The Hakko FR-300 is a wonderful tool, but it does a very poor job of bending the unsoldered tab of a through hole potentiometer. While bending the tab forward the thought was clearly in mind “this is dangerous”. The tool slipped and while it was on the way to finger said finger was being withdrawn from the scene at warp speed, but not fast enough. You can even tell what size hole the tip fits.
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.

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.
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.
Starting with this month’s meeting and at each one in the future there will be a drawing in which lucky attendees can choose items from a collection such as those shown below.
Folks are invited to donate interesting items they no longer need to add to the collection for future drawings.
Next Wednesday and Thursday (each day self-contained) October 10 and 11, there will be a Design to Part (D2P) trade show. Free admission with registration at the door. 9:30am to 3pm each day. Raleigh Convention Center, 500 South Salisbury St, Raleigh, NC 27601. Details here on the Internet .
Thanks to Dan Stipe for the tip about this upcoming event.
A whole bunch of generous folks kicked in for the triembed.org domain renewal this year and we won’t have to deal with this for a long, long time. THANK YOU!
