The digital clock circuit board using LM8365,alarm and relay control, alert 2 times in 24 hour,backup battery power outage. Show dates, months or seconds
This is building the electronics workbench table,We like this desk, but expensive. so want to build myself. Can fit into the space, proper the height.
The TA8225 is BTL audio power amplifier for consumer application. It is designed for 45W high power. Operating supply voltage: VCC = 9~18V
Chayapol do everything as the solar cell system. I think it is useful, therefore, to buy a solar powered small fountain Kits it created a lot easier.
This is daylight sensor switch circuit, for control load turn on when have sunlight. use simple circuit LDR,transistor,relay and can use with 12V supply
Here is an adjustable dual-output regulated linear power supply Kit. It is capable of outputting positive or negative voltages from +/-1.2VDC to +/-15VDC.
