April 8th Meeting: Hitchhikers Guide to LoRaWAN! by Charles Lord

LoRaWAN™ – a Low Power Wide Area Network (LPWAN) specification intended for wireless battery-operated Things in a regional, national or global network. Join us as Charles Lord reviews the elements of LoRa and LoRaWAN, the advantages (and disadvantages) of this protocol, and the tools we need to develop IoT solutions that use LoRa – including building your own LoRaWAN hub. Charles will do a demo and show some examples of ways to build your own LoRa network for fun or commercial use. We will also look at how we can build our own LoRaWAN gateway using an inexpensive kit for both development and for deployment where a local LoRa provider doesn’t exist – and how to interface where we do have providers – like in the Triangle!

Charles J. Lord, PE is an embedded systems consultant and trainer with over 40 years’ experience in system design and development in medical, military, and industrial applications. For the last twelve years, he has specialized in the integration of communication protocols into clients’ products, including USB, Ethernet, and low-power wireless including ZigBee, 6LoWPAN, LoRa, and Thread.

February 11th Meeting: Microbe-powered Remote Sensing

 

The presentation slides are now in the meeting archive here.

Many different kinds of microbial metabolic processes  generate free electrons that can be harvested, either to enhance activities like water treatment or hydrogen production or to be a source of electrical energy.

Join us at the next TriEmbed meeting to find out how simple-to-make microbial fuel cells can be used to power embedded systems for truly remote sensor applications.

As well as seeing the presentation, you’ll be invited to join in a brainstorming session to invent and explore different solutions to a practical problem involved with a specific project.  There will also be a raffle for IOT and other gadgets and gizmos and embedded development supplies from the giveaway box.  The last part of the meeting will be devoted to show and tell and general discussion.

Meeting details are here.

NCSU and area CE/tech-interested students: This is for you!

In a recent edition of the Embedded FM podcast, you can listen to ideas for projects from a fire hose. This is a concentrated and amplified version of the sort of ideas regularly floated, discussed, and demonstrated every second Monday night in one of the NCSU engineering buildings during monthly Triangle Embedded Interest Group (TriEmbed) meetings.

If you’re a student hoping to find a killer internship or permanent job doing embedded development this summer, check out TriEmbed. Details are under the Meetings dropdown menu above.

We look forward to seeing and getting to know you there.
