BP Wealth Learning Centre

BPWLC Homepage

Our business is to impart skills through online as well as offline courses and projects related to mechatronics and financial courses.

A number of mechatronics projects have been included in the webpage below, and we will add more whenever appropriate. These are either niche projects or even new inventions. We believe that 80% of the population may not know how to do, or perhaps, not willingly to do. In addition, we also provide on-line mechatronics-related courses such as 3D printing and Fusion 360. More online mechatronics courses on such projects can be found under the courses tab.

In addition, we also provide online financial courses. The financial courses can be viewed under the courses tab too. Viewers may view the financial blog under the blog tab on this webpage.

Today’s highlight

One key purpose of 3D printing is that we can fabricate something on the spot. Unlike in conventional manufacturing process, we need to make a mould even for a simple part as shown below. The whole process, at its fastest, would require at least 4 to 6 weeks to complete. And, very importantly, the cost of the product becomes very, very expensive due to cost of producing the mould.

 

This is a toilet slider stopper. The function of this stopper is to prevent one flap of the sliding door from sliding along its rail. In simple engineering term, this is to convert a slider into a pin-joint while the other flap remains as a slider. By doing so, the door will not inadvertently fall as one joint is now hinged while the other flap can still slide on its rail freely when opening or closing the door. From the load point of view, it is the least of the problem. It only acts as a stopper to keep the hinged part of the sliding door in position.

 

The original plastic was made from an injection mould. Why was it able to make from injection mould was that during the building construction, tens of thousands of identical pieces had been fabricated for many households in the whole development. Therefore, the cost of that part had been amortised over the number pieces that were fabricated. However, for each household when the part is broken, it is not possible to get that part easily. Even if the owner is able to procure the part from the original door supplier, it is likely to be extremely expensive. However, the situation is that the door supplier will not want to supply the house owner only for that part. The supplier wants the house owner to procure the whole door and get it installed by their workmen. Certainly, it is not an elegant solution for the house owner.

 

The most immediate solution is to be able to fabricate this simple part quickly in less than 10 minutes to replace the broken part. With the part replaced, the sliding door is now functional again.

Updates for the month of July 2019

Every month, we will feature new contents for the website here.

Teleprompter Project

Teleprompter Project – A teleprompter is a device to help new-readers and course creators to speak naturally when on-screen. As we all know, it is not easy to speak in front of video cameras. Even teachers and course instructors who have a lot experience speaking to a class of students, ‘freeze’ when attempting to speak in front of video cameras. The invention of such a device greatly fills the need for many of these people. However, a commercially available teleprompter is a relatively expensive investment. Wannabe online instructors may find it expensive in view that their investments in these hard-wares may not yield the right return. Given its relatively simple design, many people attempt to build one instead of buying one, at least for the start. Consequently, many tried to make home-made teleprompters, many of which are made from card-boards and plywood.

Colour Sorting Machine Project

Colour Sorting Machine Project: Many machines are able to sort out items based on shapes, sizes, weights and, possibly texture. However, sorting by colour and smell accurately are near to impossible. The reason why colour is difficult to sort out is that there are so many colour combinations that we need to use numbers to represent them. (Can you imagine just a colour of red can have 255 shades of red colour and if we want to have a combination of 7 rainbows colours in different shades, how many possibilities do we get into?)

The FlyWheel Project

The flywheel project is a study project to evaluate how a dc motor can be used to drive big flywheel by controlling the speed and direction. The project made us of a very slow speed Arduino Uno microcontroller, DC motor(6RPM) and a motor driver (L298N), which can be used to drive 2 dc motors.

Challenges:   The main challenges are not in the electronics, but in the mechanical designs. To save weight as much as possible, there are no fasteners on the flywheel. (Fasteners are used only on the static platform to ensure stability of the system when in rotation.) The hub at the centre are built with very close tolerance to ensure that both the static and rotatable parts that are carried on the same shaft work according to their intended functions. All the rotating arms subtend from the centre are assembled together through proper fit mechanically.

Read Financial Statements as a Stock Investor

A lot of people see reading financial report as a chore. Many do not have patience, or simply do not have time, to read the financial reports. The first glance of the 200-pages report is good enough to put shareholders off, let alone going into the report details. In fact, quite a number of information can be picked up from the financial reports if one has the patience to look into them. One of the key elements in yearly or quarterly reports is the financial report. Together with the accompanying notes, financial reports form the bulk of the annual or quarterly reports. It has to be because company financial is the lifeline of a company.  ….<<Read More>>

Five steps to Stock Investing

Stock investing can be both an easy or an extremely difficult task. The reason is that the stock market moves so randomly that that it is almost impossible to predict the movements of the stock market, let alone the prices of individual stocks in the stock market. In a nutshell, a few factors can affect stock prices. First, there is company performance. Also, there are always macro-economic factors surrounding the stock.  Then there are other factors as well such as political, market sentiments and market players with different investing objectives and time-frame. ….<<Read More>>

Build yourself a financially formidable defense system

In the course of chasing for wealth, we often forgotten about the need for protecting ourselves. A person who is always on top of his personal finance will understand that protecting ourselves is just as important as growing our wealth. Apart from understanding some important financial numbers in our personal finance, we need to adopt proper defensive strategies. It is no point to earn a lot of money, but squander away through excessive means or through poor health. Simply put, we need to know numbers in personal finance. We need to know protection strategies like insurances and expenditures. Quite importantly, we need to have end-of-life planning too. …<<Read More>>

Investing for success: Grow your wealth

Apart from applying protection and defensive strategies, we need to invest as well. Just as the economists say – we have unlimited wants but we have limited means. We are always a consumer of some sort, from the time when we are born into this world to the time when we leave this world. Unfortunately, we do not have all the earning power for the whole period of time. Our earning life-stage is only between our mid-20s to our mid-60s, at best. In other words, it is only 40 years at most. And, very often, this stage is infested with a lot of disruptions, such as retrenchments, sickness, incapacitation or becoming a caregiver to family members. Even if we managed to sail smoothly in this life-stage, inflation compounding at just 2% per year is good enough to wipe us out financially. So, there is always a need to have some kind of passive incomes to help us….<<Read More>>
