Hello all, I'm new here. As I have around 22 unused SIDs and I have some experience with electronics projects I wanted to build a Midibox SID. I hope anyone here is willing to help me with it.
I want to make a stereo sid version with two 6581 sids and full control surface.
What I have ordered so far:
MBHP_CORE:
PIC18F4685-I/P (still have to figure out how to program it)
All resistors, trimmpots, capacitors and diodes and bridge rectifier from my own components bin
BC337 (wasn't sure what to buy, so ordered "BC337/16 TO92", "BC337/25 TO92" and "BC337-40 TO 92")
6n139 optocoupler
sockets
2x MBHP_SID:
4x M74HC595B1R
1x IC78L12 (hmm, still need to order another one for the other sid board)
2x "BC547B TO92" and 2x "BC547C TO92" (again wasn't sure which type to order)
sockets and header
I don't know what to do with Styroflex capacitors, they seem obsolete can't I just replace it with a regular 470 pF ceramic one? I have those..
Bankstick:
24LC256 DIP package
DINX2:
4x 74HC165
I think I'm short on 10k resistors, so I might have to still order those
Control surface:
HD44780 compatible LCD Display 20x2 (I ordered this one)
15 rotary encoders from Voti (SW-ROT-01, this seems to be the same as M-SW-ROT mentioned in the walkthrough, but they don't have those anymore)
110 red leds 5mm
Still have to order some buttons
For the front panel I have access to a laser cutter
As I 'm building a Stereo SID and not a Multi SID solution I guess I don't need the DOUTX1 module? What about the DINX4 and DOUTX4 modules? I'm not adding additional Core and SID modules.. Also I tried etching my own PCBs, but that ended with a sodium persulfate mess and boards with short circuits, I may have to try that again with Iron Chloride. I find it quite hard to figure out what I need to buy with all these midibox versions and revisions and pcb revisions and configurations options and many dead hyperlinks in the instructions/walkthrough/manual. For example the link to forum article about firmware under the title "Resources" on the bottom of this page http://www.ucapps.de/midibox_sid_manual_hw.html
