New boards
2002-04-09 by sasami@hotkey.net.au
I've had the new boards delivered, but life has had me out every day since!
I have completed and tested the much requested Gated Comparator, and are
very happy with it. This Gated Comparator is a much improved version of the
old one on the web site. Now all outputs are in the range 0V to approx 12V.
Instead of using a flipflop as the gated element, I have used an 8 stage
shift register. That means there are 8 shifted gate outputs available, as
well as the raw comparator output. Each of the outputs has a LED, making
adjsting the unit so much easier. Also, there is a secondary voltage control
input so the comparator break/reference point can be varied.
On top of all this, there is a D/A converted connected to the outputs of the
shift register, with the last 4 bits able to be switched in or out. This
gives some great little melodys or sequences. They will depend largely on
what is fed into the shift register, though due to the configuration will
always have a certain flavor. There is an inverted output for this as well.
Makes great 70s sci-fi computer sounds!
I will be getting the info up as soon as I get the chance.
Also, the analogic and a new voltage controllable digital noise/random pulse
train boards are in, but not checked as of yet.
More super psychos are in, so reserve yours early, before I announce them to
the world. The only board I am out of at the moment is the Chime.
Cheers,
Ken
