Wallwart PSU from Amazon US

I found this pretty cheap wallwart on Amazon.com and looks like to be a good candidate and another source for a PSU. I intend to use this with my 6582 sammich.

* Fully Regulated 100V-240V can be used world wide
* 12V DC 500MA Switching Power Supply
* 6 Ft Long cord with center positive 2.1 MM jack

All the switchmode power supplies I've tried put noise on the audio outputs. They are not recommended (as I've stated in the build guide).

is it possible to add (hack) extra midibox sid appendages onto the Sammich? Extra sid boards, cv outputs etc?
or would be just as easy to start a fresh project?

Extra SID boards: MIDIbox SID is arranged as one Core8 module (PIC) for one or two SID modules. sammichSID is just one Core8 module and one "stereo" SID module, integrated onto one PCB, with connections to a separate control surface PCB which contains DIN and DOUT modules for switches, encoder and LEDs. So extra SIDs is only possible by connecting the sammichSID base to another Core8/SID module. (In theory, you could also connect to another sammichSID base PCB). So technically it's possible, but you would have to design a new case to fit it all in... and then also deal with there not being any SID 1, SID 2, etc. buttons on the control surface, so no (nice) way of controlling the other SID engines.

Similarly, anything you can do with a MIDIbox SID (like connect to an AOUT_NG module i.e. CV outputs to filters, connect to analog inputs i.e. joysticks, pots) is possible, all the ports are there to do it, but you'd have to work out how to enclose it all. It's obviously not designed for extra stuff added inside the case.

To answer your last question, it would be easier to get an MB-6582 base PCB and use that as a base for something more custom, or to have more SID modules. MB-6582 contains four Core8/stereo SID modules on it, but you don't have to use them all, and is certainly a lot easier to scale that down than scale sammichSID base PCB up.

Me likey Mebbe with white button caps it would be even moar purrtier? Oh and with a black on White display

Ha. I guess I probably should have realized switching/switchmode were one in the same. Should've figured there would be something wrong with this. :-p


Hopefully I can redeem myself with this :

It's the last model on this pdf :
Linear PSU Model : ST-1212-R0.5A

And here it is on Amazon for $11.95 US after shipping

You can has redemption. That one would be perfect for sammichSID, even when using 6581 SIDs, which require regulated 12V tip positive. However, regulated is better for 6582/8580 also... input voltage will be constant and just enough, keeping heatsink temperature dissipation to a minimum.

If you buy it and test it, then I can recommend it and you can haz moar redemption. Or a free frogurt!

cheers for such a detailed answer
think a sammich would be enough to keep my green hands full for now but it's good to know the possibilities are there.
am on the waiting list for a sammich, might well try something a bit more ambitious once that comes together...

That white one looks B.A. Baracus! Gimme!

Will that white be available in any future batches? That's hot.

YES. Ponoko could not get enough matte black acrylic for the last batch, so I got some made out of Arctic Ice for the people who preferred it. So I will be offering this in the future.

I have finished my sammich and am wondering if I should buy a 1x stereo TRS to 2x mono L/R 1/4" cable to get stereo effects going. I keep reading about "stereo sid" and I can't seem to find any info if the audio out jack is actually in stereo. Is the audio in stereo too? Just don't want to buy a cable I don't need if its mono out.

[nILS]

Both the input and the output are stereo.

Great Success!!
I've just completed my sammich and have been noodling away for hours since. Thanks to wilba, nils and team for putting together the best DIY electronics project i've ever encountered. The design, scope and quality of your sammich puts most of the commercial 'equivalents' (ie, DIY projects of similar size / price) to shame (imho).
As a result, i will definately be undertaking more midibox projects in the future, the sammich is the perfect stepping stone towards some of the more intimidating projects in the lineup.
Glad my first post here could be praise as opposed to troubleshooting questions! once again, a testament to the instructions!
thanks again guys,

matt.

Woot! I get beer and didn't even need to do troubleshooting!

yep, nice work, enjoy!

Hi,

I'm considering getting on the preorder list, but I have a few questions.

How are patches created for this? I haven't been able to really find an editor or vst. Then, how are they uploaded to the hardware?

Also, can you sequence 6 tracks at a time, since there are 3 for each sid, or are you limited to 1 or two at a time?

Thanks!

You can edit patches using the control surface. Read the manual: http://www.ucapps.de...sid_manual.html

There is a patch editor (Java-based) and also a VST patch editor/controller for MIDIbox SID.

Using the Multi engine, you could setup six single-oscillator instruments, each on its own MIDI channel... or configure it as multiple polyphonic instruments. The Lead engine is one voice but stereo, using both SIDs (6 oscillators).

Hi,

Is still a batch of kit available ?

Many thanks in advance..
