Kako ogreti svoje Home z Bitcoin Rudarstvo

This guide walks you through integrating a bitcoin mining rig into your home’s HVAC system, recapturing heat from the process and saving money.

It is easy to forget, but innovation in Bitcoin is not purely digital.

Most see our “magic internet money” as something purely esoteric, but there is one aspect of our ecosystem that squarely straddles the line between the digital and the physical: bitcoin mining. To the layperson, bitcoin mining is an alien phenomenon — you buy a strange looking metal box, put it in a warehouse somewhere and consume significant amounts of electricity. However, to tinkerers, hobbyists, entrepreneurs and adjacent industry professionals (in the farming, real estate and oil and gas sectors, for instance), bitcoin mining is an opportunity to add efficiency and margin to highly-competitive spaces while recapturing costs and waste.

In that spirit, what follows is a simple framework for using bitcoin mining to add warmth to a residential home, keeping in mind that the concerns of a warehouse or a hash hut are different from those of a home. Where you would try to squeeze every terahash from a machine in a hosting facility, our concerns in a house revolve around safety, sound, convenience and cost recapture in residential heating.

Enostavno ogrodje

We are going to integrate bitcoin miner heat output (a Bitmain S9, in this case) into our HVAC air return. The general thought is that it will accomplish two things: One, it will constantly “drip” heat into our HVAC system, which should, in theory, constantly push a low volume of warm air into the house without spinning up the HVAC system, and two, when the heating system and HVAC fans spin up, our miner should supplement the heat production of our heating system, requiring less energy use (gas in our case).

Seveda, a home miner can use a new-generation machine for the same purposes I’m detailing above, but for the sake of accessibility and startup cost, I adore the older generation S9 as a tool for learning and tinkering. They are physically robust, easy to acquire and can be run on your standard 110-volt electric system while tuned with Braiins firmware for greater control.

Moj poseben načrt je, da uporabim prostor nad mojim sušilnikom za montažo minerja in zahtevanega cevovoda. V interesu ublažitve hrupa in zadostnega hlajenja skozi kanale bom iz S9 odstranil osnovne ventilatorje in uporabil vgrajeni ventilator (an AC Infinity CLOUDLINE S4, ki v času pisanja stane približno 100 USD), da potegnem zrak iz zunanje odprtine, ga potisnem skozi rudar in nato vržem v moj povratni kanal HVAC.

Kaj bomo potrebovali

Spremenili boste, kar delim spodaj, da bo ustrezalo vašim lastnim prostorom in proračunskim omejitvam, vendar bi morali imeti vsaj dostop do ročnega orodja, rokavic, vrtalnika in nekaterih različnih rezalnih orodij za brušenje/oblikovanje tanke kovine.

Prav tako boste morali pridobiti ustrezne kanale (izolirane, s folijo ali gladke po vaših željah) za vaše namene, začetno objemko, ki jo boste namestili na povratno stran, pravilne reduktorje ali objemke za morebitne spremembe velikosti, tesnilo in trak za končno nepredušno tesnilo in montažna oprema za vaš ventilator in rudar.

Namestitev vodov

Najtežji del gradnje je bilo izrezovanje luknje v povratnem vodu HVAC za namestitev začetnega ovratnika (kjer se toplota dejansko odvaja v sistem iz rudarja).

I began by tracing the starting collar shape on the return, then drilling a hole into the middle of the traced circle and, while wearing gloves, cutting in an expanding circle until I hit the traced line (the outer edge). The work was cramped, uncomfortable and produced a gnarly little piece of metal that attempted to cut me at every pass. You must wear gloves — I repeat — you must wear gloves. It is also advised to use proper tin snips and not the dinky, home DIY snips that I used.

Z okroglo luknjo, ki je bila vrezana v moj povratni vod HVAC, sem lahko grobo namestil začetni ovratnik. Dodatno brušenje, rezanje in vlečenje je bilo potrebno, da se je ovratnik poravnal s povratkom. Ko je bil nastavljen, sem lahko segel skozi ovratnik in se upognil čez jezičke znotraj ovratnika, da bi ga držal na mestu. Temu je sledil sloj tesnilne mase za HVAC in trak, da je kos varno pritrjen.

Ko je težji del gradnje končan, sem začel montirati adapterje in kanale. Za obešanje cevi na izpostavljene čepe sem uporabil preprosto tehniko vezanja. To omogoča enostavno montažo in prilagajanje za kakršne koli natančne nastavitve v prihodnosti. Prepričajte se, da pritrdite točke za pritrditev kanala s sponkami HVAC in jih pokrijete s trakom, da preprečite uhajanje zraka ali piskajoče zvoke, ko sistem deluje.

Montaža vašega ASIC

V smeri dovoda zraka nameravamo namestiti ASIC nad pralno/sušilno enoto z uporabo kosov iz splošnega gumiranega kompleta za stensko montažo, ki ga lahko najdete v kateri koli trgovini s strojno opremo. Presenetljivo je, da se generični nosilci prilegajo rudarju in napajalni enoti (PSU) na način, ki omogoča pritrditev na steno in strop.

Končni priključki in nastavek za ventilator

Morda se sprašujete, kako bomo naše kanale namestili na naš ASIC. Za to se obrnemo na 3D-tiskalnik, da izdelamo dva ti (prosto dostopen). Če nimate dostopa do 3D-tiskalnika, lahko s preprostim spletnim iskanjem najdete različne nosilce za nakup.

Zadnji del našega sistema je vgrajen inline ventilator. Uporabljam isto tehniko povezovanja z razpoložljivimi nosilci na ventilatorju kot na kanalih, saj menim, da bo to zmanjšalo verjetnost kakršnih koli neželenih vibracij v sistemu.

Če uporabljate isto tehniko ožičenja, ki sem jo prej poudaril v Vodnik po rudarjenju za stanovanjske prebivalce Bitcoin,« boste želeli ventilator namestiti blizu naprave, da boste lahko uporabili razpoložljivi vtič in imeli vse čisto na eni vtičnici.

Ko sta ASIC in ventilator nameščena ter ožičena, lahko začnemo s testiranjem sistema in zgoščevanjem. Spreminjanje nastavitev za delovanje brez ventilatorjev je v Braiinsu izjemno enostavno. Z vgrajenim ventilatorjem na 90 % moči in ASIC-jem, znižanim na 900 vatov, sem pustil, da Braiinsova samodejna nastavitev deluje čarobno. Najprej sem opazil, da je uglaševanje trajalo neverjetno dolgo, ko je delovalo brez ventilatorjev. Sumim, da je vlečenje zraka od zunaj 24 ur na dan 7 dni v tednu zmešalo sistem za uglaševanje. Medtem ko je bila v Koloradu zima in je zrak stalno hladen, smo zaradi našega suhega podnebja čez dan deležni velikih nihanj temperature okolja. To samodejnega uglaševanja ni najbolj zadovoljilo in težko je ustvarilo stabilen profil.

Poleg tega je bil eden od mojih ciljev za ta sistem čim bolj tih. Opazil sem, da je vgrajeni ventilator zelo, zelo tih. Tako zelo, da sem začel slišati drug zvok, ventilator na PSU. Da, ventilator na napajalniku je bil glasnejši od vgrajenega ventilatorja, ki potiska zrak skozi ASIC.

To remedy these problems, I made two modifications to the system. The first was to detach our inlet from the outside ambient air, and to instead mount an automotive cold air intake directly to the inlet of the inline fan. By drawing air from my laundry room directly, I am able to keep a more consistent input temperature, which assisted greatly in tuning via Braiins. Also, by drawing air from the inside, I don’t create a pressure differential in my house by pulling air from outdoors into the home via the inline fan. I don’t believe this will create issues at small scale, but am happy to avoid any problems that may arise from this going forward.

Poleg tega sem kupil 60-milimetrski ventilator Noctua, ki je zamenjal standardni 60-milimetrski ventilator napajalnika. To je zahtevalo manjši električni poseg, saj ima standardni ventilator dva zatiča, Noctua pa tri. Preprosto sem priključil glavne črne in rdeče napajalne linije od Noctua na PSU, tretjo žico pa pustil nepritrjeno. Ventilator deluje brezhibno pri polni hitrosti in zvok je zmanjšan.

V povzetku

After our initial construction and final tuning, the system has stabilized at around 800 watts consumption and is consistently producing both ambient heat in the home and about 10.25 terahashes per second. I believe the modified PSU fan is our limiting factor in power, as the Noctua doesn’t push as much air as the stock PSU fan. This isn’t a great concern to me as my goal isn’t to squeak as many hashes out of my machine as possible. Rather, my goal is to integrate bitcoin mining into a residential setting while maintaining quality of life (sound and safety of living space) and to repurpose the waste heat usefully.

I believe I’ve accomplished both and hope you will feel confident in building out your own systems of ASIC home integration. These are the early days of home mining. Residential products like the Upstream Data Black Box are in their infancy and open the door to entirely new and creative categories. Bitcoin mining isn’t just for the big boys, and you’re more than welcome to join the conversation as we build and learn together.

Srečna gradnja.
