Sci Fi Siren Sound Tests

First tests of the Sci Fi Siren outlined in the previous post. The signal from the unit is a little hot so i've soldered a 68K resistor to the jack outlet from the negative to the ground to reduce it a little. I think I may up this to 200K if I take this unit out. I'm pretty pleased with the results. The LDR makes the unit quite unique, the low end bass wobbles are quite usable as well as the high squelchy sounds.
