Inexpensive Mini PC Beelink Z83II to replace a noisy system unit

Inexpensive Mini PC Beelink Z83II to replace a noisy system unit

We open the box itself, we see the instructions and the Mini PC there This is my first review of such a Mini PC, a review will be difficult to write but wildly interesting. On the official website of any information about this Mini PC. Sent in such a dense and unsightly box It would have been better, of course, to add more RAM, but for some reason the manufacturer did not do this. The main characteristics are indicated on the back of the box Although it’s also quite possible to play the game of 2007-2008, you can’t count on more powerful ones. Special power was not required, since no one would play toys, mainly surfing the Internet and watching movies. For a long time I wanted an inexpensive Mini PC to replace an old and noisy system unit at work, which was used mainly for the Internet. Mini PC is made of plastic, matte on top, glossy on the sides, which collects fingers. In this case, this is an updated version of the Z83 Mini PC, but on a more powerful Intel Atom-X5 Z8350 processor, with an Intel HD Graphics 400 graphics processor. Since the long-awaited gadget was in the hands. Softtouch coating on the bottom, so that it apparently does not slip if used without mounting behind the monitor. Complete set: power supply 12V, 2A, monitor mount 100×100/75×75 with bolts, two HDMI cables (short and long) and instructions

Smoke detector from Xiaomi

The product is delivered in a box of traditional Xiaomi design
If you look inside, you can see the lattice of the labyrinth of the smoke chamber But
for the device to fully participate in scenarios with other gadgets from the smart home system and receive notifications remotely, you still have to purchase a gateway. The sensor is compact enough to fit in the palm of your hand.
The platform is attached to the ceiling either the wall with dowels or

The IR reflects off the smoke particles in the chamber directly into the photodiode. After that, many more devices appeared in the application. The device can also notify the presence of smoke visually – using a flashing LED. After that, the new sensor appears in the list of your devices.
Slots for the latches on the side < br />According to information from the comments to the review on the old model of the detector, the principle of operation of the sensor is as follows: “In this type, optical sensors are used on an IR emitting LED and a photodetector of the photodiode type.
In the center of the body, the air intake of the smoke chamber protrudes If there are no smoke particles, then the rays are not reflected into the photodiode. Dimensions: 9.5 cm in diameter and 4 cm in height.
as well as everything in Chinese At the very top is the detector’s mounting pad. Review published in accordance with clause 18 of the Rules The device is powered by one lithium battery of exotic format CR17450 with a voltage of 3 V.
Almost everything on the box is written in hieroglyphs, apparently the product is intended for the Chinese market
I only found this picture on the net. The main areas of activity are aerospace equipment, technologies for the operation of buildings and industrial facilities, automotive equipment, turbochargers. To pair, press the button several times until the indicator light starts flashing green
back cover and BT 5.0 communication protocol instead of Zigbee, which allows you to use the new smoke detector without a gateway, directly with the MiHome app on your phone. It was not possible to roll up the modified application from above.
It has such a design The new Xiaomi smoke detector called Smoke Sense Guard 2021 is certified in China as a fire protection product. The lower cover of the sensor housing, which is also the mounting platform, has two holes for the complete screws and slots for the clamps
The old application had to be deleted and the mod from Vevs installed on the new one. The manufacturer claims that it should last for 5 years of continuous operation. We set fire to a match and fumigate the smoke chamber
The correct option for this Mi Smoke sensor Detector.
At the bottom of the main window there is an item for creating scenarios involving the device and integrating it with others in the house according to the “If” condition < br /> The main feature of this detector is that it is part of a smart home and is able to remotely notify about the appearance of smoke in the room by sending a notification to the phone. However, there is only a Bluetooth logo on the box.
I found on a Russian-language instruction for the old version of the detector, since the differences between them are minimal, I will use it. But here everything turned out to be not so simple. This allows you to connect the sensor directly to the phone in the MiHome app, and not through the Zigbee gateway as before. I thought that the item after the battery is the sensor sensitivity setting, but clicking on it does nothing, apparently this is the battery charge level.
After that, you can select the location of the sensor, give it a different name and share access for other family members. Inside the box is a modular shipping package.
What is the way out? Either change the region to China, or install a modified MiHome application from Vevs. The direction of equipment automation is occupied by the Honeywell Enterprise Buildings Integrator (EBI) group of companies, the main applications are building management (providing traditional building management systems: heating, ventilation and air conditioning, lighting and electricity systems) and building security (access systems, security, video surveillance, photo identification , smoke and fire detection, sprinkler control and emergency evacuation). Judging by the data from the page with the product version 5.0.
The delivery set consists of a mounting kit, a removable back cover, a Smoke Sense Guard 2021 detector, a battery and instructions If Xiaomi needs no introduction, Honeywell deserves a few words.
I absolutely did not want this, since the application already paired a vacuum cleaner with a rendered apartment map and verified restricted areas on it.
The device, like a conventional smoke detector, is controlled by a single oblong button with a LED The device is equipped with a smoke detector from the American company Honeywell and a built-in sound alarm with a volume above 80 dB.
After a couple of seconds, the sensor squealed piercingly and the red backlight lit up This experience gives hope that the joint product with Xiaomi – Smoke Sense Guard 2021 is not a fun trinket from the Xiaomi smart home ecosystem, but
a full-fledged fire-fighting device that can be trusted with security functions. A red warning window appears on the application screen, and the logs are written in Chinese I consider the device useful, although I hope I will not have to verify this in practice. The company was founded in 1906 in Minneapolis. The new version, unlike the old one, works via Bluetooth, and not via the Zigbee protocol. The product was provided for writing a review by the store.
But it makes little sense to purchase such a gadget as a simple sound detector, since analogues are several times cheaper. With promo code BGc13762 Xiaomi smoke detector price
There are many holes around the perimeter of the air intake chamber, probably for a sound detector
Then the application will load the plug-in for configuring and controlling the smoke sensor.
Let’s check how the detector works. But in the sensors section, there were already 2 smoke detectors: Mi Smart Smoke Detector and Mi Smoke Detector The first option did not suit me, since the application notified that after changing the server, paired devices will be permanently deleted. Here it is recommended to install the sensor on the ceiling at a distance of at least 50 cm from the wall or on an inclined plane of no more than 45 degrees and also with an indent of at least 50 cm from the edge.
Pairing went without
problems It is also not allowed near the window, the distance should be 1.5 m from the window and there are no recommendations regarding installation on the wall. Weight 140 grams. Xiaomi Gateway 3 is suitable for this sensor.
The mounting kit consists of two small dowels with screws and double-sided adhesive tape < br /> As I expected, the detector is intended for the Chinese market and in my MiHome application with the Russia region installed, this sensor simply does not exist.
In the sensor settings, the information is partially in Chinese. It is an American corporation producing electronic control and automation systems I planned to put the sensor on the ceiling above the stove, but the instructions for the old version of the sensor do not recommend doing this.
Started from the first one and, as always, did not guess correctly

Smoke detector from Xiaomi

If the detector is not turned off, then the sound will grow and grow until it is completely unbearable. I don’t have a gateway yet and I will use the application. I first looked for a smoke detector in the "Alarms" section, but it was not there. The background changes to red when the sensor is triggered. Placed at an angle to each other in a dark chamber like a light maze. The device is part of the Xiaomi smart home system and integrates with other products of the Mi Home ecosystem.
In the announcements for the product, I met information that The new detector supports Bluetooth 4.2 and Zigbee 1.2 wireless technologies.

“Automobile” terminals. Replenishing…

S – thickness, where through a slash – this is when in dads the actual part that is inserted into the mother is two-layer. Unless the elongated "daddies" pleasantly surprised, and now you can take them straight without breaking off. The terminals are not magnetic. Well, the following came to me: drop on male-female connection at 5A current: for 2.8mm 6mV (1.2mΩ) ) However, all "dads" have noticeably thicker metal than the corresponding "mothers" for 6.3mm 4mV (0.8mΩ) It is better to buy normal thick metal terminals either in electrical stores or order online, but from well-known manufacturers in order to see the declared characteristics in advance. In general, four-way terminals can be taken, but, I repeat, for non-critical applications. I started to run out of terminals, I decided to buy some.
I shopped in several places. for 4.8mm 4.8mV (0.96mΩ)
The sizes are like this.

"Automobile" terminals. UPD: asked to measure the resistance of the contacts. In particular, I ordered sets of dad and mom of 100 pieces in sizes 2.8 / 4.8 /6.3mm here, long dads 6.3 with a lock here, moms 6.3 with a lock here. Well, I want to immediately draw your attention to the fact that in this case the metal is usually thin, although it is quite rigid, but these are definitely terminals for non-critical applications, for any low current and small sections.

Charcoal powder for teeth whitening.

Packaging. The product was provided for writing a review by the store. Everything is washed off quite easily, but longer than we would like, until you wash yourself, clean the sink and everything next to it takes a lot of time. Charcoal in the form of powder, no smell. I brush my teeth like almost everything with paste and floss, although out of curiosity I tried to use tooth powders, mouthwash, and even the eastern version of sivak, but I learned that some brush their teeth with charcoal quite recently, and at the same time they use the usual one activated from a pharmacy, by the way, I don’t think that there is a big difference between them, since activated like this one is considered organic, there may be differences in the type of burnt wood. Of course, you can study, but it takes many times more time than from ordinary pasta. There is no unpleasant taste or smell during cleaning, the feeling is something like brushing with tooth powder, until you look at yourself in the mirror everything is fine) lips, chin, hands are all black. Hello everyone, one store on Aliexpres offered to provide charcoal tooth powder, which, according to assurances, perfectly whitens teeth, could not resist and, out of curiosity, decided to try and talk about a new way to make a Hollywood smile. It’s too early to talk about the effect, and it would be more correct to add a photo in the “before-after” style, but there is no device capable of conveying the color of the teeth well and truthfully, after the first cleaning, surprisingly, but not a big effect was, the teeth became a little whiter than before, maybe it’s self-deception or it just seems to me, I don’t know. Review published in accordance with clause 18 of the Rules
I advise you to purchase a separate brush, since it turns black from coal and is not completely washed, you can take a special one in the kit, but it costs a lot and it’s not a fact that it will be better than a regular store one. In fact, this is all I wanted to write, not much has been said about the most important thing “how to clean”, but there’s nothing to say, but it cleans, but there is an effect, will it replace the paste? there is little chance, this thing is not practical, and it is not suitable for everyday use for me, maybe once a week I will undergo prophylaxis with it, I think it definitely does not harm (although it is better to find out the opinion of the dentist), but the rest is up to you.

Irrigator Conair Interplak WJ8 after two years of use

So be careful! Interestingly, this model is not available on the company’s websites, maybe it is no longer produced? Verdict: The thing is worth the money, even more than.

Irrigator Conair Interplak WJ8 after two years of use

Attention, the store disappeared from Ali for two years, and sellers with a similar product were not found. Therefore, the link is only to the picture of the order. For oral care, boiled water at room temperature and special solutions recommended
specialists. Only a picture of the order remained. The gums are not massaged. This faucet has never been used at all. At maximum pressure, the tank is emptied in about a minute. Outwardly they differ in plastic color: blue for 110V, green for 220V.

rinsed with water at the same time. tube. Its purpose is apparently in the use of various liquids in different compartments, such as rinse aid and plain water. Yes, and this model is no longer sold on Ali, although if you wish, you can find it on third-party resources, such as Ebay It is not recommended to use tap water, as the dangerous bacteria contained in it can get on the mucous membranes, and then oral care will not have the desired effect. Double 2×250 ml removable reservoir (although if filled to the brim it will be 2×300 ml) with compartment switching. Dentists recommend using the irrigator once a day. With increasing pressure, shocks are less frequent, but more powerful. A few more photos. Unfortunately, the seller from whom I took this device for two years disappeared on the site. The tube is twisted into a spiral, the length of the tube in the working position is 80 cm, the maximum length is 100 cm. Its additional function is a deep massage of the gums in order to improve blood circulation and active tissue regeneration.
The use of the device is contraindicated in the acute stage of periodontal disease, as well as in preschool children who still lack motor skills. Now let’s move on to the actual review. Although of course this is all subjective, and the maximum will seem small to someone. The peculiarity of the irrigator is that it cleans the oral cavity with the help of a powerful pressure of a water jet, which effectively flushes out plaque that a toothbrush could not cope with.
Why Conair and not Waterpik? Speaking of pressure.
Although Conair is also quite a company, anyone who is interested can read more on the Internet. And gradually wound up to the maximum, in vain of course. Irrigator use – indications Now the krutilka more often stands in the middle position, that’s enough for me. BUT, when I was looking for reviews on this irrigator, I came across information that the tank switch sometimes fails. Water comes in pulsating shocks. To begin with, I note that there are two versions of this irrigator model, with different power standards – WJ8 for 110V and WJ8K for 220V.
At first, some public information from the Internet – what is this thing and what it is eaten with. – pregnant women, since during pregnancy, especially careful oral hygiene is required in order to prevent the formation of inflammation, tartar, caries, and periodontal disease; suffering from periodontal disease in the early stages; Maybe I didn’t search correctly, or not there? Therefore, I immediately put it in the middle position: water flows simultaneously from two compartments, and did not touch it for more than two years. Why is it necessary to use an irrigator? It should be noted that the irrigator is not an alternative to a toothbrush. However, plaque and food debris tend to accumulate in hard-to-reach places such as interdental spaces and periodontal pockets. The rubber on the tips of the periodontal nozzles has only slightly darkened, which can be seen in the photo. More on this below.
Water consumption directly depends on the set pressure mode. – those who have installed braces, veneers, crowns, implants – the use of this device greatly facilitates the care of orthodontic systems; The fact is that regular use of a toothbrush and dental floss provides only a superficial cleanliness of the teeth and gums.
In total, for two years, with careful handling, nothing burned out, nothing broke. Although the old model WJ7 is available on the site and for sale in various stores, for example here. Or maybe I’m just looking in the wrong place? I must say right away that I didn’t try to look for Tao, because I don’t know how. Although quite a lot of attention is currently paid to oral hygiene, not everyone is familiar with such an issue as the use of an irrigator. This review is not a new purchase, unpacking and performance test, but an opinion on the operation of a Chinese irrigator after two years of use. Use of the irrigator – features At the bottom of the tank there is a valve for supplying water to the irrigator. When the tank is removed from the body, the valve automatically closes. During the first use, I first tried it at a low level, and something was not impressive. To each his own, everyone has different taste preferences and income levels. – patients with hormonal disorders. Actually, the use of the irrigator is carried out in combination with other oral hygiene devices. On the handle of the irrigator there is a button to temporarily shut off the flow of water for ease of use. Mostly on the Internet there are reviews on WaterPik devices, so I wanted to fill this gap. There is a capacity switch on the side. I do NOT recommend using this button at the set maximum pressure, judging by the sound the pump starts to work with an overload, so you can burn it.
And their untimely removal leads to the appearance and reproduction of pathogenic bacteria and, as a result, the occurrence of caries, stomatitis, gingivitis, periodontitis and other rather dangerous and unpleasant diseases. The use of an irrigator is especially relevant for: This device removes only food debris and fresh plaque and does not cope with pigmented and old plaque. The plastic of the body and nozzles did not change color, and did not crack. I beat my gums, tester, damn it.

Oimaster MR-6203 dock for 2.5″ and 3.5″ drives in 5.25″ bay

The dock is designed for installation in a free 5.25" bay of a PC case. This is slightly longer than the latest models of 5.25" optical drives, so in compact enclosures may present some difficulties.
And for a 3.5" drive, they installed TC4953 – a dual MOSFET for 30V, 5A package SOIC-8:
The quality of board cleaning from flux residues can be described as average. Indication and power control board, rear view: There are transistor keys for this – the 5V line for a 2.5" drive is handled by a key in the SOT23 package:
If you pull them further, the lever system pushes the drives out of the case. The product was provided for writing a review by the store. < br />The length of the flexible part of the cables outside the housing is 400 mm. On its front panel there are two bays for placing drives, closed with hinged covers with the ability to lock with a key, two power switches, two power indication eyes/ activity and two USB 3.0 connectors.The color of the front panel is black, no options. Review published in accordance with clause 18 of the Rules
The package arrived in a simple corrugated cardboard box. The same, front view: For the operator, this looks like a change in the brightness of the indicators. The device is a passive adapter, so the data transfer rate does not decrease. The plastic covers of the compartments were somewhat upset – I think that metal ones can be made for this price.

Oimaster MR-6203 dock for 2.5" and 3.5" drives in 5.25" bay

One solution to this problem is the eSATApd interface, the other is an embedded dock.
By removing one screw, the USB 3.0 cables can be removed from the case for use elsewhere: Conclusion: The product is quite specific and highly specialized, but it has its own niche of application and will find a buyer.
There are 4 blue SMD LEDs here.
It provides the ability to turn off the power separately
removed drive without removing it, which can be useful to reduce its noise level and wear. 3" is quite heavy, so it does not move out much, but enough to grab it:
The drive is removed, the front panel is removed:
The cover is open, the ejector mechanism has worked MOD:
We unscrew 8 screws and the metal cover can be removed:
The drive ejection levers are also plastic.USB 3.0 cables just go through the case also becomes clear why this box requires two cables at once Two glow constantly when power is applied, two more light up when drives are active.
We cut open the adhesive tape that prevents the box from opening ahead of time, flip the lid and see the dock sandwiched in polyethylene foam inserts along with accessories.
The ventilation of the slots here is somewhat arbitrary, because there are no fans, and the slots from below do not provide airflow to the sides of the 3.5" drive: /> There are two sets of SATA connectors on the rear panel, ventilation slots, and USB 3.0 cables coming out of the case. But you still need to work with 3.5" and 2.5" drives, sometimes you need to change them on the go and it’s not always possible to use a USB adapter for this.
The length of the dock body is 200 mm. Welcome to cat. The switches are small-sized, since they do not directly switch the operating current of the drives.
A 2.5" already pops out half the length and more: 2.5" drive inserted, cover closed: No typography, no postal packages – just a shipping address stuck on cardboard and that’s it. That’s it, we now take a closer look and consider.
do not budge:
The dock comes with two SATA cables, two keys to lock the bays, screws for installation in the case, an instruction booklet and a warranty card. In our time, M.2 drives are firmly established in computers, installed directly on the motherboard and do not require a separate place in the case.
The covers are plastic, so there is a sticker on top of the dock body with a reminder how to pull them correctly:
