Hi guys, this is my first post on this forum. Recently i have been working on a project: it's an LSDJ/Nanoloop music workstation with buit in DSP Fx and amp.
This is by no means a tutorial, it is the first prodotype and when i build the second module i will be compiling a full step by step tutuorial on how to build one
The Idea...
So i was rumaging through some junk i have laying around and unearthed a GBA SP, an old broken NES and an Alesis PicoVerb FX processor. I began thinking on how i could combine all this stuff into something cool. I decided on an 8BIT MPC (sort of)
This is the idea taking shape:
I began with fabricating the GBA screen into the console using aircraft grade bodyfiller and then got my father to paint it at his place of work.
I then decided to use arcade buttons to controll the GBA. 6 in total to controll up, down, left, right, A and B
After installing the arcade buttons i was still left with Start, Select and the R/L bumpers without controll so i got 4 small square buttons for these that match the arcade buttons nicely.
I removed the origional stereo pots of the PicoVerb with 4 mono pots witch utilize the PicoVerb as a primitive 2 channel mixer.
I decided to use the cartride slot for a little patch bay (one switch isnt installed) This patchbay allows you to process the gameboy through the picoverb or an external source and alow you to patch either the GBA or the picovers (or both) to the built in amp and speaker i have yet to install.
I then mounted the bottom half of the gameboy. I decided to mount it here so swaping cartridges is easy and quick. The 1/4" jacks on the back are the stereo ins and outs of the picorverb and the RCA outs are strait from the gameboy.
Power was a bit of a problem. I need 3 voltages. 5.2V DC for the GBA, 9V AC for the PicoVerb and 12V DC for the lights in the arcade buttons and the amp. I decided to dismanltle the 3 power supplies and install them in a gutted Xbox power brick. This will conect to the console using a DIN plug suppliying all 3 voltages neetly.
That's all for now, i'll keep you guys updated with the build.
I'll leave you with some more pics and a video of testing the device:
