Frame Construction
Thursday some wood was purchased from the wood-a-torium (B&Q) as well as some fixings. The decision was made to use metal brackets to attach the feet to the frame rather than braces because it was easier and would look better.
The wood for the vertical supports were marked at suitable heights and four lengths were cut equally. The same was done for the feet.
The location of the screen was market and holes were drilled above and below it. This allows the perspex sheet to be pinned between the wooden layers and not have to directly drill it. Hopfeully this means there is more chance of getting reimbursement from the college as it can be re-used. Bolts were put through the holes and washers then nuts were place on the other side and tightened.
The metal ‘L’ brackets were screwed in at the bottom of each piece of wood with wood screws. The feet were left off for transportation but just need to be screwed into. The position of where the vertical supports would go has been marked to make things easier.
The perspex should arrive on Monday and they it will be time to test fit the whole setup. Tracing paper will be added as the projection and diffusion surface and a projector will need to be requisitioned from somewhere in order to test the tracking system. All that remains is the retro fitting of the webcam with an IR filter, Something that could be either very easy or very difficult; it appears to be leaning towards the latter.
The IR LED lamp that was purchase decided not to work when plugged in yesterday but after some quick correspondance with the seller it was discovered that a light sensor was on the back so it would only come on in the dark. A level of automation for IR CCTV cameras. This problem was quickly soved with some blu-tack.
