Hi Guys,

Have you seen this thread?


The system consists of three boards.

1) The front panel (display, encoder, IR, RS232, I2C) board
2) Input select board (two required for 4 inputs, four for 8 inputs)
3) Volume control board (one for single ended only, two for balanced). The first version is a series attenuator with 24 steps.

We plan on doing a PGA2310 based board next. The same input and front panel boards will be used.

If you have interest, we are planning on selling as a kit with full documentation available at www.dipchipelec.com

Best Regards,

Dale

yes, i know it and its is interesting to read. But i want to do DIY and learn on it - not buy a kit. And i suspect it will not be very cheap. And i prefer to have full controll over the source code to modify to my needs, not only a HEX file.

I understand.

We plan on publishing all source code. It may not be as much $ as you think.

Best Regards,

Dale

If you descide to publish and make a kind of open source project i would like to build some compatible hardware by myshelf and may descide to buy components like relais board etc. at the point to make it a real audio device. Now i want to play and prototype to learn how things work. Later i may build a device that integrates Nelsons aktive XO, a preamp and a MC controlled multichannel volume controll with ability to adapt Speakers of different effiviency. For me the aim is not in first order to posses an audio device - its more the process of build something and learn on it.

Default APOX is open

Till,

We would be happy if you would like to design something for the APOX family of boards. The only requirement of your board is to have I2C compatiblity. We will even be willing to sell your board on our web site, if you don't already have a business started.

For the I2C commands, the format is very simple
we send three bytes
[ADDRESS][COMMAND][DATA]

If you finished a board, we could easily add your commands into our source code.

Thanks,
Craig Beiferman

I wait for mhennessy publishing some code stuff on http://www.mhennessy.f9.co.uk/

The hardware would be no problem to build, everthing on hand; but i don´t need to use my time to invent the weel a nth time by doing all this coding for the pic. I hope i will find som usefull pieces of pic assembler code or so i can make use of.

Another thing is i want to see if its possible to mate a volume controll, preamp and the active xover Nelson promised us.

Hi everyone,
thanks for posting your valuable informations. Ya Im also waiting excitedly for harvardian and guys to come out with an individual controller board using PGA2310. Maybe 3 pcs of PGA2310s? (6-channels using daisy–chaining) Preferably with mute function? I've just received the PGA2310 samples from Texas. Their sampling program is great and shipment is very fast. Best of all, everything including shipping is free! Now with my samples in hand, Im ready for your boards guys!

Default APOX-3

Hi everyone, the APOX-3 is almost done, but I haven't completed the voltage regulator section.

till,
We are using the burr-brown (now TI) PGA2310. It will be called the APOX-3

Thanks,
Craig Beiferman
