If you look at the Specs on any Shiit product page, you can see the rated power consumption. Bifrost draws 12 Watts. Asgard 2 draws 30 watts.

...and then I’ll do some arithmetic, take some guesses about hours of usage, and add that to my energyaudit. Got it.

I know what you need. For starters, you need to let that kid out.

I used to tell my mother "I have to grow older, I don't have to grow up". She understood.

Said the boy - "Mommy, when I grow up, I want to be a musician."
Replied the mother, "Now son, you can do one or the other, but not both."

Hey all,

Just a quick update: you may not see a chapter from me this week, since the new board didn't solve the problem with the coaster amp. So now I have a real mystery on my hands. Not a huge one, just a bit awkward as I'm also working on helping get Sol into production, and a couple of other new things. Maybe I'll have it worked out this week, maybe not. If I do, I'll post the final chapter and send the boards out for production.

All the best,
Jason

Update to the update: I am an idiot.

The reason the coaster wasn't working was that the regulators were falling out of regulation. I'm so used to working with LDO regulators these days, I was caught out by the 317s needing a full 3V to regulate. They were just bareeeellllyyy on the edge of falling out of regulation, hence the buzzing-that-comes-and-goes phenomenon.

I only found it after taking the board upstairs and plugging the wall-wart into a different variac (that was set lower than the lab downstairs). LOUD buzz. Turn up the variac: no buzz. The good news is this is an easy fix, the bad news is that it means we're looking at 30V/15V rails, which will reduce the maximum output of the amp a bit, and change some schematic values. On the other hand, if I want to go realllllly simple, I could go to fixed regulators, but fixed regs are pretty mediocre until you go exotic (that is, far beyond the LM/MC7815 series).

So, maybe you'll see a chapter after all!

This coaster amp sounds like it’ll be good fun. Will it come with Instructions for Idiots?

Thanks for the update. You have restored our faith in Schiit Audio Design. Just in time before this unruly crowd start thinking your coaster design prowess is: "this guy can't even design a coaster worth Schiit!"

This is dry well worn humor folks, on a well worn thread named...

Once again, you out did yourself on Lyr3!
Look forward to the coaster amp fun. I just wonder if 30v is enough to really make a frog's, I mean toad's leg jump!

 

[AudioBear]

Thanks for the update. It's really fun standing over your virtual shoulder as you work your way through the development cycle. I'm learning a lot. One of the things I have learned is you're no idiot and you're pretty good at multi-tasking. Can't wait to get my coasters...

Thanks for taking us on the roll a Coaster ride.

Mom always said “Don’t put your nose where it doesn’t belong.”

Really? Obviously you ignored her.

I never put any one on "ignore".

So until such time as you can be an enthusiast...go intercourse thy self. I can hear you now - "Doth mine eyes deceive me?! Didst the Toad just tell me in a most ribald fashion to fappeth mine self in to sloblivion?!!"

Yea. Verily I didst just so. Why? Because I have decided that you are not "hurting", i.e., emotional or other wise. You my little manlet are just being a fooktard. Excrement occureth and to be honest, thy cup runneth over with it.

Thus endeth the ramblin' for this day. I shall now pluggeth in my el cheapo de inexpensive wood cupped (size "B", LOL!) planar toadphones in to the mighty VN², cue up some Sinatra and Mathis and dine upon 24 Del Taco tacos and a 1/2 lb bean & cheese burrito. Cuz I am hungry. And a half gallon of iced tea. Cuz I am going to be thirsty.

Naaah, he'd try to convince you to call Sony and demand they change the color of the LEDs in all their audio gear to suit his tastes!

I wrote (not TYPED) more but decided the words were too "big" and turgid with toadish humour and would cause you to curl in to a fecal positon for a fortnight (fartnight?). If Sir Jason of Stoddard throws me into Hades it shall be have been worth it. But then I will not stop by the Schiit display this week end. If I even get to attend.

Back to Sinatra via the VN²!

I know... I am such an ass of a toad.
