Interest Check: AMB's Y1 DAC

Recommended Posts

enclosure get from digikey/farnell/mouser.

like what mouz said, he will not be providing the full kit as it is too messy.

faceplate i bought from AMB himself. the current face plates are selling at 40USD i bought at 20USD so that was ok for me.

 

after building it i wouldnt say its much easier then the mini3.

this one has the huge hassle of testing every single smd chip for shorts before you power on and due to this many smd chips? its very very easy to bridge them with solder or have cold joints. i also spent many hours just trying to remove the solder bridges.

 

Bro, where you get the face plate? can share the contact?

 

Oh...where you get the power supply ?

Wow, how to get faceplate so cheap, unless custom lasercut in SG with plastic plates.

 

I would say it is not much more difficult than the Mini3 because not so easy to spoil the chips. I had no problems with solder bridges. The way to clean off the solder bridges is to clean all solder off the iron tip with a wet sponge, dip the tip into flux and then wipe it across all the leads slowly. The solder will melt and be wicked onto the iron tip. Viola, no more bridges.

 

Checking with DMM for cold joints can't be helped but is not difficult, just time consuming. And with a lot more parts than the Mini3, need to be careful.

The y1 don't need a power supply, it can run off USB power. But if you wish, you can buy a 5V wall wart to power it.

Hi Stephen MKT370 film cap no more already, it has been replaced by mks2 which is $USD0.80 each which works out to be $USD2.40. BTW, take note all prices are in USD.

Don't worry Heady, I'm pretty sure the ones we'll be making will be much cheaper than USD20 :)

I can organise the group buy for enclosure. Will create a new thread to check how many interested. I'll try to find out which vendor offer more discount if we buy more.
