Scope

This group is focussing on Ideas related to Counters and Oscillators.

Modules

We try to divide all the Ideas related to our scope in some 5 or 6 Modules. Our Goal on the one hand is to define the modules in a way that allows one to design, implement and test the individual modules independently. On the other hand, we also want to ensure that it is possible to connect them to build bigger components with more functionality.

cell division

oscillator

triggering by hand

interface

diviser / counter

4 genes counter

All substances which are involved should be produced and decomposed quickly
S = concentration signal from the interface
R1 is produced by gene (1) and represses gene (0) and (3)
R2 is produced by gene (2) and represses gene (0) and (1)
R3 is produced by gene (3) and represses gene (1) and (2)
R0 is produced by gene (0) and represses gene (2) and (3)

toggle switch

reporter

This will probably be one or more colors to indicate the current state of the counter.
