Black Friday

No Comments Uncategorized

During previous Black Fridays I have bought a few stuff including notebooks, Chromebook, RAM, micro sd cards and VPSs… This year tried to order the Eco series dedicated server on OVH https://www.ovhcloud.com/. In the end got a KS-LE-2:

No luck in getting a free upgrade as per the OVH lottery just others get. Although IPMI is included in the server, setting up an environment to run a Java applet has proven to be quite challenging. Oracle has changed its licensing, making Oracle Java unavailable for free in commercial environments, while OpenJDK does not support applets. Additionally, I have found that the applet always crashes when attempting to mount an ISO, which forces me to install the server using the templates provided by OVH.

The installation process was almost seamless, requiring just a few clicks. However, my first attempt hung midway, prompting a technician to intervene and update the BIOS settings. For my second attempt, I tried installing Hyper-V Server 2019, which went smoothly, but I faced issues managing it via Hyper-V Manager over the Internet. Additionally, I encountered dynamic disk limitations, restricting to only two disks for mirroring the system volume. As a result, I decided to reinstall the server using the Proxmox Virtual Environment 8 template:

I must admit that Proxmox has a pretty neat GUI and creating VM is just easy using the wizard! Here is the YABS result:

A small model

No Comments Uncategorized

Recenty bought a small nanoblock clone robot that looks like Gundam RX78-2 from Taobao for just HKD 4.12:

The package was a bit squashed as expected:

Here are the materials inside:

Assembling took around 30 minutes with a final product:

Sudden change to VPS

No Comments

The low end VPS powering this blog got a sudden migration to then trendy Ryzen platform…. The VPS was pretty unstable and slow during the past few days, perhaps due to some kinds of noisy neighbors? Anyway it seems to be back to normal now….

A new case for the pi

No Comments

The pi was an amazing little device. However the original plastic case is rather limited in air ventilation, viewing a HD video on Netflix could easily makes it overheated to have the CPU throttled! Having no choices but putting the pi into a new case for daily desktop use…

There were so many cases on TaoBao and here is a cheap one I bought for just around HKD 33.

The package contaiing the metal case, fan and head sinks.
The pi inside the case with a fan installed, connected to +5v and GND.
The completed case with the fan.

The whole assembly process took around 10 minutes and I got the pi running with the fan in the new case. However the fan was really noisy and I suspect the vibration of the case made it even louder! So anohter few minutes in removing the fan in favour for a quiet fanless pi!

The fan was found to be really noisy! Removed it at the end.

A tiny device for WFH use

No Comments

Due to the COVID-19 pandemic, WFH (Worf From Home) becomes a new trend over the globe. The desktop I had been using was in fact an aging HTPC, the onboard sound was already broken and it would not superise me if it would fail any time soon….

As a cheap desktop replacement, I decided to try to recently Rapsberry Pi 4. It just got 2 days to have the package deliveried to me from a local reseller.

The box delivered by a local courier.

The package contains a 8GB Pi 4, case, heat sinks, PSU, 128G micro sd, card reader and a micro HDMI cable. Pretty neat as a tiny computer.

The items included in the package: pi 4B, case, heat sinks, PSU, micro sd, card reader and a micro HDMI to HDMI cable.

Assembled the unit took only a few minutes, that is a piece of cake.

The pi with heat sinks installed inside the plastic case.

Finally the finished unit in operation.

A new start

A fresh start

This is the first entry of the blog, also marked a start of the year 2021. I created this blog as a documentary of what I would like to build at my spare time…

This first item built is this blog deployed on a low end VPS:
