Basically, you don't know what you're doing...
That's right.
and
you're asking us if this is OK. We'll need to see the
bill of materials etc. before making that judgement.
Use of a transistor normally requires a resistor somewhere.
I'll try to be clearer here :
From what I know about logical ICs, they understand 2 states : high (VCC)and low (GND). My idea of a logical circuit is that the ICs output the right
voltage (that's the sure part) and the right intensity to actually activate
the other ICs (that's the less sure part that may involve resistors). My
guess is that logical ICs are designed to output the right voltage and
current to activate efficiently any other logical IC along its path but I'd
like to be sure.
The transistor part brings no interrogation (maybe it should...).
If you want to take a look at the schematic, here it is :

The ICs are dual JK flip flops and a quad OR gates. The schematic shows JFET
transistors but I'll use more common NPN ones.
Thanks for your answers, even the sarcastic ones.
