Does the science section have a power supply for electrochemistry

#1

…that allows you to manipulate volts and amps with knobs?

you might try the electronics department or the jewelry department too depending on what you have in mind exactly supplies for electroplating/annodization could likely be borrowed or cobbled together from jewelry or the electronics lab equipment and then the solutions for each could at least be handled in the science lab. further depending on what you want to do i teach a chainmaille class and i would eventually like to learn about and then teach electroplating and annodization. also on an only loosely related note in the next month or three ill be teaching a CLASS on copper patina.

Do NOT go grab a power supply from Electronics without permission from that Committee.

Some of their equipment is quite expensive and unique.

AND electroplating is not what their power supplies were designed to do. Different power supplies for different projects.

good point i did not intend to imply anyone should just be going in and grabbing anything i just saw this while doing something else and wanted to help out with a few starting places to look. however, its a relatively simple device and if the makerspace doesnt have it it seems like something someone could make for us or themselves if they were sufficiently motivated

sounds like hes looking for something a bit more controlable than a battery though which makes me thing color annodization in which case this might not be much help

Electroplating is a science. Not being snobby.

Depends what metal is being plated onto what substrate what type power supply should be used. Low amperage and high voltage or high amperage and low voltage (gold uses this variant)

Chrome plating leaves a very toxic bath to be cleaned up. Not good for DMS.

Some power supplies are fixed ratings others are not. And on and on.

The variations have mostly been figured out. Very interesting reading, if a bit dry.

Reminder to everyone about plating and etching: If you do electroplating or etching, the solutions you bring in, you must take home and dispose of properly.

They can not be dumped down any of the drains or dumpster at DMS.

“Neutralizing” them does not cure the problem of the metals in the solution.

What you can do at home is not the same as what you can do at DMS.

Someone needs to study up on what type plating you want to do along w/ sizes and other variables.
Figure out max voltage and max current for your range of projects.
With that info you can spec your pwr sply.
