Once more updated the list with your names, guys. Pls. have a look, if I did it right.
Thanks! Looks good. Hopefully there will be a way to let WIlba know I don't need any YMF262 or YAC512 chips so that he doesn't have to use up any of his stash for me.
-
I'm very happy kits might be available again! Please put me on the waiting list for three sammichFM kits.
And I don't need OPL3 chipsets as I already have some YMF262 and YAC512 from an old buy that Wilba ran.

Mine showed up last week in New York State, USA. Thanks!
-
I received my MIDIbox CV PCBs and chips from the bulk order today here in New York State, USA. Everything was very nicely packaged. It all looks very good.
Thanks, sonicwarrior!
-
You may think I'm crazy (you might be right), but I'd like in for a set. I'm not out of these, but I still have big plans for them. :)
-
My ultracore boards showed up today in New York State, USA looking very nice.
Thanks!
-
I'll take two!
-
Where are my blessed boards!?!?! Oh wait, they're here (United States, New York State) looking very pretty. They just showed up today.
Thanks!

...and in any case i think sonicwarrior has done his best to get
the best deal for everyone involved so its probably a little late in the day to go down this road
Sonicwarrior already has the max525 order in and I wouldn't try to change that. What I was trying to do is let people know I found a possible source of MAX6007B+ which I'd understood are nearly unfindable as the non-RoHS MAX6007B.
Since I was there at Maxim's site, I thought it was useful to grab the price of max525's as well in case anyone who really wants one missed out on the MIDIbox CV PCB (CORE+AOUT+DINX1+Bankstick) + 2 x MAX525 bulk order.
This morning I got email from Maxim that they plan on shipping my MAX6007B+ tomorrow. It looks like they're coming from Thailand (I'm in the US).
I really appreciate how Sonicwarrior has stayed on top of this order in spite of the changing availability and price.

Instead of the difficult-to-get MAX6007B you can use a LM385-2,5. You'll only need to re-calculate some resistor values.
Maxim seems to have the MAX6007B+ which is the RoHS version of MAX6007B in stock and orderable in any quantity from 1 on up for US$1.53 each. I just placed an order for some at https://shop.maxim-ic.com/ with no problems.
The same Maxim site is accepting orders for MAX525BCPP+ which is the RoHS version of MAX525BCPP with a leadtime of 4 weeks at prices of:

Right! the price per unit is not that cheap. I am interested by a styroflex bulk order (need to fill 4 pcbs... 24 x 10nF + 8 x 820pF).
If there's an order, I'm in for enough for 5 boards plus two spares of each: 32 x 10nF and 12 x 820pF

Did any one purchase a few of those $15 12v PS from here?
http://www.skycraftsurplus.com/index.asp?PageAction=VIEWPROD&ProdID=439
Out of stock.
It looks like they've got almost the same thing (same specs, different manufacturer, doesn't have remote sensing terminals) for US$0.05 cheaper with screw terminal outputs:

ugh plastic
Yes, ugh. I bought one of these a month or two ago and not only are they plastic, they're also not very sturdy. I wouldn't use one to rackmount anything with controls or jacks that get used regularly.

The mouser part number 688-SKHHDT I listed have 13mm black 100gf stems/actuators. A little bit but not too clicky for me.
-
The dimensions of the (what do you call that the plunger?) don't quite look right. It's not tall enough. I found all kinds of switches on mouser with shorter plungers, but not any taller ones. Mouser's cheaper though with faster shipping, so I prefer them to digikey.
I've got a bag of Mouser part number 688-SKHHDT which are 6.0x6.0x13.0mm 100gf ALPS tactile switches, RoHS compliant. They're the right size for an MB-6582 which I'm sure of because I've got a few (but not yet all -- sorry Wilba) installed.
The mouser page for these tact switches is at: http://www.mouser.com/catalog/635/1514.pdf
Note that the H column for the switches on that page is the stem height, not the total switch height.
The switch I list has a 13mm high stem. See the ALPS datasheet for these at: http://www3.alps.com/WebObjects/catalog.woa/E/PDF/Switch/Tact/SKHH/SKHH.PDF
On page 3 of that datasheet take a look at the dimensions for the vertical type switch and note that this basic switch is available with stem heights of 4.3mm up to 17mm, though 13mm is the tallest stem that mouser seems to carry.

I am not familiar with Arduino. Do I program it directly with my computer? Serial port?
Yes, you program the Arduino through a serial port. Once programmed, it can work without a computer (unless it's programmed to interact with a computer). Can be programmed from Mac, Windows, or Linux.
The particular links I sent would set up an Arduino to directly output MIDI -- no computer need be involved.
-
You could also go the Arduino route. Here are a couple of examples of switch or piezo inputs to an Aurdino with MIDI output:

http://itp.nyu.edu/physcomp/Labs/MIDIOutput
Note that those don't have optically isolated outputs.
I'm sure there are more out there.
-
Another - very sad - note: it seems that the package I sent to Wilba is lost. Therefore the australians haven't got their order yet. The package contained 46 GM5 chips and 34 PCBs and wasn't insured (damned!), accordingly I lost ca. 300 EUR! :(
Sorry about the lost package and the 300 EUR it cost you. I've sent you a little money through paypal to try to help.

Mine showed up in the US today.
Thanks, Seppoman!
-
I'd be interested in a few of these.
-
Four nicely packaged AY-3-8912 showed up in my mailbox today.
Thanks!
-
Excellent news that the wheels are still in motion. Thanks for all the work you're all doing on this.

Is there any chance the quantities are large enough to deal directly with MEC? I see they have sales / special projects contacts listed at http://www.mec.dk/contact/mec . Maybe it's already known that these numbers are too small to deal with them directly.

I just found what looks like these tactile switches with pre-installed red T1 LEDs for US $0.20 each (US $1.00 for a pack of 5) at Electronic Goldmine. I'm sure they're the clicky ones. I took a chance and ordered 500. They don't have any caps available at Electronic Goldmine. This switch deal is at: http://www.goldmine-elec-products.com/prodinfo.asp?number=G15660
Note: these switches just showed up and I now see why people like the quiet ones for musical applications. These clicky ones have a very nice, positive (and loud) click when depressed and also when released. I won't be using these clicky ones everywhere, just those places I want to be easily able to tell the button was pressed without looking at the button or a light.
Is anyone rocking an alloy case?

I would be in for two sets of panels and cases if there's another group buy.
