Will do, sir!

Thank you!  This has been one of my more enjoyable projects as of late, and I am extremely glad that a number of people found them useful and of professional quality.

god damn it. next time read the childish scribbles known as my schematic correctly. (meaning use ESP because I didn't put that in the schematic)

I know that I'm bumping an old thread here, but I just fixed the one that I had. I did so extremely sloppily. Melted wire, the works. Works great, just doesn't look so if you open it up.

The reason isn't because I'm poor at soldering or do a sloppy job. I'm usually nice and clean with my work. The reason is that this is a GREATLY made product. It's extremely tight in there and hard to get into to, and I must admit that I kind of feel bad for making an aesthetic mess out of what was honestly a beautifully well-done product. Great job.

Im just glad it was only a wiring issue and not firmware/circuit related

easy fix, although those wires are stiffer than nails

funny you didnt test for it, as for me, that was the first feature i wanted to use (×̯×)

Thanks for letting us know!

don't sweat it man. shipping was fast, thing was beautifully built and at a very honest price.

So far I'm using only MIDI in, but in the near future I'll suck out the solder from the midi-out din and resolder it. Thanks for warning us.

An email has just been sent to all the addresses I have on record.  I strongly urge anyone with an affected unit to attempt to repair it themselves.  If you cannot, contact me so that we can arrange for you to ship it back (at your expense, I'm afraid) so I can repair it.  I will ship it back to you at my expense.

PERFECT.

i'll do this tonight and report back. thank you.

The one on the left depicts the way they were wired.  The one on the right shows how they should be wired.  Just switch the red and green wires on the MIDI out socket and everything will work just fine.  Don't switch the wires at the board, as this will mess with the color coordination (red=positive voltage, black=ground, green=data), but more importantly, unless you have a dedicated desoldering tool, you will not be able to get the wires back into the holes after you remove them.

thanks a lot man!

I did, I just didn't test that particular feature.  I didn't know how to at the time.  Turns out it is as simple as connecting the MIDI in and out on my computer simultaneously to the ArduinoBoy to make sure the same MIDI data comes back.  All future units will be tested in this manner.

Sure thing.  First thing after work tomorrow.

can you post a picture of the arduinoboy with arrows pointing towards the wires i have to switch?

no offense, but didn't you test your units before you shipped them?

good thing I never use midi out on it!!! using MGB right now and its great! thanks scienceguy8!

i did the same thing the first time when i built mine too!
