New 2-transistor 4-state circuit

A project log for One Transistor FlipFlop

Flip-Flop design with just one transistor. Nice for transistor-CPU's ! The principle can also be used for vacuum tube flipflops.

Hi hackers ! In the spirit of this One transistor flipflop, I now have a 4-state circuit with only 2 transistors and LED's to show the state. No clock signal needed this time ! You find it here:
