The LM350 is a tried and true 3A adjustable voltage regulator. It accepts an input voltage up to 35V and can deliver an output voltage between 1.25 and 33V. It is rugged beyond belief. Where fairly beefy step-down converters go up in smoke, the LM350 just takes a nap. And a nap is infinitely better than a plume of smoke. LM350 can also be used to limit current though that requires a separate LM350/LM317 in series with our voltage regulator.
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]
