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

Friday Hack Chat: The Incredible BeagleBoard

Over the last year or so, the BeagleBoard community has seen some incredible pieces of hardware. The BeagleBone on a Chip — the Octavo OSD335x — is a complete computing system with DDR3, tons of GPIOs, Gigabit Ethernet, and those all-important PRUs stuffed into a single piece of epoxy studded with solder balls. This chip made it into tiny DIY PocketBones and now the official PocketBeagle is in stock in massive quantities at the usual electronic component distributors.

For this week’s Hack Chat, we’re talking about the BeagleBoard, BeagleBone, PocketBeagle, and PocketBone. [Jason Kridner], the co-founder of BeagleBoard and beagle …read more

Friday Hack Chat: Crypto Challenge

It’s the middle of August, and that means all the hackers are back from DEF CON, safe in their hoodies, with memories of smoke-filled casinos, interesting talks, and, most importantly, crypto challenges.

This year was an ‘off’ year for DEF CON. There was an official badge, but it wasn’t electronic (which no one expected), and there was no crypto challenge (which no one saw coming). Nevertheless, there was already a vibrant community of badge builders, and the crypto nerds of DEF CON were satisfied by PCB locks from the Crypto and Privacy village, Benders, and Darknet phone dials this year. …read more

Friday Hack Chat: PCB Manufacturing

There’s a world of difference between building one of something and building multiples of something. The effort that goes into manufacturing does not scale linearly, and manufacturing is a skill in itself. This Friday, we’re going to be talking all about PCB manufacturing and assembly over on Hackaday.io

On deck for this Hack Chat will be [Jonathan Hirschman], the brains behind PCB:NG, a turnkey electronics manufacturing startup based around NYC. Jonathan is a self-taught hardware guy, proficient in PCB layout, 3D CAD, and manufacturing tech. PCB:NG is, essentially, taking oldskool manufacturing and making it into more of a digital process. …read more

Friday Hack Chat: Electronics Design And Naming A Puppy

For one reason or another, Hackaday has an extended family of ridiculously capable contributors. One of the most illustrious is [Bil Herd], Commodore refugee, electronic engineer, medic, and all-around awesome guy. He’ll be joining us over on Hackaday.io this Friday for a Hack Chat on Electronics Design.

This Friday, we’re hosting a Hack Chat with [Bil]. If you want to talk Commodore, this is the guy. If you want to talk about PLAs and programmable digital logic, this is the guy. If you want to know how to build a system from scratch in just a few months, [Bil]’s your …read more

Friday Hack Chat: 8-Bit Micros With Microchip

A few years ago, Microchip acquired Atmel for $3.56 Billion. There are plenty of manufacturers of 8-bit microcontrollers, but everyone makes 8051s, and the MSP430 isn’t as popular as it should be. Microchip’s acquisition of Atmel created what is probably the largest manufacturer of 8-bit micros, with a portfolio ranging from ATtinys smaller than a grain of rice to gigantic PICs.

This Friday, we’re hosting a Hack Chat with the Technical Marketing Engineer of 8-bitters at Microchip. If you love AVR, this is the guy to talk to. If you’re still rocking the vintage 1993 PICkit, this is the guy …read more

Friday Hack Chat: Audio Systems

Join us this Friday for a Hack Chat on Audio Systems. It’s going down June 2 at noon PDT (handy time zone converter thing).

Every Friday, we gather round the campfire with the best in the business to tease out whatever secrets are stored in their mind. This is the Hack Chat, and this week, we’re going to be talking about audio systems with [Dafydd Roche]. Bring your low-distortion volume knobs and porcelain speaker cable risers, this is going to be a good one.

[Dafydd] got his start in electronics in an application for a music degree. He mentioned he’d …read more
