“Radiator” killed in action

Mining is a serious business so you should be very much on the spot!


You know, shit sometimes happens even if you did everything right with more than enough caution. Mining is a serious business so you should be very much on the spot!

This time my dear neighbor who is also the caretaker in that block of flats visited my flat for some reason that is not important now. He is a good, thorough man. As he entered, he noticed that I forgot to turn off that “radiator-like thing”(!) in the bathroom, so he just pulled off the plug from the wall. Literally. He made a photo of it and also sent me a quick email about the case. I’ve told you, he is a thorough man.

Unfortunately, I could read this email only a few hours later, thus there was a painful operational loss for this period.

I like him very much, honestly, but this time he just miscalibrated his attention a bit and mixed up the order of steps to do in such cases.

Bitcoin Core can be extremely slow to sync the whole blockchain, and needs outrageous amount of storage space. Most of us have fast drives but with not enough space to put the whole chain on it and a bigger drive, but with poor performance. For this case I have a solution for you.

This BIP91 / SegWit issue you might have heard about, and the uncertain effects on our precious coins of the upcoming chain split on August 1st raises a question whether we should put our money in a desktop wallet instead of leaving them having a rest at an exchange or an online wallet. Now I can see, that a desktop wallet actually does blow that haze away from the future… partially.

For instance, with Coinbase, you are going to lose your BCC(!) option. Saving your coins in your desktop wallet can be a solution for that, but of course it won’t help to avoid value losses due to volatility during the upcoming days.

Harvester 1 – Rig updates, dual mining, optimize efficiency

A report about the final setup of Harvester 1, I give you some hints to increase performance and efficiency, and a few words about optimal dual mining.

It’s been a while since I gave you an overview of our Ethereum mining rig. During these days I tried to achieve as much manna from it as I can, of course, but I also kept the initial sensible attitude to take care of the expensive components. We’d like to avoid troubles that may come with maintenance occasions and anyway, we still plan for a long run. With this approach I could finish putting the rig together to its 100% shape. This post is just a short(?) update with pictures and also I give you some useful hints below. Stay with me. Continue reading “Harvester 1 – Rig updates, dual mining, optimize efficiency”

Harvester 1 – The Birth of an Ether Mining Rig

How we built and configured our mining rig. Progress report illustrated with photos and general hints about what to take care of. Now with an extra video!


Once upon a time, the baby cried… sure, I won’t start from scratch, but I hope I can give you a general idea on how to start building your own mining rig by giving you a collection of tips and useful hints. I will also provide links to all of those interested in this crypto mining thing.
