now? We’re wrapping up the third round of The Hackaday Prize. This challenge, Wheels, Wings, and Walkers, is dedicated to things that move. If it’s a robot, it qualifies, if it’s a plane, it qualifies, if it passes butter, it qualifies. There’s only a short time for you to get your entry in. Do it now. Superliminal advertising.

Speaking of the Hackaday Prize, this project would be a front-runner if only [Peter] would enter it in the competition. It’s one thing to have a cult; I have a cult and a petition to …read more

Hackaday Prize Entry: Minimalist HTTP

Posted on by

For his Hackaday Prize entry, [Yann] is building something that isn’t hardware, but it’s still fascinating. He’s come up with a minimalist HTTP compliant server written in C. It’s small, it’s portable, and in some cases, it will be a bunch better solution than throwing a full Linux stack into a single sensor.

This micro HTTP server has two core modules, each with a specific purpose. The file server does exactly what it says on the tin, but the HTTaP is a bit more interesting. HTTaP is a protocol first published in 2014 that is designed to be a simpler …read more

DEF CON Badgelife: The ESP Rules All

Posted on by

Badgelife is the celebration of independent hardware creators, working for months at a time to bring custom electronic badges to conferences around the world. This year at DEF CON, Badgelife is huge. It’s not just because this year was supposed to feature a non-electronic badge, and it’s not because the official badge imploded last month — Badgelife is all about people spending most of the year designing, and manufacturing hardware, culminating in one very special weekend.

[Garrett] owns Hacker Warehouse, a store providing all kinds of neat hacker tools ranging from software-defined radios to lock pick sets to side channel …read more

Hackaday Prize Entry: BeagleLogic

Posted on by

A few years ago, [Kumar] created the BeagleLogic, a 14-channel, 100 MSPS logic analyzer for the BeagleBone as an entry for the Hackaday Prize. This is a fantastic tool that takes advantage of the PRUs in the BeagleBone to give anyone with a BeagleBone a very capable logic analyzer for not much cash.

This year, [Kumar] is back at it again. He’s improving the BeagleLogic with a BeagleBone on a chip. This is the BeagleLogic Standalone, a 16-channel logic analyzer at 100 MSPS using a single chip.

Like the BeagleLogic from a few years ago, [Kumar] is relying on those …read more

Friday Hack Chat: Making Electronics for Education

Posted on by

For this week’s Hack Chat on Hackaday.io, we’ll be talking with AnnMarie Thomas about making electronics for education. There’s a huge intersection between electronics and education, and whether you’re designing robots for a FIRST team or designing a geometry curriculum around 3D-printed objects, there’s a lot electronics can teach students.

AnnMarie Thomas is an associate professor at the School of Engineering and the Opus College of Business at the University of St. Thomas. She’s the founder of the Playful Learning Lab, and along with her students she’s created Squishy Circuits. AnnMarie is the author of Making Makers: Kids, Tools, and …read more

DEF CON Badgelife: Someone Finally Did It

Posted on by

Badgelife is the celebration of electronic conference badges, a way of life that involves spending far too much time handling the logistics of electronics manufacturing, and an awesome hashtag on Twitter. Badgelife isn’t a new thing; it’s been around for a few years, but every summer we see a massive uptick in the lead up to Def Con.

For the last few years, the designers and engineers deep into Badgelife have had the same conversation dozens of times. One person says, “you know, someone should build a badge that’s a quadcopter.” Another person replies, “Can you imagine how annoying that …read more

[Carl Bass] has joined the board at Formlabs. This is interesting, and further proof that Print The Legend is now absurdly out of date and should not be used as evidence of anything in the world of 3D printing.

Here’s something cool: a breadboardable dev board for the Parallax Propeller.

Finally, after years of hard work, there’s a change.org petition to stop me. I must congratulate [Peter] for the wonderful graphic for this petition.

Want some flexible circuits? OSHPark is testing something out. If you have an idea for a circuit that would look good on Kapton instead of FR4, …read more

Slimline Nixie Clocks

Posted on by

Everyone needs to build a Nixie clock at some point. It’s a fantastic learning opportunity; not only do you get to play around with high voltages and tooobs, but there’s also the joy of sourcing obsolete components and figuring out the mechanical side of electronic design as well. [wouterdevinck] recently took up the challenge of building a Nixie clock. Instead of building a clock with a huge base, garish RGB LEDs, and other unnecessary accouterments, [wouter] is building a minimalist clock. It’s slimline, and a work of art.

The circuit for this Nixie clock is more or less what you …read more
