LC meter is a handy device. Probably any hobbyist can find C meter on their multimeter while L meter is rare feature on common devices. If you feel that you need compact and reliable LC meter then check this one. This is actually slight remake of Phil Rice original LC meter that was designed quite some time ago. But this circuit seems to be time proved and can serve as good reference for new one.
Among changes there is a Li-Ion battery that replaces 9V pack. So this needs a 5V voltage booster and charger circuitry to make it work. Mini USB connector were added to make charging easy. Also there were minor changes made to firmware where recalibration were fixed. Board was placed in to nice box and now looks really pro.
