Boston Linux & UNIX was originally founded in 1994 as part of The Boston Computer Society. We meet on the third Wednesday of each month at the Massachusetts Institute of Technology, in Building E51.

Hardware Hacking: Atomic Clock Building

Date and Time

Location

MIT Building E-51, Room 325

Summary

Federico builds an atomic clock out of a pocket-sized Sheevaplug device

Abstract

The emergence of many low-cost, off-the shelf boards supporting embedded Linux (or BSD) opens a wealth of possibilities for the hacker willing to expand her horizons to the possibilities of hardware tinkering. Using the lowest amount of custom hardware and pouring Perl and Shell Script over everything as the glue binding it all, we create a minimalistic device delivering a perfectly tuned network time source: your very own stratum-1 ntp server, turning a pocket-sized Sheevaplug device into your personal atomic clock. The sample designs provide an entertaining introduction to the skills needed to design basic embedded systems, and their unavoidable BIOS and operating system underpinnings.

Bio

Federico Lucifredi is the maintainer of the man suite, the primary documentation-delivery tool under Linux, a graduate of Boston College and Harvard University, and the Ubuntu Advantage Product Manager at Canonical. As a software engineer-turned-manager at the Novell corporation, Federico was part of the SUSE Linux team for five years, overseeing the update stack of a 150 million dollar maintenance business. Previously, Federico has been a CIO and a network software architect at technology and embedded Linux startups, and he has spent two years teaching in Boston University's graduate and undergraduate programs, while simultaneously consulting for MIT. He is a frequent speaker at user group and conference events, notably the Linux Foundation's LinuxCon, LinuxWorld, the O'Reilly Open Source Convention, and the IMPlanet conferences, where he was a panelist representing the Jabber community. Federico is a recognized expert in computing performance issues, and consults pro-bono with Standard and Poor's clients interested in Free/Open Source Software technical and strategic issues. He participated in the GPL v3 drafting process in the large-corporation panel.
