The PIC programmer project presented here is intended to be used by more experienced developers who already have access to a simple PIC programmer, because the programmer hardware is built around one 16F627(A) or 16F628(A) microcontroller that has to be preprogrammed with firmware. The presented solution uses PC's serial port for reliable communication between the programming software and 'intelligent' PIC programmer hardware.
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]
