DIY Raspberry Pi Bitcoin Mining Machine

Don’t think you are awesome just because you have a big Bitcoin mining machine. Although the speed of the Raspberry Pi Bitcoin mining machine is not very high, it is a rare successful work of Raspberry Pi DIY!
The maximum speed of the Raspberry Pi Bitcoin mining machine can reach 380Mh/s, which is close to the speed of the mid-range graphics card HD7850. This graphics card usually costs 1,300 to 1,400 yuan. You don't need to judge which one is more affordable.
No explanation, just pictures!
[This is a group photo] The small box below contains the Raspberry Pi, and the box is for the TP-Link switch.


【Full face】


[Separate into two parts]


[Host Raspberry Pi] The hole on the front is a 3.5 headphone jack, which is actually useless for the mining machine.


[On the side and back] there are SD card slot, power cord hole, HDMI, USB (soldered by myself, see below for details), and two holes were drilled with an electric drill.


[Base] The bottom is a 4-inch metal base, which is actually 4 earphone shells. The base in the upper left corner is cast with metal and directly connected to the motherboard to prevent static electricity (see below for details)


[Inside] The upper cover can be opened with a suction cup


【Grounding and anti-static】This is for grounding. I got shocked once before. Newly added.


【USB】The original USB is too high, and this case can't cover the top, so I took it apart and put it together with the HDMI. I soldered it myself. It was originally very beautiful, but the hot glue q1an9 didn't do it well.



[Network card] The original network cable interface was too high, so I removed it and soldered a USB network card on the back. The black and white one is the antenna I modified myself, and a hole is reserved. If the signal is not good, you can add an antenna on that hole and connect it to this antenna.


【Mining machine part】


[Heat dissipation] The miner is very small, so heat dissipation is a big part of it. Don’t underestimate this miner. After overclocking for a night, you can fry an egg the next morning. I have measured it with an infrared thermometer before. The room temperature is 20 degrees, and the miner is close to 80 degrees. After adding this heat dissipation, the lowest temperature is equal to the room temperature, and the highest temperature is only more than 30 degrees.


[Close-up of the mining machine] All joints are made of very good thermal grease. It is not top-notch, but it is the best one I have ever used.


[Additional heat dissipation] You can choose to have or not have this fan. The temperature test just now was done without a fan. If a fan is needed, I will solder it in advance, and the fan will rotate automatically after power is turned on.


After witnessing this, is there anyone who dares to say that he was not blinded by it? ? ? ? ?
