Instead of getting a nice thin film I get bubbles of water floating threateningly over my hardware! I lost my first and surprisingly hard to replace power supply to a rouge water bubble. I found a large outdoor electrical box to store the raspberry pi, USB hub powers the pi and smaller bitcoin miners.
The sink isn't totally full of oil that stuff is kinda expensive , I've placed the radiator flat on the bottom and placed the heat sink on the mining hardware flat on top with enough oil to just cover the hardware. I've decided to keep the power supply out of the oil, mostly because it's still not super-clean and I don't trust the setup for to keep the elements out just yet.
The pond began at 0'C had frozen ice at the beginning of the experiment. I'd love to hear some suggestions on how to study the thermal effect I'm having on the pond. So far I know it was able to quickly raise the temperature 4'C. Perhaps I need to move the thermal probe from the to the environment so I normalize the weather out of the pond temperature.
I'm still experimenting with aquaponics, and I'd like to get something to grow before I get to far ahead of myself. The point of this exercise is to find a way to keep the fish tank warm during the winters in Colorado so our fish might survive from year to year. I'll have to get more bitcoin mines :. I'd like to partially bury the tank but that will have to wait until summer and more commitment to the project.
This is my first instructable, I'm sure I've left out critical details, or pictures that you'd like to see. Please feel free to recommend improvements, I've got thick skin :. You really shouldnt mix Oil and water, Reply 5 years ago. I agree, I'm using a transmission radiator from a truck as my heat transfer interface. Ultra copper from your auto parts store. It seals valve cover gaskets Use that around the pipes before fitting the hose. Good as gold. I think I'll be using that for my heater next year too I'm thinking something perhaps much longer vertically then necessary, but enough to give you a great deal of thermal transfer though the housing itself in addition to any radiated water.
Reply 6 years ago. Bad news, wife was shoveling snow off the deck and accidentally tossed a scoop of snow down on the setup. The force shattered the plexiglass and took the system offline. Not sure if the hardware survived letting it dry out but I'm redesigning the setup. I also discovered that the radiator probably the hose clamps was not perfectly sealed and oil was leaking into the "pond" when the pump was turned off, a lot of oil got siphoned into the pond.
Looks like I'll spend some quality time boiling out the water to recover the oil I but the cheap now so it's hobby money. By Malkaris Follow. More by the author:. First it's worth exploring some of the cons of running bitcoin mining or heavy computing in general 1. Noise 2. Heat 3. Did I say noise? The noise isn't from the computers but the fans keeping air over the parts. Thermally conductive, better than air, not as good as water 2.
Electrically insulating, at least as good as air and and better than water! Fountain pump 60GPH 6. Optionals: USB thermometers: temperature monitoring isn't strictly required, but it's interesting to know whats going on. It makes the oil look funky too : Eventually I upgraded to 60GH GigaHash bitcoin miner and the power was too much, I saturated my passive system and it nearly melted the tank! For my "pond" I'm using a gal stock tank. I added a pair of USB thermometers to monitor the temperature of the oil and the pond.
Some things I'm observing. I'll have to get more bitcoin mines : 2. There are two primary reasons why a person, or company, would want to mine cryptocurrency like bitcoin. In order to validate and add new transactions to the blockchain, miners must compete with each other using specialized computing equipment. The target hash is a digit hexadecimal code comprising numbers and letters A-F all miners are trying to get below in order to discover the next block.
Remember, just changing a single bit of the input produces a totally different hash. This is why miners have to invest in energy-intensive computers, particularly application-specific integrated circuit ASIC miners, that can generate trillions of hashes per second. An easy way to think of bitcoin mining is to imagine each new block is a treasure chest with a combination lock on it. To get the free bitcoin block reward inside and win the right to add new transaction data into it and collect the associated fees you have to keep turning one of the number wheels on the lock the nonce until you crack the combination the target hash.
To see just how difficult it is to generate a hash with more zeros at the front than the above target hash, try creating a winning hash yourself with this free online hash generator. Simply type anything you want in the text box provided and see if it produces a hash with more than 17 zeros at the front! A hash is a cryptographic mathematical function that converts any message or data input into a fixed-length code.
Think of it as an encryption technique where messages are mathematically transposed into a sequence of numbers and letters of a fixed length. The outputs have set lengths to make it impossible to guess the size of the input. The same input will also always generate the same sequence of letters and numbers.
In the case of Bitcoin, the blockchain uses Secure Hash Algorithm or SHA to generate a bit or 64 characters long output, regardless of the size of the input. For every new block added to the blockchain, the protocol — a set of rules programmed into Bitcoin — releases a fixed amount of newly minted coins to the successful miner.
This block reward system doubles as the distribution mechanism for Bitcoin. This figure was reduced to 25 BTC in The most recent halving occurred in , and saw block rewards fall from Note that bitcoin has a 21 million maximum supply cap, and we already have Block rewards will no longer be distributed once 21 million BTC has been released to the market.
Once this happens, miners will only be able to earn rewards in the form of bitcoin transaction fees. Even with this combination of two revenue sources, not every miner generates profits. Also, as mining difficulty increases, large mining operations are forced to expand or upgrade their equipment to maintain a competitive edge.
Each miner agrees to share rewards according to the contributions of each miner. There are, however, some rare instances where solo miners have successfully mined blocks on their own from home. An important thing to know about Bitcoin is that when Satoshi Nakamoto created the protocol, they programmed in a target block discovery time of 10 minutes. This means it should take approximately 10 minutes for a miner to successfully create the winning code to discover the next block.
The Bitcoin protocol has the ability to automatically increase or decrease the complexity of the mining process depending on how quickly or slowly blocks are being found. Every two weeks, the Bitcoin protocol automatically adjusts the target hash to make it harder or easier for miners to find blocks. If they are taking too long more than 10 minutes the difficulty will adjust downward; less than 10 minutes, it will adjust upward.
More specifically, the protocol will increase or decrease the number of zeros at the front. This might not sound like much, but just adding a single zero to the target hash makes the code significantly harder to beat, and vice versa. This subsequently led to remaining bitcoin miners reporting significant rises in mining revenue. Through this system, the Bitcoin protocol is able to keep block discovery times as close to 10 minutes as it can.
You can track the mining difficulty of Bitcoin here. While actively participating in the Bitcoin network can be a highly rewarding venture, the electricity and hardware requirements often limit its profitability — particularly for miners with limited resources. One of the biggest drawbacks of Bitcoin is the vast amount of energy it uses to mine new coins, validate transactions and secure its network.
This means bitcoin miners collectively attempt to crack the target hash of the next new block quintillion times per second. The main reason for this extreme consumption is because each time bitcoin rises in price, it encourages new miners to join in the battle to win new coins and forces existing outfits to purchase more rigs or upgrade their equipment to remain competitive.
When this happens, the amount of computational power used to mine bitcoin increases hash rate increases which, in turn, causes the bitcoin protocol to ramp up the difficulty so that blocks continue to be discovered at a steady rate every 10 minutes.
A natural byproduct of this increased competition is higher energy consumption — the more machines whirring away to mine bitcoin, the higher the collective energy consumption.
