A project log for TENS Circuit on breadboard

I build a TENS curcuit following an online description on a prototype board.

After a bit of clicking around on Google I came across this website: TENS Circuits

I decided to go for revision 4. The schematic can be found on that website. i am not going to post it here seperatly.

I figured that I want to use the circuit since it uses NE555 timers which I haven't used before.
