555-timer-beeper

In order to build 555-timer-beeper you will need theses components

- 555-timer ic
- 1 mega ohm resistor
- 1killo ohm resistor
- piezoelectric buzzer
- 100uf capacitor
- jumper wires
- Small batteries

The circuit is a basic 555 timer astable mode. In this configuration the IC sends a brief pulse to the buzzer every few minute.

How to make a very simple crystal radio

Image
Crystal Radio. I have created a crystal radio just using one germanium diode and a magnet wire and will also need a crystal earpiece or you can us audio amplifier. (I use germanium diode because this diode has low voltage rating then other diodes) When my radio receive the signal from the air it is alternating current, but our diode rectifies the AC signal and only allow the positive signal pass through. Finally the signal goes through the ear piece or the amplifier  so that the human ear can hear. First step to create this is to wind a coil on a 10cm box and you will connect the end of the coil to the antenna and germanium diode. After that you will connect your crystal earpiece(amplifier) to the other side of the diode and connect the other side of the ear piece to the other side of the coil and to the ground(you can use your body as ground).

Broken Jump rope counter

Image
I had a jump rope with a counter on it. One day it didn't work. So I took the jump rope apart and then negative side was not connected to PCB so I connected. I also added a cheating button. This process took a lot of time for me beacuse the wires would not fit in. I noticed that the LCD display isn't connected by any wires. I think the pink thing has like little wires in them so if u attach it sends data. Unfortunately, I accidently took off the pink stuff from the display. So I couldn't fix the jump rope.
