Play episode · 1 hr

Kitty Yeung (@KittyArtPhysics) spoke with us about the superposition of quantum computing and fashion. 

If you want to learn more about quantum computing, check out Kitty’s series on Hackaday’s  Quantum Computing Through Comics

Kitty works for Microsoft in Quantum Computing (@MSFTQuantum).

Kitty’s art and fashion are available on her site, Art By Physicist, and shop shop.kittyyeung.com. Her recent addition is the Constellation Dress. There is a coupon code in the show.

Kitty has some other DIY fashion projects: Made of Mars and Saturn Dress.

MEP EP#246: Doing Something Magical
MEP EP#246: Doing Something Magical Parker * Physicists build circuit that generates clean, limitless power from graphene * University of Arkansas physicists * Energy harvesting the thermal motion of graphene * Without getting all quantum about it, it seems to work by configuring the graphene as one electrode (or both) of a capacitor. As the graphene flaps in the breeze (actually Brownian motion, I assume), the changing geometry will change the capacitance. * The team's next objective is to determine if the DC current can be stored in a capacitor for later use * Youtube video Stephen * New test equipment design - picking the right opamp * Current sensing with a bit of a twist * Powered by +/-12V * Need to read current on the +12 and the -12 along with a +9V rail * Opamp needs to be capable of reading a voltage drop in an environment where the common mode voltage is at or near the opamp supply voltage * Current sense amplifiers * INA1x9 series amplifiers from TI * Supply and common mode range are independent of each other * 2.7v to 60v * Convert a voltage to a current then change the gain by selecting an appropriate load * Iphone 12 doesn’t come with a charger? * Are chargers necessary? * Don't we have like 300 of them lying around? * Apple states environmental reasons for dropping the charger * Also no earbuds * Examples of other products that lack the equipment necessary to function * Video game consoles? * Appliances? * Internet router?
