Brian's Earth Science Electronic Projects
Here are Brian's videos showing how to build some Earth Science electronic projects. These were recorded in May 2022.
You will need specific electronic parts, plus some additional tools and supplies.
FutureVision Research's Electronics Essentials Kit, provides all the electronic parts needed for these projects. (Multimeter is sold separately.)
Light Listener
In this project, we’ll build a project to listen to pulses of light that come from fluorescent bulbs and other sources. We’ll use two integrated circuits (IC) called operational amplifiers to increase the signal from a phototransistor. We can then listen to that signal by using a speaker.
Monitor Sunlight
In this project, we’ll build a circuit to measure light from the sun and other sources. We’ll use an integrated circuit (IC) called an operational amplifier to increase the voltage from a solar cell and measure the output using a multimeter.
Wind Speed
In this project, we’ll build a device that uses wind to spin a DC motor. We can then measure wind speed using a multimeter.
Earth Movement Sensor
In this project, we’ll build a circuit to detect the motion of a magnet. We’ll use an integrated circuit (IC) called an operational amplifier to light up an LED when a magnet moves over a coil.
Sun Photometer
In this project, we’ll build a circuit to measure light using a LED. We’ll use an integrated circuit (IC) called an operational amplifier to increase the tiny voltage caused when light hits an LED.
LED Telemetry Transmitter
In this project, we’ll build a circuit to measure temperature using a special kind of resistor called a thermistor. We’ll use a special integrated circuit (IC) called the 555 timer to change the blink rate of an LED based on temperature.
Electronic Cricket
In this project, we’ll build a circuit to measure temperature using a special kind of resistor called a thermistor. We’ll use an integrated circuit (IC) called the 555 timer to change the rate of “chirps” based on temperature.
