Oombox

Day 5+ ;)

My stuff on a carboard box has transformed into a fully working midibox. I call it the OOMbox 6581, my nickname is Oomiz. The sound is amazing! I tried feeding it the sidtune Rampert! It's one that pretty much tests every aspect of the sid-chip and I must have won the sid-lottery since my 6581 does exactly what it is supposed to.

Anyway since I've written this thread to get help but also help others I want to give you newcomers a hint when connecting the DINX module. On the PCBs from smashtv, on the 10 header connectors, J3-J6, only the 10th pin is ground. NOT the 9th. This may be obvious for most people but I fooled myself and wasted quite some time figuring out why my buttons didn't work.

About the buttons in my case, they are custom made by me since I couldn't find nice 1cm diameter buttons that are a bit soft but still tactile. I had a large bag of really long (20mm shaft) 6x6mm tactile switches so what I did was that I cut those short. Not something that I recommend, getting them equally long is tedious. Then I wired them up on a perfboard and put a device fot (the soft pads you put under stuff) in every hole of the fronpanel. Since the bottom of the pads are a bit larger than the hole they stay in the holes without actually attaching them with glue or anything to the switch shafts.

The entire thing is built into a pac-tec KEU-10. It's more or less ready and has two banksticks, A0 for patches and A7 for ensembles. All I have to do now is figure out what I need a midibox for, I'm not a musician, but it sure was fun building it. Last step would probably be to paint the case, Oh and I might want to find a prettier encoder knob ;)

Thanks to everyone helping out!

thanks for making it mbotw!

Heh, YOU did that, I just moved the post ;)

Hey I'm curious about the LCD... It looks quite nice, and that combined with the separated 'blocks' for the characters, made me think maybe optrex... but it doesn't have the same backlight.... Maybe an older optrex?

I bought it from a Polish company called artronic on Ebay. Got it supercheap! Only thing with it is that the symbol "|" shows up as "12". It may be possible to change the charset somehow but I haven't looked into it since it really doesn't bother me.

Here is the datasheet: http://www.artronic.pl/o_produkcie.php?id=651?

Thanks mate. Just FYI, you can't change the default charset, it's in ROM - but you can define custom characters. You would need a special driver which then uses the special chars instead of the standard ones. Nothing too tricky, but probably not worth it if it doesnt bother you.

There's no custom chars left in the sid v2 firmware. You could potentially repace one that's rarely used with "|" and just search/replace all occurances of that char in the source code. Shouldn't be too hard, a bit annoying to do but not hard.
