Alternative short distance rangefinder: measures light transit time, not reflection angle

Here’s a device available on a pair of Sparkfun boards that Rod pointed us and Triangle Amateur Robotics to:

Teaching Microcontroller Programming to Middle Schoolers Inexpensively

February 9th TriEmbed Meeting at NCSU

 This month’s meeting will have a highly focused theme: Tools and techniques for teaching middle school age children without spending a wad on hardware. There will be two speakers:
  • Alan Smith will bring examples of the boards related to his  Wizarding 101 and 102 classes for middle schoolers and will focus on what he’s  learned teaching introduction to microcontrollers from these classes as well as a full course.
  • Jon Wolfe of Anibit will talk about a graphical programmer he’s been developing.

More details, directions, etc on the “Meetings at NCSU” page.

Meeting at NCSU/Engineering building THREE this Monday

This Monday the 12th at 7pm there will be the first meeting of the new year. We’re returning to a totally casual format this time, but if you have something worth sharing via video recording please send a note to the mailing list. Bring your physical and virtual show and tell items and any announcements, comments or questions that feel right.

For January and February the meetings will be in EBIII on the opposite side of the engineering campus from the parking and past meeting locations. Be sure to look at the meeting details page here to orient yourself. There will be signs on some of the doors of the other buildings but the local teleportation devices are down for software upgrades, so expect a good hike in any event.

 

December 8 Meeting Presentations Available

Craig Cook recorded the most recent TriEmbed meeting’s presentations about C Preprocessing with the Arduino IDE, custom tools for laser-cut acrylic enclosures, getting results from the T962/T962A reflow ovens, and a tool being developed to allow easy bicycle wheel truing.

After being crunched through Handbrake they’ve been put on Youtube. Details of these and past meeting archives are on the TriEmbed Meetings/Archives page.

 

(By the way: smart phones don’t appear to render the menu bar of the TriEmbed web site’s main page, turning the whole thing into a set of three parallel lines near the upper right corner of the page. Clicking on that drops the nested menus for meeting, email, project info, etc, that is more obviously available with a desktop browser).

At least one Radio Shack is upgrading itself with “Fix It Here!”

FixItHere

The Radioshack at Cary/Crossroads has set up a cellphone and tablet repair station in the corner of their store. It’s called “Fix It Here!”.  My eyes nearly popped out at the site of state of the art SMT rework tools right there, with a very sharp guy named Matt who knows how to use them. He’s there and ready to fix your broken glass, failed connectors, etc. The phone number is 919 851 0332.

And this particular Radioshack now has a wall full of Little Bits as well as a scrupulously maintained inventory of the other gadgets and gizmos embedded hobby enthusiasts need. I was encouraged that maybe they will adapt and pull out of their spiral.

(I have no connection to Radioshack, but I’ve been buying stuff mostly here since this store was opened. )
