Hi all,
I’ve start a flickr page to log my work in progress on my 4 SID MidiBox.

Looks Very nice so far!!! 
Much better that the crap i´ve put together 
(but I love my crap, and it surely has some personality 
)
Going to try to make i a bit more quality the next time…
Good work!! keep on

Nice PCB for the LED matrix.
Can you post the etch layout here?
Which switches have you used there?
Thanks for you positive feedbacks.
I used switches from Voti for the matrix and Multimec 3F switches elsewhere. I hadn’t bought illuminated ones, I’ve mounted the LED myself because the stuffed one are too much expensive.
I will post the matrix PCB later because I’m not at home. Please note the PCB is double-side and that there is not enought room space to use the pads to connect the wire. So I’ve put the wire close to the LED and switches.

Cool!
Thanks Ludo!

Some new photos were posted and I’m glad to announce that sounds go out from the 4 SID. I found a dead C64 on e-bay and the 6581 sounds like a charm.
But there is a lot of work left…

i’ve seen a printout of the frontpanel on one of your photos. do you want to drill it yourself or will you buy the panel somewhere?
Hi,
As I was really satisfied by Schaeffer Apparatebau works on my SEQ front panel, so I will deal again with them. The print out was made with their software, Front Panel Designer.
Cheers,

One detail, the modules to control Enveloppes + Oscillators, Filters and LFOs.

What are you using for power supply?
Could you put up a close up photo of your power supply ??
Thanks-
looks like he has built his own psu with two transformators and some additional stuff for regulation, to get the needed voltages for the core and sid modules.
You’re right thefRont, it’s a simple PSU. I can put PCB in the forum.
Here is a close-up of the PSU :

Thanks! Would love to the see the PCB layout-
How are you powering this PSU?
I’ll post the PCB layout latter because I’m away from home.
This PSU is powered on 220Vac (Main home power supply).

The Eagle file is here.
It is based on the Core design. Maybe 2200uF cap is a bit too low, but all boards have a 2200uF.

Tonight work on flickr : upgrade Voti’s encoder to non-detented mode..
I really prefer Voti’s encoder to SmashTV ones wich seems to be less precise.

Thanks for sharing mate
Geez I love this place. You guys rock.
