I was recently involved in the creation of an instruction manual for a kit that will soon be released by Brodak. During the building of the prototype I shot over 250 photos for use in the instruction manual. Faced with the dilemma of needing to take photos of construction process that sometimes required two hands and not having someone handy to help I wrote a computer app. Using a digital camera on a tripod and a laptop running the app I was able to trigger the camera with a foot switch, crop and manipulate the image as needed then save the result ready for insertion into a Microsoft Word file.
Not sure how you guys that sell kits accomplish this but thought the package I put together might be of some use so I am offering the software for free to anyone that might be able to use it. The catch is I used what I had laying around and most of the hardware I used is several generations old. The good news is all of it is available on eBay for a steal if you are willing to do a little searching and maybe wait till it gets listed...
You will need the following...
Kodak DC3400 camera, This a 2MP point and shoot that I had the software developer kit for. It's an older camera but plenty good enough for this application. Can be had on eBay for $50.00 or less. You will need the USB cable and an AC adaptor if you don't like buying batteries. If the one you buy doesn't come with the cable or AC adaptor they can be bought off eBay. Just do a search for "Kodak DC3400".
Laptop running Windows 2000, the hardware drivers won't load in XP or later. If you don't have an older laptop laying around you can pick one up with Windows2000 already loaded on eBay for around a hundred bucks. It needs to have a Parallel Port for the foot switch and USB for the camera. USB-1 is fine as that is what the camera is.
Any foot switch that has a normally open contact can be used, again look on eBay. Do a search for "Foot Switch", if you can find a Linemaster it's one of the best. This is the foot switch Motorola used with it's public safety consoles. The foot switch will need to be connected to a DB-25 computer connector for the parallel port which is easy.
It is allot of trouble putting a system like this together but the first time you have both hands busy and need a photo you will think it was worth it. You hit the foot switch, after a few seconds the photo you just shot appears on the computer screen. At this point you can delete it and shoot another, adjust the brightness and contrast, crop as needed, convert to grey scale rotate etc. then save the new image. The crop function will automatically either give you a square image or maintain the aspect of the original.
Anyway, I haven't put together an installation package yet as I wasn't sure if anyone would even be interested. If this post generates enough interest I would be willing to take the extra step and upload it to one of my web sites so it can be downloaded. I expect the resulting file to be about 7 meg.
The following attachments are a screen shot of the app and a page from the manual I put together.. Let me know if this looks like something you might use..
