#pi4

Hello ladies and gentlemen, welcome to my ongoing world of waffle. So as the title suggests a friend lent me a Raspberry Pi 3 with 1GB of RAM and a Raspberry Pi 4 with 4GB RAM.

Now in the past I have always been dismissive of the Raspberry Pi so they were lent to me to play with to see if using the items in question would change my perspective.

Well started off with the Pi3. Installed Raspberry Pi OS (Raspbian as it used to be known). It works fine if a little slow but that's to be expected given it only has 1MB of RAM. It will browse the web, but try and do anything beyond that and you start to see the slow down.

I did get the ZX Spectrum emulator Fuse working and providing you never got above double height video it worked alright. I managed to play TLL without too much stutter.

Installed RISC OS next which was interesting for all of about ten seconds. It didn't support the WiFi so I could not install any different software so that was that.

Looked at Retropie... Nice idea but unfortunately it's using RetroArch (the most annoying multi-emulator ever) so I quickly got out of that.

I have yet to find a core on Retroarch I can say yep that works without problems. So as soon as I saw that it was RetroArch. Oh dear well it was a nice thought.

Now I'm sure I am going to get people complaining that if you set Retroarch up correct it's fine. I don't doubt it but it's a faff to sort so it can take a run and jump.

Right having messed around with the Pi3 it was time to move onto the Pi4.

That's when I hit the wall. For some strange reason I was not getting a video output. Now remember this isn't my Raspberry Pi. I am borrowing them from a friend. I am quite concerned.

The adaptor he supplied as soon as I connect the HDMI to it, goes snap. Not good. So I connect up a micro HDMI to HDMI cable. Nothing.

Odd. I eventually get another adapter type and finally I get video. However if you straighten the cable the video cuts out.

I don't know if this is common but video works if it's pulling slightly to the right. I don't think this is common but as the saying goes when in Rome.

Raspbian works as it should and the extra ram is definitely noticed when typing stuff.

One of the things I installed on both versions was Focuswriter (a minimalist word processor). On the Pi3 you had to wait for it catch up when typing. It would normally get it but there was a delay before it appeared on screen.

On the Pi4 this delay seems to have gone thankfully which is to be expected given better processing power, more RAM.

Web browsing works but is still underpowered. However on the 4GB I can open more than one tab which the Pi3 could not.

Video playback is not great and for all they claim the Pi4 can do 4k. Not streaming it can't. It could just say manage 320p without it falling apart.

However that could equally be the fault of my internet as it is not exactly quick.

Audio playback was equally a bit choppy.

Part of me is suspicious due to the strange connection angle required maybe I'm not getting optimal signal here.

I moved on from Raspbian and attempted to get Manjaro ARM to work.

This was a fail. It ran through it's setup then on the reboot refused to start up into X. It just sat there looking dumb and would not accept any keyboard input.

Oh dear not a great start. Ok moving on I discovered a system called Twister OS.

Now it's a modified version of Raspbian but allows window theming, overclocking and seems to have several more basic programs.

Well it starts off fine. It can indeed be themed to look like Windows 95, Windows XP, Windows 7, Mac OS X (light and dark modes) and its own TwisterOS desktop.

They all change easily using the Twister themes and each time you have to restart but it's quick and responsive so not bad at all.

The overclock can be set manually or be set using the modes of on-demand or performance from the system tools menu.

Being it is a modified Raspbian install it can use all of the same programs so tested with Focuswriter.

It runs smoothly. Loaded Fuse the Spectrum emulator and it has no real issues. Then I try the challenge.

MAME is always a good test. I had ran it on the Pi3 before now and while things loaded it struggled with sound and frame rates were inconsistent.

Well it seems running under TwisterOS. MAME ran my test games of Frogger, R-Type, R-Type II and StarForce without issue. I did not even seem to have to switch it to performance which I thought I might but they all worked fine with no major slowdown.

So bonus points to the Pi4 it worked regarding basic emulation pretty well.

To be honest running the Pi4 with TwisterOS it really isn't bad. Obviously provided you don't intend to use it to stream video the Pi4 is definitely an improvement over the Pi3.

Now I admit the Raspberry Pi isn't aimed at me. Don't get me wrong it can emulate stuff, but the Pi is aimed at programming types or engineering people.

They will try and connect the Raspberry Pi to cameras to monitor birds, or connect to your doorbell be a monitoring device. Or sit and teach your kids how to program in BASIC using Scratch.

I don't have the patience for that sort of stuff or the skill as normally it involves soldering or programming neither of which I can be fussed about.

Is the Raspberry Pi a bad idea. Not at all I'm sure someone always finds ingenious ways to use one. Am I one of those people... nope.

Do I think I will ever invest in a Raspberry Pi. Answer probably not but now at least I can admit that the Pi4 is not as bad as I thought it was.

Now my experience is over I can return the Pi's to their owner forthwith. Job done...

Step to install Windows 10 on Raspberry Pi 4

With Windows 10 coming to ARM stages, for example, Qualcomm Snapdragon and Samsung Exynos, we realize that it’s conceivable to run Windows 10 with work area applications on ARM gadgets, including Raspberry Pi 4.

There are various approaches to introduce and run Windows 10 on a Raspberry Pi. Microsoft has consistently permitted clients to run “Windows 10 IoT”, which is likewise a form of…

前一陣子收到一份很實用很精美的聖誕禮物，剛好乎合我這陣子的需要。這是一部無線入耳式耳機，對於這陣子因為體格訓練實在是一個好好聲音導航。邊聽著歌邊跑步，實在是樂趣多多。

就讓我把聖誕禮物開箱，讓大家都一起分享我的喜悅。

這款無線入耳式耳機來自英國50多年歷史的頂級音響品牌Bowers & Wilkins (簡稱為B&W)，品牌以締造極致原音為名，讓用家能夠體現the highest form of sound。B&W的產品均可以主動降低噪音，其電池續航力亦相當高。

除了耳機之外，B&W還有具設計感及製造精密的家用揚聲器及客制化高性能汽車音響產品。品牌獲得來自世界各地錄音室和音樂家的讚譽，而且獲獎無數。品牌聲譽源於努力不懈追求最佳原音及無與倫比的音樂聆聽體驗。

打開產品的包裝，入面就是B&W的PI4主動降噪無線入耳式耳機。簡單的幾個按鈕：開關、連接手機藍芽、大細聲等等，很易就能上手。

細心的還提供幾個不同大細的耳塞，讓我可以更換一個最適合我耳型的耳塞。

還有一個蠻美的小袋子，可以袋著耳機，隨時拿出來用，能夠好好保存這個小小的耳機了。

才剛開箱，我就帶著它去跑步，PI4主動降噪無線入耳式耳機，擁有主動降噪功能，根據環境需要去除不必要的噪音。跑步的時候，有時候附近的車聲、歡呼聲、音樂聲會把我聽著的歌聲都蓋過。因此這部可以主動降噪功能的耳機，實在是幫了我一個大忙，讓我可以在自己選擇的氛圍下繼續跑跑跑。耳機以天然矽膠製成柔軟耳塞，配合各種耳道的運動型耳扣，加上耳機只有45g重，輕量舒適，因此跑步的時候，耳朵也不會有太大的負擔，而且很穩陣，跑多久也不會掉下來。這是我這一陣子用過最好的運動耳機。

再者，這個耳機單次充滿電可長達10小時不間斷播放，15分鐘就能快速充電，可獲得3個小時的音頻播放，基本上有時候有出門前充電15分鐘，就足夠我用上三小時，很快捷很方便。順帶一提。耳筒的兩側是磁性夾來的，只要取下耳機，音樂就會自動暫停，再次鬆開的話，音樂就會從上次停止的地方再播放。

還有一點，平日我有點寒背，帶著這個耳機跑步的時候，耳機總是撞到鎖骨。要是整個人企直的時候，就沒有這個問題，相信這個耳機是用來更正我點點寒背問題的，讓我在跑步的時候，也能站直身體，養成良好的跑步姿勢。
