lucem

Well, I don't think I'll change my mind. Things I rarely use usually stay that way... sadly enough. The 450 is the absolute minimum, I wouldn't go below that. But on the other hand I know that that's already a lot of money, that I can't really ask much more, and that I don't want to make a profit from the sale, I'd rather take a small loss in respect to what it cost me. The difference is made up by the fun I had with it ;) Sure it's sad to let it go, I've spent a lot of time building this thing (and other midibox projects), so there's a lot of me in it. But I'd rather see someone put it to use than it to gather dust

As promised, here come some picture of the box Two shots of the inside (old pictures, still valid) And now for the outside (freshly taken) Since the display is not to be seen active in these pictures, it's yellow on black (that's what it's sold as - looks a tad bit greenish in reality, but not as green as the standard displays).

Their facebook page Happy spamming :)

After I realized I did not use my MBSID for a long time, and the wish to renew my keyboard rig for my band work, I've decided I'd sell it and make someone happy who will use it. It's a fully built and functional unit in MB6582 format (meaning PacTec case, MB6582 mainboard,front panel etc). It's got six SID chips mounted inside, in pairs of 6581, 8580 and 6582 with the corresponding filter capacitors mounted. I always wanted to use the remaining two slots for SwinSID modules to have and emulated SID in there as well, but I never got around to that (oh, the long build queue...). I didn't see the need to mount a fan, so it's completely quiet; if one needs the feedback potentiometers mounted, he can quickly do that himself, as I mounted connectors for those (the corresponding cables can come along with the box when asked). I've paid more than 500 € in parts for it, so the minimum offer should not go below 450 €. This is not to make a profit on it, but I don't want to lose a lot of money in it either. I'd prefer to limit this sale to Europe, Germany would be even less painful (shipping with the Deutsche Post _is_ painful). I don't have any picture right now to add to this post, but I will add them later, they still need to be uploaded. I should have pictures online tomorrow. Since the last set of photos, I had exchanged the front panel and knobs, so I think you'd want to see how it looks like now instead of a couple years ago. pm me if you're interested; I'm not so much around on the forums as I used to be, but I still receive pms by mail, so this is the quickest way to reach me. Oh, I haven't mentioned yet, of course the original C64 wedge PSU will come with it (for 230V/50Hz). Okay, thanks so far, I'll see if there'll be messages :)

W, if you need pictures, just say so... You can haz beautiful shots of the guts if you need 'em.

Resistor networks are correctly oriented all the way.

W, just what I described in the post, the resonance encoder decreases value when turned clockwise. But I don't really mind, since a rather simple change in the code can fix that... It is positively the very same encoder as all others, and it is the only one showing that kind of behaviour. The connections between mainboard and cs board are all 1:1, I did not accidentally solder the wrong wires in the wrong place. Due to that, I initially concluded that this is the intended behaviour for that specific knob.

Mine shows the same behaviour... from my perspective this is the correct and intended way it should work though. If you don't like it that way, you can reverse the encoder behaviour in the source code setup and re-compile the application.

No, it's flexible wire, so the stress is much less a problem than with solid wire. I soldered the connectors to the mainboard and the wires to the CS - but there's no reason it shouldn't work the other way round.

No problem. I soldered them directly to the board, since 30cm is really enough to open it and leave it connected :)

Yeah, they come ready to use, one end open tinned wire, the other one crimped to the connector. The board connector comes with it, too. I used these to connect the LCD, too - fits nicely on single row displays, for double row displays usual IDF connectors are preferrable.

I used these connectors for a reliable and removable connection between the two boards: http://www.reichelt.de/?;ACTION=3;LA=2;GROUP=C1442;GROUPID=3224;ARTICLE=32346;START=0;SORT=artnr;OFFSET=16;SID=32mZJE3awQASAAAHg@5Ood0868d254968150e47f106737357f08f These here might actually work even better, as the straight option is pretty tight when the case is closed: http://www.reichelt.de/?;ACTION=3;LA=2;GROUP=C1442;GROUPID=3224;ARTICLE=14832;START=0;SORT=artnr;OFFSET=16;SID=32mZJE3awQASAAAHg@5Ood0868d254968150e47f106737357f08f The latter ones are angled 90°, and should provide enough comfort for cabling :) There are also connectors with less pin count available, suitable for MIDI socket connection, power supply etc. If you do not reside in .de, I'm quite sure you can get similar or the same stuff in other countries as well.

it won't hurt that they're populated, just don't connect the I2C IN ports when soldering on the receptables :)

Using a sifferenz size LCD is just a matter of changing a couple of lines in the code.

Hehe, at least you got that one ;) Keep it on, you're famous now ;)

This is insanely great.

Heya, I was just a bit baffled when I was trying to post a new blog post... didn't someone tell the midibox forum software that 2009 isn't the last year ever? We already are in 2010, aren't we? So I thought I'd better report that here ;)

The LEDs are 3mm tight fit. For the buttons it's slightly larger, iirc 3.5mm. The drills are optimized for Omron-style buttons. I'm guessing two scenarios now: a) you're going to drill the panel yourself and want to know what drills to use (in that case, just measure the thickness of the button shaft and a little bit to ensure they don't get stuck) b) you're searching for fitting parts to stuff into a ready panel (in that case, 3mm LEDs and Omron buttons with 13mm shaft length or 15mm shaft length are the way to go)

Actually, if you have free pins left on the core32, you can use more than just two ;)

Try looking on Apple's developer pages, the CoreAudio API documentation plus examples are in there. If you already have XCode and the CoreAudio SDK installed, there should be tons of examples in the Library folder on your Mac, too.

Looks great man!

I have such a kind of setup for 2+ years now, and it works absolutely reliable.

Sry, was ist eine "normale" Midibox? Eine Tastaturscanmatrix and die CV dranzubasteln müsste machbar sein, allerdings wäre es auch eine Möglichkeit, einen zusätzlichen Core zu verwenden und den die Tastatur übernehmen zu lassen - Codebeispiele dafür sind im Forum vorhanden...

Why don't you write it yourself?

That's about it, yes... Such an application could be built on top of the MB64 codebase, and would probably require not too much effort.
