Preporuka za ESR, RLC - metar - acavplana - 02-28-2014
<p>Evo kako izgleda moj primerak:</p>

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

<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.</p>
<p>Konstruisao ga je neki Madjar. </p>

<p>Ja sam zainteresovan da napravim ovako nešto ukoliko je moguće naći sve delove...</p>

<p>@TDA Hehe, opet dolazis u isti problem, gde ti je programator za PIC?
</p>Preporuka za ESR, RLC - metar - TDA - 02-28-2014
<p>U kompu. Još ga nisam napravio...
oh: </p>Preporuka za ESR, RLC - metar - acavplana - 02-28-2014
<p>Bez programatora nista
</p><p>Jednostavan je i vrlo lak za izradu, mislim na RLC metar.</p>
<p> </p>
Preporuka za ESR, RLC - metar - acavplana - 02-28-2014
<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>

Preporuka za ESR, RLC - metar - HSP - 02-28-2014
<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>

<p>To je ta sema.</p>
Preporuka za ESR, RLC - metar - samuki - 03-01-2014
Umjesto Tl084 da li moze mc3403 taj imam i gledam raspored nozica isti je ? Ili lm324?
Preporuka za ESR, RLC - metar - HSP - 03-02-2014
<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>dobar prijatelj kaže da sprava stvarno pouzdano i dobro radi.</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>

<p>@acivoj Zanimljivo. Samo kad bi imala negde verzija sa PIC umesto Atmela …</p>
Preporuka za ESR, RLC - metar - acivoj - 03-03-2014
<p>U čemu je fazon sa ne-Atmelom?</p>
Preporuka za ESR, RLC - metar - mikikg - 03-03-2014
<p>Pa nije nista sporno ali ih bar ja ne uzgajam niti imam programatore za njih

<p>Zar ne može neko "privremeno" rešenje sa LPT porta?</p>

<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> </p>
<p>Pored testiranja i merenja komponenti spominje se generator funkcija i frekvencmetar.</p>
<p> </p>
<p>Naručio sam atmega328 i prvo ću da uradim programator i izučim kompajliranje.</p>
