NC State, Centennial Campus Engineering Building One, Room 1007, 911 Partners Way, Raleigh, NC 27606 (same as IEEE/robotics/TAR meetings through May) Monday, Jan 13, 7-9PM. A map for finding the meeting and additional details here: https://triembed.org/meetings/at-ncsu/

Agenda:

Announcements 

Problem of the Month: Paul MacDougal

Presentation: Charles Lord, an area embedded development professional and expert instructor, will go over RTOS fundamentals as well as providing heuristics and guidelines to help answer the question of how much "real time behavior" you need. (Charles will be giving a presentation in February too: stay tuned for details)

Show and Tell and general discussion: Including examples of two new OSH Park PCB service offerings to be passed around for close inspection: do it yourself, pro quality flexible PCBs and clear solder mask over ENIG traces on a black substrate (so cool you should bring your shades to look at it!) Also, you can see their latest improvement over the old "mouse bite" tab routing that is being delivered more and more often. 

Door prize giveaways: Protocol highly variable!
 
(Prospective donations for the giveaway box always welcome!)

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.

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.
