xiwi am I correct in assuming the color choices on the arduinoboys is the LED color?  I went with blue and I'm just making sure that it's the color of the LED's and not the unit itself.

Yep. Color choice is the LED. All enclosures are white acrylic.
Updating my page info now. So much stuff to update!

SuperBusty I must have lost your email. Some times I get all panicky about clearing my inbox and might have archived yours by accident. Let me know what's up. So sorry about that!

Thanks for the input herr. Any chance you could share you experiences with me/us? It's really helpful for me to understand what happens to my devices after they leave me shop.

When are you gonna get some more arduinoboy kits in stock?

As soon as I sell these 6, I'm going to order a batch of 10 PCBs for kits. At the very latest, mid January. I want hold to off until I get a sense of how people respond to the open enclosure style.

Here's a link to the eagle file and the gerber docs. You can send it to a place like OSH park and get a batch of 3 printed for like $30.

CORRECTION:
The resistor marked 270 below the 6N138 and between the two 220 resistors is ACTUALLY 4.7k

wait, will this work on a gameboy advance running nanoloop 2.x? i don't know how arduinoboys work :s

I tested a while back with Nanoloop with success. Let me recheck and I'll get back to you later tonight.

For Nanoloop, the Arduinoboy receives a MIDI clock signal and syncs to it. You can't send MIDI Note data to Nanoloop or have it send a clock to sync other devices.

Completed Arduinoboys are now back in stock. New version. Batch of 6.

Kits will be available by the end of the year.

Thoughts on the open case design are invited.

I love your LED placement and the button. Keeping the PCB flush with the top-panel is pretty damn intuitive.
What is under your button though? An smt push-button? Can it be powered via the Gameboy?

You're going to love this...

It's a full sized push button. There's actually a huge hole right in the middle of the PCB to accommodate the footprint.

I considered using a through hole PCB mounted button, but it took up too much space. I don't know SMT yet :-(

Wow! That's fabulous!

Looks like you found the perfect case for the little guy. Must have been a super tight fit.

I'm building one more as a demonstration for an Instructable. I'm hoping to move on to the larger synths that MFOS puts out PCBs for. Ideally, I'd like to get away from handwiring stuff in general. It takes SO much time which requires me to push the price up higher than I'd like.

If you're interested PM me!

Thanks Peter.

That button is a bit temperate, but totally gets the job done for the AB and looks pretty doing it!

I'm actually from West Point. My father was an officer who worked at the counseling center (please note, I didn't attend school there). Currently residing in Brooklyn. Got into chiptunes, because I was the sound tech at the Tank where the monthly Pulsewave was held a few years ago.

Plebe year... sucks. I don't think you're even allowed to have a car until your senior year and even then there's basically no parking on campus.

There's a bus that runs on the weekends from West Point to the Metro North stop at Garrison. It's probably a 2 hour trip in total just to get to NYC.

Hit me up if you ever make it into town. It'd be great to share West Point experiences!

I was really dying for Meow to kick in at some point.

Also, anyone else notice how precariously mounted those LED Projector Cubes (capitalization totally appropriate) are?

i made a pcb for them haha

OSH Park is the best.

Can't believe I haven't bumped into this thread before now!

I just started an online electronics shop and one of my products is a beautiful compact passive matrix mixer. You can find all the info on it here...
http://xiwielectronics.com/products/pas … trix-mixer

Unfortunately, I'm currently sold out, but am taking preorders for the next batch I'm putting together.

This version uses 100k Audio potentiometers with 100k mixing resistors. I used a higher value, because I imagine it being used by noise and feedback artists rather than for practical applications like a headphone mixer/distributor.

Does the aboy have the ftdi header to easily update the firmware? Do you have pics of the various colors?

There's no FTDI header, but the chip can be removed from its socket and flashed using an Arduino.

The only difference is the LED color. I don't have any photos of the lit LEDs, but this image shows the very subtle color differences.

Bottom row: orange, red, red, yellow.

I can post photos of them lit if you'd like, but it's basically what you'd expect from an LED.

Thanks again everyone. A dream of mine finally came true today. The passive matrix mixer was posted on NOTCOT.org!

Also, I thought the completed Arduinoboy price was kind of high so I brought it down.
