1000 Volt DC to DC Regulator Circuit Input voltage from high voltage DC DC converter is 12V AC at 800mA current and then converted to DC through a bridge rectifier Diode 1A. The voltage output of converter circuit can be adjusted in the range of 0-1000V DC. This high voltage DC DC converter uses the [...]
RC5 is not suitable as a barrier to race out to whoever is the winner. Two or more RC5 channel interfere with each other and the protocol itself also takes time for the transfer. If more than one car with RC5 transmitter arrive close together, it can well be the first and the second triggers [...]
This circuit is a stereo amplifier for a high sensitivity stereo parabolic microphone that able to used for listening to distant sounds. Typical parabolic microphones are monophonic, this unit has a stereo audio path that helps produce more realistic sounding audio. The Big-E can be used with headphones or as an audio source for a [...]
Every electronics engineer is familiar with the anxiety of the moment when power is first applied to a newly-built circuit, wondering whether hours of work are about to be destroyed in a puff of smoke. A high quality power supply with an adjustable current limit function is an excellent aid to steadying the nerves. Unfortunately [...]
With the astonishingly rapid growth in the market for flat-screen TVs and high-definition TV, many CRT television sets have been consigned to the attic, even though many of them were still working perfectly and could have been used as spare sets in a bedroom or another room, for example. Although all current flat-screen receivers have [...]
Here’s the simple design allows ATV to be transmitted from a low-power (up to about 3W) FM or CW transmitter. Ideally the transmitter should use CW mode and have its ‘key’ down but an FM rig will work just as well if the microphone is disconnected and the PTT switch is closed. The only reason [...]
Circuit Description There are many instances where a simple and reliable power amplifier is needed – rear and centre channel speakers for surround-sound, beefing up the PC speakers, low powered tweeter amplifier, etc. For those who want to build their own ‘Gainclone’ amplifier, this will certainly do the job This project (unlike most of the [...]
