ab Posted November 30, 2015 Report Share Posted November 30, 2015 U ocekivanju EVO teme - evo kolegama koje interesuje jedna tema koja opisuje potragu, adresu, dokumentaciju, fotografije i nadam se konstruktivne diskusije do gotovog proizvoda jednog single-rail PSU koji je u svakom smislu sve ono sto jedno napajanje sa visokim performansama treba da predstavlja. U ovoj temi bavicemo se prvenstveno Sigma 11 single-rail PSU iz prve ruke, a mozemo napraviti osvrt ili ako neko ima licnih i prakticnih iskustava sa ostalim dostupnim projektima koji su kompletno predstavljeni na sajtu: AMB Laboratories http://www.amb.org/audio/ ... je podigao sajt gde se mozete informisati, upoznati, prouciti, dobiti potpuno slobodan pristup (Open Sours) kompletnoj dokumentaciji i uputstvima za izradu DIY projekata koji su osmisljeni, ostvareni i provereni u praksi uz punu tehnicku podrsku vlasnika sajta Ti Kana http://www.amb.org/ti/ i online prodavnicom https://www.amb.org/shop/ gde mozete naruciti najvaznije komponente, a za sve otvorene diskusije i razmenu informacija tu je i forum http://www.amb.org/forum/ kome mozete pristupiti i aktivno doprineti razvoju postojecih ili mozda novih projekata. Dakle, Sigma 11 single-rail PSU: http://www.amb.org/audio/sigma11/ U levom delu ove stranice postoji meni za navigaciju kroz kompletan projekat i dokumentaciju kaja Vam je potrebna, pa ako imate interesovanja pogledajte malo o cemu je rec, pa mozemo malo prodiskutovati.

ab Posted November 30, 2015 Author Report Share Posted November 30, 2015 U svakom slucaju, plocica je skockana i testirana. Najlepse od svega sto je sve iz prve proradilo kako se zapoveda: http://www.oldschool-samp.com/slike/?v=imag12cvc.jpg Sledi skutijavanje, a pre toga finalni raspored iznutrica: http://www.oldschool-samp.com/slike/?v=dscn54lel.jpg Shema u prilogu takodje: sigma11_200_sch.pdf Quote Link to comment Share on other sites More sharing options...

Aleksandar75 Posted November 30, 2015 Report Share Posted November 30, 2015 Pa to ti kažem, minimalizam i deluje brutalno, a ne neki fensi dizajn za fićfiriće 'oće biti srebrna kutija da se slaže sa kockicama? Quote Link to comment Share on other sites More sharing options...

ab Posted December 3, 2015 Author Report Share Posted December 3, 2015 Sto se tice nabavke potrebnih el.komponenata, AMB Audio shop - spisak sledecih potrebnih komponenata: Items Display filter: Show all items By project: CK²III headphone amplifier By project: LCDuino-1 display I/O processor By project: Mini³ portable headphone amplifier By project: M³ headphone amplifier By project: α10 stereo pre-amplifier By project: α20 line amplifier By project: α24 fully-differential line amplifier By project: β22 amplifier By project: β24 fully-differential power amplifier By project: γ1 modular miniature DAC By project: γ1.5 miniature high resolution USB DAC + headphone amplifier By project: γ2 compact high performance DAC By project: γ3 high resolution DAC By project: δ1 relay-based R-2R stereo attenuator By project: δ2 relay-based stereo input/output selector By project: ε12 delay/muting/protection for headphone amplifier By project: ε24 power switch driver circuit By project: ε27 volume control pot mounting board By project: ζ1 audio widget asynchronous USB-I²S module By project: σ11 single-rail regulated power supply By project: σ22 dual-rail tracking regulated power supply By project: σ24 transformer mounting board By project: σ25 regulated power supply By project: χ1 Li-Po battery board for Mini³ By type: Circuit boards By type: Connectors, Jacks By type: Crystals, oscillators By type: Discrete semiconductors By type: Integrated circuits By type: Panel components By type: Passive components By type: Thermal management (Related projects: M³, γ1, γ2, γ3) Description Price (USD) Quantity Notes σ11 single-rail regulated power supply printed circuit board $12.00each PSU for M³, γ3 and others Aavid-Thermalloy 529802B00000 1.5" extruded TO-220 heatsink (3.7°C/W) $2.00each 4 needed per β22 board 4 needed per σ22 board 2 needed per σ11 board International Rectifier IRLZ24N power MOSFET (TO-220) $3.50pair 1 pair needed per σ11 board 1 needed per ε24 board BC546B NPN 65V small signal transistor (TO-92) $0.20each 6 needed per σ22 board 3 needed per σ11 board 3 needed per ε12 v2 board BC556B PNP 65V small signal transistor (TO-92) $0.20each 6 needed per σ22 board 3 needed per σ11 board 2 needed per ε12 v2 board Semitec E-202 2.0mA current regulator diode (DO-35) $2.30each 2 needed per σ11 board 2 needed per σ22 board Semitec E-562 5.6mA current regulator diode (DO-35) $2.30each 1 needed per σ11 board 2 needed per σ22 board BZX55C12 12V 500mW low noise zener diode (DO-35) $0.25each 8 needed per β22 board 8 needed per β24 board 1 needed per σ22 board (certain output voltages) 1 needed per σ11 board (certain output voltages) 1 needed per Mini³ board Wima MKS2 1µF 63V MKS film capacitor $0.90each 2 needed per α20 board pair 7 needed per β22 board 6 needed per β24 board 4 needed per σ22 board 2 needed per σ11 board 13 needed per M³ board 1 needed per ε12 board 3 needed for γ1 full config 1 more for γ1 USB-to-S/PDIF converter or full++ config 2 needed per γ2 board Kemet/Evox-Rifa MMK 3900pF 63V MKT film capacitor $0.38each 2 needed per σ22 board 1 needed per σ11 board Najbitnije su regulator diode naruciti preko AMB Audio shop-a jer ih necete nigde naci, a pored toga naravno i plocica. Napomena: dostava sa teritorije USA bez obzira na kolicinu i iznos je 30USD. Veci deo preostalih komponenata narucio sam iz Farnell-a: http://www.farnell.com/ Ovde obratiti paznju da se naruci ono sto je na stock-u iz EU i za sve takve dostava se naplacuje 5evra, dok se komponente iz stock-a iz USA to naplacuje 25USD. Inace, sve je preko Farnell-a profi, naruceno stiglo za 1.5dan i maksimalno profi upakovano i obelezeno. U mom slucaju, iz AMB-a sam zajednicki narucivao sa kolegom sa DIY foruma, moja kostala 30USD, dok smo postarinu od 30USD preraspodelili on 2/3 ja 1/3 zbog kolicine koju je on narucivao. Porudzbina iz Farnell-a placena 20evra. Za skutijavanje, videcemo. To prepustamo kolegi Leonardu profesionalcu. Kada leonardo zavrsi slede utisci i zapazanja.

ab Posted January 31, 2016 Author Report Share Posted January 31, 2016 Pozdrav svima Iako nema interesovanja za ovu temu red je da ipak postavim par fotosa ucinjenog: Cilj ispunjem, uticaj na zvuk ucinjen. Bice prilike ovih dana, nadam se, kada se ispune uslovi i da obaveze dozvole da obavimo uporedni test sa originalnim M2Tech-ovim baterijskim napajanjem i sa jos jednim DIY napajanjem by Impuls.
