SUTD IEEE-HKN First Radio Workshop

Event Type: Workshop / Outreach

Date of Event: 09/03/2018

Today (9th March 2018) marks the first ever SUTD IEEE-HKN workshop on FM Radio Antennas for students enrolled in the Electromagnetism and Applications course in SUTD. This was a club endeavor to teach beyond the current scope, and more crucially to entrench the importance of the subject and its growing relevance in the modern world today beyond the academic syllabus.

The session had a great turn out and was oversubscribed, much to the club’s interest in spreading an EE mindset in SUTD. Sam and myself formally started the session by giving an in-depth overview to how radio signals and various receivers work. Alongside the amplitude, frequency and phase modulation, their underlying mathematical concepts were also thoroughly covered, drawing many questions from the students who took the opportunity to learn as much as they could during the course.

After a well-deserved lunch break, the participants got the opportunity to put their new-found understanding into practice by manufacturing a radio receiver circuit. They worked hard to ensure precision in their calculations and in their inductor designs. Finally, they were challenged to solder the various lumped-elements on their strip-boards in hopes of detecting static or noise, which could be further tuned to detect signals from Singapore’s public radio stations.

SUTD IEEE-HKN PCB Design and Milling Workshops I & II

Event Type: PCB Design and Milling Workshop Series!

Date of Event: 14th Feb and 21st Feb 2018

SUTD’s Eta Kappu Nu chapter is bustling with activity once again, as we are pushing for more initiatives to cultivate a strong electrical and electronics passion in our students!

Today, marks the end of our series of printed circuit board and design workshops! We held a total of two workshops, one on the 14th of February and one more on the 21st of February. We had a very welcoming response from all participants. The participating students had the experience of learning how to digitally design a simple circuit, and learn how to print. Below are some photos of the entire learning process and event!

In this workshop, students worked on circuit design using the EAGLE CAD software, the preparation of Gerber files, and the actual milling of the printed circuit board (PCB). EAGLE is a scriptable electronic design automation application with schematic capture, printed circuit board layout, auto-router and computer-aided manufacturing features.

We hope that it has helped many of our students in electronics and electromagnetics classes gain a fundamental understanding behind how the software works, and how it can be translated from a digital design to an actual prototype on the PCB mill. The students also learnt how to prepare the print files and to operate the LPKF Milling machines in the SUTD Fab Lab.

Night Light Circuit PCB

We used a simple “night light” circuit as a template for the students to practice. Essentially, the circuit works by having a 3V CR1220 battery power it up. When the light-dependent resistor (LDR) detects high ambient lighting, the voltage at the gate of the transistor falls to near zero, and shuts the current off passing through an LED, triggering it OFF. When the ambient light goes out, the gates to the transistors are “opened” as a high voltage is applied to the gate, and current flows through to light the LED. This was a simple enough example of a basic “logic” circuit for the students to follow. Although the preparation of the print files was tricky (and often ran into many errors…) we still had an enthusiastic response with the amazing turn out of curious, eager and passionate students.

We hope to organise more of such workshops to add value to their curriculum and their learning experience in EPD!

The 10th of September marked a major milestone for the pioneer batch of SUTD IEEE-HKN members. The education in SUTD has been a challenging yet fulfilling one.

Besides improving ourselves academically, the members are also grateful for the opportunities brought about through IEEE-HKN. It was through IEEE-HKN that we got to set up a workshop to share knowledge with our SUTD juniors, plan for exhibitions and outreach events, and even attend and help out in a conference. These experiences have definitely helped us develop in a holistic manner.

The graduation also ushered a change of leadership within the society, with new faces due to be introduced soon. We are confident that they would be able to help the club grow in the coming academic year. All the best, juniors!

Besides rewarding the industry partners, the session also presented the opportunity for school representatives and industry partners to interact and discuss about potential collaborative STEM outreach projects. On display at IEEE’s booth was an interactive musical circuit that took the shape of a cute little piano. The product, conceived by incoming SUTD students Leonard Hoe and Leong Hei Kern, requires only simple electronic components and operates using easily understandable concepts. As a potential starter kit to introduce students to electronic engineering, it managed to garner some interest amongst the educators present.

The event was an eye-opener for the members of SUTD IEEE-HKN. The team was inspired by the level of committment shown by the various entities in trying to make STEM outreach at primary and secondary school-level a success. In the near future, SUTD IEEE-HKN also hopes to be able to collaborate with some of the schools in promoting engineering to the younger generation.

Introductory PCB Design Workshop for SUTD Students

Event Type: Workshop

Date of Event: 05/02/2016

In order to make full use of the printed circuit board (PCB) prototyping facility in SUTD’s Fabrication Lab, one first has to learn how to design a PCB on software. Hence, SUTD IEEE-HKN held a workshop teaching participating students to do just that. The software of choice was the CadSoft EAGLE PCB Design Software.

Besides teaching participants to use the software, the workshop also aimed to provide tips that would be relavant to an SUTD student. This includes designing with the limitations of SUTD’s prototyping machine in mind, as well as some troubleshooting tips. The participants were also given a copy of SUTD IEEE-HKN’s self-written tutorial, which would allow them to practice on the software by following step-by-step instructions in constructing and readying a circuit for fabrication. With this workshop, we hope to be able to see more quality projects making use of the PCB prototyping machine in school.

EM Workshop for Anderson Junior College Students

Event Type: Workshop / Outreach

Date of Event: 20/01/2016

Following the trial run conducted earlier this month, SUTD IEEE-HKN today conducted the EM Workshop for 22 Anderson Junior College (AJC) students. These students were from the Science Club in their school, and they all share a strong passion in science and research.

The workshop, which covered the entire process of making a patch antenna, was kicked off by Prof. Shaoying’s short lecture on Electromagnetism and its importance.

11

The students then proceeded to design their patch antenna using a commercial software. Besides calculating the performance of the designed antenna, the software also allowed the students to visualize the propagation pattern of their antennas, as well as optimize certain design parameters to improve their performance. The lesson was conducted by our president Wei Jian, while other HKN members were on hand to provide guidance along the way.

IMG-20160120-WA0011IMG-20160120-WA001022

After getting the antenna design completed on software, it was time to proceed to the actual fabrication. The fabrication was done in-house in SUTD’s Fab Lab, where there are two PCB prototyping machines which can be used to mill the patch antennas.

33

While at the Fab Lab, the students were also treated to a tour around the facility. The two-storey facility is home to a wide variety of fabrication and prototyping machineries, and it was an eye-opener for the students.

44

The final part of the workshop involves the testing of the fabricated antennas. Using a Virtual Network Analyzer (VNA), Prof Shaoying helped to quantify the performance of each antenna. She also conducted a series of simple experiments to illustrate how distance, direction and polarization can affect the transmission and reception of electromagnetic waves.

IMG-20160120-WA0009

Besides teaching the AJC students about Electromagnetism, the workshop was also an opportunity for them to engage with the staff and students of SUTD, and to further their understanding of the university’s culture. The students ended the workshop with their self-fabricated antennas to boast as souvenirs.

A special mention to our lecturer Dr. Lee Chee Huei for his sharing on EM and SUTD’s pedagogy in today’s workshop! Also, we would like to thank our fellow coursemates in Stanley and Sabareesh for acting as both teaching assistants and tour guides for the event!
