First Milestone

My First Milestone was to asemble the electronics of the hovercraft. My first step was solder the wire connectors to the wires attached to the fans to connect to the 2 ESCs (Electronic Speed Controllers). Then I soldered the ESCs to each other and to a wire connector in order to connect to the battery. My first test of the fans didn’t go so well, as I wasn’t able to secure and control them. In preparation for the next test, I secured the fan in the side of a cardboard box and test #2 went a little better as the fan was secure, but I still wasn’t able to fully control it. I then did some research and realized that the best channel to connect the ESCs to are channels 2 and 3 (I had previously connected them to channel 1). Test #3 went much better as I was now able to control the speed of the fan and turn it on and off. The most challenging part of this milestone was probably finding a way to secure the fan in place in order to be tested.

Starter Project

My Starter Project is the Light Organ, which is a device that flashes lights in a synchronized, methodical when it hears sound. When the microphone picks up a sound, a message is sent to the LEDs to light up in a certain way. A more detailed description of the Light Organ can be found in the video to the left and in the paragraph below. Throughout this project, I learned a lot about soldering, as every piece in the circuit needed to be soldered on.

How it works

After being connected to a battery, the microphone on the Light Organ picks up a sound and the LEDs flash in a synchronized, methodical pattern according to the sound picked up by the microphone. The ICs, or microchips, direct the current to everything else in the circuit. The battery is constantly sending electrical energy at a slow rate through the ICs, and that energy is stored in Electrolytic capacitors, and when the microphone picks up a sound, the capacitors rapidly send the energy that was stored inside them to the LEDs through the transistors, which regulate how much electricity flows by opening or closing a pathway for the electricity to travel through. The resistors then slow down the electrical current going to the LEDs, so that not too much electricity is sent to them so that they don’t explode.
