A continuously alive wiper in a car may prove to be a nuisance, abnormally back it is not aqueous heavily. By application the ambit declared actuality one can alter across-the-board amount of the wiper from already a additional to already in ten seconds. The ambit comprises two timer NE555 ICs, one CD4017 decade counter, one TIP32 disciplinarian transistor, a 2N3055 ability transistor (or TIP3055) and a few added detached components.
Build Accurate LC Meter and start making your own coils and inductors. This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils. LC Meter can measure inductances starting from 10nH - 1000nH, 1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up to 900nF. The circuit includes an auto ranging and reset function to make sure the readings are as accurate as possible ... [more]
