multiZAP assemblance

multiZAP - montaż

Below describes how to assemble multiZAP, which is a basic version of te bioresonsnce device. In spring 2018 few additional parts can be added to asssemble multiZAP+. Differneced between this two devices can be found @ forum. multiZAP has an extensive design and can be used in conjunction with mat, electrodes and coils. Additionally, it can be manually controlled and used with heart monitor (biofeedback). 

Its capabilities are grater than free-PEMF  when used in conjuction with mat and yellow coil (used for bioprogramming). To find out more please watch the following webinnar: webinarium .

Following feedback from workshop attendess, concept of sharing information on how to assemble devices have been changed. All relevant information will be now available on YouTube. Detailed documenation will be created in PDF format for the first workshop and will allow me to introduce less chnages to the website. Po warsztatach umieszczę taką instrukcję na portalu jako załącznik, aby każdy mógł z niej skorzystać.

Lista potrzebnych materiałów  - dodac liste po angielsku

List of materials necessary to assemble the device: has been iattached at the bottom of the webpage. It is adviced to print it off and purchase parts in the specialist electronic shop  ot use, allegro, ebay.

1. How to make a beam

Wiązka multiZAP


2. How to make chasing and other construction elements has been describeled in the film.

Soldering of the goldpins for the Arduino modul and the display.

Getting started on chasing and main circuit board.

3. Opis kompilacji i załadowania oprogramowania sterującego urządzeniem.

Po aktualizji oprogramowania do wersji finalnej wrzucę instrukcję filmową, bo docelowo planujemy używać web-loadera do wgrywania softu oraz terapii (plan na 2018). 

4. Main Circuit board

Assemble main circuit board using the below flow chart and film.

5. Cables and LCD assembly


6. Getting started and calibration

Getting started and LCD contrast adjustments

Calibration of the mat and coil.

At the end add cabe no 4 connecting A6 Arduino with slot F1 located at the top left hand site circuit board and assemble the casing.

Added 2017-12-30 - Necessary changes in relation ot the verion described in the film:

1. Cables of the dataway should be connceted according to the table below:

Dataway I2C (until 2017-12-26 flow chart included an error):

Sygnał Arduino LCD


Kabel Uwagi
SCL A5 SCL 9 J17(lg) - G9(pd) lg - lewa górna płytka
SDA A4 SDA 10 J16(lg) - G10(pd) pd - prawa dolna

2. It is necsessary to conncet clip reset AD9850 to slots  B6-B7 right bottom circuit board. Lack of this may cause unstable work of the generator. Sometimes it restarts on its own.

7. Flow charts

7.1 Keyboard and powering flow charts

Device can be switched on after selecting # key for as long as it takes for the Andruino to start up. Then # key can be released. This solution doesn't require additional switch key and enables devic to switch off after therapy has been completed. When the device is on standby the quiescent current is 54uA. When the device is stored for over a month, the acumlator must be disconnected by removing fuse from the main circuit board as when battery become completely flat it will cause damage.

7.2 Display circuit and measuring voltage of the battery charge.

Display can be controlled by highway I2C module 1602. Potentiometer located on the module has been installed to change the settings of the contrast for the display. Voltage of the charge is measured by bridge circuit R10 and R11. They measure voltage at the analog access A7 Andruino. This setting is similar to one used within Free PEMF device.

7.3 Signal generator

Output signal for mat and electrode is generated within module AD9850 and AD9851. Navigation is occuring through A1,A2 and A3 exits. Module is powered by dedicated voltage stabilizer 5V L7805. Pulsating sine wave (unidirectional with fixed component) leaves at exits marked ZOUT, and rectangular signal comes from inbuilt comparator on exits QOUT. Potentiometer included within a module has been made to set up the treshold of the comparator and to match relevant level of square signal.

7.4. Coil and mat circuit.

When using multiZap device you mustn't use coils with resistance lower than 20 om without attaching relevant attenuator. Output signal generates approx. 150-180 kHz signal. Higher frequencies require use of coils of the lowest inductance, which contains small number of scrolls.

7.5. Electrodes circuit.

Circuit of the electrodes has been design to prevent short circuit. Resistors R8 and R9 are acting as voltage divider and measure signal leading to electrodes, which is measured at input to A6 Andruino. Measuring the voltage allows to calibrate the device.

Pomiar napięcia pozwala na kalibrowanie urządzenia tj. parametryzowanie rejestrów potencjometrów elektronicznych układu scalonego DS1803, które są sterowane przez magistralę I2C. Potencjometr numer 0 służy jako dzielnik napięcia wzmacniacza operacyjnego regulacji jego wzmocnienia, przez co steruje wybranym parametrem Vmax-Vmin. Rezystor numer 1 ustawia napięcie odniesienia - reguluje Vmin. Pozwala to na ustawianie wybranych przez użytkownika Vmax i Vmin niezależnie. Minimalna wartość Vmin wynosi od 0,2 do 0,5 V w zależności od specyficznych własności posiadanego układu AD811. Maksymalnie Vmax można ustawić na 12V. W urządzeniu multiZAP+ (opis pojawi się w 03/2018) zostanie dobudowany układ pomiaru napięcia na rezystorze R7 co pozwoli mierzyć prąd płynący przez elektrody.

Added 06-12-2018 - mechanical switch

Few users reported the device had an unusual way of switching on. This caused for the device to work incorrectly. I have personally build number of devices independently and whilst running multiZap workshop and I have never experienced this problem. Therefore the below presents how to redesign the device to include manual switch (with 2 on and off positions).

 Swictch muct be fitted within case and follow the below steps:

1. remove parts marked in orange
2. Exchange diode to jumper
3. Solder cables to the switch and connect them to places marked in red.


The device can be switched on and off by holding # and turning a manual switch.
