Jimmie Rodgers stopped in to Microcontroller Monday

Posted on by

Jimmie Rodgers (http://jimmieprodgers.com/) came by the space on Monday and gave us a demo of some of his cool Arduino projects, his kit business, and just generally hung out.

For those of you who don’t know, Jimmie is the man behind the Open Heart charlieplexed LED hearts and the LOL shield, which are pretty cool Arduino shields that he’s been selling through the Maker Shed. Either of these kits would make a neat learning-Arduino platform, IMO, and give you a fun finished project in the end.

It was great having him in the space! Thanks Jimmie!

XMPP Beyond Chat (Presentation by Arc Riley)

Posted on by

HacDC is developing an XMPP stack to coordinate networked messages to and from microcontrollers over WiFi, serial, and radio. It will ideally enable a near plug-and-play way for people to network their microcontroller projects and display them at HacDC. XMPP is “an open, XML-based protocol originally aimed at near-real-time, extensible instant messaging (IM) and presence information (e.g., buddy lists), but now expanded into the broader realm of message-oriented middleware.” It serves as the backbone of Google Talk, for example. One of the first projects to be linked to our framework will be an ambient lighting system for the space.

On Thursday, August 12 at 7:00PM, as a part of the NARG meeting, Arc Riley will present on the some of the XMPP aspects of this endeavor and will discuss PubSub, Data Forms, and Ad-Hoc Commands. Any individuals interested in these interesting aspects of XMPP beyond chat are encouraged to attend, and, like all HacDC activities, the event is free and open to the public.

At the end of the presentation, we may do some code sprinting and ensure that those attending have access to the distributed code repository.
