This is Morning sun alarm circuit using IC-4011 that hobby It will have sound alarm when morning like a normal clock alarm with lighting sensor same clock.
Do you love music? Imagine we can build power amplifiers system. Sound good, doesn’t it? Here are many circuits. For example, about Audio amplifiers, bridge amplifier, Using transistor or IC or MOSFET, Mixer, Graphic Equalizer, Preamplifiers. And, Sound generators, tone controls, Melodies, Sirens, Animal sound, effect voices. Even, Burglar alarm, and more. I cannot explain to you all. But sure I do not like to see you miss them.
Imagine you are playing an instrument, a guitar. Sometimes you want a strange sound from a normal. Use these ideas of fuzz box circuits and fader controller. You may change…
This is Simple Solar light alarm circuit with the special edition, that improve this circuit whole new to higher efficiency. use solar cell instead of LDR
A tri audio amplifier has three in one amplification act drive specifically each audio speakers good quality, using TDA2030 and crossover network built-in [...]
Imagine your dad is old. Sure, he hears anything weak sound. How do you do? You are an electronics inventor, right? Yes, you can try to make a tool. To help him back to listen to great music again. This project is small, use only one 1.5V battery. Using normally components you can buy in stores near you.
This is Mini 40 watt audio car amplifier circuit using HA13001 on BCL system, so small and easy with PCB layout and can all 12V-14V power supply
