Well the design worked pretty flawlessly. The frame bolted together quickly and easily and is just waiting on the OpenRail to arrive to finalise the frame. I will still need to undo a few sections to attach brackets and bearing blocks but...
So things have been slow coming, but I was given a rust free frame to transfer the project to. The current one is dangerously rusty on the frame rails... So that's the next part of the project... taking a LOT longer than expected...
Here's an update on the progress I've made building an enclosure for the device: The enclosure is made out of a couple oatmeal containers attached to a frame of foam board. The front is a piece of mat board (roughly the same thickness as the...
The Defocused Computer Perception (DCP) module is used to 1) detect motion on each floor and 2) determine if the motion is coming towards the HVPT or moving away.OpenCV2 is used with python bindings to make this work. First three images are read, thresholded...
Had a Sunday afternoon free, couldn't resist banging something together with whatever I could scrounge from the dustbin outside. Looks pretty cool!:Next, I'll make some proper slide rails, re-build the frame out of something better, add the LASER (a...
SO I had to leave most of the machine behind to save weight, but I kept the guts. In setting it up and playing with it, I wired something wrong on the laser driver circuit and let out some smoke. I was planning to update that part anyway, but this now...
LCD shutters are the best bet for the Peril-Sensitive Sunglasses.It's not cost-effective (and would be re-inventing the wheel) to re-create LCD shutter glasses so the base of the project will involve hacking an off-the-shelf pair.
The Sony 3D active shutter glasses for the PS3 have been chosen to follow up as one of the basic pieces of hardware. They look reasonably normal, and the price is right - only 9.99 at a local shop.Next stage of the project involves reverse-engineering...
The Sony PS3 3D Shutter Glasses are disassembled by removing 6 very small cross-headed screws, then pulling the glasses apart into separate halves.Two screws hold in the nosepiece.Two more are on each side, by the hinges. Fold the arms to expose...
The glasses have been disassembled and a basic means of triggering the LCD shutters has been determined.Each LCD lens has a small mylar ribbon connector going to the main PCB. There is one at each corner.For each connector, the inner contact (nearest...
This is a prototype and also development hardware, so it won't be size-optimized. Size-optimizing is usually the opposite of "easy and accessible to work on".The sensors will be separate from the glasses, allowing development to happen in a reasonable...
The tiny light sensor board gives some nice and stable analog readings based on amount of ambient light. It gives a "0" well ahead of full darkness however.Software-wise I treat it almost identical to temperature sensor - read values...
It's time to move the hardware off the breadboard and turn it into a functional prototype.Because we're making only the one to play with and there's no time to do things like a custom PCB, we're going to need to use a protoboard, have wires everywhere,...
