To tell the truth, I was really touching the SCR time is not long, before I only know this thing function similar to relay, the main control AC load switch. What BT136, BTA06, BTB06 was first seen in an automatic mahjong machine. Because it has always been the study of digital hardware programming or a yard farm, these also disdain, as coarse things.

Open SCR screen Recorder, display the video Control Panel , click "Start" button to start recording;-There are two ways to stop recording. One is the lock screen, the lock screen after waiting for 2 seconds, the video file will be automatically saved to the SD card, the other is to reopen SCR screen Recorder, usually SCR will be resident in the notification bar,
Can be used in single-chip microcomputer controlled SCR circuit, can reduce the volume and weight of the product. ......Why separate with R1, R2, R3? Are they all strung together, with a resistor?Landlord has done 0 testing what to do with?1, in order to increase security2. Control the output power of SCRIf you need to be very precise, you can use a voltage comparator after the resistor is divided, then the OptocouplerLandlord is in order to adjust th
Considerations for installing MySQL source code scr. rpm
The rpm installation package is usually a Binary package or a Source package. When using the source code to install MySQL, the source code package downloaded on the official website is usually scr. rpm format, rather than the direct tar package.

The general TS version and the repaired clear TS version are often found on the forum3. TC (film version)TC is the abbreviation of telecine. TC uses a TV-movie machine from a direct digital copy of the film. The picture quality is good, but the brightness is not enough, some dim. Many times the sound source used to make the TC comes from TS, so the sound q

A single data stream composed of one or more pes with a common time benchmark is called a program stream ).
ES is a data stream directly from the encoder. It can be a collectively referred to as an encoded video data stream, audio data stream, or other encoded data streams. The es stream is converted to the PES package after it passes through the PES package.
Composition:
The PS package consists of three parts: Baotou, system header, and PES package.Header starting from PS packa
