Friday Hack Chat: Fashion! (Turn To The Left)

An underappreciated facet of the maker movement is wearable technology. For this week’s Hack Chat, we’re going to be talking all about wearable and fashion tech. This includes motors, lighting, biofeedback, and one significantly overlooked aspect of wearables, washability.

For this week’s Hack Chat, we’re sitting down with Kathryn Blair and Shannon Hoover to talk about the workability and washability of fashion tech. Over the last decade or so, wearable tech has become ever more popular, and these advances in the science aren’t just limited to amazing outfits lined with hundreds of Neopixels. Now, we’re dealing with biofeedback, clothing that …read more

Friday Hack Chat: Assembling In Quantity With MacroFab

Building one of something is easy. You see it here every day, and yes, building a single robot, or a board to convert Segas to HDMI, or an Internet of Things thing is easy. Manufacturing is another story entirely. You’re going to have BOMs to work with, you’ll have suppliers, and you need to deal with assembly, programming, and packaging. Do you even know where you’re going to store all those boxes of parts? Manufacturing is a difficult task, but luckily there are assembly houses and contract manufacturers ready to ease the burden a little.

For this week’s Hack Chat, …read more

Friday Hack Chat: The State of KiCad

KiCad is twenty-five years old — like most PCB design software — and right now it’s the best Open Source tool to lay out your circuits, plop down a few resistors, and create a PCB from scratch. Over the last few years, a lot of people have been turning to KiCad to design some very impressive boards, something no doubt related to the fact that KiCad is free in both the beer and speech senses.

Join us this Friday for Hack Chat, we’re talking all about KiCad. If you have grievances or praise to heave onto the developers, this is …read more

Friday Hack Chat: Eagle One Year Later

Way back in June of 2016, Autodesk acquired Cadsoft, and with it EagleCAD, the popular PCB design software. There were plans for some features that should have been in Eagle two decades ago, and right now Autodesk is rolling out an impressive list of features that include UX improvements, integration with MCAD and Fusion360, and push and shove routing.

Six months into the new age of Eagle, Autodesk announced they would be changing their licensing models to a subscription service. Where you could pay less than $100 once and hold onto version 6.0 forever, now you’re required to pay $15 …read more

Friday Hack Chat: Contributing To Open Source Development

Open Source is how the world runs. Somewhere, deep inside the box of thinking sand you’re sitting at right now, there’s code you can look at, modify, compile, and run for yourself. At every point along the path between your router and the horrific WordPress server that’s sending you this webpage, there are open source bits transmitting bytes. The world as we know it wouldn’t exist without Open Source software.

That said, how does someone contribute to Open Source? Maintainers do like to build their own little kingdoms, so how does anyone break into developing Open Source hardware and software? …read more

Friday Hack Chat: Reverse Engineering the Digital Compact Cassette

For this week’s Hack Chat, we’re talking about reverse engineering the Digital Compact Cassette. Why should we care about an obsolete format that was only on the market for four years?  Because if a copy of the Spin Doctor’s Pocket Full of Kryptonite costs $50 USD on the used market, it has to be good.

In the early 1990s, several different digital magnetic tape formats came onto the scene. The MiniDisc was magneto-optical, yes, but back in the day it was amazing for recording bootlegs. DAT also appeared in the early 90s, and it was a godsend for recording studios. …read more

Friday Hack Chat: High Speed Data Acquisition

For this week’s Hack Chat, we’re going to be talking all about High-Speed Data Acquisition. If you’ve ever needed to shove voltages, currents, logic signals, temperature, pressure, or sound into a computer, you’ve used a DAQ. If you’ve ever needed to acquire a signal at a very high speed, you’ve probably paid a lot of money for that piece of equipment.

Our guest for this week’s Hack Chat will be [Kumar Abhishek], engineering student, Hackaday Prize finalist, and creator of the very, very cool Beaglelogic, a logic analyzer for the BeagleBone. The interesting bit about the Beaglelogic is its utilization …read more

Friday Hack Chat: Fundamentals Of RF

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

Friday Hack Chat: DMX512 Gon’ Give It To Ya

DMX512 is the standard for theatrical lighting, and it’s best described as, ‘MIDI for lights’. It’s been around since the 80s, and in the decades since it’s been used, abused, and shoved into just about everything imaginable.

For this week’s Hack Chat, we’re talking all about DMX512. What is DMX512? How does it work? What can you control with DMX512? What Open Source projects use it? There’s a wealth of information out there, and a lot of very cool tricks you can pull with this ubiquitous lighting protocol.

Our guest for this week’s Hack Chat is [Martin Searancke], owner of …read more

Friday Hack Chat: Energy Harvesting

Think about an Internet-connected device that never needs charging, never plugs into an outlet, and will never run out of power. With just a small solar cell, an Internet of Thing module can run for decades. This is the promise of energy harvesting, and it opens the doors to a lot of interesting questions.

Joining us for this week’s Hack Chat will be [John Tillema], CTO and co-founder of TWTG. They’re working on removing batteries completely from the IoT equation. They have a small device that operates on just 200 lux — the same amount of light that can be …read more
