myDAQ Guitar Effects Pedal
For my project, I plan to make my own digital guitar effects pedal. I plan to use a myDAQ and LabVIEW as tools to analyse the frequency content of the signal coming from an electric guitar and to create algorithms in LabVIEW to influence the frequency content of the sound so to create different effects. I plan to analyse how existing effects pedals influence the frequency content of the guitar’s sound signal to get some intuition with regards to what happens to the signal in the frequency domain when different effects are applied to it. From this I hope to gain experience with LabVIEW and analysing signals in the frequency domain and to get a “feel” for what goes on inside guitar effects pedals with the aim of eventually producing my own effects pedal with the algorithms I write in LabVIEW.
Inertial and Gyroscopic Sensors for the Formula Student Car
I joined the Electronics club in January and I am currently working on a project aiming to study how acceleration is affected by external factors and in a further stage applying this study to the Formula Student Car. This project will firstly go through an instrumentation process, where I will use acceleration and gyro sensors combined with CompactRIO and LabView. These two sensors will be firstly implemented in a bus wheel (which is owned by the university for research) in order to: figure out what type of data we can collect from that experiment as well as familiarise with the circuit and also try to improve the functionality of it, as for e.g. try to add a wireless communication link between the source (sensors) and the receiver (CompactRIO). As I already mentioned, to collect and read all the data in real time, I intend to use CompactRIO, which will work as the data receiver and also LabView, which will be used to programme the CompactRIO, both powered by National Instruments. After this instrumentation process, I want to implement this circuit in the Manchester Formula Student Car and try to collect the real acceleration data, in order to discover which factors are influencing the acceleration and what we can do to improve it. All this data will help me study if it is possible and viable to build a KERS (Kinetic Energy Recovery Scheme) for the Manchester Formula Student Car.
Bicycle Wheel POV System
The final outcome of the project is a system which will switch on and off individual LEDs in a row of these mounted across the radius of a typical bicycle wheel. The switching will have to have precise timing so that when the wheel spins, a picture may be formed in the retina of the viewer. The project will start by obtaining power from batteries and only using one colour of LEDs. Further development will attempt to obtain the power from the movement of the bicycle itself and the use of RGB LEDs to obtain a full colour picture.
To design and build and Quadrocopter (refered to as vehicle from this point), which will be capable of navigation given a distance and bearing. Additionally, wireless communication will be used to allow for manual control of the vehicle as well as monitoring the vehicle’s statistics. Given the ability to reprogram the Flight Controller, an additional aim is the build the vehicle such that it has extra weight capacity which will allow extra peripheral devices and functionality to added or changed, as required.
Water Saving Timer/Sensor
For the school for EEE’s Electronics Club, our team have been tasked to produce a system that will be used to reduce the amount of wasted water used to clean urinals. Currently, urinals in the university are controlled via a timed flushing mechanism which wastes a very large amount of water; essentially cleaning them even when they don’t need to be cleaned. The university have been tasked with reducing the overall water consumption by at least 20% in order to increase environmental efficiency, therefore this project will play a major role in aiding the university to meet that criteria. Our intention is to develop a system which will sense if there is anyone present in the bathroom by using infra red sensors, and by using this information alongside user initialised minimum flushing delays and information on previous flushes, system will be able to control whether or not a flush is required.
The advantage of using an electromechanical system to control the flushing also allows our team to implement a pulse-width modulation control of the solenoid valve in order to control the intensity of the flush. By incorporating a Java based control application which connects wirelessly to the system (Minimising the requirement for hands on interaction with the device), we will be able to store information about the current amount of flushes and display these via a GUI to the user. This feature will allow the university to compare the total amount of water being consumed and compare it with the default amount that would have been wasted had the system not been implemented. Our team have chosen to incorporate a light dependent resistor, going beyond the specification of the end user, which will be able to detect if the lights have been left on or off over certain time periods and produce graphical data based on these results via the Java based GUI in order to prompt the end user to avoid leaving lights turned on in future.
Semi-Automated Braking System for Road Bicycle
The aim of this project is to devise a system to help to prevent two, while uncommon, potentially highly dangerous situations encountered while cycling. These problems are: Overheating wheels causing failure of tyres, and wet brake pads performing poorly. I hope to produce a system to aid cyclists to avoid these potentially dangerous situations.
