Ardunno? Getting a fake Arduino Nano to work

An Arduino is a wonderfull thing, and i encourage everyone to support the project by buying one legit one. There are however also some cheap clones for sale on ebay like this one:

It's a NANO DCCduino, and it's pretty much an exact copy of the original Arduino Nano. I bought this online about a year ago for real cheap. I then forgot all about it untill now when my other Arduinos are occupied in other project and i just felt like testing the new servo i got in the mail today.

There were however a real issue with this knockoff. Unlike real Aduinos that show up in device manager as an "Arduino" this clone looked like this, and i was not able to upload my sketches:

Now the reason for this is that these chips dont use the FTDI chip as the regular Arduinos do. They in stead use CH340G for interfacing thru USB. And as such this requires a different driver set.
In one way this is a good thing, considering the recent FTDI anti-pirate trickery.

The CH340G driver is available for download from:

Testing Windows 10 - Virtual desktops

Windows 10 is now out as a tech preview (for free) and im currently running it as my main OS, and have done so now for a couple of weeks. I will post a few things i've noticed as i get the time, first off:

• Virtual desktops (sort off)

If you have used linux you probably know about virtual desktops, or if you have owned a ATI card with hydra vision (back in 2013 or so).
Now they have tried to adopt this into Windows but it's not the way you might know it from linux with totally separate desktops. This is more a way of minimizing/restoring apps in bulk (nothing disapears from the taskbar).

When running linux a few years ago i found this feature neat. But it didn't really improve my workflow, it rather just made my mess less visible and gradually hugging more and more ram in the background. This solution might be better in that regards, as everything stays on the taskbar so nothing is forgotten.

I've not yet been using this feature a whole lot but i like the idea.

Android not liking my certificates

At my local college you need to install and use a certificate for access to the WiFi network. This is a quite common thing, and is really no problem setting up. However when upgrading my phone's OS i ran into an issue with this annoing warning message:

Telling me that the certificate might allow strangers to snoop on my internet activity, while in fact the oposite should be true. Anyways the message is highly annoying, and pops up at every reboot.

Now the solution for this is to simply move this user installed certificate from the "user installed" - folder over to the "system installed" -folder. Since Android doesn't throw this warning for the system certs. This solution requires root.

Using a file manager with root access (I use Root Explorer) go to:
/data/misc/keychain/cacerts-added/

This is where you will find your user certs. Copy it over to this folder:

/system/etc/security/cacerts/

And you will no longer be bothered with this annoyance in the future :)
