The SD Card holder is article 571-2041021-1 at Mouser. It’s A101492CT-ND at Digi-Key.

group order time now, huh? digi-key and mouser. i think this time i make it stock so i can use Frank’s case, the other approach lead me to not finishing anything (yet). i guess we better start a new thread for that

Which parts are EU unobtaniums? :)

The exact SD-card holders, the knobs if you really want the originals (maybe*), the button caps used to be for the old Shruthi – the Ambika seems to have the same as the xoxbox so we have a few more options and the pots – ish. Also, the Audio-grade electrolythics are tricky.

*Some items at Farnell are located in the US and you’ll have to pay a sizeable extra per order in Europe. Also, Farnell only sells to companies. The SD-card connector is a US thing.

Seriously, I could! The issue is that Sweden has a 25% VAT. I’m sure we could shave off some money by ordering to a less tax-the very fabric of reality™ county. Just saying :)

Also, some things are wonky like the Reichelt Styroflex caps. Maybe those could be bought in bulk as we could all find resistors and what not both here and there…

@fcd72 that might be handy. That would keep me going for a lonnnng time, I think! Actually, thinking about it, I have a UK source for most of the ceramic caps now. I just have to buy a load of them at a time to make it worth it, as the delivery is quite expensive (compared to the cost of the components, anyway).

Mouser UK parts come to £64.55 excl.VAT and duty. That’s for everything though, including Atmega and 2x40 LCD.
Several items are currently on backorder:

0.1uF ceramic caps (75-1C10Z5U104M050B)
MIDI sockets (161-0504-E)
Male 1x6 pin headers (649-77311-118-06LF)
Tact switches (612-TL1100)
2x40 LCD (763-NHD-0240AZ-FLYBW)

The caps are a pain, because there are 21 of the f*ckers. That’ll be £4.95 delivery from Rapid for those. These ones should be OK, shouldn’t they?

• MIDI sockets: Rapid again, but they’re on 1-2 weeks backorder.
• Headers: not a problem. I find it’s cheapest to get those in long strips from eBay and cut/snap off what you need.
• Tact switches: Rapid again.
• LCD: I’ll probably get one from pichenettes, so not a problem.

I’m going to hold off on the order until pichenettes has posted the BOMs for the voice boards, too. No point in doing multiple orders.

the audio sockets were pretty much unobtainium here too if i remember correctly. i can get Farnell stuff here but as toneburst has mentioned, if it’s stocked only in the US it’s much more expensive (and the people i get them from are a pain sometimes)

@pichenettes Great work on the main board walkthrough, by the way. I’m always impressed by the high standard of your documentation, and this is no exception!

@pichenettes Cool, good to know. The voice cards look relatively easy to construct. I’m sure all of us future ‘pioneers’ would be able to do those without a walkthrough ;)

No, these could work on a Shruthi ; but because there is a narrow row of 6 jacks on Ambika I had to select the slimmest ones.

> Also, Farnell only sells to companies.

Maybe they used to do that? Im merely a private individual and have had no problems placing orders with them here in the UK.
Well, Apart from the parts they have to get in from the US (usually caps) and then they charge you extra for. By which time you might as well have gone with Mouser or Digikey to start with.

@Luap: Cool if they changed that! Guess I’ll give them a new shot instead of giving up. I didn’t want to invoke my dad’s company or the rather large corporation where I work due to fears of getting harassed by some sales people :)

Well back to the normal comings and goings…

@rosch is that PCB Mike of Mike’s MIDIShop fame?

afaik, farnell don’t sell to consumers in germany – only to businesses or students. consumers in germany can order farnell stuff from hbe-shop.de.

Freaking cool! I love Mutable Instruments black PCBs man… They just make me want to build!

Has anyone worked out where we are at cost-wise for a 6-voice fully-populated Ambi? Is ballpark USD $800 near enough or a little short?

I definitely have some money saving to do before this is happening. Or find something to sell :-\

No this is not the right part, it needs to have long legs so that the voicecards can be stacked on top of each other. It’s the same part as found on the Arduino shields.

sorry to be redundant, but does it look like this one: http://www.robotgear.com.au/Product.aspx/Details/349 ?

Oops, just bought the wrong ones…
Thanks for the heads-up, pichenettes.

Ok, then here would be the Mouser part?

Voicecards BOMs!

Hmmm… I wonder. So are these filter boards “stripped-down” version of the Shruthi-1 filter boards? Can I be safe in assuming they are comparable? Thing is I’ve yet to build any of the newer boards so if I could make a comparison it would only be to the smr-4 mk1. How to choose? I guess getting one of each would be the way to go…. hmmm. Would a character chart or a little low down on the timbre of the different voices be too much to ask?

@KSD: My understanding:
SMR4 is a stripped down version of Shruthi SMR4 MkII with thinner resonance sound due to using darlington buffers (but OK for poly use)
4P is the 4PM core but restricted to a single filter mode (4 Pole Lowpass)
SVF is half of the dual SVF board (single filter only but still multmode)

@So given that those part have been stripped out it would seem as if the options would be like a treecko, a bulbasaur and a shroomish (all grass type) as opposed to a scyther, a wingull and a mew (bug, water and psychic respectively)@

Wait… what? :)

Just did a Mouser project for the 4P board components.

• The poly caps (649-77311-118-06LF) are on backorder
• The orange LED (604-WP7104LYD) isn’t stocked anymore, apparently.

Comes to £15.45 excl. taxes. That’s €19.33 or US$24.02 at today’s exchange-rate.
Not bad! That includes the Atmega, incidentally.

Does anyone know if it’s possible to combine several Mouser projects into a single order, without having to manually copy items from one list to another?
