Features PLL tuned transmitter / exciter for rock solid frequency stability over the entire FM band. Displays Transmitted Frequency on backlighted LCD. PCB includes antenna output to which a piece of wire, or VHF amplifier can be connected for greater transmission range. Includes 3.5mm audio jack cable. Plays MP3 from SD and USB memory (SD and USB connectors on board). IR Remote can be used to control the transmitter.
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]
