Zen, mislim da sigurno može ovde umesto otpora da idu namotaji ovih tvojih trafoa? I imamo TVC zdaljinski i rotary encoder, display, milinka jedna.

Mislim da uz minimalne promene, ili softvera ili hardvera, tako nešto može da se izvede?

da ne ulazim u nesto sto me ne interesuje, samo nfo i prestajem.

ovde ima ceo source, pa kome nije gadljivo da modifikuje za svoje potrebe, moze da dobije jednu lepu celinu.

Alexxx , ima li neko cudo od skalamerije koje moze da kontrolise 24 releja ?

Ako je 24 stanja, ova logika iz UGS-a definitivno otpada, jer kontam ne može da se koristi kombinatorika namotaja trafoa kao što on koristi vrednosti otpornika. Kod tvog trafoa ide jedan relej - jedan kontinuirani redni niz namotaja i kraj. Kontam, od svih navoja redno kao 0dB do nijedan kao -~. Sa korakom 24, 24 odvojka sekundara za ukupno 25 pozicija volume?

Može da kontroliše jednostavniji MCU recimo 3 izlaza 8-bitnim stringom, pa 3 MUX-a (CD4051) = ukupno 24 releja.

Mogu nešto da probam...

24 izvoda , plus jedan za masu

prakticno 24 releja , uvek ukljucen samo jedan , obavezno pri preklapanju da ima make before brake

à Mbb turn Off delay (Play on the switching time of the volume relays, and minimize clocks at the volume setting).

à Mbb turn On time (The volume relays are activated one after the other, with an adjustable time interval. It allows to refine the previous setting if necessary.)

je li to ovo?

isto kao kod me'anickije' preklopnika

 

mbb - kratkospoji dva susedna kontakta pri prebacivanju

bbm - odspoji napustajuci pre nego spoji nadolazeci

 

samo analogija na releje i to je to

Sad jasno... za neupucene.
Where aswitch contains both normallyopen (NO) and normallyclosed (NC) contacts, theorder inwhich they make and break can be significant. Inmost cases, therule is break-before-make or B-B-M ; thatis, theNO and NC contacts are never simultaneously closed during thetransition between states. Thisisnot always the case, Form C contacts follow this rule, while theotherwise equivalent Form D contacts follow theopposite rule, make before break. The less common configuration, when theNO and NC contacts are simultaneously closed during thetransition, ismake-before- breakor M-B-B

Mi kad smo pustili u rad uc controler, on koliko videli MBB ima podesavanja u us...nismo testirali vec videli samo da ima ta opcija. Ono sto sledi jeste pustanje u pogon svih delova i onda igranje sa tim.

ako planiras to za tvoj iron preamp, pogresno je spojiti sledeci rele pre no sto odspojis prethodni jer pravis kratak spoj na tom delu namotaja
