Watch how Christmas lights are made

Alex Appolonia: Have you ever wondered how these bands of lights come together? It’s a simple string of miniature light bulbs, with some wiring inside that connects everything together.

Holiday light companies use various methods to make their string lights. Taizhou Haoran Machinery sells machines that create LED holiday light strings.

Here’s how it works.

First, the wire is fed into the machine so it can be cut and shaped. Then, it is stripped at the tip and coated with flux, a cleaning agent that makes soldering and welding of metals a little easier.

Next in line are the LED light bulbs. They’re fed into the machine and tested for positive or negative charges. Then, the metal ends of the lights are cut and shaped. Like the string, the LED light bulbs are also dipped in flux. The bulbs are then finally soldered with the wire.

The machine lines up all the stripped parts of the string with the individual light bulbs. The stripped ends of the string and the metal tips of the bulbs are soldered together. After the two parts are combined, each light is tested again for electric charge. Then the machine covers the metal piece in between the light bulb and the string with an insulator. The insulated lights are also wrapped with clear acrylic sleeves, to make them a little more durable. Lastly, the string is released and collected to go into the twisting machine.

And it comes out like this, bright and sparkling with colorful lights. Now, here’s the thing.

The machine makes string lights in a series circuit. In a series circuit, the current passes from the power source to the first light, then the next, then the next, and so on, until it returns to the power source and completes the circuit. In this setup, if one bulb burns out in the strand, the current won’t flow through the entire circuit, which means the entire string of Christmas lights will go out. Some of these could be replaced with a working bulb, but not all.

The other type of circuit light strands use is a parallel circuit. In this setup, each bulb is on its own circuit to the power source. The current is divided into paths, and since there is a separate path for each light, the rest of the bulbs will stay lit even if one goes out.

No matter what kind of lights the machine makes, they’re finally ready to be hung up on a Christmas tree.

By

OTTAWA — Major companies and government partners are lending their support to Carleton University’s newly established Women in Engineering and Information Technology Program.

The list of supporters includes Mississauga-based construction company EllisDon.

The latest to announce their support for the program also include BlackBerry QNX, CIRA (Canadian Internet Registration Authority), Ericsson, Nokia, Solace, Trend Micro, the Canadian Nuclear Safety Commission, CGI, Gastops, Leonardo DRS, Lockheed Martin Canada, Amdocs and Ross.

The program is officially set to launch this September.

It is being led by Carleton’s Faculty of Engineering and Design with the goal of establishing meaningful partnerships in support of women in STEM.  

The program will host events for women students to build relationships with industry and government partners, create mentorship opportunities, as well as establish a special fund to support allies at Carleton in meeting equity, diversity and inclusion goals.

VR tech to revolutionize commercial driver training

Published

Serious Labs seems to have found a way from tragedy to triumph? The Edmonton-based firm designs and manufactures virtual reality simulators to standardize training programs for operators of heavy equipment such as aerial lifts, cranes, forklifts, and commercial trucks. These simulators enable operators to acquire and practice operational skills for the job safety and efficiency in a risk-free virtual environment so they can work more safely and efficiently.

The 2018 Humboldt bus catastrophe sent shock waves across the industry. The tragedy highlighted the need for standardized commercial driver training and testing. It also contributed to the acceleration of the federal government implementing a Mandatory Entry-Level Training (MELT) program for Class 1 & 2 drivers currently being adopted across Canada. MELT is a much more rigorous standard that promotes safety and in-depth practice for new drivers.

Enter Serious Labs. By proposing to harness the power of virtual reality (VR), Serious Labs has earned considerable funding to develop a VR commercial truck driving simulator.

The Government of Alberta has awarded $1 million, and Emissions Reduction Alberta (ERA) is contributing an additional $2 million for the simulator development. Commercial deployment is estimated to begin in 2024, with the simulator to be made available across Canada and the United States, and with the Alberta Motor Transport Association (AMTA) helping to provide simulator tests to certify that driver trainees have attained the appropriate standard. West Tech Report recently took the opportunity to chat with Serious Labs CEO, Jim Colvin, about the environmental and labour benefits of VR Driver Training, as well as the unique way that Colvin went from angel investor to CEO of the company.

While the world comes out of the initial stages of the pandemic, COVID-19 will be continue to be a threat for some time to come. Companies, such as Zen Graphene, are working on ways to detect the virus and its variants and are on the forefronts of technology.

Nanotechnology firm ZEN Graphene Solutions Ltd. (TSX-Venture:ZEN) (OTCPK:ZENYF), is working to develop technology to help detect the COVID-19 virus and its variants. The firm signed an exclusive agreement with McMaster University to be the global commercializing partner for a newly developed aptamer-based, SARS-CoV-2 rapid detection technology.

This patent-pending technology uses clinical samples from patients and was funded by the Canadian Institutes of Health Research. The test is considered extremely accurate, scalable, saliva-based, affordable, and provides results in under 10 minutes.

Shares were trading up over 5% to $3.07 in early afternoon trade.
