Thanks all. Up to 80 responses. Some surprising and not so surprising trends are developing. Hopefully others will find the data useful or at the very least interesting.

Hello friends,

As some of you may know, I am a student at Parsons the New School for Design in New York and am about to embark on a year long thesis project to satisfy the requirements for my master's. The details are rough, but generally speaking, I plan to create an open-source, affordable, and accessible modular system that interfaces over MIDI, OSC, and/or custom serial protocol.

In these early stages, I am still doing research and part of this process involves collecting data from the populations the device will be designed for. If you have a moment, please take a minute to complete a very brief survey I've put together to gauge electronic composers expectations of their gear.

Survey: http://bit.ly/1obFwhb (Please consider Gameboy as hardware)
Results: http://bit.ly/1wcIVlp

Thank you all so much for your time and I can't wait to share more details as the system develops. Very exciting times for me.

I'd like everyone to know that I won't be producing any more Arduinoboys following this batch. I've posted all my design files to a GitHub Repo for anyone who would like to continue producing them.

omg. almost forgot. i kind of used joshua morris' music without permission. if there's some hate on that part, i'll change it immediately to something not nearly as cool.

Hi friends,

I made a game for the monome. Hope you check it out!

Video: http://tiny.cc/wnc9bx
Patch: https://github.com/brendan-byrne/pushallthebuttons

This is my first monome patch and I think it probably shows. If anyone has any suggestions I'm all ears.

Cheers

Kits are now available...

I've gotten rid of the alternate pricing system.

Also, I've posted all of my documentation to a GitHub repo found here...

Assembled Arduinoboys are now back in stock.
http://xiwielectronics.com/products/arduinoboy

The assembly process took much longer than expected. It didn't help that the laser cutter I use has been out of commission for the past six weeks.

I've devised a new payment system in which you'll be able to chose between two prices. I do everything I can to keep the cost low without driving myself into the ground. I don't sell through distributors, because their commission would force me to raise the price drastically. Above all, getting chiptune instruments out into the world is my mission.

Kits will be available sometime next week if not sooner. They'll be priced at $55 - Starving Artist and $65 - Patron.

I'll also be posting a Git Hub repository with the schematic, PCB layout, enclosure documentation, and supporting files by the end of the day. Hope this information will be useful.

Post any questions you may have to this thread.

Thanks for the support, everyone.

Hey all...

CD4066 was a bust. The internal resistance on the chip around 500 ohms cancels out making a solid bend point connection. It works, just not the same way a relay did. Going to try MOSFETS and reed/photo relays to get better results.

Here's an update video though!

I just got a new batch of PCBs in yesterday. Working super stupid hard on my finals right now, so I won't be able to get em together for a few weeks. Hoping to finish them before Christmas. I'll post to chipmusic.org when they're up.

Here's the documentation link...
https://www.dropbox.com/sh/46izdrruncqw … /Doomtendo

The readme file contains most of the interesting stuff. Check out the link to Casper Electronics to find documentation on NES bend points.

Nothing too fancy going on here. Anyone who is thinking of building this, I'd recommend holding off until I have some time to post the solid state version with CD4066s. But if you want to turn a bunch of light bulbs on and off this will do the trick!

@kineticturle
whoah. total vj boner.
that's rad. i'm guessing you use the same patch bay/relay machine for the genesis? what is that thing? what's the other thing right next to it?

i found about 12 bend points i liked on the nes. it looks like you've found at least twice as many as that!

this is awesome though. i'm totally inspired to get this thing up and running and packaged as a simple, but super fun vj tool. next step is flashing custom roms to cartridges so i can control the color pallete/general movement of the screen. think no-carrier's work shouldn't make that too much of a problem

Hi friends,

I made a relay-based circuit-bending system for my NES. An arduino receives digital out information from a step-sequencer in Max. Maxuino and Firmata are used to facilitate the data translation.

-------- VIDEO --------
http://www.youtube.com/watch?v=xeRbeZSn … OhHAZv17mg                               

I'm cooking up a plan to make a kit version that will used some CD4066s, maybe digital pots, microcontroller, rotary switches, and MIDI IN to control bend points. You'd be able to house the circuit and all the hardware within the NES case. The kit would cost somewhere between $50 - 75.

Would anyone be interested in this? If not I'll probably kill it.
