Young inventors invertopedia T-shirt

The impatient inventor t-shirt is the perfect solution for those who love to invent and create projects and need vital engineering information to hand immediately, upside down so the wearer can read it! The Invertopedia contains upside-down information on components including transistors, regulators, diodes, op-amps and the 555 timer. There are reference circuits with their associated formulae, handy lookup information on resistor color codes, Si units, logic gates, C/C++ operators and flow control and a full set of equations for Ohm's law.
