My personal blog about stuffs!
I have been going through the Beginning Arduino text book to learn a bit about this popular microcontroller. I have these various components from the starter kit that I purchased last year during the pandemic lockdown and taking my time to learn about it. During this long weekend holiday, I decided to give the dot …8×8 Dot Matrix Pin Header Configuration 1088BS first appeared on Jan Leow.
My earlier post about super multi-boot using Linux GRUB2 as my main boot loader and menu selection had been fun to do! There were also some tricky issues such as some OS need to be installed first before Linux and other OS could be installed. Now we come to the issue of those Linux OS that could not automatically be detected by way of issuing terminal command ‘update-grub’ and had to be
SliTaz Linux is really small! As a super lightweight Linux distro, the compressed ISO form takes up about 50MB. It was mentioned in the SliTaz website that the decompressed root file system will take up 100MB. A quick check with my install, the storage used up so far was about 60MB. There are a number of SliTaz ISO image flavours to choose. However for my case, I had success with the rolling
Porteus is a super lightweight Linux operating system taking up about 300MB of storage space. It uses a squashed format for storing its core files, and will decompress when you boot. It also uses a modular approach whereby you install pre-compiled packages as opposed to the standard Linux using package manager. Because it is also portable, it is easy to install into any existing Linux
#ArduinoProject #UltrasoundDistanceSensors with #LCDdisplay16x2
I’ve been planning to try this out for quite sometime. First time I could’t do it as the LCD display pin headers needed to be soldered and I didn’t know how to do it. So no choice but to buy myself another one with pre-soldered header from #Cytron.
After assembling, the display spewed out some alien language readout! 👽 Took me several hours to troubleshoot it before getting it right! Turned out to be some mis-wiring. But all is good as I get to learn how the code worked and made some modification to it too. My next idea is to add on a beeper for objects that gets too near. 😁 Beep! (at Petaling Jaya, Malaysia)
#RainingDay it’s nice to have 🌧️☔ rain! Cools down the current heatwave. Nice to go for a snooze 😴. Unfortunately it’s a WFH working day. So no lazing about! 🧑🏫🧑💻😁 (at Petaling Jaya, Malaysia)
Haiku is the current continuation of the old discontinued BeOS system. I had the BeOS installation CD a long time ago and played with it a little when it came out. It didn’t catch on and sort of fizzled out. But lived on as an open-sourced Haiku. I was surprised to find Haiku as a form of BeOS still hanging around the internet. I have been curious about the various OS that have been developed
Kolibri OS is another alternative operating system that is non-Windows, non-Linux. It is a super lightweight OS that was branched off from Menuet OS from 2004. It uses very little storage space and very light on hardware resources. I got intrigued with it when I happened to bump into a YouTube video showing how super fast it booted up! Until now I still haven’t got a chance to try out Menuet OS
Having cleaned up several of my old PCs, I’ve decided to embark on my next project. To make a super multi-boot OS system with Linux, DOS, Windows XP and alternate operating systems. Dual-booting is fairly easy, but multi-booting with 10 OSes, now that would be a feat! In order to cram in so many OS, some prior preparation would be needed. Since these are old PCs with Pentium 4, Dual-Core and
During my preparation for a super multiboot computer, I needed to know how much hard disk space to allocate for the various Linux, DOS/Windows and alternate operating systems. These were usually easy to check by visiting each of the distros websites. Anyway, I took some gparted partition manager screenshot of my hard disk, hopefully this would give a fair idea of how much space each distro used
Puppy Linux is one of the most handy of the super light linux and considered my goto distro whenever I need to make changes, edit files, and copying files or moving files between distros and between partitions. It dispenses with the need to key in sudo privileges because it is already considered as root and has no issue whatsoever when I need to access another Linux partition. I was using the
I first learned about LibreElec when I got my Raspberry Pi 4. Having played around with it to watch some movies and connect to Netflix, YouTube and Spotify in the little RPi SBC, I was thinking of installing it on my spare old PC. LibreElec has a simple Linux shell making it very lightweight. It just concentrates on being a media player by running Kodi fully. Heading over to the LibreElec
#YeeSang #CNY2021 otherwise known as #ProsperityToss is a Malaysian/Singaporean dish invention to usher in the new year. It’s a jovial dish with everyone holding a chopstick tossing the food up high and saying words for a better year, wealth, health and happiness! 🤗
Also make a big mess on the table, an indication of the happy fun mood of Chinese New Year 🥳 celebration! #GongXiFaChai!
#Arduino #ArduinoBasics #LEDChaser Lights Project
I’m still plodding along my Arduino learning tutorial. Taking a break from fiddling with Linux on my old PCs; this CNY, I’ve decided to try out the LED Chaser Lights ala Knight Rider. I didn’t have enough red LEDs so I mixed it with the green and yellow LEDs that came with my starter kit. Copied the code and uploaded it and voila, there it goes! I was bit tired to study the code; perhaps later. This time I have to use up quite a fair number of jumper wires and 1k resistors. Next lesson was to add on the potentimeter to change the speed of the LED chaser lights. (at Malaysia)
My old Acer Aspire Switch 10 had been running slow for many years ever since my bad attempt at upgrading it to Windows 10 and reverting it back to Windows 8.1. The lag was rather trying and I had to be rather patient whenever I used it. I failed to install Linux for the past …How to Install Linux for Acer Aspire Switch 10 with EFI32bit boot first appeared on Jan Leow.
