Nerf Guns !!

Some of the Nerf Guns Alex got for Christmas.  He needs his uncle for the larger Blaster . 

The Mega-darts are cool .  They whistle... 

Pic of the Day

Very simple Arduino code just to check out the board ... 

You can see how easy it is to use the digital I/O and the serial port . 

Pic of the Day

Today's pic of the day is the Arduino Due I grafted on to the old Radio Shack Sensor Lab. 


It doesn't look like much , but it should get my feet wet and help convince me to get an Arduino Esplora .

Messing around with Python this evening

... On the Raspberry Pi

... Using the examples in the Raspberry Pi Education Manual.

Like I mentioned on FB , it's been a while since I wrote programs for fun .

Friday Fun

After dropping my son off at school, I had breakfast with the gang from the Broken Arrow Amateur Radio Club at the Kenosha Cafe. 

Guy had my day planned and sent me off to Ray's to work on his DVAP and Raspberry Pi.

The DVAP is a low-powered RF to Internet gateway for D-STAR traffic. 

It works.  Didn't take too long to make up a Raspberry Pi SD Card, get the Pi booted and set up with the DVAPTool program and then we were chatting to folks on the 030C reflector with his Icom ID-51 walkie talkie and the DVAP.

More to follow on this interesting aspect of ham radio.  At this point, in a nutshell, suffice it to say, the audio is good (digital) there is a low-rate data sub channel and almost all D-STAR repeaters pipe their audio to the Internet.  This makes it easy to make up "conference calls" of several users and repeaters.

Scratch Programming

Off to a couple baby steps with Scratch Programming.

Long story short, you drag and drop blocks into programs. There are blocks for moving little guys around the screen, printing, drawing, control structures and the rest.

You set up a free account, and your code is stored out there on the Internet, so you can mess around with Scratch from whatever computer is handy. Looks to be an off-line editor as well.

 If you get a good program, you can save it for later use. And share it with others.
Get started at scratch.mit.edu

There are some YouTube videos to get you started as well. http://www.youtube.com/results?search_query=Scratch+programming&sm=12

Raspberry Pi Computer

Something that we have sitting out in the garage is a Raspberry Pi. It's hooked up to the Kantronics KPC-3 TNC through a USB hub and a USB to Serial Adapter. The KPC-3 is connected to the Yaesu FT-817. Makes for a neat packet radio station. Since it's getting cold(er) in the garage, I have the TightVNCServer running on the Pi. That's letting me remote in from an old laptop inside the house where it's warm. More on the Raspberry Pi and Packet Radio later. Scott

Geeky Thursday !

What's on tap for tonight ? I'd like to look into the Scratch programming language and see how hard it is to make simple graphics, maybe something that will capture my son's attention. We will see when I get home. Until then, Scott

Hello World. More to follow. Scott
