[CEM3379 Stereo VCF assembled board]

Hi, Peter! Saw your 2 hour MIDIbox SEQ building tutorial at Youtube, great work!!

[CEM3379 Stereo VCF assembled board]

@Antichambre This an old project, but I'm still not finished the control surface. Enclosure has taken from old soviet "MICRO" calculator Elektronika MK-44 but it has no main PCB, so I'm still searching for another one to take keyboard from it for more authentic look 
Rio asked me for the project files, so I've uploaded everything to public. 
Yes, design is based on Olivier's original Shruthi-1 CEM filter board, other parts is quite standard except OLED - CORE8 PCB with MidiboxSID v2.042, Stereo SID6581 PCB and AOUT_NG. PSU is taken from old DVD player - +5/+12/-12 volts, CEM VCF powered with +12/-12V.

The only one noisy part is OLED's boost converter, I was thinking of powering it directly from +12V rail, should fix the problem.

[MBSeq TPD module]

What connections do you mean?

It's only connected with previous module in SR chain (Wilba's CS in my case) via standard 10-pin cable.

[MBSeq TPD module]

Using forum attachment was bad idea. Now link should be ok.

[MBSeq TPD module]

This is for LPC17 core, TPD connected to Wilba's CS out. 4.079 firmware + hardware config.

Case template for both transparent and opaque material.

/edit TK: note that this .zip file doesn't contain the final V4.079 project.hex and MBSEQ_HW.V4 files!

The latest release can be found under http://www.ucapps.de/mios32_download.html

The adapted setup file in the midibox_seq_v4 release package under hwcfg/wilba_tpd/MBSEQ_HW.V4

6581`s with VCF/VCA sounds fantastic!!

[ButtonLed Matrix]

Yeah man! That's real perfoboard hardcore!

[SammichFM perfoboard CS]

why you have the base, but not the control surface PCB

That was a sale. I was buying OPL chipset from Wilba and he offered me base pcb for $10 =) At the time I did not plan to build another MBFM but now there`s no free space left at my deck so i`ve replaced large MBFM with Sammich. :rolleyes:

kHz-tone, knob or switch caps?

The knob is from old soviet lab equipment and the caps are from Rosch, standard sammich ones i think.

[MBHP_stereoSID_v01_PCB]

No, it`s for home-etching. With 2 layers it will be more compact =)

[SwinSID test stand]

You've prompted me to do it =)

[CS back]

I can`t find good vero analog here, which enamel will melt with solder tip temp. I`m using Russian ПЭТВ-2 enamel wire, which is very strons, so tinning is real pain.

Solid wire is for ground and leads... Why i have to cut them if i can use it =)

[MB_StereoMicroSwinSID prototype]

There is no schematic for sammichSID so i have to redraw it from PCB file which is also have incomplete info. I was able to do it only with help of of fnpSID PCB and photos of its backside.

[Technodistortionsgerät]

Will it work with single polarity supply?

[Technodistortionsgerät]

Thanks! I tried to make a few more simple circuits but was not satisfied with the result. This is what i need! =)

[Technodistortionsgerät]

Beware of soviet diodes! :nuke:

[Technodistortionsgerät]

Very nice!

Which design of germanium distortion did you use? Can you share schematic?

[midibox fm strange characters]

rosch, it`s acrylic laser cut, inspired by Shruthi`s case.

[midibox fm strange characters]

No, TK`s MBFM.

Waiting for Wilba`s package to make it 4-channel.

[Watch your bass-bins!]

Cool! Black/Orange combination is good.

And it looks very professional!

[SMD boards]

Eagle files if someone wants to modify it.

[SMD boards]

Confirm that DIN module is working, DOUT seems to work too.

[SMD boards]

DIN PCB positive

i have forgot that not everyone has the Illustrator :rolleyes:
