Passive (active) preamplifier with selector (motorized ALPS, IR)

Looks very interesting, do you have any left? How much to send to Australia?

 

[veteran]

DQ828, it depends from package weight but usually it's about 10-15$ (registered air mail).

I forgot that i'm changing my hosting provider so here are direct links to selector documentation. I will fix this in a couple of days.

Hi
The links don't work.

I was wondering how much it cost all up? Including the goods.

I finally fixed the problem so links (excluding post #64) should work right now.

DQ828 take a look at the end of page 2 of this thread:

I also found some nice little remote which should fit into this project.

An externally hosted image should be here but it was not working when we last tested it.

speaking of remote...
I have a "wishlist" item. Is there any way to implement a discrete on & off IR code in place of the power toggle? (I like using macro's on my programmable remote to turn on multiple things at the same time)

I'd be fine buying a replacement microcontroller from you...

thanks

If I understood good you need separate buttons (on remote) for ON and OFF (on to turn if selector on, and the other to turn it off)?

yes.
so that the on/off relay (REL1 on CON1) can be turned on by one IR code, and turned off by another separate IR code.

this would be great if you could fit it in the program. I use a universal remote, so I have plenty of buttons and codes I can pick from. I just need the logic in the receiver. (otherwise I was considering somehow using REL2 signal and building some extra logic around them. - but that's a bit of a hack )

thanks for taking a look at it.

Hmm... Error code sounds kind of... Sexy.

Hello,

I am interested in purchasing 2 sets of boards with with all parts if possible for the preamplifier with selector and volume control.

Thanks,
Dominic Maratt

 

[veteran]

Hi djmaratt,

boards and sets are still available.

 

[pellesand]

I built this board this summer but haven't used the remote feature until now. When I tried I found that I mounted the motor driver, BA6418N, backwards (clumsy...). When I tried to remove it, two legs from the IC broke (inside the IC) so I cannot use it any more.

Does anyone know where to buy a replacement part in the EU. It doesn't seem to be in stock at any of the distributors I have used (elfa.se, farnell, mouser,...). Veteran: you do not happen to have a spare one that I can buy?

Not a problem. PM me so I can send you one from my stocs

 

[veteran]

This is my new preamplifier which I'm testing (I'll use it in this project). Seems promising

 

[Arkudos]

Veteran,

What are the differences between this new preamp board and your old board? Are the new boards available yet? I would love to make a set and plug them in to compare the two.
