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: 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

An Even Smaller BeagleBone

The BeagleBone famously fits in an Altoids tin. Even though we now have BeagleBone Blacks, Blues, and Greens, the form factor for this curiously strong Linux board has remained unchanged, and able to fit inside a project box available at every cash register on the planet. There is another Altoids tin, though. The Altoid mini tin is just over 60×40 mm, and much too small to fit a normal size BeagleBone. [Michael Welling] has designed a new BeagleBone to fit this miniature project box. He’s calling it the Pocketbone, and it’s as small as the mints are strong.

The Pocketbone …read more

Reverse Engineering the Smart ForTwo CAN Bus

The CAN bus has become a defacto standard in modern cars. Just about everything electronic in a car these days talks over this bus, which makes it fertile ground for aspiring hackers. [Daniel Velazquez] is striking out in this area, attempting to decode the messages on the CAN bus of his Smart ForTwo.

[Daniel] has had some pitfalls – first attempts with a Beaglebone Black were somewhat successful in reading messages, but led to strange activity of the car and indicators. This is par for the course in any hack that wires into an existing system – there’s a high …read more

Hackaday Links: February 19, 2017

The ESP-32 is the Next Big Chip. This tiny microcontroller with WiFi and Bluetooth is the brains of the GameBoy on your keychain, emulates an NES, and does Arduino. There are ESP32 modules that are somewhat easy to acquire, but so far the bare chips have been unobtanium. Now you can buy them. One supplier has them for $3.60 USD/piece. That’s a lot of computational power, WiFi, and Bluetooth for not much money. What are you going to build?

What is the power of artisanal product videos? The argument for this trend cites [Claude C. Hopkins] and how he told …read more

Hackaday Links: The 2017 One

You screwed everything up last night. The end of 2016 had a leap second, so instead of the seconds going up from 57, 58, 59… 00, there was a 61st second in the last minute of the year. Yeah, 2016 just wouldn’t quit. [Michel] built a device to keep track of 2016’s leap second using GPS, and everything worked beautifully.

Remember MechWarrior? There’s a reason those mid-90s games used mechs instead of more organic characters. Computers couldn’t draw that many polygons, making MechWarrior a stylistic choice driven by the limitations of technology. Here’s a real MechWarrior that could rip your …read more
