2io Progress...

by Chris Randall
 



Making nice, albeit somewhat slow, progress on the 2io module, the first Audio Damage hardware release. I now have the prototype in my possession, and am busily trying to break it. It works entirely as expected once we solved a rather silly mistake in chip choice. The original USB audio codec chip we chose reports its power current consumption as 500ma, despite only actually using around 30ma. The iPad won't recognize a chip that reports more than 100ma. So while it worked fine as a USB interface, it didn't work at all for its main purpose.

In any case, initial tests with this current rev with Silent Way and CV Generator show that it works like a charm in those contexts. As a Euro-format iPad audio interface, it is working flawlessly. So, in short, all is well.

We're doing one more rev of the prototype just to double-triple-super-duper check our work, then it's off to production. While all that is going on, we're just getting in to the prototype stage for adm01, so expect some reporting from that front as well, as soon as I have something to show you.

Well, i am pretty excited. I took the modular leap this week placing a pretty big order with Analogue Haven.

Although I have filled more than 2/3 of the 9u case out of the gate, I am saving room for this.

Save another 8HP too, for a total of 12. ;-)

Needs a shallower depth of field, I could almost make out some detail.

I could jiggle the camera a little bit when I take the photo.

OK. 12HP it is. But that is all you get.

I am already learning HPs is precious shit.

just some assurance for the stupid:
the 2io is going to work with iPod/iPhone and iPad?

thanks :)

Power is milliwatts, current is milliamps. Hate to be that guy, but it made me cringe a little.

In a case like this with a set dc voltage the current and power are directly proportional, so while the term is incorrect it's not like the information is bad.

@dyscode: The iPhone/iPod doesn't work with the Camera Connection Kit. This is purely an Apple limitation. When the first beta of iOS4 came out, it worked fine. (My post on the subject, if you'll recall, mentioned that I had tested that fact.) However, by the time iOS4 was released publicly they had turned it off for the iPhone/Touch, and it was only available in the iPad. Nothing we can do about this.

@afreshcupofjoe & @DGillespie: My bad. Corrected. I'm not an engineer.

Still unclear if this will work with iPad or not, will it?
