Video card jailbreak mining

3. Today's bitcoin mining uses amd graphics cards, which are not very different from ordinary graphics cards. You can also play 3D games on them for design. The most popular one is the hd7850 1g version, which can well balance the mining speed and price
in other words, there are a lot of "mining machine graphics cards" on Taobao, because these graphics cards use less materials under the same core and basically unchanged hash speed, such as recing video memory to improve the performance price ratio (the size of video memory has little to do with the mining speed), which can shorten the time to recover the cost
in short, the graphics card of mining machine is the core of common high-end graphics card + the workmanship of low-end graphics card, or some cheap medium and high-end public graphics card.

5. Bitcoin futures have been restricted in China. Futures are totally different from spot. Spot is a real tradable commodity. Futures are mainly not commodities, but standardized tradable contracts based on certain popular procts such as cotton, soybean, oil, and financial assets such as stocks and bonds
however, spot trading is possible in China, but bitcoin has now restricted cash withdrawal. Arbitrage is nothing more than buying low and selling high to earn the difference. Digital currency Puyin takes 1 billion Tibetan tea assets as credit endorsement. Digital currency itself has the potential of appreciation, because Tibetan tea can appreciate.

10. I'm also studying. A fully automatic machine needs the development ability of computer vision system. I don't understand this, so I want to make a manual welding machine. The camera uses the ordinary black-and-white camera, and the lens convex lens is removed to lengthen the lens to make a single lens lens. It has the ability to remove the hard disk disc and cut the group of mirrors to rece the lens distance. In this way, two CCD cameras of the camera can be welded on a PCB board at the same time. Camera fill this is simple, no need to explain. The display screen uses the display screen with reversing radar. When using it, you can directly change the XY axis image. It is difficult to display two cameras at the same time. Find argon arc welding tungsten needle as electrode, remove the arc lighter for high voltage discharge (I use black and white TV high voltage package test can be fused, but the head is too big). The propulsion motor and core adjusting motor can buy a set of stepping motor and controller, and the fixture can buy two cutting knives. Under the track modification, the V-groove still needs to be solved. At present, the conceivable solution is to use the optical fiber ceramic head to cut a small hole about 0.3mm. Of course, the accuracy is not so accurate. If you can't cut more than one at a time, just choose the most suitable two. The heat shrinkable tube heater uses a 555 delay circuit to delay, sliding resistance to adjust the time, and the heating element is made of cheap pencil lead (graphite material, 12V low voltage, almost just used. After testing, the heat shrinkable tube is not easy to stick to the surface and is easy to take off. The disadvantage is short life and easy to damage. It is suggested that the ceramic heating sheet should be coated with a layer of high-temperature cloth. The heating power does not need to be large. Generally, 2-5W is enough. After all, it is a low-end route. If the heating is too fast, it is easy to stick to the heat shrinkable tube). There are still many problems to be solved, and the key is accuracy. The design welding steps are as follows: put the optical fiber into the slot, cover the wind shield, adjust the core of XY axis, reserve the gap of about 0.2-0.4mm, press the high voltage discharge to remove st, adjust the core again, reserve the gap to the stepper motor one step or so, press the discharge first and don't let go, push the core motor step further immediately, and the discharge time should be controlled by itself because of different single mode and multi mode. In fact, optical fibers don't have to be fused. It's the same when you buy parts of optical fiber heads, heat shrinkable tubes and grinding blades to polish the optical fiber heads themselves: peel off the outer skin of the optical fiber, cover a group of fiber bundles with large heat shrinkable tubes, then cover each one with small heat shrinkable tubes, blow them with a hot-air gun until they shrink to form a protective layer, leave a section at the end without heat shrinkable tubes, cover the optical fiber head parts, and peel off the coating with Miller pliers, The optical fiber knife is cut flat, and then it is carefully put into the ceramic core and glued to assemble the shell. You can buy a ruby cutting pen without a fiber knife. The steps are slightly different. First, insert the fiber into the ceramic core and glue it well. Then, use a ruby pen to scratch along the section. Then, use your finger to cut the fiber 90 degrees across the section to break it. (the fiber is not cut directly by the cutting knife, just a small scratch on the fiber, and then apply a force to break it, If you don't understand how to cut ordinary glass, you'll know.) finally, you need to polish the tail fiber. The grinding blade should be used for special purpose. Generally, you should polish the hair according to 8 characters, and the grinding effect is also very good. When the red light pen is used to light, only when you are facing the optical fiber, you can see light from other angles. This kind of tail fiber grinding is basically no problem. Generally, this method can be used for monitoring or LAN (point-to-point, with few connectors in the middle). In fact, the light attenuation is very small. If you polish it several times, it may be smaller than the light attenuation of heat capacity. The tail fibers are mechanically polished in this way. Of course, manual grinding efficiency is very low. Hot fusion is mainly used for long-distance trunk lines. In order to save cost, small projects can also directly purchase finished leather fiber.
