Hey, i found this on my travels: computerless Arduino
and they quote:
Here’s a fun hack we’ve been experimenting with — a computerless Arduino! It’s small, inexpensive, and doesn’t require a computer to change the code, so you can take it with you and make awesome things anywhere.
The Computerless Arduino consists of two major components; an Arduino-compatible microcontroller loaded with a realtime code interpreter, and a stand-alone 5 button LCD display to display port values and manipulate code. The display can be connected to the Arduino via a 4-pin port at any time to peek at In/Out values, view the current code, and make changes as desired.
By keeping the display separate, it’s possible to have many dedicated Arduino modules (we’re using one of the smallest, cheapest, and most-capable Arduino clones, the Teensy2.0 for $18), without needing to spend much on each additional device. For the display we’re using the super small uLCD-144 (by 4D Systems for $29), and the system could easily be modified to use a larger display or computer if desired.
The programming instruction set for the Computerless Arduino is quite small, making it easy for novices to get started while still working with real code. Navigating the user interface is a bit tedious on such a tiny display, but it’s easy to learn and provides everything you need — a basic multichannel signal scope, a code page for the setup() function which runs once at startup, and 8 pages of code for the loop() function which provides the main functionality and runs over-and-over forever.
The code for the Computerless Arduino is still quite experimental, but it’s all here. As always, Labs work is open source and creative commons, so if you’re curious to play with it yourself or build derivative work, have at it!

We’re still noodling on where to take it next, but there definitely seems to be something interesting about non-conventional approaches to embedded development.
now i may not have the same gear, but wat i do have should be enough, a spi display of the same dimentions (works with the adafruit demo code for such displays), and an Arduino Nano. should this not be enough?
but upon trying to compile the code in the IDE i get this:
ComputerlessArduino_12:33: error: no matching function for call to 'HardwareSerial::HardwareSerial()'
K:\arduino\arduino-0022\hardware\arduino\cores\arduino/HardwareSerial.h:50: note: candidates are: HardwareSerial::HardwareSerial(ring_buffer*, volatile uint8_t*, volatile uint8_t*, volatile uint8_t*, volatile uint8_t*, volatile uint8_t*, uint8_t, uint8_t, uint8_t, uint8_t, uint8_t)
K:\arduino\arduino-0022\hardware\arduino\cores\arduino/HardwareSerial.h:32: note: HardwareSerial::HardwareSerial(const HardwareSerial&)
im not sure wat to do in order to make that one thing ok, let alone any other error that may be pooed out.
its bad enough they dont tell u how to build it but when the code wont compile because of that then how else u supposed to work it out?
if anyone else knows of this project and can shed light on it then i'd be happy.
