The DELL U2410 on the last computer has been used since the beginning of 2009. It has not been damaged. Recently, the hand-torn device was trying to tear off the reflective film. As a result, the substrate was destroyed and the substrate was thrown away. Seeing the German website's 2715K is particularly cheap, 722 euros, equivalent to more than 5,000, than the original U2410 will also be more than 2,000 expensive, buy an iphone but also 5,000 it, the display quality is good, then use a decade no problem, so Directly on the 5K, 8K is too far away, another decade. Just looking at the site seems to have gone 2715K. The price of Jingdong is terrible, and my full configuration does not need to be so expensive. The 2715K was equipped with a card with two DP ports, so it bought a ZOTAC 1060 6G short card and could not find the link. This site is not fast delivery, I chose DHL, the parcel issued, almost a month to arrive, if you choose EMS is express, expensive dozens of euros. Not long after the old computer was bought back, it was also a bad thing for me. In any case, it was impossible to boot the machine. So I bought a new host and bought it from Taobao. Intel 7700 GIGABYTE b250nwifi Kingston hyperx 8Gx2 Mining Fusion b48 fan Pirate ship sfx450 Joe Sibo umx1 plus Samsung pm961 Microsoft Bluetooth Keyboard Apple II touchpad in bulk No-name wireless mouse Plus Germany bought 2715K, Sotec 1060, all add up slightly lower than Jingdong's price of 2715K. This keyboard is aunt see the lowest 69, when I bought the lowest 79, but the Chinese key is 129, reluctantly bought 129, because before buying a set of Lenovo's German key wireless keyboard, it is not stand. Apple touchpad, bulk shipments, there is no quality problem. The black apple uses the 5K resolution of 2715K, a key point is to choose MacBookpro 8.1 in Clover, it seems that 8.2 is also OK, forgot to see reddit or where to see, then look for that post to be unable to find. The second key is that the DP line is not plugged in. The Windows 10 can be plugged in. The black apple is not. I don't know if it is related to the nvidia driver. I tried several interpolation methods. Two of them can be 5K. One of them can be Output sound to 2715K, the other is not, so I now 2 DP are inserted on both sides of the HDMI port, the location of the 2 lines is not exchangeable, so the location of the DP line to try. 7700 performance is actually strong enough, 7700K is not expensive for a few hundred, I mainly consider the heat, because they say UMX1 PLUS heat is not good. Gigabyte b250nwifi good board, black apple, then wifi can not be used, Bluetooth I do not know how to drive, connect the keyboard and touchpad no problem, Bluetooth headset is not enough. Cairong B48 99 blocks, more than one hundred overclocked than I bought more than three mute, and installation is also convenient, overclocking three that buckle is simply vomiting blood. Corsair sfx power is very small, but does not come with atx board, only Taobao can be installed on the chassis, UMX1 PLUS is not considered sfx power installation. Because I am a small power supply, short video card, the installation is still very smooth. NVME hard disk speed is very fast, but Black Apple is also troublesome, I was installed on the old mechanical hard drive, changed the NVME driver, and then use software to copy all the files to the NVME hard drive, rather than directly installed. Microsoft's Bluetooth keyboard feels a little harder, so typing is slightly tired and very quiet, and later I want to change my light touch Bluetooth keyboard. Speaking of the keyboard, I also bought a magic egg retro keyboard. I can only say that except for good looks, it is very difficult to use and it is all flat. Therefore, the fingers are often blocked by the health cap when I type. I bought the cherry blue axis and the space bar. Also Kaka's rebound is not rapid, but also eat gray. Apple's trackpad is also bought and tried. It is not as imaginative as it may be. It may be that my gestures are not skillfully used. The mouse now uses no-name, silent, rechargeable, slightly larger. Before I bought Microsoft's gimmick, I started to feel very good. Later, I found that my wrist was too big to hang, so I was very tired. Black Apple tossed for several days to do several drives, basically no problem, in addition to WIFI, the motherboard sound card is not driven. Usually there is no problem with it, Lightroom under the mac faster than win10 a lot faster, iMovie is also very good use of video editing software, support for 5K is better than win10, after all, to support 5k imac. Games, download World of Warcraft, Starcraft 2, Blizzard, etc., can support mac, and support 5K resolution. The price of this set may be almost the price of 5k imac, but there are i7, nvme hard drives, which are several thousand cheaper than buying similarly configured imacs. If used at home, it is worthwhile.
Absolute rotary Encoder measure actual position by generating unique digital codes or bits (instead of pulses) that represent the encoder`s actual position. Single turn absolute encoders output codes that are repeated every full revolution and do not output data to indicate how many revolutions have been made. Multi-turn absolute encoders output a unique code for each shaft position through every rotation, up to 4096 revolutions. Unlike incremental encoders, absolute encoders will retain correct position even if power fails without homing at startup.
