I'm thinking of using 2 9v rechargeable li-poly.
 

 
 
I see, planning on making it a portable affair?

Yup, no solder required.

Solder fumes are good for you!

 

[wuwhere]

Only if you're a diode.

  I just prefer battery, more isolation. Next is finding an enclosure for it.

What I'm thinking is making an enclosure for the ADuM4160 USB Isolator with the rechargeable batteries and HiFace BNC inside.

 

[Nebby]

I'm personally of the opinion that batteries should only be used for portable applications as any well designed power supply will do just as well

 
You should make sure that the ADuM is compatible with the HiFace, as the ADuM only supports up to usb2.0 full-speed, not hi-speed. I believe I have read reports of people having issues with the HiFace connected via ADuM.

Can you point me to some link on the ADuM-HiFace incompatibilities?
BTW my rig is made up of portable components.

List of USB Devices having problems with the USB2ISO
1. Hiface USB 2.0 - Sound card SPDIF 24bit 192KHz (Reason - must have 480Mbit HighSpeed USB)

 

 

[wuwhere]

Thanks. That device is not the same as the ADuM4160 USB Isolator. They're saying that their product has a problem with Hiface.

USB2ISO is also based on the ADuM4160 USB isolator, so there's a very strong chance that if that product has a problem with the Hiface then the Circuits@home isolator will have the same issue. Of course, you're welcome to test it empirically; if you do, please let us know your experience

It could very well be why it was in the FS.

[Nebby]

That could very well have been the reason

It works just fine with my gamma2, thankfully.

 

[wuwhere]

It could be because the HiFace is using the Cypress EZ-USB which is a high-speed USB device?  I may have to get a Halide Design Bridge.

 

[Nebby]

Not too familiar with the HiFace aside from what little I've read in regards to the USB isolator, so I wouldn't know.

 

[wuwhere]

Its not a true USB 2.0 device then, its not backwards compatible to USB 1.1 and therefore it should not be classed as a true USB 2.0. M2Tech should have specified that important data.
