Projekt je sufinancirala Europska unija iz Europskog fonda za regionalni razvoj – Zajedno do fondova EU


Naziv projekta: Razvojna ispitivanja EEZ BB3 modularnog programabilnog višekanalnog izvora napajanja za potvrdu električnih karakteristika i usklađenosti s sigurnosnim normama.


Opis projekta i cilj: EEZ BB3 je modularni koncept potpuno otvorenog dizajna (tzv. open source i open hardware) koji nudi naprednu funkcionalnost koja se može naći u testnim i mjernim uređajima vodećih proizvođača, ali po prihvatljivijoj cijeni ciljanoj skupini, a to su hobisti, đaci i studenti, obrazovne ustanove, mikro i mala poduzeća s ograničenim budžetom koji su zainteresirani za lako nadogradiva i modularna rješenja s atraktivnom programskom podrškom kao što je slučaj s EEZ BB3.

Predmet ovog projekta jesu razvojna ispitivanja osnovnih EEZ BB3 modula (AUX-PS, MCU i BP3C) kao i prvih perifernim modula (DCP405, DCP405B i DCM220) što u cjelini predstavlja programabilni višekanalni izvor napajanja.

Ispitivanja koja se žele provesti trebala bi potvrditi željene naponske i strujne karakteristike, razinu preciznosti u postavljanju i mjerenju izlaznih parametra, sigurnosne aspekte i ukazati na moguće nedostatke kada je u pitanju elektromagnetska kompatibilnost. Za vrijeme ispitivanja pokušati će se otkloniti pronađeni nedostaci, ali isto tako napraviti i određena poboljšanja na koje bi nam stručni tim Končar Instituta mogao ukazati.


Ukupna vrijednost projekta: 39.075,00 kn (od čega EU sufinancira 27.352,50 kn)

Razdoblje provedbe projekta: Siječanj – Ožujak, 2020.

EEZ DIB Projekt je sufinanciran sredstvima Hrvatske agencije za malo gospodarstvo, inovacije i investicije (HAMAG-BICRO) iz Programa provjere inovativnog koncepta

The EEZ DIB project is co-financed by the Croatian Agency for SMEs, Innovation and Investments (HAMAG-BICRO) from the Proof of Concept Program (PoC7)

The EEZ DIB represents complete software and hardware framework for making a new category of modular test and measurement (T&M) equipment positioned between entry-level/hobbyist and professional solutions combining their best features. Demand for T&M solutions is constantly growing and that is in line with our technological and communication orientation.

Potential users of T&M equipment are no longer coming just from the various advanced research laboratories, standards institutes and quality assurance, etc. Because of the ubiquitous nature of many technological achievements, hobbyists, students, educational institutions, micro and mini companies have at their disposal technologies and devices that were almost unimaginable a couple of decades ago. They represent the target group for EEZ DIB concept.

Professional T&M equipment providers still offer solutions that are too expensive and closed/proprietary type (often patent protected) and therefore unattractive for the widest group of technologically involved users. Because of that a large number of simple devices have emerged from the target group, which, apart from low price, are often offered as “open source”, which is the reason for their quick and wide acceptance.

However, there is still no specification/platform that would be the basis for easier and faster creation of new open source T&M devices, as well as their interaction or communication with other T&M equipment and systems, regardless of the degree of complexity and cost.

EEZ DIB is an attempt to create such a platform with building blocks that will enable new creators to design more complex and high-quality modular T&M devices while reducing overall development and manufacturing costs.

We rely on comments from online contributors to aid us in developing our experiments and contemplating the results.


Easy ɸ – a new electronics platform aimed at physicists. It was originally developed for experiments in quantum optics, but is also perfectly adapted for other applications in physics or biology. In particular for time correlated measurements, where high speed electronics is needed. It is an open standard platform based on open hardware and open software. Unlike for commercial systems, you can fully control the platform and adapt it to your needs.


Journal of Open Hardware publishes papers and reviews on technical, legal, economic, and sociocultural aspects of open hardware design, fabrication, and distribution. Its primary goal is to promote research and development of professional, academic, and community-based open hardware projects.

LOGbook (Leslie Green) – home of Harmonics Lab, a Windows program that produces up to 30 bit data to emulate an acquisition system. You can then add harmonic distortion in the form of distortion polynominals up to the fifth order. The program can easily export the data to ADCPro for FFT analysis, but the primary built-in analysis is ENOB, the Effective Number of Bits.
