that has had some DIY plans for desks and racks along with full blown room modifications. I found some good links earlier ths year.
I am contemplating plans myself but I need something to be able to lock all my gear (monitors included) from the reach of my wifes cats and our two kids BUT be able to open it up, flip it on and be recording in just a few minutes as I have very limited time opportunities to record.
Also just to complicate things I would like to be able to move it fairly easily for possibly going portable in the future.
The final criterea for my needs (to keep my wife from having a cow) is it has to blend in with the bedroom furniture. Not Thomasville but not particle board, plywood or black laquer either all for under $100-$200.
I built a flip top hutch/scroll desk that was stained to match the bedroom furniture but I quickly outgrew it and it takes too long to get my monitors out of the closet. Plus my recorder and mixer are above my "rack" so theres is no way to get comfortable seated in front of the recorder and mixer... no leg space.
I am contemplating building two new rack towers with a "desk" that will span the two towers that can be secured and removed. The desk will have "rails" on either side that can support a "lid" to cover the desk. The desk has to have a place to keep the monitors out of reach when closed but will allow quick desk top monitor placement at ear level. I just have the Mackie 1402 VLZ-PRO and a 4-track cassette for now but hope to get a DAW (Yamaha AW16G) or computer based system so I don't need alot of space.
With the two seperate rack towers and removable desk top they could easily be loaded into the back of an SUV.
If I can pull all of these features together functionally and asthetically there could be a market for this...... hmmmm.
