Remote relay volume control kit.

I bought that ML 38 board.

Wow, where it`s possible to buy such things as a stuffed ML board individually

I found the info in this thread http://www.diyaudio.com/forums/showthread.php?s=&postid=260230#post260230

For some reason the site is not active now. But the board was a real deal at $145 shipped

Display problems

Hello Antonio,

Well, I was surprised that the LCD was not the problem.

1) Make sure there are no bent pins on the PIC microcontroller.

2) I suppose that the PIC could be bad.

So, if the PIC does not have any bent pins, we will send you out a new one.

Best Regards,

Dale

Display Problem

Hallo Dale,
Thank you again for your support.
I have checked the pins of the Pic as well the connection between the connector of the display and the Pic many times, "unfortunately" every thing is OK.
Waiting for the new PIC,
Best Regards.

Antonio

Re: Performance

Peter and Grataku,

Can you tell us what you think about the audio performance of the APOX attenuators boards.

Thanks

jewilson,
The boards worked out of the box, I am surprised that Antonio is having all these troubles.

As far as I can tell there is NO audio performance, as it should be.
Signal gets in and gets out attenuated.
I am still looking for a suitable pre-amp but something different from the usual BOSOZ, I have already explored the BOSOZ and the X idea to my satisfaction.
Maybe I will try one of Allen Wright's tube circuits or my own transformer coupled differential with CCS. I am getting ready to move so it will all have to wait until next year.

I am looking for some suitable connector for the 3 pin headers that do the daisy chain from the apoxIR to the various apox components. I was thinking about using a ribbon cable and some type of press-on 3 pin connectors, if they exist.
Has anyone found something like that?

I have been using Molex C-Grid Crimp connector housings for everything that uses the .1" spced header pins. I use 24ga wire with them. I like them because you don't have to wire the connectors the same at both ends, since they are individually attached. My lcd interface on my microcontroller is dual row on one end and single on the other end, so the C-Grid stuff works great. The only problem with it is that you have to buy a crimp tool to use them. (cheap one is ok, but the c-grid one is the best)

I used a bunch of them for all the connections besides the JST ones for my cdpro2 project.

Do you mean like these?

Or like these in the bottom left corner?

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

Dipchipelec Website down?

I've been unable to reach www.dipchipelec.com this evening. Just thought I'd check it out for any updates (haven't followed this thread for a long time). Anyone else having a problem reaching the dipchipelec website?

thx.

Try

We changed names...

Nice site, but how come there is no link to diyAudio?

 

[Brian Donaldson]

Can some of you veteran APOX builders answer something. My APOX 1 board doen't respond. Do you have to set an adress in the front panel or set the jumpers on the volume board to make it communicate. My IS boards works and the front panel seems to work fine, but no relays change on the volume board.
Yes I know they are silent. I've checked input, output and through impeadance...no change as the front panel counts up and down

 

[Coulomb]

I have left all my jumpers open, I had them all on and I could not get it working. Are you sure you have the I2C bus connected pin to pin? Does the Apox controller recognize the IS1 on power up?

Regards

Anthony

 

[jleaman]

Humm.. i cant wait to get my a-pox from anthony..

 

[Brian Donaldson]

I checked the bus and it's connected correctly. The front board counts from 0 to 255 when you turn the right encoder, so I guess it kmows there's a APOX 1 there. But none of the relays change state. some are high and somw are low. I haven't decoded the patern yet. I have figured out how to mute and unmute with the decoders and it makes no change on the volume board.
Thanks for the hints and keep them coming.

Hi!

Light in the LED when power on? (APoX-1 board).

[Coulomb]

Well it sounds like the PIC may be working but the serial controllers may not be. Did you check with a meter or oscilliscope if the outputs are switching from the serial controllers?

 

[Brian Donaldson]

The input select board works, so the serial out from the front panel must work. The volume board has only 3 IC's, pic controller and 2 relay drivers. One of the leds flashes like it should, but the other never lights. I need to get out my scope and see if any signal is present between the pic and drivers. I find it hard to believe both drivers are dead and I know that serial data is present on board( I have it fed front panel -> Volume board -> Input select and the input select works), so that narrows it down to the pic. I may have to ask for a new one.

LED

Should not one of them light all time, when connected to power?
