Polly on the lookout for the next target...
The 350D she is using is my old bust one (AF shot to hell), but is perfect for mounting manual focus lenses on!
I was on the street when I came across this officer directing traffic at a work site. He was professional and made the site safe and traffic flow smooth. Great guy too!
Day 196 (07.16.2012)
After a two week sabbatical while visiting her grandparents, Lola is back and ready for action! The neighborhood chipmunks and lizards should be on alert!
Happy Texture Tuesday!
(I used Kim Klassen's Walnut Ink and Dear Dreamer textures)
This was something crazy I noticed. I was waiting for a bride and groom to take their photos at a park before their reception, and I saw about a dozen rabbits like this guy just chilling in this garden area. They were all in separate areas, with bushes and other flower gardens between them. All of a sudden all of their ears stood up at the same time. They paid no attention to me when I first arrived but for some reason they all stood up in full alert a few minutes later. And I noticed a short while later that a dog was approaching nearby. But the amazing thing was they this particular rabbit couldn't even see the dog from his location, because a) he was facing the opposite direction, and b) there were large shrubs between him and the dog.
Anways, it was pretty cool to see this type of synchronized alertness they had and they responded and ran away.

Hi all,
Been working with Bob B to make an APRS Voice Alert radio from an inexpensive two way set.
The Kenwoods that can do this run about $1200 each.
If this project works, people can make one of these for about $200 bucks or less.
Right now I'm working on a 'red lined' drawing that seems to be good.
At this time,I have something that seems to meet all the requirements.
It's one of my inexpensive 40 watt, under dash Midland units with a bunch of 'mods' in it.
It supports the data channel of 144.39 and a number of Northern Virginia area repeaters and simplex channels.
I suppose I can stick in some NWS as well.
The #1 test radio is built into a 70-342B XL.
The 70-342BLXL is a 'wide space' radio, so the TX and RX will cover all of High band.
If you look up Bob WB4APR's web site you can learn more about the Voice Alert system.
It transmits APRS packets with a 100Hz tone.
The data packet with tone acts like an alert signal to someone with a similar radio.
The call sign and a short message (Need to get a photo of the TT3 Programing page with the particulars) will pop up on the Kenwood's text display saying that a Voice Alert station is near by.
This radio has no data display section, but the audio chain and the PL decoder are more or less stock. There is room in the design to the later addition of a 'ham hud' like device. At this time I lack the ability to afford one. Voltage and audio can be gotten from the radio, routed via pins on the power cable up to a remote display.
The radio receives 144.390 with a 100Hz pl as well, so if someone transmits a short voice message, you get to hear it, acknowledge and move on to a handy frequency like 146.52 . (Channel 52)
As it stands now, the radio has the APRS channel in it.
A modified TT3+ controller.
A fair amount of custom wire work.
When the radio is not on the APRS channel, the data transmission is inhibited.
(A couple of little gotchas.
We are mixing 25 year old comercial radios and more modern APRS controlers.
Some things are not going to fit all that well.
Any TT3 when first turned on, has a 'boot up' cycle.
Part of that is a transmit command. No way around it.
The TT3 boots up a touch slower than the radio.
So at cold start up, the radio wakes up on channel, just before the TT3.
If the radio is powered up on a voice channel, that data chirp is going to on the air.
No way around it.)
This is how I expect the unit to be used.
I expect it to be an APRS tracker first.
It will spend most of it's time on channel 00 (144.390 100hz tone encode and decode)
A voice alert station second.
If and when someone hears it, they can call back, then switch and answer to a working channel like 52.
General talk around third.
Some days we need to talk to each other, not just send data back and forth.
At the moment it has a few local channels in it, I can add more, for a total of about 30 voice channels.
What I would like is someone who drives a lot in the area to take it for a couple of weeks and see if it works as advertised.
My path to and from work most likely won't cut it.
What it will need.
A 2M Antenna.
A GPS puck (5 volt only, I have one but do not like to loan it out.
They are expensive.)
I can program your call sign into the TT3+ and add some of your favorite 2m channels into the program.

Former USCGC Alert, now in Vancouver, Wash. as a sea cadet training ship, under restoration. Launched in 1924.
Sometimes, no matter how careful you are at the feeders, some little Brownheaded Nuthatch butinski will show up and try to snatch the suet right from under your tail feathers!
This little Downy Woodpecker was determined to stand his ground and never budged. After a few seconds the Nuthatch gave up and took off to one of the other feeders.
346.366: One of the younger siberian/amur tiger cubs at the Milwaukee County Zoo stares across the exhibit at the African Lions, remaining on high alert. What you don't see here is the fact her ears perked up to where they're at compared to the previous frame and had a more serious face. I take it she wasn't amused.

many fun snowy action shots this week, but ultimately this one is a keeper. She's looking through a fence.
