This week, Editor-in-Chief Elliot Williams and Contributor Emeritus Kristina Panos gushed about all the best hacks of the previous week. But first, a contest! That’s right — hot on the heels of the Low Power Challenge comes the Op Amp Challenge, sponsored by Digi-Key. You have between now and June 6th to dip your toes into the warm waters of analog and show us what you’ve got. Will it be a musical hack? Will you seek high analog precision? We can’t wait to see.
Kristina definitely did not get What’s That Sound this week, which honestly reminded her of a cartoon character getting a piano dropped on them, except the sounds were in reverse order. Then it’s on to the hacks, beginning with a way to make an IBM Selectric typewriter use Comic Sans, a project that’s sure to make you a believer in graphene, and a miniature MNT for every (cargo) pocket.
From there we take a look at a really cool indicator from a 1960s RAF aeroplane and investigate why your multimeter might be lying to you. Finally, we discuss the gargantuan task of building an AR system to rival Google Glass, and the merits of taking a lot of pictures as you go about your hacks.
