Hello all,

I've split the DIY Minipops Clone thread into Minip7 and MP7.
One another to avoid missunderstandings.

This thread will hanlde MiniP7 which is the Clone of the origonal.

Rendered and Frontpanel that arrived today.


All information of this project can be found at:
viewtopic.php?t=194996
Here you can find the whole development process, soundfiles, PCB renders etc.

In attachment to this post one can find the order form for the MiniP7.

The panel looks nice!

[Boogie]

Hello all,

Just to let you know,
The order opportunity for the MiniP7 ends today in week.

NANO-Jorge The panel looks nice!

thanks.

Hello all,

today is the last day I will be accepting orders for the MiniP7.

Hello all,

no more orders accepted for now.

B rgds,
Boogie.

Hello all,

PCBs and Components for the first production run are ordered.
To make sure everything fits with the mechanics,
I'll order the Fronpanels when the populated PCBs arrive.

Pls allow 5-6 weeks for the PCBs to arrive, according to the initial time frame below.

Planning outline.

Put prices online cw13 Done
Ordering till end cw15 Done
Order materials and populated PCBs end cw15 Done 3 days delay compared to initial planning.
SMD population (subcontractor needs about 5-6 weeks) cw21
Testing a couple boards cw21-22
Transporting the kits cw22-23

Hi Boogie,

I was some time off, bit is it still possible to order the MiniP7 ?
It really would to be a fantastic add-on to my synth collection.



And sorry for asking, but is there any chance to add a (3rd party) basic Midi-interface (as the Mini-implant) on your MiniP7?

Thanks.

[Boogie]

Fitchie

You're a bit late, but oh so lucky !!

I ordered 5 more (populated PCB's only, the rest you'll have to order yourself)
Of those 5, I have 3 left.
If you download and fill in the above OrderSheet_MiniP7_V3.pdf
I can tell you which serial nr you'll receive.

In case you insist on having midi,
I suggest to wait with your order till the completion and availability of the MP7
Pls visit the MP7 thread here: https//www.muffwiggler.com/forum/viewtopic.php?t=199361

Thanks

The TH components for the MiniP7 have arrived

[Boogie]

Hello all,

I've just been informed that the production run of the PCBs wil probably happen this week which would mean that they arrive 1 week early. (cw20)

where can this information be found?

Original thread before splitting into MiniP7 and MP7
3th post on this page:
viewtopic.php?t=194996&postdays=0&posto ... &start=250

if you still want to order, pls use the latest format published in this thread in the first or third post.
TH components can not be ordered, from me, anymore as the kits have been made.
A couple SMD populated PCBs are still available,
As I will only order the FPs after a first mechnical fit on the final boards, I can still expand my order of frontpanels.
So SMD populated PCB and FP can still be ordered.

[Boogie]

SMD populated PCBs have arrived

I will further update about debugging and assembly over the next couple weeks .
As soon as the first one fits my FP mechanically, I'll order the rest of FPs.

planning wise

Running from the first time !

I assembled one PCB this afternoon and powered it up.
After programming the processor, it ran from the first time.

I have to check on a couple values of resistors as the volume balancing might need some small updates (change the value of a resistor)
Apart from that, it's all looking very good.
Mechanics fit perfect.
Some pictures below.
At this tempo, debug should not take a couple weeks.

[Dr Gris]

Great news!!!

I guess it's time for me to start thinking about enclosure and power options.
I'll be bringing it with me to live gigs as a standalone unit

[Fitchie]

Impressive !!!

[Boogie]

Since the V2.01 has quite an updated schematic compared to the V1.01,
I had to redimension a couple values.
No trace cuts or additional wires.

Audio demo already recorded but still to be put in video format.
That's for later tonight or tomorrow.

[NANO-Jorge]

It looks superb! What microcontroller IC are you using? Just being curious

[Boogie]

NANO-Jorge

What microcontroller IC are you using? Just being curious

It's a dsPic33FJ256GP710a, way too big for the application, but the standard I use for most of my projects.

[Boogie]

And here's a first audio demo of the first MiniP7_V2.01.
You may find some slight overdrive from 30 to about 40 sec.

Below a movie in which two MiniP7 are synchronised by means of a synchro signal and external clock.
All remarks/questions welcome.

Hello all,

Front panels have arrived,
and...
they fit

I will complete the kits and send out the requests for payment during the coming days.
