As title says, im looking for some nice relay based 8 source selector. :roll:
Any suggestion? I must admit that logic circuits are little boring to me, but what to do , i need this for my mastering console :wink: project is still on the paper, includes MCS digipot, waiting for buffer to choose, and lot of relay switching.... If somebody already made some PCB plans for selector ,will be great :!: :green: :guinness:
 
Well, you already have my suggestions :green:

Best regards,

Ok, i will talk in public about my ATMEL fears :!: Mikkel you are really genius guy, and big fan of chip programming, but i hate to ask for your knowledge and skills avery 5 mins, so i tried to ask some of other guys for maybe me-closser solution :roll: Anyway, im afraid that ATMELS will jump all over my studio :grin:

Don't worry! Use super glue :grin:

Here is my circuit BTW: http://stiftsbogtrykkeriet.dk/~mcs/MOBY.pdf

It could be done with standard logic circuits, but I find it easier to write a bit of C-code instead of trying to think... :wink:

As i said before, you are software fan . I think that is rare passion around audio related DIY, but nice to know you. BTW, if ask somebody around me to write something, what i have to ask? C-code? C++ :?: Simply, what kind of programmer i have to ask?
 
Of course, CJ you are analog kind of guy, like most of us :wink: No tranformers around no valves and other cookies :roll: Do you know some tube-based vintage switcher :wink: :green:
 
BTW, what happened with T4? Now i must ask Mikkel to make some c -based algorithm emulatng T4b :green: :green:
 
[quote author="cjenrick"]Who makes a burnable chip that uses C?
This Microchip PIC language is a pain.[/quote]

Still, i think MIOS can do a lot here too in terms of control - MCS, have u checked out that C wrapper for it pilo kick started?
 
"Tube based switcher"
Of course:

First ever electronic calculator-1962-all tube of course:

112 tubes!
What a waste of Mullards.

Logic anybody?

But my favorite is this 1950's era $39,000 dollar beauty-the computer I mean.
39,000 is cheap, considering the typical mainframe back then cost $200,000 and took 3 to 10 people to maintain.
Looks like that dirty snauzer is looking right up her "no good"!

Do you know some tube-based vintage switcher

There was this fully tubed MIDI interface a while back, I forgot where i saw it... maybe they do switchers as well.
May have to wait to the next April first though before they can deliver.

Man! I just joking about tube switcher :oops: CJ will understood. :wink:
BTW, I really need some nice 8 source switching circuit, Cmos or something without PIC programming.
 
Hey

mcs, is this able to take a single audio input and route to 1 of 8 outputs via those takt switches ye? So for instance it could be used for a group selector in a mixer config?

Ta
 
It's a standard "radio button" type of thing (just like input type=radio :wink:). So when you press button 1 relay one turns on, press button 2 relay one turns off and relay 2 turns on etc.

So I guess you could use it for a lot of things, depending on how you wire the relays. I updated the schematic with an extra feature BTW...

So daArry, do you want a chip as payment for the crystals?

Perhaps a Yamaha PLS 1 could be adapted, or else look for old step by step or crossbar telephone exchange switchgear.

are u able to have more then 1 button pushed at a single time? So it'd send the same signal to whatever outs assigned?

Cool, that IR option eh? speaking of which I have a cpl of these IR sender/receiver thingies which contain two IR emitter LEDs and one L14C1. Mebbe could use them?

eheh the knowledge is all good :thumb:

You could just change the code to push-on push-off. Perhaps use a pin on the chip to switch between the two modes?

Perhaps, but why? The IR receiver modules like the Siemens I use are very cheap and a lot easier to use than the old photodiode/preamp/bandpass/demodulator circuits. And when you can buy good quality remotes on eBay for £2 why DIY that part :grin:

coo thinking about it then, this be more ideal for use in the GC amp i done - atm i've only a single balanced in which is fed from the DAW, so whilst i'm workin on the d/a and mixer shiz it'd be nice to have a few more inputs on the amp and be able to remote control :thumb:

Im not sure what is PLS 1. Any schemo about?
Thanks :thumb:
