I have been designing an oversampling DAC for the past year, year and a half (in my rare spare time) and I have been thinking about input and DAC clock variances... I mean if the speed of the input clock is off even by 1% we are talking 441 error samples a second in a simple 44.1kHz...

I find SMD much easier to work with, especially when doing the PCBs myself as well as the soldering - 0603 with good twezers is no problem at all even though the tip of my soldering iron is bigger than the part Making PCBs with through hole - drilling and through hole plating - is a pain in...

I make my own boards using photolithography, takes about an hour - hour and a half for a double sided through hole plated PCB. And yes you can do those yourself, you can do mechanical through hole plating using though hole rivets like these http://www.megauk.com/through_hole_rivets.php -...

I give it to them straight - my friends and family already know i'm nuts, and newcomers will learn it sooner or later anyways - and I rather enjoy having a rep for being nuts, lets me do whatever I want without people bugging me about it

High res ok lets see there is: A UV exposure unit (UV202E) A PC powersupply A Soldering station - nothing wild but it has tempcontrol and stuff Asorted chemicals (NAOH, Fe3Cl, Flux, Strip, somthing for tinning) A bottle of water A couple of drills, one in stand An electric saw...

Its starting to look that way... I've been working 100 hour weeks for more than 5 years now trying to get a business going, this year will tell whether it succeeds - it is finaly starting to look up; we have signed with some major customers that we hope will open the doors to the rest of the...

well 12Mb is enough even for 192kHz 24bit - that only adds up to 9,216,000 bits per second but the problem might very esily turn out to be getting the mcu to put the data onto the I2S bus fast enough and not just that but at the precise speed required for the sampling rate in question

Kidney stones are real evil - they come in a close third... second I had some really evil pain down my spine and down the front in the middle - left me hyperventilating in excruciating pain - they doctors got quite worried but they never found the cause - i'm still guessing it was a bad...

I had the same problem a while back - I contacted creative and after a bit of debugging they asked me to send the analogue card back and they sent me a new one. They were very nice about it and it was no problem.

well lets see there is the Monica http://www.diyparadise.com/ the DDDAC http://www.dddac.de both non-os using TDA154x chips built a dddac mk 2 myself and i like it but it isn't exactly cheap i'm sure there are som os dacs out there too but all the ones i have in my links collections...
