John Baker giving one of his famous BSD presentations.
|
The audience is riveted. :)
|
Some old and new faces.
|
|
Completely over the network using bootp (on a Sparc platform of course). :)
|
Here's the step by step process that Tweeks jotted down as John went along.
|
Charles Strang and his "Chrismas Light Controller" project from our Jan 2009 presentation (details here).
|
The up close from his light controller board side of the system.
|
Fredrik showing one of his first balance-bots.
|
This is a shot from the Solar Fest that XCSSA folks attended in downtown SA.
|
The ironic thing is the sheer amount of AC cabling the booths were using. heh..
|
Fredrik's way cool C64 datasette/SD-RAM interface project (from 2009-03-16 meeting).
|
It basically takes "tape files" and stores them to SD card.
|
VERY cool propeller ucontroller+LCD project... but we calculate would take 73 years to fill a 1GiB card. ;)
|
The SD-RAM slot he hacked in.
|
Fredrik's from Europe.. where the datasette was more common than the over priced C=1541 floppy drive.
|
Charles Strang debuting the T-Mobile/G1/HTC-Dream running the Google Android (Linux) OS. (also from the 2009-03-16 meeting).
|
VIDEO: This the way cool debut of Fredrik's vex-radio controlled cooler from our 2009-08-17 meeting).
|
The project is built into an old DVD case and particle board.
|
Very nice motor-wheel assemblies! ($220 a pair)
|
Yes.. that's solid aluminum bases, rims and pneumatic rubber tires!
|
VIDEO: Fredrik's RC-robot cooler utilizes some pretty sweet components! Around $300 total.
|
Fredrik showing off the undercarriage. :)
|
The guts are basic and clean. Yes the motor controllers are fan cooled. :)
|
And of course, Fredrik's favorite uC, the propeller. :)
|
John Baker admiring the engineering work.
|
XCSSA also loves to void warranties! This is a laptop who's CPU heatsink Tweeks hand lapped to a mirror finish for more efficient cooling.
