seppoman Posted July 13, 2010 Author Report Share Posted July 13, 2010 The high capacitance capacitors might be a little hard to find in ceramic type, I guess foil caps are OK as long as they fit the footprint of the PCB? yes, as I've said before there's not one single cap on this board where the type really matters. So in other words, use what you can get. Also, ceramic isn't better or especially preferable in these regular situations, I've just stated that as a fact that with the regular/cheap/usual cpacitors, the lower (pF...) values are usually ceramic while the higher (100nF and up) are usually foil types. The foil types often come in better tolerances but as tolerance doesn't really matter, both types are fine :) S Quote Link to comment Share on other sites More sharing options...
Altitude Posted July 13, 2010 Report Share Posted July 13, 2010 the Reichelt Styroflex ones are about 10 mm, too. I didn't want to make the PCB larger than necessary so it's a tight fit, but not impossible to mount (see the pic on the Wiki page). Good to know, I had them figured at 8mm diameter. I'll go with the LRC parts anyway since they are very nice 1% tolerance parts and I can get them doestically.. Quote Link to comment Share on other sites More sharing options...

I've just checked the Eagle file and 10 mm will fit but that's quite the maximum. If somebody wants to use these caps, it might be a good idea to use slim IC sockets and/or mount the trimpots slightly tilted (or even solder the SSMs directly without socket). But there'll be a way to do it :) S Quote Link to comment Share on other sites More sharing options...
seppoman Posted July 14, 2010 Author Report Share Posted July 14, 2010 short notice: Joeribl made a public Reichelt shopping cart for the 2164 module, thank you :) although somehow 4 pieces of an 1 MOhm trimpot slipped into this cart. I removed them from the cart and made a new one, so everything's fine now - just in case people have already used this Reichelt cart to prepare an order, please check you're not ordering these 1MOhm trimpots.

Altitude Posted July 20, 2010 Report Share Posted July 20, 2010 Oop. one more question, for the SDCARD, what is the distance between centers of the mounting holes in the PCB? Quote Link to comment Share on other sites More sharing options...

Altitude Posted July 22, 2010 Report Share Posted July 22, 2010 For the US/UK crowd More on those British LRC 10 nF Polystyrene (aka sytroflex) caps: http://www.newark.com/lcr-components/fscex-10000pf-1-63v/capacitor-polystyrene-0-01uf-63v/dp/97K0250 Size wise they are thinner (5mm diameter vs 10mm) than the xicon so they will fit perfect width wise. They are also 1% vs 5%. These are available at Newark (US) and Farnell (UK) Quote Link to comment Share on other sites More sharing options...
Jack Posted July 23, 2010 Report Share Posted July 23, 2010 Hi seppoman, Do you have a update of the delivery progress? Best Regards Jack Quote Link to comment Share on other sites More sharing options...
seppoman Posted July 24, 2010 Author Report Share Posted July 24, 2010 Uhm yes, update, better :whistle: I've been away for one week and since then there has been a very busy phase including spontaneous business trips etc... so I'm sorry to say the last few shipments haven't been posted yet. But yesterday I've finally managed to prepare these last shipments and I'm going to post them either today or on monday, so the waiting should be over soon :) to all others, if you have ordered only a few PCBs and still didn't receive anything, please PM me and we'll try to find out if something went wrong. The "small orders" all have been posted weeks ago. S Quote Link to comment Share on other sites More sharing options...

Antix Posted July 26, 2010 Report Share Posted July 26, 2010 Hi, Anyone knows why the styroflex ( polistirene ) cap haz a stripe on side? Normally ( what is normality in this world? ) a sidestripe on a el-part may indicates polarity. Regards Antix Quote Link to comment Share on other sites More sharing options...
seppoman Posted July 26, 2010 Author Report Share Posted July 26, 2010 oh come on guys, I've explained what a "big order" is some posts ago :yes: Anyway to end the questions, I've posted the remaining shipments this morning and here's a list of these people (i.e. all others should hopefully already have received their PCBs by now): rosch grizz modularkomplex fuzzylizard Wilba Jack Antix bugfight (benuron, reposted because of changed adress) Again, I'm really sorry that this bulk order took at least 1-2 months longer than necessary, but there are periods in life where Midiboxing has to stand back a bit behind other more important things (if I had known a few things beforehand that would happen, I'd probably have postponed the whole bulk order by a few months). But finally all orders are out now and soon everything's gonna be fine :hug: Happy soldering, Seppo Quote Link to comment Share on other sites More sharing options...
Altitude Posted July 27, 2010 Report Share Posted July 27, 2010 If anyone is interested, I did up a FPE file for the SDcard PCB. I used these mounting brackets: http://www.mouser.com/ProductDetail/Keystone-Electronics/616/?qs=TMDrOSIpnUcl1d%2fTSUe7rw%3d%3d but you may want to adjust the height to whichever you wish to use. Either way, the slot is about 0.5mm to the left of center looking into it for it to center on the card.. http://midiot.net/MB_SDCARD_Slot.fpd Quote Link to comment Share on other sites More sharing options...
