Canon t2i, adapter ring, Bauch & Lomb objective

Friday, April 2nd, 2010

This is a Canon t2i HDSLR, with a EF-S adapter, connected to a 10x objective from a Bausch & Lomb binocular microscope. This also works mounted to the microscope, and will drastically improve the shooting I’ve attempted with the Nikon 4300 which I’ve done freehand.

It may also work for 18MP stills, but I am not sure if there will be enough light.

The results of shooting 720p HD @60fps have been promising, will need to load a better profile to shoot 1080p.

I have no idea what this is.

But it does a little scissor-step sort of dance at the end. I’m trying to use my Nikon4300 to record what I am seeing through the new microscope. It is a bit of a hassel, since I don’t want to spend money on a proper mount. Will look in to PVC.

Its a microbe.

It's a microbe.

Here is also a video, I apologize for the quality. Working on that.

Another Ice Season Ends…

Monday, March 5th, 2007

The end came quickly for our ice-covered body last week. One rainstorm later and we’re back to raucous waves and starting a healthy Spring Turnover.

Speaking of which, the underwater ice probe/camera/etc tests have come to a halt for the year, or at least until perhaps December. I will post the footage here when I get some time to compress what I’ve taken so far.

One step closer to 24/7 access to our lakeside biome. Interfaces between different environments always make for the most interesting observations - they are where most of life’s activity takes place, where there is most advantage to be gained. Where water, land and air meet is chock full of diversity!

Piece of Discovery’s external tank at ET separation, or ?

Saturday, December 9th, 2006

Not sure what this was that came off Discovery’s external tank during external tank separation, and the strut seems to block the view. Sorry for the moire pattern, I am pulling this off screen to save time, may get a better d/l from the source later -this was fastest.

Here is the clip

Things that go beep in the night.

It’s starting to get cold. Time to start DXing again!The cool night air reduces moisture. This helps with optical astronomy as well.What is DXing? Simply put, DXing is the reception of distant transmissions. It comes from the radio broadcast abbreviations for transmit, tx and receive, rx. For me, it is about receiving space-based transmissions from manned and unmanned vehicles, in Low Earth Orbit (LEO) or beyond.

Is There Anybody Out There?
DXing is a relatively inexpensive hobby, that I find fascinating. An antenna of the right configuration and a radio scanner is all you need to get started. Below I have added links to a bunch of resources related to DX, including the Amateur Deep Space Network - a great group that is very informative.
I joined last year, and have learned a great deal, even just sitting and listening. To the group I mean.

Middleware (more like middlewhere?)

Middleware, Middlewhy, Middlehow
This is the presentation that I use for the talk on the purpose of Middleware and also use to pitch the Maya/Lingo middleware community. Note that I don’t talk my bullets, so it is lean on text. You can view the material here.
