it isn’t homework, I would appreciate it if you would not cuss k thx.
I’m struggling to find an Electronic device to do my assignment on. I don’t want people to do it for me, I just need help finding something basic to do it on, helpful websites and some tips.
Task: You are to select an electronic device that is used commercially. You are to describe the circuity of this device, explaining how the circuit works as well as explaining in detail the electronic components that make up this device. You may need to research components such as variable resistors, transistors, diodes and capacitors.
Your report will need:
- A circuit diagram of the major components
- An explanation of how each device works
- An explanation of each component and its function
Any help would be greatly appreciated!
I have recently gotten in the habit of taking off electronic components from motherboards, circuit boards, etc. and I want to know what the capacitance is of the capacitors I take off.
Any help?
Hi,
I’m building a simple circuit with two 4000 series logic ICs, an LDR and a buzzer amongst a couple of other things.
I’m not sure what type of capacitors to buy to go in it.
I need a 0.001 mf, a 10mf, and a 100mf capacitor but am not sure what type.
Please could you provide a link from this site:

of the type of capacitor I should buy. I am thinking electrolytic?
Thank you very much.

Hi, i’m having a little trouble. A schematic diagram of a 3-band equalizer is on this link: http://freecircuitdiagram.com/2008/11/25/3-band-graphic-equalizer-circuit/
Here’s a story. I went to a local electronic shop to buy the parts needed for that 3-band equalizer. When I asked the vendor for the capacitors, he asked me, "how much is the voltage? what kind of capacitor do you need?" and i just said, "i don’t know". The supply needed is 12V DC and the values of the capacitors are:
0.1uF
47nF
4.7nF
0.47nF
22nF
1nF
33uF
I’m sorry but I’m such a noob at this, but I’d really really appreciate it if anyone can help or tell me if there’s some sort of formula for this.
Thank You very much ![]()
I have small battery powered electronic toy that makes sound. I would like to amplify the sound to make it louder. I have a very basic knowledge of electronics, so I could add small capacitors or resistors to some wires, but anything involving complicated circuit boards or actually rewiring the toy itself are pretty much out of the question. Thanks…
