Dear Justin,
Hey thank you for getting back to me so quickly. Yes I built 2 4 cubes, and can honestly say I will not ever do that again. I appreciate the information you gave. The lm 567 looks to be an interesting chip. I wonder if I will have to get 20 of them, and tune them to the desired frequency using resistors and caps. Still a few unknown properties, guess it is play with chips time. Keep me posted and again thank you. I will let you know what I come up with as well. Hoping for a very exciting effect!
Sincerely
