Simple IC TDA2822 Stereo Audio Amplifier Circuit is small chip with stereo amplifier makes weak music sound go louder which is strong enough for speaker or headphone. However, despite using very little energy it still provides 250 milliwatts each side with good sound for small things like walkman, hearing aid or little stereo. So next […]
Solar Powered Animal Scarer Circuit
First of all, this Solar Powered Animal Scarer Circuit is very simple and very useful project for farm, garden and home protection. To begin with, it use solar energy, so it save electricity and work in eco-friendly way. Moreover, it scare animals like cat, dog, monkey and birds by using flashing light or sound signals. […]
Full Duplex Audio Line Circuit
To begin with, Full Duplex Audio Line Circuit is like a strong talking line, where two people can talk at a same time on one wire like a phone call. Not like a walkie talkie where only one person talk and other wait; but with full duplex both people talk anytime like a actual talking. […]
Heatsink Temperature Protection Circuit
Think heatsink like small radiator for our devices which help keep cool. Heatsink Temperature Protection Circuit is like safety man for that small radiator, as it got small sensor by always checking heatsink heat. Also, if too hot like one have got fever then this circuit does something, as it maybe a stop power or […]
Simple Static Electricity Detector Circuit
Simple Static Electricity Detector Circuit is like alarm for electricity when gathers on things like clothes and this happen when we rub things together. Also, this kind of electricity can break small electronics, so detector is useful near them; also detector have special sensor which feels electric change in air. Maybe its wire stick out […]
DC Voltage Doubler Circuit
DC Voltage Doubler Circuit is like small power booster, which takes normal battery power and make almost double. Also, it use smart parts like diodes and capacitors and they work like tiny switch and small electric bucket; sometimes many also use transistor or tiny chip to help. Imagine electric flow from battery like small stream, […]
