[mbhp_sid_V3b design changes]

Hello,

I am currently working on a few design changes for a mbhp_sid pcb.

Current changes i made:

-I redraw the Schematic from the scratch to have a .sch and .brd eagle file, this allows easier change in the future.

-The voltage regulator was moved to the border and allows easier mounting on a heatsink.

-An additional connector for direct current supply is optionally available.

-Instead of having ground wires, the whole copper area is now used for ground plane, and therefore better shielding(eventually less noise)

-the clearance between pads,wires,vias and the copper area was changed from 8mil to 16mil, this allows easier soldering(especially for beginners)

-As 4x2 Connectors are not available, i've changed it into a 5x2 Connector, therefore a "Pfostenstecker" can be used to connect to the mbhp_core.Also the distance from the sid chip is a little higher.

So my question is: Have you any other recommendations? Are other people interested in this new version? If yes, where should i put it online?

Best regards,

David

It'd be handier if the DIL header was on the back  :-\

Just sold it at the back like this:

Just dont push the header completely in the PCB and you'll have some place to solder

Keys are from an old Machine Controlling Keyboard. So nice i still have like 50 of them, 10 "blanco"without any label. I am thinking to use them for a Clockbox!

As for the noise, i didnt noticed any difference to a normal power supply.

i guess a little bit noise is unavoidable, maybe you could hear and tell me?

Before building a MidiBOX Sid with whole Control Surface a wanted to build a simple version.

Somebody putted this housing (External ZIP housing)in a trash and i thought its usefull to put the SID inside since it provides 5V and 12V like a Computer Power Supply. The buttons are desoldered from an old keyboard, the encoder sampled from albs, the PIC sampled also. I got the 6581 as donation from a C64 club near, and most of parts were desoldered from old mainboards, connectors also. The cable used inside were also made of old computer cables. I got the LCD for 3 € unfortunately it has no background lightning. Well all in all the costs were around 10€

[Midibox SID + LTC]

i have a sid application running without Controle surface, would it be possible to update the application with an LTC Module? or do i need a with surface to change baudrate or something?

Unforunately my PC is broken and i dont have any midi out on my laptop..

Thanks

con un par de acelerometros se podria jugar a muchas cosas

y con muchos hacer un mando como la wii

With a pair of acceleracion sensors you could do a lot, and with a lot of those sensors do a remote like the wii one  ;D

Thank God my girlfriend is mexican ;D

but he would see the producer in court.

Well thats exactly whats happening for the moment ;)

You might be sceptical but i can hear exactly the same sid sounds out of this song ;)
