New band lineup baby announcement

My wife Ester and I are expecting and since we’re both musicians we grabbed our guitars and did a fun photoshoot to announce our good news. Inspired by this creative announcement we came across.

A Maker Wedding

Initially I wasn’t sure how much our wedding was truly going to represent my fiancée and I, after all, we wanted our family and friends to enjoy themselves and feel included — as with any large event there are a lot of expectations to manage. After deciding to craft my own Edison-style light fixtures for our reception I realized that the occasion was, in addition to a celebration of our life-long commitment to each other, an opportunity for us to showcase our creativity and perhaps introduce some of our family and friends to aspects of ourselves they may not have known existed.

In retrospect we probably took on too much, but it allowed us to feel the occasion was a true reflection of ourselves — for me this meant soldering, stripping, crimping, twisting, programming and no small amount of brow furrowing. None of these projects could’ve come together without the help of my wonderful wife Ester, who not only said yes, but also collaborated throughout and trusted me to deliver on some very important aspects of our big day. In addition, a big thanks to my dear old Dad who took time to help me with the lengthy task of wiring the Edison fixtures and to the friends and family who helped us setup and teardown these, and other installations.

Converting the Canon TC-80N3 for use with the Rebel XT (and others)

After having fun with some infrared and macro photography I wanted to try some time lapse. Some cameras have built in intervalometers ( big word for interval timers ) which allow you to do time lapse with little effort. Sadly the Canon Rebel XT does not, so I searched around for solutions, most of which are quite expensive.

I found out some useful information:

  • the Rebel XT has a 2.5mm stereo jack connection for remote operation
  • connecting the ring and base of this jack trigger the autofocus
  • connecting the tip and base of the jack triggers the shutter

With this information I hacked together a makeshift solution with a 12v relay, 12v wall adapter and an X10 appliance module. This system sucked and wasn’t portable, but it was all junk I had laying around. Anyhow, I went back to searching and found out about the TC-80N3, a Canon wired remote which does all sorts of fun timer stuff, including time lapse and goes for under $100 on eBay now and then. Unfortunately it doesn’t work with the Rebel XT, the connector is different, out of the box at least.

I found out that it has three leads on the connector, as the Rebel does, so perhaps they function the same? It seemed to be the case so I went and purchased one, hoping to just swap the connector out.

Once it arrived I went straight to hacking it up. Chopped off the old connector, found out that there are two wires and a ground wire, sweet. With the help of my multimeter I determined that the red wire is the shutter and the white wire is the focus. So, to attach the new connector:

  • solder the red wire to the tip of the 2.5mm jack
  • solder the white wire to the ring of the 2.5mm jack
  • solder the ground to the base of the 2.5mm jack

Slip the cover back on or tape up the connector, whatever, and it’s all done. The Canon TC-80N3 modified to connect to and control a Canon Rebel XT. Doesn’t need much know how at all to pull this off.

Macro Photography on the Cheap (ish)

Not long after I picked up my Canon Rebel XT 350D I realized the stock lense left a lot to be desired. After drooling over numerous macro photos on Flickr from this same camera I decided to look into a macro lense. Not being a pro photographer I couldn’t really justify spending $250+ on something like the Canon 50mm f/2.5 or better so, as I often do, I poked around for a comparable, less costly solution. That’s when I found out about Kenko Extension Tubes.

Kenko Tubes are lense extensions, they have no optics, they are connected between a lense and the camera, by changing the distance between the lense and the sensor it changes the focal length. This allows you to focus on objects which are much closer, hence, macro photography. These tubes come in sets allowing you a number of combinations.

So I purchased some Kenko Tubes ( http://www.the-digital-picture.com/Reviews/Kenko-Extension-Tube-Set-Review.aspx ) not knowing that they would not connect with Canon EF-S lenses, such as the EF-S 18-55 that came with my Rebel XT. Damnit!

Some searches revealed that you can modify the tubes to work, so here’s how it’s done. Basically, there are a number of plastic rings inside the Kenko Tubes whose diameter is not wide enough to allow the EF-S lense to insert the required depth to be able to lock the ridges.

You can simply take a dremel to the frist ring in order to widen it to accomadate the EF-S lense. All you have to do is be careful not to grind too close to the brass connector pins, only grind the first ring and remove all debris when you’re finished.

The red in the first pic is the opening which is too small, the green is what’s got to be removed. The finished pic shows the larger hole.

This,

Plus this,

Gets you this,

I did this on the 12mm tube figuring if I ruined it, I’d still have the others and if I wanted to use them I could simply attached the 12mm to them instead of grinding all three.

You can check out more of the resulting photos w/ the tubes on my Flickr.
