<p>Jel neko kupovo i kakvi su savjeti, da li se isplati...?</p>

Dacu ti sve fajlove ako se odlucis, napravio sam ovo cudo i prezadovoljan sam. Meri kapacitet do oko 200mF, automatski prepoznaje da li je otpornik prikljucen ili elko. Meri induktivnost, otpor, kapacitet, esr, curenje kondenzatora.

Konstruisao ga je neki Madjar.

Ja sam zainteresovan da napravim ovako nešto ukoliko je moguće naći sve delove...

@TDA Hehe, opet dolazis u isti problem, gde ti je programator za PIC? Smile

<p>Bez programatora nista Smile</p>
<p>Jednostavan je i vrlo lak za izradu, mislim na RLC metar.</p>

<p>Jedine "kriticne" komponente su zavojnica od 100uH i kondenzator od 33nF koji MORAJU da budu sto boljeg kvaliteta. Ja sam koristio induktivnost izvadjen iz starog Samsung tv-a i kondenzator izvadjen iz nekog monitora, mislim isto Samsung. Oznake na semi su C8 i L1.</p>

<p>Pozdrav ja sam pravio par komada esr instrumenata i jako sam zadovoljan i dan danas koristim jer se bavim servisom,rtv serviseri nisu se mogli nacudit ,radi se o analognom esr metru koji radi na 100kHz i koristi tl084(oscilator,komparator, ispravljac) ima zastitu od kr. spoja i indikaciju kr. spoja,nece biti problema oko fajlova imam negdje iscrtanu shemu i mislim da imam pcb fajl memorisan na kompu.ako neko hoce guglati mislim da je dovoljno potraziti pod ESR METER TL084.Moze se sklopiti za manje od 10eura.</p>

Umjesto Tl084 da li moze mc3403 taj imam i gledam raspored nozica isti je ? Ili lm324?

<p>Ja sam koristio TL084 CN,imas kupit u rs electronic na Dobrinji cijena je oko 2km,za brzu provjeru sklopa moze lm324.poz..</p>

<p>Ima li sličnih(jeftinijih) uređaja po ibejovima?</p>

<p>Dopada mi se ovaj pristup, sipaš i ne misliš. Pored RLC testira i aktivne komponente.</p>

@acivoj Zanimljivo. Samo kad bi imala negde verzija sa PIC umesto Atmela …

<p>Koliko čitam, ovo je ozbiljan projekat na kom se radi i radi i koga ljudi prave.</p>
<p>Zadnji pdf sa uputstvima je pušten juče a nalazi se u arhivi veličine 30ak Mb.</p>
<p>Arhiva je ovde: <a data-ipb='nomediaparse' href='http://www.mikrocontroller.net/svnbrowser/transistortester/'>http://www.mikrocontroller.net/svnbrowser/transistortester/</a></p>
<p>Skida se na <a data-ipb='nomediaparse' href='http://www.mikrocontroller.net/svnbrowser/transistortester/?view=tar'>Download GNU tarball</a></p>
<p>&nbsp;</p>
<p>Pored testiranja i merenja komponenti spominje se&nbsp; generator funkcija i frekvencmetar.</p>
<p>&nbsp;</p>
<p>Naručio sam atmega328 i prvo ću da uradim programator i izučim kompajliranje.</p>
