I said in an earlier post that I intended to use LED strips mounted below a perforated plate to give a scanning effect.
I used six strips wired in pairs, 1 - 4, 2 - 5 and 3 - 6, driven by a 3 channel chaser. Although it worked well, I found that where one's line of sight made direct contact with an LED through a hole in the plate, there was a considerable glare. It was therefore clear that I needed some sort of defuser. Fortunately, I had a large sheet of semi opaque plastic sheet in the workshop, so I cut out a piece and taped it to the underside of the plate. That solved the glare problem, but I then found that the scanning effect was largely lost and became more a sensation of flashing lights. So the next job was to build little 'compartments' for the strips, thus containing the light from each in a specific area. I assembled dividers between each strip but was careful to ensure they weren't quite high enough to reach the underside of the perforated plate, thus allowing a certain amount of light 'bleed' from one compartment to the next.
I am extremely pleased with the end result, even though it did take a while to get there.

I don't care what everybody else says about you JC, I think you're damn smart and no mistake! !THUMBS!

If someone had a tattoo like a bar-code would it tell them their best by date? !PUZZLED!
I think we'd like to see a video of it please and we demand it now!

A technical question, is Sharon still talking to you after she'd drilled all of those teeny holes?

Looks great! I thought you'd be using those Ahrens cast feet you were selling to put on your cabinet?

Yes, I can probably do that.......but then what do I do with it? The favoured method appears to be bung it on youtube and then embed a link here. But I don't have a youtube account and don't particularly want one. So if J or S or anyone else wants to volunteer to take receipt of some short clips and edit them into a nice little video, then let me know.

It was always my intention that the machine would be of a 1930s art-deco appearance, which I think I've achieved (you can all judge for yourselves when I eventually get around to taking some pictures). So I think the cast feet would have looked out of place...........anyway, they're sold now.

And all I have to do is remember how to take videos with the camera. !PUZZLED!

Anyway, I've finally downloaded from the camera some pictures I took back in April - and they were all rubbish! However, this is quite a nice one of the top pediment (guess what colour the machine is). The machine has been on site down at Brighton for the last month - I'll try to get some pictures tomorrow....... and just hope they're better than the last lot.

Forgot to mention, the machine is sited in the Sealife Centre, Brighton. I went in yesterday to take some pictures - took three and the batteries ran out (I really don't have much luck with cameras). Additionally, the light is pretty poor where the machines are situated, so they're not particularly good pictures anyway. I'll try to get some better pictures next week.
