I'm the kinda guy who designs circuits when I have nothing to do.
So recently I designed an ABX switch box using discrete logic.
Here's my Conceptual Schematic:
It seems to work fine in my simple Java circuit simulator, but I'm not sure if this will really work.
So is there anyone with electronic experience who can give me some feedback?
(anything wrong, improvements?)
Relays aren't drawn here because this simulator doesn't have the reed relays I'll be using.
The "ABX Switch" has a center-off position.
The "Randomize X Switch" is a Push-switch.
The "X" random is generated using a square wave and a human controlled "hold" switch.
Picture it like a wheel of fortune or slot machine if you will.
The "OR" gate in the center that's connected to its own input is used to hold the "X" status,
so that the status of "X" will be the same every time until the "Randomize switch" is pushed
I may switch the NOR gate for an OR gate and Discrete CMOS NOT Gate (Using 2 MOSFETs),
because Logic gates comes in packages of 4s.
Anyone know a small complementary MOSFET pair I could use?
(No surface mount packages)
