Diffuser PJ Mapping Screen Built!

It is so easy to underestimate how quickly time flies! You may remember two weeks ago I posted about having chopped all the wood and I just needed to get glue, well yesterday I finally got it, and was up until three this morning getting as much as I could done. I ran out of No More Nails about 3/4 of the way through, so I got up first thing this morning and went to get another tube.

Below is a photo gallery of the build from start to finish for your amusement. I have to say, considering the issues I had with the original cuts (breaking a circular saw and having to hand cut half the posts, I am really happy with the results, it looks really beautiful. All that remains now is to let the glue set hard and then get it sprayed matt white, as this will give the best surface finish for the Projections.

1) So as I have touched on before, QRDude is the software I used to create the design for my diffuser. This is a 2D QRD design, with a Scatter characteristic of 333hz, a diffusion characteristic of 666hz and a high frequency cutoff at 3750hz.

2) Here we have all the posts for my build stacked on a secondary baseplate. I intend to build another three of these after university, so I have bought extra MDF for baseplates. The wood used for the posts is Planed treated Red Wood Pine,  44mm x 44mm. The "well" depths vary from 0mm upto 24mm.

3) Here is another baseplate cut and ready to be filled.The well spread is 13, giving the baseplate a width and length of 572mm

4) I decided to go from the two axis first and then build out from there. This isn't really standard practice, you would normally just go row by row, however as I said the circular saw broke, so from 14mm posts down, the hand cut is slightly uneven on a lot of posts. To eliminate the chance of an uneven design, this way lets you glue two sides of every post you place after the axis are done, resulting in a more stable build as you go along.

5) Here you see it at just after the half way point, around one thirty this morning. I knew by this point that I had made the right choice as the lines and block placements were still going smoothly and perfectly.

6) This was just a couple of arty angles before I went to bed.

7) The first of these three was a quick one before I started again today with the fresh No More Nails. This will be painted white as I said, and then placed behind the speakers, central to my mix position. Happy Days!
