How to change the power supply of Shenma mining machine

1. The fan on the excavator is of average quality, especially noisy. I used to replace it with a Japanese yamayo fan. The effect is very good, and the sound is much lower. I have been using it now.

2. You need professional chips to assemble mining machines. If you want to buy chips, I suggest you buy Avalon's third generation chips directly. But the assembly of mining machine is a very troublesome thing, the technical requirements are higher, but if you do not have professional technical strength, it is recommended that you buy mining machine directly. If you want to be an OEM, you can directly buy chips and other materials for assembly. At present, avalon3 is about to be put into the market. It is suggested to buy avalon3 directly.

3. The only difference between the mining machine split machine and the all-in-one machine is that the statistical split machine can be used separately, but the all-in-one machine can't be separated. The all-in-one machine can't be disassembled, as long as it's disassembled, it's very easy to damage

4. If you want to use the switching power supply of the computer for other purposes, you can change it as follows:
1. Open the iron box of the power supply, take out the circuit board from the box, and use a brush to remove the st
2. Find the key components. Including: power oscillation integrated block, optocoupler, 12V voltage regulator, pulse width adjusting potentiometer, etc. Find the information of power supply mole
3. First, change the 12V voltage regulator into 15V, and find the pulse width adjustment circuit according to the data of power supply integrated block. Some power supplies do not design power supply fine-tuning, but fixed resistance. Remove the fixed resistance, and connect a potentiometer whose resistance value is basically close to the welding resistance on the two solder joints. Now adjust the resistance of the potentiometer to the maximum
4. Use a multimeter to monitor the 12 V power supply port, turn on the power supply, slowly rece the resistance of the potentiometer, observe the voltage change, and adjust it to 15 v. After stabilization, observe for a little time and connect the false load toaster
5. After it is accurate, measure the resistance of the potentiometer and replace it with a fixed resistance with the same resistance.

6. The special miner can't play the game. The CPU is very poor. What's more, the miner five years ago was almost a pile of scrap iron. Why did you buy it. If the power supply rings, just change the fan. Why change the power supply.

7. Shenyang Third Ring Road, get off at Xuelian Street station, go straight south along Xuelian Street [Shengli South Street], and turn left at the intersection of Shili Jincheng.

8.

bus route: 333, the whole journey is about 13.9km

1. Walk 540 meters from Hongxing Meikailong (Hunnan store) to shouchuang international city station

2. Take 333, pass 15 stops, and reach Shenyang International Exhibition Center Station

3. Walk 430 meters to Shenyang International Exhibition Center

9. 15 days, normally 7 days
