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.
Just in case you were thinking my crypto radiator was a whacky idea…plus mine’s waaaaay cheaper.
So a few little updates on the crypto-radiator (see previous post HERE) …I’ve had quite a few bits and bobs going on with cryptocurrencies in general recently and partially inspired by Monero’s recent run to over $100 I had some ideas for how to improve the efficiency of the system.
So far it’s been mining on the CPU only, which outputs about ~60Hashes/sec (H/s), clearly not gonna be profitable but the more I’ve thought about this, the more it’s highlighted the importants of the “primary reward” as a factor.
By that I mean – if you’re purely mining crypto to make profit then you have quite a tricky task, and you end up in quite a precarious position since if your system isn’t profitable (which can happen at any moment) you’re shit-outta-luck and potentially thousands of $$ in the hole.
However if your primary reward is *heat*, and you’re only using mining crypto as a way of recouping some of that cost, the situation looks a lot more favourable…since heating is something you’d have to pay for anyway, and if you can get it significantly cheaper then you’re winning, even if it fluctuates a bit.
So just a little update re the crypto-radiator – I’ve since got the TEMPer USB thermal probe working on the machine and have set it to log temperatures.
There is however a slight issue in that the usb ports are on the back of the machine and that’s also where the warmed air comes out , so the heat from that does affect the reading from the TEMPer device somewhat, which means the temperature reading can’t really be relied upon to be entirely accurate.
No really!…actually this is perhaps not quite as silly as it might sound.
