A pulse device is often used in alternative medicine. Its primary goal is to boost the users immune system. It kills likely bacteria, viruses, fungi, toxins, etc. by applying very small currents through the body with a specific pulse and frequency. Dr. Hulda Clark promoted this method in the handbook for self-health and the various claims and counter claims about its effectiveness are all for what it's worth. This DIY circuit can be made for 12 dollar. A timer is build in, for a 8 minute session. The device affects and kills multiple types of parasites by using a frequency sweep depending on the position of the potmeter. It can be used with hand- or wrist electrodes.

Supplies

The electronic scheme shows all the parts
A circuit is build on a PCB single island board
2 copper tubes 10cm long, 1.2cm diameter
9 Volt alkaline battery with clip and leads
1 DIL-14 IC socket and 1 DIL-16 IC socket
A push button, connector and 50Kohm potmeter.
One circuit/battery housing

Step 1: Pulser Video

Step 2: The Circuit Operation

Activating the push button starts the circuit. By releasing the button the mosfet BS170 takes over the power line untill the 4040 disconnects the circuit after 8 minutes. The 4040 counter resets by start-up at pin 11. The counter clock is delivered by IC2a. 200 miliseconds (5Hz) is the time between 2 pulses. It makes (depending on the position of potmeter VR-1) a frequence sweep by the ramp generator build up around IC2a. The voltage controlled oscillator IC2b delivers a 1 microsecond pulse of 9Volt. The output current is limited to 9mA by the 1 Kohm resistor, that keeps operation shortcut save. The LED functions also as 'on' indicator for the device. The ground and the 1Kohm resistor are connected to the body by hand or wrist electrodes.

Step 3: Construction

The circuit is build-up on a printed circuit board. I usually make first a test setup on a breadboard. This project I build right away on a single island PCB. Use IC sockets and place the chips in when the whole circuit is ready. Do first a double check. Use a simple housing for the PCB and battery. Make a connector for the electrodes, so you can change them. The push button, potmeter, connector and LED are the only parts at the outside of the housing. The electrodes are simple copper tubes. Wrist electrodes can be made with copper foil and velcro. This keeps the hands free for doing other things. Some people connect a coil to the connector to place near an inflammation. Its worth doing experiments for what helps the best.

Step 4: Conclusion

This Instructable shows a low cost diy pulse device. With some soldering experience people can make this pulser but it can only be checked with an oscilloscope. All electronic parts together cost about $12. This device is save to use because the very low current. With a body resistance of 50 Kohm by dry skin the average body current is less than180 micro ampere. However people with body implants should not use it. When the device does not meet your expectations, it's not mine nor anybody's liability. Happy building!
