LC meter project and kit - L/C Meter IIB
The L/C Meter IIB is a hand-held, digital inductance and capacitance meter with a sixteen character LCD with four digit resolution in each mode
Lcd 20x4 con pic16f887 come microcontrollore
Con il simulatore picsimlab proviamo il display lcd 20x4
La TV sul monitor del PC
Realizzare con pochi componenti, un’interfaccia in grado di convertire ed inviare il segnale VGA proveniente dalla scheda video del PC ad un televisore
LC Meter con 16F84
Ho trovato il progetto di un economico misuratore di induttanza e capacita' relizzato con un 16F84

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
30 Volt Computer Power Supply Stack A bonus was that i discovered that these did not need a standby load connected to the supply to keep them running just apply mains power and close the Start lead to ground
