Its the midi controller I designed still need to order the solder and put it together.

Going to write the firmware to test the board now.
 
Have to agree, that custom PCB looks amazing.
What kind of I/O is there?
 
Its a usb 2.0 MIDI controller. (should be usb 2.0 compliant but as of yet is untested)

Features:
2/3 buttons depending on firmware settings.
USB bootloader for standalone programming / firmware updates
SPI micro sd card reader (fat32)
2 main faders (one for each channel)
One cross fader
6 nobs hi mid low trims x 2

It is a mixer designed to be ultra compact and portable for Virtual DJ , the two buttons are for syncing the beats within the program but this is compatable with any thing that accepts midi input.

The micro sd reader is composited into the midi controller firmware , that way you can goto a friends house with only the mixer and have your music and virtual dj or other software IN the mixer ( kinda an onboard harddrive)
 
that sounds great, i get a FREE prototype ofcourse right :)

lol, na, ill pay for one though :)
 
Nice yeah im working on the first draft of the firmware now. Then me and a beta tester are gonna see about getting it mac compatible thus far i have not been able to verify that it is working with mac , atleast not with out a driver. Supposedly it should be.

Yeah im thinking the finished product should be right around 100 $ , but currently the board is costing me 5 times what it should, due to quanity.
 
I got impatent and hand solderd one, with out the micro sd , its working it seems.

The faders are ultra expensive hence only one on this board

its a usb 2.0 midi mixer. Why to store musics was the idea. but not sure if thats gonna work or not

havent gotten to writing the code yet for that part.

So far i got the bootloader working , and 1 button was working on coding the fader at the bottom when i passed out.

This thing actually has 3 full firmwares.
The bootloader
The midi firmware
The msd firmware for the sd card

Im around step 2

Once I saw it was working I lightly tacked on the other faders (really really lightly solderd just the 3 connection pins

Yeah , still working on the firmware though,

So far i have the pots working, the power system, 2 of 3 buttons, trying to work the bugs out . About to leave for work but shortly here I will make a little video of it working etc.
 
looks nice, cant wait for the vid.

one question, why 3 separate firmwares? Are u tribooting or are they for separate functions?
 
1. Bootloader (allows firmware updates after the device is sold)
2. Usb Audio device , subclass MIDI
3. Microsd reader (i still havent figured out if this part is going to work.


2 and 3 will be active during normal operation.
1 will only be active when your upgrading to enter there is a hardware key much like the psp service mode.

Ok a video.....
yes the cross fader is backwards , its one line of code to flip it , just forgot to do it.

That's awesome, nice work man :)
 
Thanks man!

This would have been an entry for the Make.com halloween contest but after reading the rules I realized that idea conflicted with me releasing the pics / info here first, All my releases will always be posted here first.

If any one from Make sees this feel free to post this. It would make my day no pun intended.
