MIDIbox SID-NUXX
It works. Makes noises, menus work, etc.
It works. All of it. Everything on the board. Except for one little snag (one part label is printed backwards) the whole thing works as designed.
The input buttons, the LCD, the MIDI LEDs, the memory, all of it.
The voltage regulators run a bit hot (~150ºF when the LCD is connected) when using the 12V SID. Using a 9V one instead should make things a bit better. I don’t like this, but there’s really no easy solution short of using an external switching power supply and redesigning the board. Which I’m not going to do. It’s well within tolerances, though.
I think that next I’ll build a board to handle the 9V SIDs, then I’ll have two complete boards for myself. Then I’ll build either one or two enclosures. I’m also tempted to shove one into someplace interesting… Like a MIDI keyboard. :D
Sweet!
The LCD doesn’t look much like the product photo. Need to fix that tomorrow… Then design the enclosure. :D
awesome! congrats!
Weeeee!
Gimme. :D
I said this last night; i’ll say it again… nice job!
It’s very cool that you got it working without any jumpers, etc… especially since you had to re-start the circuit layout from scratch…
Can you hear the midi noise (or cpu noise) on the audio output?
No noise at all as far as I’ve been able to hear. I think I did a good job isolating it. I’ll have recordings up later, and I’ll be able to hear lots more once I hook it to good audio.
The only noise I hear is the typical SID bug of being able to hear the VCF until a RST is sent.
