The school can send you an text message to inform you your kid will quit 2 hours early. Problem solved.

Not everyone works in an office, though.
It was maybe 7 years ago, and I guess now they have a single µC containing the DSP and able to speak USB, do the dithering, and control the motors all in one package. There is almost no R&D in those markets. That's how you get a $20 printer (and $50 ink cartridges).
Do no count on printing on PCBs or fabric, that'll be R&D, and that's expensive, no one cares up there.
Would you mind to source and explain that ?
Can you explain how it useful as a research project ? What are you expecting to learn overall ?
Thank you.
