Two shields and two dead drives was enough for me to understand that everything Suptronics does of shields for uninterruptible power supply for the Raspberry Pi is hellish shit. Two x705 and x725 boards are constantly in the battery charge state, after one day they cut off the power and discharged the battery to zero, thus killing two USB drives. It is not clear why the infinite row has not faced Suptronics yet, on the product page on their wiki there are a lot of comments “mine does not work”. для x705, для x725,
Old Technologies – eMule: Installing the aMule p2p client on Raspberry Pi!
At the time of the massive promotional company of Torrents, when every teapot told about it, the eMule users laughed – why do you have to register if a true p2p works without all that by nature, that is, a priori! Now, of course, with the development of technology, the financial need (especially in Russia) in p2p methods of transferring information has disappeared, so eMule is of interest only to IT-archaeologists and marketers who insert it into their products to increase its functionality.(like Synology).
Khadas Edge-V MAX as Ubuntu Desktop PC!
That’s it, the latest attempt to find a use for Khadas Edge-V MAX from the most pretentious, most expensive and most funny Chinese manufacturer. Guys are really funny – they say this is the most powerful miniPC for Android TV, but they haven’t certifide it with Google, which means Netflix won’t work and etc. They sell the official case for Khadas Edge MAX, but they do not warn that it will have to be finalized! All kinds of additional options: it was possible to do something with them, but the battery works only on Android, who needs an Android like that: a cooler, it’s good only if it doesn’t scream louder than the TV, but this is not about the Khadas official cooler 🙂 I already described this in detail here ¡Review of Edge-V MAX as a TV Box for Netflix! and here Khadas Edge-V MAX: Excellent and Terrible, review!!
I will try to use Khadas Edge MAX as a desktop. It does not work with HDMI > VGA adapter, so you need a monitor with speakers or a TV with HDMI.
How to automatically turn on PC fans with Arduino according to temperature!
Previously, I made software solution to turn the fans on/off via a relay on the Arduino upon entering the operating system. It works on Ubuntu (off), it worked on Windows via PowerShell (on), but now it doesn’t want to work anymore … so why should we bind to the OS if we can hang a temperature sensor on the Arduino?
The Arduino will monitor the temperature itself and turn on additional fans. Using the serial port, it will be possible to turn on/off the fans manually, turn on/off the automatic mode, observe the temperature.
Home server on Raspberry Pi 4 with NVMe, RTC, UPS in a DIY case!
CAUTION: From my experience, it turns out that if you install the operating system on USB and boot Raspberry OS from it, an accidental shutdown very quickly kills the USB disk, on the second or third time!
that’s how died
1Gb noname mSATA on SupTronics X856 v1.0
256Gb KingSpec M.2 NVMe on Blueendless SSD M2 PCIe
x725fro no reaone shut down after 30-60 hours of operation power ans starts to discharge batterys.
What a home server needs is a fault tolerant power supply, a large and fast disk, good cooling, small size, mobility, well, to put it where there is at least power! This is what I will do: power supply through the X725 with 18650 batteries, the NVMe disk is excessively fast for USB3, the best cooling! And a sleek little case – there are no universal Raspberry pi cases, for all the stuffing, but you can take a standard one and tweak it!
How to turn on additional fans on PC via Arduino!
I played Assassin’s Creed Odyssey and again freaked out how the PC is getting hot! I have Windows exclusively for games, so I decided to turn on additional fans there, via Arduino, and in Ubuntu, where I enjoy “silence”, I will automatically turn them off! I will communicate with Arduino through the Serila port!

Installing http2 site on cloude(VPS) hosting HETZNER in Germany!
It is time to move on, towards to progress, towards to Europe! I don’t expect everything to go well there, but I am sure that the best technologies and specialists are already there; therefore, European hosting is cheaper, more powerful and more technologically advanced than Russian! Germany, if I am correctly mistaken, is the largest data center in Europe, where a huge digital infrastructure was built up for the World Cup.
Why HETZNER – I did not have much time to choose, I was relying on the images on the site, those words are not even known by Russian hosting companies – AMD Epyc, NVme and really “unique prices”.
How to choose a silent fan position for Ryzen 7 in ITX case!
Why AMD Wraith Prism cooler is terrible should be obvious by now, but you have to understand and measure it! They keep selling it, they even made the LED light on it, and not just any light but configurable via USB, why if even the cheapest tower cooler is better than it! They are trying to sell it for $20 a second hand, although the difference between an oem version and a box version where it comes bundled with a processor is much less, and sometimes box is cheaper than an oem!
My hardware
Processor: AMD Ryzen 7 3700x – 65W TDP, there are also a 7 3800x it is ten percent faster, but in watts it is half that much – 105 watts; my attitude towards watts is like that – they couldn’t do it smartly faster so that’s why they raise voltages adding cooling and durability issues, but they all do it! After 95 degrees, the frequency starts to drop, so you have to cool it down befor 94 degrees.
How to fix bugs in Ubuntu 20.04 LTS after installation + all necessary programs!
I am actually an Ubuntu fan! This is a system that once configured, works for years, so long that you forget the scare after installation and the adjustments that need to be made! To begin, I download the image Ubuntu 20.04.1 LTS the installation is usual without tricks; be sure to check the boxes to download and install third party software!

How to make a new WordPress website on VPS with nginx, MySQL, Letsencrypt!
First, you need to buy a domain ( name .com – name second-level domain in the zone com) from any Domain Registrar, not an intermediary, by buing it you must become it domain administrator! Previously, in the days of the savage squatters, the best names were already taken and they extorted money for them. But these dark times are now over, domain registrars are officially doing the same thing: all the best names have already been captured, and when you try to buy them, they say this is a VIP domain or auction domain, which means thay will sell it only when you pay a lot of money. The rest of the domain names of the second level have a stable purchase and renewal price, different in different areas.
