Kumar Abhishek, creator of the BeagleLogic Standalone, will be hosting a Hackaday HackChat on Friday, November 17th:
This Hack Chat is at 9:30a PST, Friday, November 17th.
This chat is about data acquisition. Data acquisition (DAQ) is a process by which a signal such as voltage, current, temperature, pressure, or sound is measured with a processing system. A processing system can be an entire computer or a standalone chip. The goal of a good DAQ system is to provide accuracy as quickly and be as cost effective as possible.
Kumar [Abhishek] is an engineering graduate from the Indian Institute of Technology (IIT) Kharagpur, India, whose journey into the world of hardware began when he picked up the soldering iron at the age of 7. As a student under the Google Summer of Code (GSoC) program under BeagleBoard.org, [Abhishek] worked with BeagleBoard.org to realize a logic analyzer using the Programmable Real-Time units on the BeagleBone, called BeagleLogic. He has also served as a Summer of Code mentor for BeagleBoard.org.
In this chat, we’ll be discussing:
- The PRUs on the BeagleBone series of hardware, and their capabilities
- How BeagleLogic uses the PRUs to perform data acquisition
- Ways to program the PRUs
- (Ways of) processing the data acquired from the PRUs
This Friday: Jason Kridner of the BeagleBoard.org Foundation will joining Hackaday’s weekly Hack Chat to talk BeagleBone, PocketBeagle, the BeagleBoard.org community and more!
Topics for this Hack Chat will include the direction BeagleBoard is going, the communities involved with BeagleBoard, and how to get the most out of those precious programmable real-time units. As always, we’re taking questions from the community, submit them here.
As an extra special bonus, this week we’re giving away some hardware. Digi-Key has offered up a few PocketBeagle boards. If you have an idea for a project, put it on the discussion sheet and we’ll pick the coolest project and send someone a PocketBeagle.

My Omega2 Onion shield, using a AMS1117 for 3.3V and CH340G for USB to serial. Kind of ugly soldering here as I didn’t have a tip for the syringe to dispense solder paste, so I just smeared it all over and hoped it reflowed well. It kind of did, but I had a solder blob short on pin 14 +15 on the CH340G, so I just lifted those two legs off the board. I was so eager to get this board tested that I forgot to check that I had these 2mm pin headers. I had just enough to get this thing tested. Time to order more 🙂

Simple breakout board using the dirt cheap IC’s CH340G ($0.30/each on ebay) for Serial and a AMS1117-3.3 ($0.025/each) for power. Breaks out all pins from 2mm to 2.54mm headers. Plugs nicely into two small breadboards for prototyping.
