Thanks for sharing - this really should get added to the Wiki

[Got most parts and started soldering]

Looks nice. Personally I always try to mount rectifiers so they stand approx 1 cm off the board so that they can dissipate heat better. They not only get the benefit of airflow from underneath, but those thick leads act a bit like a heat sink.

My 9090 boards should arrive any day now - so I'll be starting to build shortly!

Cool ... I see there is a nice consolidated BOM at http://members.multimania.nl/diy9090/page01.htm

[808Micro - Control Surface]

I use the Pulsar system as well and have never had success getting traces that small. You make me want to try again though - I just got my hands on a different laser printer, so maybe I'll try one more time- the "new" one is a LaserJet 4 series, the old one is an ancient Apple Personal Laserwriter 300.

Can't wait to see your finished box. Thanks for blogging!

[808Micro - Control Surface]

I like the look of your control surface! Are you going to have enough room for your Core, DINs and DOUTs in that box?

For the past couple weeks I've been working on a small MB-808 control surface as well. My enclosure is a little Hammond box with a 6.5" x 5.5" control surface. I like to etch boards myself, so I laid out all my buttons on a single-sided board, with numerous headers to connect it sammich-style to a custom DIN/DOUT board. I've spent a lot of time laying out this DIN/DOUT board, and I think I'm going to scrap it. Too many ICs on one board combined with my home-etch design rules (FAT traces, single-sided), and it is MESSY! Plus I think I'll be 2 hours just drilling the damn thing.

So now, instead of home etching I think I'll get my board fabbed by this fine gent at Dorkbot ( http://www.dorkbotpdx.org/wiki/pcb_order ). Since I have much more PCB density at my disposal, I plan to put my buttons and LEDs on the same board as my DIN/DOUT. To fit in the available space, I will probably use SOIC (surface mount) shift registers.
