Stefan sent in this Maker challenge, seems like there’s an opportunity to do something here…“in a dentist’s office waiting room [reading in a] copy of TIME, that a full-blown Avian Flu pandemic would seriously stress the nation’s supply of ventilators . . . those bellow-and-tube gadgets that keep your chest going up and down when you can’t breath on your own. This suggests a topic for a MAKE Challenge: A DIY ventilator! Only for use in serious, horrible, unthinkable circumstances, but [stuff] happens and it would make for an interesting project. Extra credit if it runs off of a 12 V battery. (Or maybe not…a possible design I’m thinking of right now would use a windshield wiper motor set to intermittent).
