Hello.
I'm interested by this project.
How You planning to manipulate this device? (computer/handmade console with joysticks and buttons etc.)
Or, may be, device will follow cusrves using some sensors (for example, ultrasonic).
I'm working in electronics and programming last 15 years. Working with Arduino and different Atmega MCUs since 2008. Worked with stepper motors and different sensors.
2 weeks (and specifyied price)- it's real conditions for this project (for 'console manipulated' variant). Of course, Your busy schedule (and, sometimes, mine too) may add predictable delay.
My local time is GMT+2
I can communicate with You (and remotely working for project debugging) any weekday before 7 AM and after 18 PM and any time on weekend.
We can use both verbal and writing communication.
During working hours i'm usually available, but sometimes not sitting near to computer.
WBR
