not quite. Basically, think of the top layer being a slab of steel. Then a cut out in that slab, or island that isn't coupled to the steel slab. The motor hangs down on this island. Under that is a 1.25" thick piece of soap stone. This implies that there needs to be a cutout in the soap stone for the motor to hang down, and various other cutouts for the idler and the arm. Then the motor island is bolted down to the soapstone, as is the entire steel plate. Then, there is a constrained layer damping layer of.... IKEA cups? eventually, birch ply. Perhaps a few layers of EAR C-1002 ISODAMP thrown in for good measure, then another 1.25" thick piece of soap stone. All in all, around.. what 150 lbs? heh. The AC motor is controlled via a Mark Kelly kit in fact, an improved "to-be-commercialized" version of what you linked to. It's three phase quadrature drive.. Ironically, I've sorta halted things as I need to shape up the soapstone plinths a bit, as I've gotten the arm board worked out and everything. Then I'll need to complete the birch ply layer.... lots of work, so little time.

Yes, the motor is inside the plinth. Imagine a top plate, then a sub top plate, or island maybe in the middle of the plinth. The motor is attached to that and that drives the idler wheel, that drives the underside of the platter. Then imagine a broken router, oh wait, that's swt61's broken router.. I mean, he called it a "trash router" I think? I'm not sure what you're asking with your last question though. It's pretty much a custom design. I've never been happy with "enough".. I go to the next level of MOAR

I think what Shelly was getting at, that "native support" might work better than something that requires a disc to be inserted.

That and once the older cousins come over and explain to my kids what a PS3 is, mayhem might ensue. I'm not sure I'm ready for the jump from PBS Kids and NickJR games (well, iPhone games too I guess) to a real video game system

agreed. This is why I used a custom island for the motor that isn't connected at all to my steel top plate. They are coupled (non-coupled actually didn't work as well as you'd think), but it's through a massive soapstone block.

aw heck, I'm going to try the Samsung BD-P2500... impulse buyer I am.

yeah, I suppose. I was thinking more along the lines of Samsung-BD-P2500, LG BD370, etc.

speaking of which, I need to buy a Blu-Ray player that has Netflix support. Cheaper the better. Any recommendations?

"Sharper attacks" (by other cats) too

That would be cool. Just flashed my meter and I want to try and see how well the screen capture function works.

anyone here have a copy of FlukeView Forms >3.0?

It seems that there are a wider array of SMD polymer caps, perhaps it would be worthwhile to look into these? What's the pad in the lower right corner for?

Nice! Usualy there is an Elenco option that has both the board and jumpers, but what you got is great. One other thing that might be useful are the grabber probe thingies: Mini Hook Clips - RadioShack.com (these are pretty bad quality, but I'm sure you can find something like them at Fry's)

Perhaps someone else would be more qualified than me on this, but the way I understand it X7R are fine for bypassing, C0G are more appropriate in say compensation or filtering circuits. The latter are "better" though. The difference is the dielectric. X7R have a higher dielectric constant, which results in more capacitance per volume. Thus, X7R are used where the "better" C0G capacitors cannot fit. Also, search for NP0, perhaps that will yield more results.

excellent work! Also, looks like the wall wart on the far right will fit just fine!

hm, tiny little rubber rings........................ maybe his wife knows?

How did this get moved? put the loading networks inside a good ole RCA plug (i.e. RCA jacks instead of bananas).

Ari, how did you choose the capacitor values on the secondaries, was it specified in the datasheet? Also, when doing the external loading like you're doing, some people might have problems with RF pickup. I had an issue with this in my previous house. The only cure was some capacitance on the input.

hey doug: I remember you having a website that you recommend that has a number of test tones that can be burned to a CD.. i've created a few of my own, but would like to see what they offer and what other tones I might add to my CD. Thanks!

I agree with grenert and I definitely wouldn't discount using a C0G bypass. This is even recommended by various chip manufacturers on datasheets.

in utero or ex utero?

hm...

that's not a DIY project oooh, thooose people. Cannot wait for impressions. I think I may have to see if I'm highest on the totel pole to be able to request a pair of the universal 5's for demo.
