For lectures and presentations the device can also include a laser pointer that will gently fade in and out to alert the user.

The PCB being constructed in these videos is an open source Zigbee module. Zigbee is a low power wireless mesh networking technology based on IEEE 802.15.4 initially aimed at home and industrial automation. You can get the PCB from

Hopefully I'll post some new pages for my other hardware and software projects soon. I might even resurrect the old brokentoaster software site from the 90s.
