Rpi news
I got 3 more Pi3's. One replaced the faulty #9. I added fans to the tops of a couple of the official Pi cases. Unfortunately I didn't get the hole centered on one of them so that is one case messed up. A second Pi3 (with fan) has been installed and is now crunching away. I will add the other new one into the mix which will bring the bramble up to 10 Pi3's crunching.

The Pi2's have been retired. The bramble is close to 2 million credits of Einstein crunching.


Other news
Debian Stretch is being released as I write this. I will wait a week or two before looking at upgrading crunchers. Jessie is still supported for another year. It may be better to clean install Stretch rather than upgrading them from Jessie.

I tried the GPS receiver on a couple of machines, one Intel and a Raspberry Pi, it would happily talk to the computer but it seems it couldn't get a fix on the satellites. I had it stuck to the inside of a skylight window. Its not weatherproof so I can't just hang it outside. I will try it outside for a short while to see if I can get it to work.

Rpi news
It seems there is a Trojan out that specifically targets the Raspberry Pi. Apparently a lot of people don't change the default password. Here is a link to the article: http://www.guru3d.com/news-story/new-linux-trojans-installs-crypto-currency-mining-software-on-raspberry-pi.html

The copper heatsinks from Enzotech arrived yesterday. I have ordered 3 more Pi3's and a couple of cases.


Electricity price increase
My current electricity retailer has announced a 16% price increase for electricity and 9% for gas from the 1st of July. There are a couple of other retailers I could switch to. I will compare them but I expect they will all increase around the same time.

The electricity price increase would mean the Ryzen upgrade (from a 1700 to 1700X) would not be cost effective. It uses another 30 watts for around a 10-12% increase in output. I might have made the right decision about which Ryzen chip to get after all :-)

I have seen a natural gas powered generator around the size of a washing machine for business use but they have a high purchase price. A diesel or petrol powered generator is going to be cheap to buy but cost a lot to run. Its time to look into a solar and battery solution.


Other farm news
My current planning has me looking at another pair of Ryzen 1700's. I have spare cases, hard disk drives and graphics cards for them to keep the cost down. This would free up the i3's for something else although I don't currently have anything in mind for them.

Other news
Last weekend the farm was off, except the Raspberry Pis, due to having to attend an out of town wedding. The Ryzens and the storage server were delivered the day prior to the wedding. Unfortunately I didn't have time to configure them before leaving.

The first Ryzen was setup last week and spent the week running different projects before switching to Seti work. The second machine was setup yesterday and is also doing a range of projects. Performance is a bit slower than the Intel i7-5820K's that they replaced. I am considering replacing the Ryzen 1700 with 1700X CPUs (3.4GHz base clock) but have to weigh up the extra power consumption (another 30 watts). I will also need to replace the heatsink but can reuse the AM4 mounting kit. Each Ryzen also has a GTX1060 installed.

The firmware still hasn't caught up with the Ryzens and Linux throws a number of errors when starting up even though I have a 4.9 kernel installed and the latest firmware from ASUS. I expect they will need a few updates before most of the bugs are fixed.

I've got another batch of 14mm copper heatsinks on the way from Enzotech, so I can look at replacing the two Raspberry Pis mentioned in my last blog post. I still need to look at a better case for multiple Pis.
