Adding a “thermostat” to the the crypto-radiator with the Microdia TEMPer USB temperature sensor

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.

Crypto-Radiator – Saving money on heating by mining cryptocurrency (xmr/monero)

No really!…actually this is perhaps not quite as silly as it might sound.

WPforce – wordpress pen-testing tool..

Just found this wordpress penetration-testing tool – looks pretty handy, especially since it seems to have some follow-up tools to do stuff once you’ve gained access. Another one for the testing arsenal!

How to turn your Raspberry Pi and an old printer into a print server you can use from any device (including phones & tablets)

How handy would it be to have a shared network folder where you can drop a PDF to print and it just magically pops out of the printer a couple of mins later? Especially since you can print to PDF from pretty much any platform or device..including mobile phones and tablets. Pretty handy I think! Especially if you can do so with pretty much any old (or even ancient) printer rather than having to buy a funky new bluetooth/wireless one.

Here’s how to do just that…

Interesting Amazon scam (still happening so beware!)

So I was looking to buy a piece of workshop equipment recently and happened across an interesting amazon scam. Something smelt fishy right away but it took me a while to figure out what the actual “con” was…so here’s how it works…

You’re looking for an item on amazon – in my case it was a piece of machinery which was around the £400 mark and is sold under various brand names in the UK. I was after one sold under a specific brand who I’d had good experiences with in the past, especially re support, spares etc.

CCTV GUIDE PART 4 – Archiving and cleanup, and setting up the Live monitor

If you’ve followed this far and got it working you’ve probably seen this system is going to produce a LOT of JPEG files. Ours spits out around 17,000 per day.  That amount of files is gonna quickly get unmanageable.

Also linux disks tend to have a limited number of “i-nodes”, which work like name tags for files. When your disk runs out of name tags it’s “full” whether it’s actually full to data capacity or not. Storing gazillions of tiny JPEGs is a surefire way to run out of i-nodes quickly.

CCTV guide part 3 – Putting it all together –

Ok so you’ve got the scripts from part 1 and you’ve found your special url from part 2. Now it’s time to bring it all together and actually make it work!

You’ll need some sort of linux pc like a raspberry pi or similar, perhaps even a pi zero, or even just a regular linux pc. I’ve got the live monitoring part running on a Raspberry pi 2 and the logging part running on another random linux pc. It doesn’t really make much difference. The stuff we’re doing here is pretty basic and universal so you should be pretty much good to go regardless of the platform.
