DIY Adjustable Bench Power Supply

Every electronics hobbyist needs at least one bench power supply in his house for tinkering with some weekend projects. This small power supply was built with an old 19V 3A laptop charger and buck-boost converter. Output voltage is continuously adjustable from 1.25V to 33V with up to 3A current. I have been using it for 3 weeks now and have realized that I am using it more than I thought I would.

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]
