A t2i / 550D Magic Lantern firmware Alpha is Now Available!

Trammel Hudson of Magic Lantern fame has started porting the custom Magic Lantern firmware to the cannon t2i / 550D. So for it seems to be an alpha release,  but I suspect that things will start moving more quickly now. In this first release the only new features appear to be audio monitoring and lens info, but that is a great start. In my opinion the poor audio quality of the t2i is in my opinion the biggest flaw the camera has right now. With manual audio control and a little skill, I think the t2i could be used to shoot feature...

Canon T2i/550D Practical Video Review

I got my hands on the Canon T2i and I ran it though it’s paces, the things I was most interested in was the video modes and low-light performance. To see the HD version downsized to 720p, you have to load the video from vimeo directly: Canon T2i, 550D Practical Video Tests. T2i Vs. 7D First a quick word about the T2i vs. the 7D. The T2i does not have that pro-feel that the higher level cameras have. The body is fairly light and it is most defiantly made of plastic, and you can tell when you hold it. For me...

The “Cheap and Easy” Photo Backdrop

Every now and then everyone needs to take a photo of something small, there’s an easy (and cheap!) way to get a great looking photo with a white background. As soon as you see the technique, it’s hard to forget, it’s a plain white poster board propped up against a wall or whatever you have handy. Fill your camera’s view with the poster board and take the photo. For lighting you’ll need a reflected flash or some bright lights, but that is not the focus of this article. I’ll soon do an article on my...

Warning Label Generator

So today a friend of mind sent me this image, I’m not sure where it came from exactly, but I knew I need one for my laser room. After doing a quick search for examples to make mine, I came across this Warning Label Generator site, it’s not new, but is useful. You can choose the sign type and an icon, and enter your own text. A custom graphic might be better, but this is quick and easy. That is all.

Abandoned House

A few weeks ago I had the opportunity to take a bunch of photos in a turn of the century abandoned farm house, and it was very cool. It was out in the middle of nowhere, Minnesota.    The house was in disrepair and was pretty treacherous, but not seriously dangerous. Some walls were smashed, garbage strewn around, and there were trees that had not been trimmed back in years. But no graffiti or fire damage.   Check out the full galley here: Abandoned House Also, if you’ve been missing the lack of cool new...

Photos: Running a exposed hard drive, and then ruining it

Way back in 2002, I ran an experiment with a hard drive to see how durable the inside actually is, mostly curious to see how easy it is to ruin a drive. In the 2nd above photo you can see the drive arm moving, all of these photos were taken while the drive was being used in a live system.    We removed the cover of a old IDE hard drive and proceeded to format and install windows. We didn’t make any attempt to protect the drive, and the office we worked in...

John Aho’s 3rd PSCombine Set

It’s been a while since I’ve posted anything PSCombine related, if you are not familiar here is a short blurb: PSCombine is a program that will import your collection of images or photos and randomly combine them in Photoshop with a random blending, opacity, and filters. I like to think of it as "Computer Assisted Art". It’s free to use, all you need is photoshop, go check out the PSCombine project page for more detail. If you have a PSCombine gallery let me know, I would love to see it. John...

Pi Pie

This isn’t incredibly unique, but while searching for photos on another post I wanted to share it with the world. It’s a pie, with the number of pi around the edge, plus the pi symbol is carved in the lid. Also, apple pie is awesome. I want some now.

Modifying Micro Servos for Continuous Rotation

There are many ways to power your next project but I’m quite partial to the continuous rotation servo because it’s very easy to hook up to your micro controller, you don’t need to build or buy a separate controller or h-bridge to power the motor. In a servo all that is built in. All you need to do is connect the power directly to your battery and send a low-voltage control signal to tell it what you want it to do. Servos out of the box are meant to rotate in a fixed range of 180 degrees, but modifying them for...

Jansen Walker: The story so far

Update Note: While I'm keeping this post for historical value, this post is not kept up to date with my Jansen Walker, look at the Jansen Walker project page for the latest details and plans. Original Post: If you’ve been following my posts lately I’ve been putting a bunch of my time into a robotics project that uses the Jansen mechanism for movement, if your not familiar look below for an animation. I've spent quite a bit of time on the mechanical design on this robot, maybe more then was strictly necessary since I used this opportunity to learn SolidWorks, and since...

Image: Pet Godzilla

Shutter Speed: 1/200 sec Aperture: F/6.3 ISO: 1600 Focal length: 35mm Here in Portland on some of the old streets you’ll find metal rings embedded in the curbs that were originally installed in the early 1900’s and were made to tie your horse to. Eventually people started ironically attaching toy horses to the rings, and just the other day I found this dinosaur / Godzilla attached to a ring. Very clever. On another note, I’ve decided to discontinue my image-a-day posts, I’ll still be posting pictures from time...
