7400 competition entry: 4049 inductance meter

Posted on Wednesday, October 10th, 2012 in 7400 contest, contest by DP

Mike’s 4049 inductance meter converts inductance into voltage, which can be read via any multimeter. Check out the latest Open 7400 Logic Competition entry:

All the decent multimeters nowadays seem to have a built in capacitance meter, but only a few of the really expensive ones have a built in inductance meter. Dedicated inductance (LCR) meters, of course, are also really expensive.

The solution, of course, is to build an inductance adapter for any multimeter.

Build something that uses or abuses a logic chip and get amazing boards, tools, and other swag. The Open 7400 Logic Competition promotes awareness of the basic building blocks of modern circuits. Devious geeks ignited the computer revolution with discrete logic computers, what can you do? Details and entry form here.
