To power the analog computer Confetti one needs a positive (+12V) and a negative (-12V) voltage and in between the common ground (COM). With the Mean Well 15W DKE15A-12 or the Mean Well 15W DKE15A-15 power module one can build an quite powerful power source. Both 12V and 15V is possible and works fine with the Confetti.

An other possibility would be to build out of two 9V batteries the +9V and -9V Battery Supply.
