i'm interested in buying a pre-made arduinoboy circuit.... any in stock and where can i buy? email me with info pocket.soup@yahoo.ca

Should do, as long as the arduinoboy has its own power supply from somewhere.

yup i snagged one up!

argh, the webpage still says "2 units left", but apparently these are already sold
I pray I'll notice in time when the last batch is ready for sale...

Btw, anyone tried the arduinoboy with Nanoloop 2.3 (on GBA SP)?

I've had my eye on one of these for a while now too, gathering up all those parts is just too much of a hassle. Would these still work with one of the 4-pin DMG link cables? I know some midi interfaces use a 5th pin for power

i would be happy to make arduinoboys when scienceguy stops

blargh!

I neeed one of these. The second I can afford it, I'll buy one, I just hope you have some left.

it would be so great to offset mgb's midi.

What... the.. ???

I was JUST now looking at these and considering the purchase of one.

Just a reminder that I have 2 ArduinoBoys just lounging about ready to find a new home.  I think I may be close to saturating the market, so after I finish these final 15 I think I may be done.  It's time to be looking at a new project.

As usual, you can find them here: http://sites.google.com/site/gilbertiin … arduinoboy

please and thank you using two gameboys at the same time is quite jittery (very glad you modded the code /me bows)

i suppose if the bug cant be fixed with MGB, it could possibly be done at the arduino side? either an arduinomega with multiple serial ports sending different channels down different gameboy cables (maybe you don't even need the extra serial ports) or multiple arduinos sharing the same midi input?

MIDI was designed for multi-channel communication. As you may or may not know, there are 16 MIDI channels you can use, that can be transmitted over a shared line. The mGB mode in Arduinoboy just translates MIDI data into the serial port format the Gameboy is using. It doesn't alter the data. (Well ok, it does do some editing, like erasing some duplicate messages, but that's not relevant here.) It does forward data for all channels. So in theory it's possible to just connect several Gameboys to a single Arduinoboy output with eg a spliced cable. I also modded mGB so it could receive MIDI on other channels, 1-5, 6-10, or 11-15. That worked relatively ok, but as it turns out, mGB doesn't handle data sent on other channels than its own channel. So if you send data on channel 2, when mGB is receiving on 6-10, it might freak out and crash. If someone (me?) can fix that bug, this method will work.

hmmm it might be possible. not with just a standard midi gameboy and link cable, but it depends if the arduino just sends note data to the gameboy or if it expects something back from the gameboy.

if it just sends data you could again link as many gameboys as you want to MGB and play two different tones with the gameboys together, maybe cords

unless you are talking about pocket gameboys. if you mean you want to sync two pocket gameboys to midi with one arduinoboy, that would also be possible except the pockets don't seem to have enough power to drive the arduino so you would need an external power supply i think.

but as for doing things like having multiple midi thru sockets on an arduinoboy, and multiple link cables on an arduinoboy i have actually already made these for people and they seem to work so far, apart from multiple link cables need to have a master and slave link cables.

one other thing that might be possible, by editing the arduino code a little bit, you could have different channels going to different gameboys allowing maybe for cords using 3 gameboys? or maybe seperating the note data, i needs more investigation.

what about two Mgbs? I already figure this is not possible.
