This board can program an AVR microcontroler ATMEL (ATmega8, ATMega32, ...) from a parallel printer LPT1 using ISP functionality In System Programming. This programming type can program and/or configure microcontroler directly on the target board without rmoving device and put it on a separate programmer. This board is compatible with programming software "PonyProg".
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]
