The look of quiet Microprocessor class

This photo was taken at noon on 8 January 2025, during the Microprocessor class. The students were unusually quiet, as they typically only exhibit this level of silence during test sessions.

That day, I was giving a briefing on the SDK V4 board, which was the first design using the STM32 microprocessor. The lecturer had asked me to brief the students before distributing the SDK V4 PCB boards and components. However, I requested to hand out the hardware first, and this sequence worked well. One group even noticed that I had forgotten to include a voltage regulator in their set, indicating they were paying close attention to the briefing and thoroughly inspecting their hardware.

I had divided the components into nine sets, and on that day, I only distributed three of them.

Overall, it was a productive class, and I hope the students enjoyed learning about PCB assembly.

The pretty look of blooming melur jawa@jambak flowers

This is taken on the noon of 8 January 2025. After microprocessor class. I managed to harvest 4 stalks of melur jawa@jambak flowers. After last week harvest 2 stalks of them. As yesterday,  I counted there is more than 22 blooming stalks of melur jawa@jambak flowers.

The pretty 4 stalks of blooming melur jawa@jambak flowers.

The initial 2 stalks of melur jawa@jambak flowers.

I have informed few friends to self harvest the melur jawa@jambak flowers. Since this month it is 2 times output than normal.

For this one, I put it inside vecad lab pantry. So it will have good fragrant melur jawa@jambak flower smell.

Until then, have fun in harvesting melur jawa@jambak flowers.

First harvest for year 2025=pisang raja (banana) fruits

This was taken on the morning of 12 January 2025. When I successfully harvested my ripe, yellowing pisang raja (banana) fruits. 

First layer/comb (sisir/sikat) = 12 pisang raja (banana) fruits. 

Second layer/comb (sisir/sikat) = 10 pisang raja (banana) fruits. 

Third layer/comb (sisir/sikat) = 10 pisang raja (banana) fruits. 

Fourth layer/comb (sisir/sikat) = 12 pisang raja (banana) fruits. 

Fifth layer/comb (sisir/sikat) = 12 pisang raja (banana) fruits. 

I used only three tools for the process: a serrated steak knife, a 12-inch saw, and a hoe (tajak). It took me 45 minutes to complete the harvest and clean up afterward. Just as I finished, the rain began to drizzle.

In the evening, I have to reply to questions from student of Microprocessor class. As they was eager to finished up the given components to be assembled on SDK V4 board. Basically my weekend is more like working from home. 

Until then, stay safe while harvesting your pisang raja (banana) fruits. 

Sorting components for SDK V4 PCB board

This was taken at noon on 7 January 2025, when I received help from a group of students from the Microprocessor class to sort the components for the SDK V4 PCB board. The task took 3 hours and 30 minutes to complete due to my detailed and meticulous sorting method. I prefer organizing the components thoroughly to ensure students don’t need to ask me which parts are for specific soldering tasks. For example, I have grouped the needed components for power supply part on the SDK V4 PCB board. Which I have also make the presentation slide on its assembly. 

I had to adopt this approach as I am currently tied up with finalizing my thesis corrections and managing other work and tasks. I am truly grateful for the assistance from these three students—it made a significant difference.

Close up on the components arranged by group. This is for Group 2 (power supply). For Group 1 is the Black Pill STM32F411 board set.

Until then, have fun in sorting components for your PCB board assembly.
