How would I make a Zener diode current source? Something like this? From Wikipedia

I don't know how to figure out what resistors/transistors/diodes I need.

I guess what I'm asking is, how do I calculate what resistors I need, and the rating for the transistor and the diode (I don't know how to tell if the circuit will burn them out).

Edit: I want the load to receive 1 Amp, the resistance of the load is 0.97232Ω, and I am supplying the circuit with either 8.4V, or 9.6V probably 9.6V.

What I'm looking for, is a set of equations to find values for the resistors. I(believe) I can assume that nothing in the circuit will experience current more than my target current of 1Amp? If that's true, I can get parts rated 1.5-2 times my target current.

Schematic of the circuit I want.
