Live Streams and Hack Chat From The Hackaday Superconference

Posted on by

Want to experience the Hackaday Superconference from the comfort of your own workshop? Just follow us on YouTube or on Facebook as two days of live streaming talks begin this Saturday morning.

This weekend is the Hackaday Superconference, the greatest hardware conference on Earth. While the Superconference is the most amazing gatherings of engineers and engineering enthusiasts, we realize that not everyone can make it out to our ultimate hardware conference. This year, we’re doing something special for everyone who can’t make it out — we’re opening up live streams and live chat to those who can’t attend. This is …read more

Which Microcontroller Is Best Microcontroller?

Posted on by

Let’s say you’re working on a project, and you need a microcontroller. Which chip do you reach for? Probably the one you’re most familiar with, or at least the one whose programmer is hiding away in a corner of your desk. Choosing a microcontroller is a matter of convenience, but it doesn’t have to be this way. There are dozens of different ARM cores alone, hundreds of 8051 clones, and weirder stuff including the Cypress PSoC and TI’s MSP430. Which one is best? Which microcontroller that costs under a dollar is best? That’s the question [Jay Carlson] tried to answer, …read more

Hackaday Prize Entry: A Mess Of VGA On A Breadboard

Posted on by

Before all our video games came over the Intertubes, before they were on CDs, and before they were on cartridges, video games were all discrete logic. Pong was the first and you can build that out of several dozen logic chips. The great [Woz] famously built Breakout out of 44 simple chips.

For [Marcel]’s entry to the Hackaday Prize, he’s taking the single board microprocessor-less computer to the next level. He’s building a multi-Megahertz 64-color computer on a breadboard. What’s the capacitance of a breadboard? Just ask [Marcel].

The design of this disintegrated computer has just about everything you could …read more

Hackaday Links: Remember, Remember

Posted on by

Buckle up, buttercup because this is the last weekly Hackaday Links post you’re getting for two weeks. Why? We have a thing next weekend. The Hackaday Superconference is November 11th and 12th (and also the 10th, because there’s a pre-game party), and it’s going to be the best hardware con you’ve ever seen. Don’t have a ticket? Too bad! But we’ll have something for our Internet denizens too.

So, you’re not going to the Hackaday Supercon but you’d like to hang out with like-minded people? GOOD NEWS! Barnes & Noble is having their third annual Mini Maker Faire on November …read more

Mergers and Acquisitions: Broadcom, Qualcomm, and One Hundred Billion Dollars

Posted on by

Rumors have been circulating this last weekend of the largest semiconductor acquisition ever. Broadcom might buy Qualcomm for the princely sum of one hundred Billion dollars.

You will most likely be familiar with both Qualcomm and Broadcom for their wireless and cellphone chipsets. As far as the Maker community is concerned, Broadcom makes the chipset for the Raspberry Pi, but in the context of a two hundred Billion dollar company, a ‘maker’ focused Linux dev board is the equivalent of a rounding error on a balance sheet.

This news comes a little more than a year after the announcement that …read more

Friday Hack Chat: Fundamentals Of RF

Posted on by

Designing a system for communication over RF is a dark art. It’s an obscure domain filled with photonmancy, wires going every which way, and imaginary numbers. RF is reserved entirely for wizards. The guy who simplified Maxwell’s equations into the form we now use went literally insane and replaced all the furniture in his house with granite blocks. This is weird stuff, man.

For this week’s Hack Chat, we’re talking about RF. Everything from the capabilities of different bands, how bandwidth is incorporated into designs, different modulation schemes, RF concepts, I/Q, Nyquist, and other deep-dive topics that elucidate the mysteries …read more

How To Build An Airplane In A Month And A Half

Posted on by

For the last few weeks, RC pilot extraordinaire [Peter Sripol] has been working on his biggest project to date. It’s effectively a manned RC plane, now legally a Part 103 ultralight. Now all that work is finally bearing fruit. [Peter] is flying this plane on some short hops down a grass runway. He’s flying it, and proving that you can build a plane in a basement, in under two months, constructed almost entirely out of insulation foam.

[Peter] has been documenting this build on his YouTube channel, and although the materials for this plane are mostly sourced from either Home …read more

Hackaday Links: 👻 🎃 Spooky Edition, 2017

Posted on by

A few links posts ago, we wrote something about a company selling huge LED panels on eBay, ten panels for $50. Those panels are gone now, but a few lucky hackers got their hands on some cool hardware. Now there’s a project to reverse engineer these Barco NX-4 LED panels. Who’s going to be the first to figure out how to drive these things? Doesn’t matter — it’s a group project and we’re all made richer by the contributions of others.

Prague is getting a new hackerspace.

A year and a half ago, a $79 3D printer popped up on …read more

Analyzing The 6502 With Python And Cheap Dev Boards

Posted on by

The Before Times were full of fancy logic analyzers. Connect the leads on these analyzers to a system, find that super special ROM cartridge, and you could look at the bus of a computer system in real time. We’ve come a long way since then. Now we have fast, cheap bits of hardware that can look at multiple inputs simultaneously, and there are Open Source solutions for displaying and interpreting the ones and zeros on a data bus. [hoglet] has built a very clever 6502 protocol decoder using Sigrok and a cheap 16-channel logic analyzer.

This protocol decoder is capable …read more
