Sorry to be late in updating this thread, but I've got quite a lot to sort out, and I don't really have any Bitcoin news.
I put a rip saw blade on my angle grinder ( basttery powered), and it makes a brilliant chop saw. I need to be careful, as it quite a lethal device.
The node in my laptop is running well after I installed a 2Tb SSD. It's brand new, so the wallet is empty. I've got some coins on the drive in an old laptop that has died, so I need to extract the hard drive, and add those coins into the new wallet. I have tried this, so I need to do a bit of research. Maybe that is worth a new thread.
I agree that I need some solar panels. The Maxus I bought was previously owned by a canoeist, so the roof bars are at the extremities of the roof. I'll probably need to add a third bar in the middle. I bought to van for about £2,000 less than the market price, as it has a bunch of minor problems. The central locking doesn't work, and the driver's window doesn't open for example.
I'm running the node intermittently by using supermarket cafe WiFi. That seems to be really effective, but I'll need to change things if I start spending Bitcoin. I'm using Bodhi Linux, and that seems to be secure and trouble free.
The mining project is probably a good few months into the future. I'm not sure where I would create a comms centre. At the moment I've got a large spare wheel mounted inside the van, and I need to find a carrier to mount it under the van. I don't understand why this wasn't a standard fitment, but the Maxus was created to be a reliable but cheap working van.
I suspect that the only way to make money from a small mining rig is to post YouTube videos about it.
