Attached is the original SMD drive circuit, as seen in Graham's video.
Circuit designed by Mike Nunnerley.
Mark that is a modulated drive circuit for another application

All depends on the level of control needed, for super caps you need a constant voltage constant current control, or your caps will be damaged (over charge and heat up). There are voltage considerations depending on the number of cells, it can work with as low a voltage as 2.6v but impractible with one cell with Fe=1.2v so 2 cells would be 2.4v+ some external input to make up to!!!!!
The basics are all in the pdf, but for each persons design there needs to be thought put into, the number of cells, the amount of H2, the external voltage source and current capability.
If you applied 2.6v across the Ni hydroxide electrode and the SS electrode for 60sec, you will get 60sec of H2 and a 60sec charge on the Ni electrode which will have taken the O2 and turned into Ni oxyhydroxide, an oxidation level higher. When you then connect that Ni electrode via a load to a zinc (metal) electrode, you will have 1.6v at a current depending on the load and will run for 60sec until discharged
The hydrogen produced in the first place was produced at around 96% efficiency, then after the oxygen produced more power via the zinc counter electrode. This is not OU, but it is in the SMD system the cheapest electrolysis of water for hydrogen "only" production, the hydrogen is the fuel in the end, or is it not!!!
You basicly get back 30% of your input power on each cycle.
