Evo nađoh nešto na Kelco sajtu: Kelco - Detalji proizvoda - Muški, za jednosmerna napajanja, 5.5mm x 2.5mm, sa žutom zaštitnom glavom i sa uvodnikom WWW.KELCO.RS Deluje da bi možda moglo da bude to, mada je slika suviše sa strane... A i pod uslovom da je u pitanju fotografija baš tog proizvoda.

Spletom srećnih okolnosti do mene je stiglo ovo napajanje koje planiram da upotrebim na mom NUC PC-u: Jedini problem je što untrašnji prečnik konektora nije odgovarajući - na napajanju je 2.1mm, dok NUC zahteva 2.5mm. Ništa lakše neko će reći - izvući ću iz fijoke običan 5,5x2,5mm konektor koji već imam, zalemiti ga umesto originalnog i to je to. Da li je? Originalni konektor na ovom napajanju nije onaj obični "cevasti" sa glatkim zidovima untrašnje kontaktne površine, već unutra ima ovu neku štipaljku, kao ovaj levo na slici: Konektor na napajanju koji je stigao uz NUC takođe ima štipaljku, imaju je i svi konektori na napajanjima za laptopove koje imam u kući, a isto važi i za napajanja za eksterna HDD kućišta. Svima je zajednička veća amperaža. Gugl pretraga za sada potvrđuje moje sumnje, ovaj tip konektora se izgleda upotrebljava za uređaje koji vuku više struje: What type of 5.5mm DC connector is this ELECTRONICS.STACKEXCHANGE.COM I have used a digital caliper to measure inside and outside of this 6v 500ma DC connector 5.5mm outer 2.1mm inner - 12.5mm long Question is, I can't find a connector with these 2 little notches ... Ako ta "štipaljka" obezbeđuje bolji i sigurniji kontakt, koji je bitan u slučaju da napajanje kačim na kompjuter koji vuče više ampera, da li to znači da ne bilo preporučljivo da koristim neki najobičniji barrel plug od 50-ak dinara? Kako se uopšte tačno (stručno) zove taj konektor sa unutrašnjom štipaljkom i gde ga kod nas naći? Na sajtovima Mikroprinca i Silkena vidim u ponudi samo obične cevaste konektore.

E da, sada provalih u onom prvom linku gore, da ima i komentar korisnika koji ovo napajanje koristi baš sa NUC-om, ... i naravno, nebo se otvorilo! Just brilliant I got this after being recently converted to the iFi brand after purchasing the superb USB iPurifier 3. I use this to power my Intel NUC streamer - the DC barrel connector internal diameter is just too small for the NUC so you need to buy a 2.1mm to 2.5mm adaptor for a few quid elsewhere, but this isn't a big deal in the slightest, I'm just mentioning it in case anyone else is looking to power their NUC with this unit (do it). I was sceptical about how much difference it would make, but I really shouldn't have been. Ostensibly it looks like yet another generic switched mode power supply but it's a completely different bit of kit, despite running as cool as the stock unit. It's got a cute white LED which adds a bit of class to an otherwise bland looking unit. But of course what really matters is the sonic performance. I was expecting it to tame the top end of the frequency spectrum, which it noticeably does: it sings rather than shouts now. But I wasn't expecting such a profound difference in the lower frequencies: it truly lifted a veil on the bass and lower midrange, separating the instruments which were previously a jumbled mess, giving better timing, more detail, more rhythm and just more musicality. Low bitrate, high bitrate, whatever, everything sounds better. Kick drum notes now decay with grace rather than falling off a cliff. More air and detail with snare rim shots which can often be a little bright, this pulls it into place. Honestly it's like swapping speaker LF drive units for superior models, more than once I've verbally exclaimed my surprise, which has to be the hallmark of good equipment, and I've been using it for less than 24 hours. The ability to swap IEC mains cables opens up a salivating new upgrade path which I look forward to investigating in due course once I get used to the sound of the stock cable. You can spend way more money than this for much smaller improvement. Buy this in confidence, snake oil this is absolutely not. I don't know exactly what it does or how it works, but whatever it does it does it very well indeed and the guys at iFi and AMR know what they are doing. The only problem is that it makes me want to buy the rest of the iFi catalogue, but there are worse problems to have.

Evo nađoh i neki PDF koji bi to trebao da objasni: https://ifi-audio.com/wp-content/uploads/2018/07/iDAC2-Spilling-the-Sauce-5-of-6_-17-Nov-2015.pdf

Samo da navbavim odgovarajući DC priključak za NUC (ovaj originalni ne ulazi) pa ćemo da vidimo! Voja je kada ga je otvorio primetio svaša zanimljivo, nekakve dvostruke povratne sprege (ako sam ga dobro razumeo, neko kolo koje bi trebalo da ubija smetnje sa signalom u protivfazi (nekakav princip rada kao kod noise cancelling slušalica), itd, itd.

Da oživimo temu! O drugara sam na poklon dobio crknuto iFi Audio iPower Plus napajanje: iFi Audio iPower Plus 15V for Pro iCAN and Pro iDSD | Future Shop WWW.FUTURESHOP.CO.UK Aimed at the iFi Audio Pro iCAN and Pro iDSD, the iPower Plus offers all of the benefits of the iPower however at a higher output rating of 15V/4A with removable IEC power lead to accomodate for different regional connections and lengths. Drugar Voja je upotrebio svoju magiju i sada radi k'o novo. Proizvođač tvrdi da su njihova napajanja bolja od linearnih. Nekakva vojna aktivna noise canceling tehnologija i šta ti ja znam : The central characteristic of iFi is in pursuit of the zenith in audio performance: it leaves no stone unturned. Well, the all new iPOWER is an exemplary example of this. Despite the fact that the iFi Ultra-Low Noise AC/DC adapter was exceptionally quiet and elevated the iUSB and iPhono to punch way beyond their respective categories, the all new iPower is even quieter, up to 10x quieter in fact. Aimed at the iFi Audio Pro iCAN and Pro iDSD, the iPower Plus offers all of the benefits of the iPower however at a higher output rating of 15V/4A with removable IEC power lead to accomodate for different regional connections and lengths. Advanced DC power design – the best has just been bettered Three years ago, iFi’s Ultra-Low Noise AC/DC power adapter set the way and underpinned the whole iFi range from the iUSB to the iPhono leading to their loyal following. Well, not to rest on its laurels, iFi now has a completely new ‘ground-up’ DC powered supply. Active Noise Cancellation+ drawn from military radar technology Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation+ (ANC+) audio power system. It is so good ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range. An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an onboard system to cancel out the enemy radar signal. By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+® is the perfect ‘antidote’ for power supply noise, the bane of USB audio. With ANC+ the power line is filtered for audio band and RF noise. The measured noise floor of 0.1uV (0.0000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of. What audio noise floor? Measured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi’s very own Ultra-Low Noise AC/DC adapter was in a class of its own at 10uV. Compared to a typical audiophile Linear Power Supply which measured at 20uV, it is demonstrably clear AMR/iFi power supply technology is unparalleled. 12-Element Output Array Shaping the face of technology, AMR/iFi not only pushes the boundaries of audio design, but power design too. After all, electricity is the “fuel” behind the audio signal. The 12-Element Output Array dynamically suppresses noise in real-time as it makes its way through the mains. Technology like this is quite simply unheard of in audio power design.

"Čist" je u odnosu na neke od skupljih "hibridnih" VdH kablova sa dodatnim karbonskim omotačem oko vodova, koji zadebljavajući mid-bass, previše farbaju, zatupljuju i šećere zvuk. Moj doživljaj njegovog zvuka je upravo onakav kako je opisan u What Hi-Fi-ju: Power with clarity Refined, detailed sound The appeal goes up a couple of notches thanks to a balanced and involving sound. Play Drake’s Started From The Bottom and the cable helps to reveal great power and depth from bass notes and crisp, far-reaching highs. And it’s all done without sacrificing anything in the way of cohesion and integration. There’s an impressive level of detail, dynamic clout and clarity, but this cable also allows your system’s sense of refinement and finesse to shine through. Verdict Natural-sounding vocals and plenty of layering and texture to instruments really give tracks the ability to communicate effortlessly with the listener. Pošten zvuk sa 0% audiofilskog poreza.

Koristio sam ga i sasvim je OK. Ipak, ja bih za nešto više para preporučio VdH The Clearwater: van den Hul The Clearwater review | What Hi-Fi? WWW.WHATHIFI.COM A cable with an impressive level of detail and dynamic clout. Recommended U Koratu je 1.560 din metar. Čist i precizan ali neopterećujući zvuk, za razliku od skupljih VdH kablova sa karbonom koji ga previše zatupljuju i šećere.

Neki kabl od nekih rashodovanih bubica (slušalica)? Ti su baš tanki i fleksibilni a koaksijalni. Jedino što su baš zbog te tankoće pain in the ass za rad.

Jedino što British Royal Museum ne postoji! Postoji British Museum: British Museum - Wikipedia EN.WIKIPEDIA.ORG The British Museum was the first of a new kind of museum – national, belonging to neither church nor king.

Ova je teška samo 1,6 kg? Na slikama mi sva deluje nekako plastično. Nije mi pri ruci da je izmerim, ali deluje mi da je ćaletova najmanje dva puta teža, ako ne i tri. Na Youtube-u ima gomila snimaka restauracije tih matorih bušilica, pretpostavljam da vrede?

Pričalo se ovde o bušilicama, pa me interesuje kakva je ova što mi je ostala od tate. Mislim da je iz 70-ih godina prošlog veka. Dosta sam je maltretirao kada sam bušio rupe za montažu polica kod klinca u sobi. Sa ciglom je išlo lako, ali sam nekoliko puta naleteo na betonske grede i imao sam utisak da cela zgrada vibrira dok ih nisam probušio (i pri tome bukvalno istopio nekoliko jeftinih burgija). Poštovao sam tablicu brzina i uključio "čekić" mod. Pošto o upotrebi alata ništa ne znam, nisam ni znao na šta treba da pazim, tipa pregrevanje motora, itd, ali bušilica je sve preživela i nije ni trepnula. Evo par slika:

Za moj ukus je slika previše očišćena. Korišćena je neka "AI" tehnologija koju je Džekson razvio za potrebe restauracije snimaka iz Prvog svetskog rata, ali su možda malo jače "odvrnuli" noise reduction kontrole, tako da Bitlsi na momente izgledaju kao da su od plastike. To na momente baš smeta i odvlači pažnju. Doduše gledam 2160p verziju na 4K 55" TV-u sa 1m blizine! Na kompjuteru možda i nije tako strašno.

Sveže sletelo sa interneta na hard disk : Još samo da uhvatim šest i kusur sati slobodnog vremena!

Čudi me da niko do sada nije pomenuo sjajnu seriju Halt and Catch Fire: https://en.wikipedia.org/wiki/Halt_and_Catch_Fire_(TV_series) https://www.imdb.com/title/tt2543312/ Slučajno sam je otkrio na kanalu Nova S kojeg nisam imao u ponudi do nedavno (hvala @shonne!). Upao sam na pola epizode iz sredine neke kasnije sezone i samo par minuta gledanja mi je bilo dovoljno da se potrudim da je pronađem na torentima. Prava serija za kompjuterske gikove i nostalgičare. Scenario, režija i gluma su savršeni, muzika i soundtrack fenomenalni. Velika je šteta što nije imala veliku gledanost, tako da je mnogima, uključujući i mene, prošla ispod radara kada je bila aktuelna. Tada (2014-2017) nije bila gledana a sada Wikipedia kaže: In each subsequent season, the series grew in acclaim, and by the time it concluded, critics considered it among the greatest shows of the 2010s. In 2021, BBC Culture ranked Halt and Catch Fire the 50th-greatest TV series of the 21st century, based on a poll of 206 TV experts. I špica je odlična, pustiti (ko ima) na velikim zvučnim kutijama i odvrnuti glasnoću: https://www.artofthetitle.com/title/halt-and-catch-fire/

Nisam skapirao - Lidlova i nije nešto, ali je ipak kvalitetnija od BAKU, naročito su Lidl vrhovi bolji?

Hvala!

PS Kako funkcionišu te jeftine "digitalne" lemilice? Tj. da li mogu da održavaju zadatu temperaturu tako što potrebi dodaju "gas" ako se lemi nešto masivnije pa pada temperatura vrha?

Gde je 2900? Svugde gde sam gledao je 3500. Pitam zbog druga kome je u Lidlu zapala za oko, a ja ne znam šta da mu kažem da li valja ili ne. Držao sam je uživo i za te pare u ruci ne ostavlja loš utisak (jedino je dizajn jezivo ružan )

@blaidd Hvala za tip! Sa obzirom da mi (od kako sam prešao na HDD based playback) CD plejer skuplja prašinu, upravo skinut FLAC sa Rutracker-a odlično radi posao. Sviđa mi se muzika, puno sreće u pronalaženju originalnog CD-a.

Ima na Rutrekeru 720p bluray rip. Sasvim fino izgleda. @mrcelavi Hvala za tip, skinut juče!

AR-18 su bile prve AR zvučne kutije koje sam čuo i zaljubio se u njih, zatim sam čuo pravljeni AR-9 (drugarima je tata radio u Kontaktorovom servisu i obezbedio originalne drajvere i šeme) i od tada za mene postoji samo AR. U kući na moru mi sviraju AR-17 (hvala @zika !) sve isto kao 18-ice samo u većoj kutiji. Rade odlično, svakog leta se sit naslušam muzike. Te kutije, ako su ispravne i u originalnom stanju, imaju neki šmek koji mi se jako sviđa.
