Gamma-2 (γ2) DAC Thread

Hi,

Just thought I should share something with you guys about ordering parts from Mouser.

It may be different for you guys in the US but I had a real problem. I won't go into the details cos it's boring. Anyway, it seems they are overcharging for USPS postage and also place a "reserve charge" on credit cards. They wanted to charge me US$25 for USPS but AMB only charged me US14.20 for a larger and heavier order.

It may be that AMB is simply wonderful...true diy paradise....I'm sure we all agree to that eh ?...Thanks Ti ! Simple words but really, thank you.

Unfortunately it does make Mouser something of a less-than-fair supplier in my experience. Incidentally, neither Farnell or RS do this and their customer service has been really good too.

USPS has a lot of different services and options

Yes, and in Mouser's defence, their parts prices on some things are the lowest. However, the USPS service AMB chose is quicker and cheaper than Mouser.

So I thought I'd share this because many ppl don't bother to read terms and conditions or find out about the 'correct' cost of shipping.

The only other places I know that do reserve charges are hotels, and for them I can understand why, but for Mouser, I can see no reason. Of course, everyone should check their credit card bills thoroughly, but again, many ppl I know don't.

So it was just a heads-up.

For most countries in europe, orders over 75€ qualify for fedex free shipping, so it pays off to order a few exra things and get the free shipping!

....poor Europeans will pay import duty on orders over, IIRC, 50 euros, and that's around 15% depending on the country. In my home country, the delightful Royal Mail will, if they are not on strike, hold the package and charge the recipient a fee on top of the import duty.

I dunno if FedEx UPS DHL etc also do this. I've never had to suffer such a thing.

Do you know any way around this for Portugal ?

Orders from mouser are free of shipping cost and all other taxes (paid by mouser) except VAT. You just need to buy for an amount of money. So the best is to order for more projects to save money!!

Yes, we EUs have to pay all sorts of taxes!!! Every package that I got true USPS was inspected and hold by our major post office and I had to pay in most cases only VAT.

:\ be thankful you have mouser to rely on.

i always cry when i have to pay an arm just to order special parts from the US.

Does anyone have a link for a power cable for the gamma1/2 (preferably from mouser). Because I want to make a sigma25 for it with the same output jack as the gamma inputjack, but I can't find a cable with these plugs.

 

[MisterX]

Try
# 172-4206 (plug with wires)
Or
# 1710-1321 (plug)

Many thanks!

Hi, I'm using Y2 for over two weeks now, I have small problem. When powered from power supply (sigma 11 5.02V) or usb with usb selected as input this happens.
In the kitchen I will open my refrigerator to get some filtered water and water pump will kick in or when I open and close microwave door music will stop playing. Audio system is in leaving room, kitchen is behind. I'm using linux slackware on d610 here is dmesg:

Code:

I'm using mplayer to play *.flac or *.mp3 and when it happens mplayer returns this:

Code:

[left][AO_ALSA] alsa-lib: pcm_hw.c:485:(snd_pcm_hw_status) SNDRV_PCM_IOCTL_STATUS failed: No such device [AO_ALSA] Cannot get pcm status: No such device[/left]

This doesn't happen when laptop is running on battery powering Y2.

It looks like Y2 resets it self. Any ideas why this happens ?

Thanks

What happens to the output from the Sigma 11 when you get water out of the fridge or open the microwave?

nothing, it's steady 5.02V, I also tried sigma 25 with 4.98V. When using coaxial as input this doesn't happen, it's weird to me

 

[Beefy]

Your computer is probably dropping USB power then. Even when powered externally, the PCM2707 wants to see 5V at VBUS.

I'm looking on schematics and for U2U I used 771-AHC1G08GV125 instead 595-SN74AHC1G08DBVR but that shouldn't have affect, right ?
