@pieter, my box is laser cut as well. Unlike most boxes, it only has one acryllic weld, making it much cheaper.
Unlike iorodeo, it will not be sold as kit. Everything will come flat packed, and you will use a screwdriver/fingers to attach the peices. For the same level of assembly and functionality, the iorodeo kit is 345, which is more than twice the cost of the setup I want to make. Unassembled, it is 285, but you will need a soldering iron and probably some jigs to glue it.
For the illuminator, I am not sure of the size or type yet. There is a good chance it will be an led light source, but I can tell you more about that this week as more parts arrive. (I have leds, they are ok).
@troland, I may consider a banana to my system adaptor if this takes off, but right now the boxes are only going to be compatible with this system, so you will need both. The reason is that properly insulated banana cables are about $10 a pair, and male plugs are upwards of $3. That makes it very hard to keep price in check. I do want to include "banana out" on the psu, in case you have a different gel box you like.
@john g, good idea, I will see what I can do.
You can read more about the design goals and comparisons to other systems at my blog, tequals0.wordpress.com . the current top two posts are about the box.

I am putting the odds in favor of integration, because that will keep costs low and keep the $150 price point within reach. The breakdown for individual components will hopefully be something like this for the integrated system:

Once the design is finalized, mechanical drawings and schematics will be available for all parts and will probably be licensed CC BY SA or something similar. I am using this as a litmus test to see if people are interested in other cheap lab equipment. I hope to drop the barrier to entry into biotech, and you can help by supporting this project. A lot of people say that, but check out the price comparisons- I let my design, and price speak for itself.
