arduino wart remover?

This website sells a product that claims to get rid of warts using electric pulses. I want to build my own arduino version. :slight_smile: Wartabater information

According to the site, 21.27kHz of pulsed DC voltage is very effective against the virus.. Also some sites say it needs high voltage and low current to destroy the infected area..

I was thinking of using the back emf from energized coils for its high voltage and low current.. and have the arduino pulse it to the desired frequency.

I don't know if anyone has tried this here, but I'd like to hear your opinions/suggestions on how to go about it. :slight_smile:

The two guys who said that ulcers were caused by bacteria, h. pylori, and could be treated (cured) with antibiotics, were told by the medical establishment that they were crazy. But they got the Nobel Prize > 20 years later after one of them used himself as a test subject (getting an ulcer from having ingested the bacteria.)

The Trick is how much pulsed (rf) current is required and at what level do burns occur... They will burn the skin in a manner akin to heating (The method of killing the Virus is localized heating) If I remember right, I actually used to, at one time repair Medical Electronics equipment... in the late 60's diathermy, ultrasound heating and various myostimulator's were common Chiropractic 'Therapeutic" devices, I hated the Xray machines the most... a 100 KV cable exploding is NOT pleasant to be around...
But I digress, my issue is that without some kind of guidelines as to acceptable limits for therapeutic application you verge into very dangerous area's burns from equipment of that nature are deep in nature as the rf Yes 21 Khz... will penetrate the skin much deeper and take an accordingly longer time to heal and during that time are more susceptible to infection. What I am trying to say in so very many words is that idea might be more dangerous than it appears to be... IMO

Thanks for your replies guys! It looks like someone has already built it with 555 timers..

and

They use 9 volt batteries and a voltage tripler. I'd rather use Arduinos to be able to adjust the frequency more precisely.. :slight_smile:

This reminds me of a demonstration I saw once, at a talk given by a couple guys from the Tesla Museum. They had a small Tesla coil device which was used to administer current as a therapeutic treatment. I did a quick web search, hoping to find a specific example, and came up empty, but the web abounds with pages about electro-therapy, electromedicine, bioelectromagnetic healing, etc.

a simple NE555 with the correct components; Polyester caps and .1% mf resistors is capable of better frequency stability than the Arduino is... I was getting .05% accuracy in the mid 80's with that part easily and that is at least an order of magnitude better than needed... 1% is real easy. The other thought is why oh why is it necessary to use a $15.00 part when a $0.05 part does it as well??? are you intending to enter the field of patent medicine or do you have a wart you don't/can't show to a doctor?

Doc

lol no im just curious of what this technology can do, and how it can selectively destroy unwanted tissue by selecting the correct frequency.

heyarn:
can selectively destroy unwanted tissue

In that case you need to declare your location so we can be sure to put the tinfoil suits on if we ever drive past your lab :stuck_out_tongue:

21.27kHz of pulsed DC voltage is very effective

This certainly follows the basic rule that you have to supply lots of digits to demonstrate accuracy.
If it works at all, anything between 20 and 22 kHz will have the same effect, and perhaps 10 or 50 kHz is way better ?

So does anyone have code I could work with to pulse at 2.27 khz? :slight_smile: I figured to get to 2.27KHZ, the cycle should last 47 microsecs. so 23.51 micro secs turned on, and 23.51 turned off?

is it as simple as:

int outPin = 8;                 // digital pin 8

void setup()
{
  pinMode(outPin, OUTPUT);      // sets the digital pin as output
}

void loop()
{
  digitalWrite(outPin, HIGH);   // sets the pin on
  delayMicroseconds(23.51);        // pauses for 23.51 microseconds      
  digitalWrite(outPin, LOW);    // sets the pin off
  delayMicroseconds(23.51);        // pauses for 23.51 microseconds      
}

Yes: 47 µs cycle is 21.27 kHz
No:

  1. 23.51 is not an unsigned long
  2. a few µs to restart loop() and to jump into the delayMicroseconds() function and return

And there are other methods to setup timers and tie them to output pins.

Just adapt Nick Gammons hints on Timer interrupts http://www.gammon.com.au/forum/?id=11488
( valid for a 16MHz Arduino ):

ISR(TIMER1_COMPA_vect)
{
static boolean state = false;
  state = !state;  // toggle
  digitalWrite (13, state ? HIGH : LOW);
}
void setup() {
  pinMode (13, OUTPUT);
  
  // set up Timer 1
  TCCR1A = 0;          // normal operation
  TCCR1B = _BV(WGM12) | _BV(CS10);   // CTC, no pre-scaling
  OCR1A =  375;       // compare A register value (376 * clock speed)
  TIMSK1 = _BV (OCIE1A);             // interrupt on Compare A Match
}  // end of setup

void loop() { }

edit: added code tag myself :wink:

Hi, just a thought..
Some tima ago I researched a project called a "rife machine" which used an oscillator at the self resonant frequencies of bacteria
and viruses. There has been alot of work done on this, but you might find it interesting.

It's that way with "medical marijuana", too. :smiley:

The period 21kHz is 47usec: maybe brief positive-going pulses, maybe negative-going pulses, maybe they should be Gaussian - 1/2 on & 1/2 off.

Naaah, use 0 - 100% PWM and tune for max smoke...

Good thing you retired Doc- your professional indemnity insurance must have been costing you a fortune 8)
