I have searched the forums and the internet but could not find an answer.
I want to make a TENs machine that I can control (http://en.wikipedia.org/wiki/Transcutaneous_electrical_nerve_stimulation
I have an old tens machine that I have taken apart but I have not been able to find any circuits or manuals for it on the internet. It is a Boots model 2BT on the case but this seems to be a white labelled device. The circuit board names it as "Ultima tens (m) 7". Here is a link to another rebranded one but it looks exactly the same: https://www.tenscare.co.uk/index.php?action=products&product=108
I have found this circuit for a TENs machine:http://tinypic.com/view.php?pic=wlsm0n&s=1
My question is - would I be able to repurpose the existing machine that I have so that I can control it?
