First, did you know that RCA made a vacuum tube that was usable as a phonograph pickup?
Second, Feena Electronics. They introduced an interesting DJ MIDI controller in 2006. Since then, nothing. The last post to their forum was September 21.
Finally, this guy is building a duplicate of the old Metasonix Hellfire Modulator. He’s making a chassis for it out of plain sheet metal, and he apparently mated two toaster ovens together in order to bake powder-coating onto it. DIY FTW!!!
It’s an analogue drone-box with a much vaster range of sound effects than single-box devices can usually do. Simple yet complex.
(It’s strange that this Italian company has no contact info on their site except email.)
First, the “Acid Machine”, which generates pitches with a rotating wheel and LDR.
Plus, the Synth-Fan, doing similar business with a small computer fan.
And this, whatever it is.
