Electronic Maintenance third year students introduce their interesting projects:
REFLEX MACHINE
Student’s name: Iñaki Gaizka López Iglesias
Let’s see how it works!
The objective of this project is to make a mock-up that replicates a commercial Batak or reflex machine, improving its design while reducing costs. More applications will be added in the future.
As pilot lights turn on randomly, the reflex machine player has to press the lit button as fast as possible. These machines are used as training tools for athletes and in gaming rooms.
Our model replaces traditional buttons with copper plates that work as capacitive pushbuttons. This innovation significantly improves the machine, for most of its breakdowns are the result of players impacting against it.
VALVE AMPLIFIER
Student’s name: Gonzalo Caraballo
Let’s see how it works!
This project consists of designing and manufacturing an electric guitar valve amplifier.
Valve amplifiers are considered the height of a sublime audio experience by guitarists and scholars. These amplifiers combine crystalline and silky sounds owing to a low harmonic distortion in its active working region. Sounds are thick, corporeal and pleasing in its saturated amplification due to odd harmonics natural generation. This happens as a result of the technical characteristics of vacuum valves.
A boutique amplifier of unique sound features and characteristics has been developed for this project.
ROBOTIC ARM
Student’s name: James Echevarría
Let’s see how it works!
This project consists of developing a robotic arm equipped with a tool at its end that can perform multiple tasks such as welding, drilling or writing. The tool is operated by a worker who will set the coordinates of the working area.
NIXIE TUBE CLOCK
Student’s name: Juan Ángel Alcántara
Let’s see how it works!
The project consists of manufacturing a Nixie tube clock. The resulting clock combines modern and classic technology with an Arduino microcontroller, which requires a specific hardware and software design.
The block scheme is divided into three interconnected parts:
- Six Nixie tubes indicating the hour, minutes and seconds.
- A power supply, with an input voltage range of 9 to 12 V and an output voltage of more than 200 V.
- A PCB with an Arduino Nano programmer to control two SN74141 integrated circuits, one PCF-8563 real time clock module and one HC-06 Bluetooth module that allows the clock to be turned on with a mobile device. A resistance circuit, a BJT NPN (MPSA42) transistor and a PNP (MPSA92) transistor have been used for tube conduction.
3-FLOOR LIFT WITH ARDUINO
Student’s name: Rubén Compañ Cabrera
Let’s see how it works!
The objective of this project is to operate a lift with Arduino.
A three-floor lift mock-up has been designed to test the Arduino code. On each floor there is a button to call the lift. A red LED indicates which button has been pressed. At the top of the elevator there are three yellow LEDs that indicate which floor the lift has reached.
FIRE ALARM PANEL
Student’s name: William Patricio Chicaiza
Let’s see how it works!
The purpose of this project is to develop and set up a domestic fire alarm panel.
