told me about three years ago, to place a granite slab ( from my new kitchen countertops) over some kind of isolation device. The slab was intended to be used as my amplifiers base. Since it weighted about 80lbs, it was difficult to have it laying down the floor and a floating device was needed.
I came with the idea of having (3) PVC reducers , 3" to 1.5" with a concave center hole, filled with (3) concave door knobs and (3) racket balls seated on top of the knobs. They were placed under the granite slab and the whole system floated like a Roller Bearings base , but with the addition of some Air Isolation.
The DIY project cost me under $12 ( $3.00/balls, $3.57/concave knobs and $3.00/PVC reducers).
I also try it without the knobs and just seating the racketballs over the PVC reducers. It was more stable and it depended more on the air pressure without the rocking movement from the concave knobs ( the beraings effet).
Why I mention this? Well, as I said, I like DIY projects, specially if simple and cheap. This Gingko devices looks interesting but I'm not able to invest $99/set....so I came with the idea of telling you guys about my devices. I heard from this Gingko about 2-3 months ago.
I'm not saying that my DIY mini clouds are like the real Mini Clouds , but it would be interesting to see if anyone of you guys can experiment with a home-made set and compare both.
