Thanks guys, I just wanted to have some input on the electronics part of my project. I am a biologist and I can take good care of the rest. I appreciate the input from everyone.
Sadly, normally it is not a good idea to share project plans or other scientific details online before actually...
I am that scientist anyway (without the electronics and chemistry parts), I hope you don´t know of someone already on this... that would be a bit problematic :D
Indeed it is, but I don´t see how this makes a difference. My plan was to definitely ask someone here locally. I personally think it is useful to get first my own ideas together (even asking around on a forum) and then further discuss with someone. I think it is helpful to put eventual...
Are you suggesting to buy the raw material (a steel sheet/plate), cut it, make electrodes out of it ? I don't know how easy is to find someone cutting a steel rod in thin "chips" but.... thanks, this is useful... I will consider it :)

Yes, exactly
both things would be...
Thanks Klaus for checking, I think In my first post and some few replies after I did.
I just paste them here so that is easier to find what would be eventually missing in the explanation :)

Hi all, first of all I am really no expert, so I apologize in case I make gross mistakes. I have...
Thanks SunnySkyguy for your comment. Just to be more precise: water is a solution containing ions and charged molecules. It is precisely for this reason that electrical signals can be transmitted through your neurons and it is for the same reason that some animals use electrical signals to...
Thanks Klaus. In theory it could be as fast as LED and the change should be a "translation" so that the pattern of activity would move origin, locked to an object moving above the array. I thought to use OpenCV to "feed" the coordinates of the "origin" to the board whenever a movement is...
Just a query for anyone that could advise me on this:
What would you suggest to easily interface a small PC to a laptop (via serial port or USB) in order to test materials and conductivity? At this point I would try to avoid any arduino like concept, if possible.
Thanks in advance!

@Brad: Actually no but the presence of metals should be very limited if not avoided. In the case of PCB obviously there is metal but is probably a thin layer so it could be OK. In the case of LEDs there is metal too but they are tiny... In addition the pattern should be re-arranged on demand so...
Thanks Klaus
I will make a search and check costs and feasibility based on what you suggested. LED would be used with infrared...the animals would probably not detect those. I do not know how to control the voltage but I thought perhaps via PC using some software interface connected to an...
Thanks Andre, you are right.
I do not need to record. I need the electrodes to produce a constant "detectable" potential that could be set or programmed via PC. The electrodes won´t record. They will just be emitters.
I would record them just in trial sessions while testing (one important issue...
Hi all, first of all I am really no expert, so I apologize in case I make gross mistakes. I have some ideas in mind for a project and I would like to get some inputs in order to see what's feasible or not and what's the best way to do it.
I would need to design an underwater electrode (no...
