Kedua sirkuit yang multi-range timer menawarkan jangka waktu sampai 24 jam dan seterusnya. Keduanya pada dasarnya sama. Perbedaan utama adalah bahwa ketika waktu habis, Versi 1 energi pada relay dan Versi 2 de-memberikan energi itu. Yang pertama menggunakan daya yang lebih kecil, sementara timer sedang berjalan, dan yang kedua menggunakan daya yang lebih kecil setelah timer berhenti. Pilih satu yang paling sesuai dengan aplikasi Anda.
The Cmos 4060 adalah counter biner 14 bit dengan built in osilator. Osilator ini terdiri dari dua inverter terhubung ke Pins 9, 10 & 11; dan frekuensi diatur oleh R3, R4 & berkedip C3.The Led hijau sedangkan osilator berjalan: dan IC menghitung jumlah osilasi. Meskipun sedikit 14 counter, tidak semua bit dapat diakses. Mereka yang dapat dicapai akan ditampilkan pada gambar.
This is a circuit of an audio amplifier for the guitar. This circuit can reproduce a Combo amplifier of the type very common in the 'Sixties and the' Seventies of the past century. It is well suited as a guitar amplifier but it will do a good job with any kind of electronic musical instrument or microphone.
5W power output was a common feature of these widespread devices due to the general adoption of a class A single-tube output stage (see the Vox AC-4 model). Furthermore, nowadays we can do without the old-fashioned streetcars VIB-feature frequently included in those designs.Read More...
Most battery chargers cannot be left connected to the battery for long periods of time as over-charging and consequent battery damage will occur. This add-on circuit is placed in series with the battery being charged and is powered by the battery itself. In effect, the circuit uses a high-current Mosfet to control the charging current and it turns off when the battery voltage reaches a preset threshold. Power for the circuit is fed from the battery to 3-terminal regulator REG1 which provides 8V .Read More...
Volume Digital Stereo
An array of well-matched resistors and a low noise active output stage that is capable of driving a 600 Ohm load is included in this device. Through 95.5 dB attenuation and 31.5 dB of gain , a total adjustable range of 127 dB, in 0.5 dB steps, is achieved.
