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.
Here is ic 555 inverter circuit. is easy and small size. Because use NE555 and MOSFET as main. When use source is 12V battery will have output of 100 watts.
The digital clock circuit that electronic amateurs are most interested. And The clock ICs that most popular are LM8361, MM5387,
