Need an electrolysis setup

The_Great_Orgo - 1-3-2019 at 13:23

I have a project that I'm looking at starting but don't know where to begin.

I need a 2-12v power source and some kind of electrolysis box. I watched Nurdrage's video on his electrolysis box but some of the parts have stopped selling on ebay and don't know too much about the equipment required. I'm here looking for recommendations for equipment, preferably cheap but effective.

Woelen, one of the mod/admins here, has a website with lots of interesting things, here's one that was useful to me:

It is a tutorial on making a power supply using a pc power supply (which you can probably find cheap or free).

In what current range do you plan to work? In the range up to 10A it is more productive to start out with a standard SMPS of around 12V DC and couple that with a downconverter module (or even better a SEPIC converter module) that can be regulated from Vin down to 1V or smt like that. A SEPIC module can up and downconvert, so you have a wider range of voltages available from a single SMPS (e.g 1-50V DC out from 12V DC input).
You can throw in some panel amp and voltmeters to make a decent universal lab power supply. All of the components are available from ebay or other sources for some bucks.

E.g:

Mash it all together and something of the following variety of contraptions shall emerge:
