Yup. I know..

Just a helping hand from another DIYer...

The schematic at http://elvencraft.com/ppa/ is intentionally simplified to fit on a single ExpressSCH page. The schematic that the layout file actually synchs to is 4 pages and not very pretty to look at. Most significantly, VI on the pretty schematic represents VL, VR, and VG, the separate rails for each opamp. After the v1.0 prototype is validated I will make a zip of all the relevant ExpressPCB files available for downloading. In the mean time, when in doubt, trust the layout.

You're welcome to suggest an alternative.

I am out of ideas on this myself. I think this is the perfect place for these threads, all things considered, with one exception - the people who bitch about these threads. (Why don't they just trust the moderators? [rehetorical question] Maybe it's time for a "trust your moderators" thread!)

Oops. It's now fixed. Thanks for pointing this problem out.

Tangent noticed a small oversight on the final prototype: the positive opamp rail jumper pads are not square. They will be square on the production boards, to reduce the chance of confusing them with the negative jumper pads.

I updated http://elvencraft.com/ppa/ with the new version. I posted it as v1.0 rather than v0035, hoping there will be no further changes, as I will be out of town for 10 days starting Tuesday and will be busy packing tomorrow.

ETA on boards is mid to late August.

 

[morsel]

The boards are done.

 

[ablaze]

does that mean we can start ordering the boards from tangent?

 

[morsel]

Yes.
