Hallo German friends. I'm from Finland and would like to show you the selfmade iontophoresis system for hands I built.
I hope you don't mind me writing in English, you would not understand my german
This is the only thread about this issue I found on Internet but if you have links to other similar I would appreciate it.
I tested it last night for the first time and I think it worked like it should. I will continue using it for now on and can tell you how it works after one or two weeks.
I think I can't upload picture here but if you want to see it you can email me.
Before reading further remember that this is low voltage system and is not connected to the mains 230V. This is why my system is 100% safe against electric shock!
Here is short description about the system and components.
I used battery packs from my RC hobby. 16 cells total (9nicd and 7 nimh) which gives about 19-21,5V. I don't know for sure but I'll try to use second meter to read the voltage too.
I had a multimeter connected in series for measuring the current. It was not very accurate but the current was about 0.01A (~10mA). The feeling was right at the edge of unconfortable but I was able to keep my hands in there full 30min without too much trouble. To get accurate reading I'll get new multimeter on Tuesday. They only cost about 10-30 euros.
I searched pictures from google to illustrate what components were used. I hope it makes things clear. You can ask and I'll hapily answer.
The steel electrodes were made from bookends. I removed the paint with acetone and sandpaper from both sides.
I found some bowls that was perfect fit for the steel plates.
The multimeter was used for measuring the current.
I had non slip pads between the steel plates and my hands
Wires were connected to the plates with these.
You can use normal batteries for power. Remember that they are 1.5V when nicd and nimh are about 1.25-1.35V (I measured that). You'll need about 12-13 normal AA batteries to get 20V.
You need 2 or 3 battery holders.
Of course you need also wire and it should be good silicone wire and about 2m long each + and -.
This is very simple to make if you know something about electronics and can do solder joints (not necessary).
This system can be built for less than 50 euros! I was bidding on a idromed 4 at ebay and I'm glad I did not get it It was over 300 euros!
Ask, I'll answer happily. And I hope you can send me email thru this page. I'll change my settings if you can't. I might need english instuctions for that...
Thanks.
