Crypto radiator mk3 – bring in the asics

So once again we had quite a cold winter and in our extension had to rely on additional electric heating to stay warm. So despite the crypto bear market/nuclear-winter my mind turned back to the crypto radiator idea.

Even though we had to turn the ASICs off when profitability dropped below our power costs, the idea of using mining as a rebate on heating actually still holds some water.

Given that for heating our default option is literally burning electricity and getting only heat from it.,.well, an antminer can still do better than that even if below mining profitability.

Another factor is that the extension gets damp as well as cold, so things like oil radiators aren’t even that useful since they don’t move much air. But nothing moves air like an antminer!

The previously most successful heating method (before crypto rad experiments) was an LCD projector which moved a lot of air and produced good heat, whilst only using ~150w..and it displayed pretty pics or video at the same time..multi-win.

How to remotely start/stop Antminer S9, Antminer L3+ and probably others

PLEASE NOTE: This is probably not the best way of doing the thing but it is ONE way of doing it, which has been working for me. If you have a better way please let me know 🙂

EDIT: pretty sure braiins OS is a better move at this point so this is probably redundant now.

if you log into your miner via ssh and look in /etc/init.d/ you should see the script file which runs the mining dameon/program.

On the s9 it’s called bmminer.sh and on the L3+ it’s cgminer.sh. I guess it’ll be similar on other miners. If you have a different miner and want to find out what script to look for just do “top” at the ssh console and see what processes are hogging the most resources. On the S9 it’s a process called bmminer, and in the /etc/init.d/ folder there’s bmminer.sh to run the service.

Crypto-radiator 2.0

Ok so we’ve made xmr-based heating which pays for itself (and even makes a little profit), so naturally I got to thinking how we could improve this further.  Enter Crypto-radiator 2.0.

Recently price changes in the GPU market have meant that the apparent “sweet spot” for cost vs efficiency for GPUs has moved somewhat, and currently AMD Radeon RX 580s seem to be where it’s at.

Ha! Ahead of the curve much? Ethereum crypto-radiator

Just in case you were thinking my crypto radiator was a whacky idea…plus mine’s waaaaay cheaper.
