Simple TENS voltage booster


I have a simple question. For a hobby project I am building a simple TENS muscle stimulator. To keep the electronics simple I want to use a simple boost switching converter. the PWM to power the inductor I will provide with an Arduino. Besides that circuit needs a simple switch to turn it on and off, to create a pulsating effect. This is also been done in the Arduino with a digital pin.

So i really need only the booster circuit to create a high voltage for the muscles to contract.

I have a simple schematic for this type of 'booster circuit', but I dont have the knowledge to find out which exact parts i need. I put the schematic in the attachment. I know it is the most basic booster circuit there is, it can be a little bit more complex than this :)

I also want to make the unit with 8 channels so i have to make the schematic 8 times. I don't care if i need 8 small batteries, but the channels should all be controlled via the ardiono pin switch i mentioned before.


-only a simple voltage booster schematic with part list.

-i dont need PCB design

-arduino PWM to high voltage

-fast switch to turn voltage on/off with arduino digital pin

-possible to make more channels

-3v battery

-safe for human use!!

I think this is a simple job for you that you can complete in 2 hours or so? Maybe I am wrong. Please tell me how long it will take for you.
