dattaway's site of awesomeness

 
My hobby is pursuing the art of communications technology  and welcome to my cluttered desktop of what I find awesome. Communications is the great force that shapes our society and is the magnet of my essence.

The level of detail of this project exceeds known levels of awesomeness:

The rest of the site is the next level of ham radio, but don't just take my word for it.

Layout is everything.  This Beagleboard delivers.

Continuous ink for Canon MG5220

posted Dec 18, 2012, 11:44 AM by duane attaway   [ updated Dec 18, 2012, 1:42 PM ]

Self feeding, self resetting cartriges, for $50.


For ink, I use the Hobbicolors 5 color ink kits, which is good and cheap.  Note there are two kinds of black, a pigment and dye type.  Using non-pigment in the pigment print head doesn't work too well and clogs up quickly.

I use Linux and found the Sabayon distribution just works with this printer.  Other distributions were a major pain.  I like the development environment of Gentoo, so Sabayon will do.

Fixing USB problems with the Raspberry Pi

posted Jun 19, 2012, 5:08 PM by duane attaway

I was able to fix the USB problems on my Raspberry Pi.  My wireless wifi adapter kept failing, no hard drives worked, and the USB hub didn't work well either.  Each Raspberry Pi's USB port has a current limiting 140mA fuse, which isn't enough for most devices.  The main fuse is 700mA.  I was able to jumper these out and place a larger coupling capacitor across the USB power rails.  Everything works now!



The Raspberry Pi is small...

My camera was able to capture the detail of the chip on a chip on the Pi:



This would take some serious soldering skills.  I wanted to build one as a kit...

Motorcycle 32 Club and Bikers for Babies, Kansas City 2008

Why do we ride when its freezing every Sunday morning while most people are sleeping?

We meet Sunday mornings for breakfast

Done with breakfast

So we may enjoy a Sunday morning ride

To get out of the city and see the country

Almost there

This is what its all about

Taking breaks from riding in the morning, but some of us don't want to stop

Let's go already!

Great to be out in the middle of nowhere

While most people are still asleep, we are enjoying the fresh cool air

Taking a break

A good day

Ready for the next ride!

Bikers for Babies 2008

We gather before the ride
More show up!
And more show up...
We get a crowd going
We ready to ride yet?
NOW we are ready to ride!
Thousands of bikes
With no end in sight!
Enjoying a great lunch!
Some of us are ready to ride again!

The Old Geezers Ride

Because rain or shine, a day must be enjoyed
We escape on roads to nowhere
to be where we want to be
Its always a good day to ride
Every turn leads to new places
We won't know until we get there
somewhere far away
far away
and to take a break from it all
stretching
until we ride the day out and head back
Heading back to town

Fueling up
Let's go!
Engines ready
Ninja!
Waiting for everyone else...
Doing the pre-Ninja ride dance
We're ready!
Back on the road!
Riding is freedom!
Another stretch break and turning the bikes around
Spin around!
Not a straight road in sight
Bikes everywhere
Ready for another ride next week!

Canon sx210is test pictures

posted Jan 24, 2011, 5:45 AM by duane attaway   [ updated Jan 24, 2011, 6:11 PM ]

These pictures from the sx210is pocket sized camera were taken around midnight from the same location.  

First with no zoom using a 4 second exposure gives a daytime appearance, second at 14x zoom reveals a parking lot, third with 56x reveals a dealership, and the fourth enhanced to about 400x.  No tripod was used.  The last image should demonstrate the camera's image excellent stabilization abilities at night.  The optional free CHDK software in the camera may extend these abilities much further.


Macro picture of a 1" IBM Microdrive assembly. 

At the closest range of this lens, that one square inch device equals about 2500 pixels each direction, providing plenty of resolution to work with.  Color fringing from the super zoom lens may be seen in the extreme macro closeup.  The capacitors are about the size of salt grains.


Picture of an electron gun

Technical detail is shown of the three cathodes from a 19" color monitor illuminated by a white LED. These cathodes normally stream electrons charged at 29KV, just below what we define as the xray spectrum.
