This really gives hope to the world.
Students who have figured this out on a budget of nothing and then gave the machine as a donation.
It really took the ingenuity of students and young people to figure this out.
Strange how all the universities and firms awash with money and grants didn’t crack this decades ago.
Maybe they were all too busy inventing new bombs and wmd’s, perhaps??
How about making the world a better place, like these students?
