Hello There,I attempted your project with one main difference : I used old scanners' stepper motors instead of DVD drivers' since they are bigger and also easier to connect the wires to since I find soldering to these small ribbon cables of the DVD drivers extremely painful. Anyway I checked all the connections, hardware seems fine so is software but when I attempt to move any of the axes (X & Y) it produces some whistle noise and that's it !!! I suspected the power outlet so I changed the phone charger from your block diagram above and replaced it with a PSU and still no moves and only whistles ! Any suggestions or thoughts on what went wrong & how to fix it ? Thanks in advance

I'm still trying to reach a visual impaired person to test it. So far I've tried using it on people who are short sighted and asked them to close their eyes even though it's not the same at all. Till then I will try to make the device smarter.
