Looks like typical geiger tube used, and typical circuit for it. What's "new" or "original" there? And definitely not low cost stuff, but poorly built (all that hanging wires).
Also his microcontroller memory most probably will fail on serious radiation, and if not stop working, then may give invalid data.
I understand detecting alpha particles in the tin can over FET transistor can be MUCH cheaper than those (but more for alpha, again), and similar original ideas.

Exactly. With all this ecstasy from revolution, people should look a bit which statements Praviy Sector and Svoboda made before.
Before revolution they said several times, that Russia, Poland and several other countries own their territory, plus their hymn include "russians on knifes" and "ukraine for ukrainians". Now guess, what will happen when they have nukes.
I was shocked, when i so how their "activists" attacked veterans of WWII, 80+ year old people, in 2011, Lviv. Check youtube for that.

In case Dell used speakers that are not rated even for their motherboard amplifier - it is trivial to detect audio clipping that VLC cause, just a plain resistor and current sensing circuit, or a comparator on output circuit and it will be easy to shut it, before speaker got damaged.
In car industry it will be a recall and faulty items will be replaced by modified ones, with "bugfix".
But it is very known - freaks like HP and Dell prefer to charge customers for each sneeze, and as soon as you paid and took your product - you are on your own. No bugfixes, no support, no improvements.

According to researchers statement TP-Link seems doesn't care to give an answer about issue.
Good news: Users who reflashed their TP-Link with Open/DD-WRT firmware can sleep well."

I guess it can be only gulf countries and i'm in one of them right now (most restricted country, hehe). Please take a note, that they are tracking VPN activity, and some countries who block VoIP, can block your VPN too, if they suspect you use it for VoIP. I recommend PCI compliant VPN, to PCI certified hosting, if you want to do banking. E.g. if you want to go serious way, find collocation (PCI compliant!), let's say 1/4 of rack, put there VPN router (also, again,compliant), and your side too. Note, that some services like Netflix, PS3 videos wont work for IP's from hosting, because some people from other countries use this way to get US address, and services are blocking all hosting IP ranges, so you have to test it first.
Sure you can go cheaper way, it won't be compliant, but still very secure. Let me know if you need more information.

Now using my electronics how i want is "certainly not a guaranteed right". WTF. Thats why we had DIY talents before, who was building companies in garage, and now we have army of "angry bird" players, because it is not easy to create something this days.
You can't reuse electronic parts. SMD. You need expensive tools to do that. Well, ok, let's say it is ok.
You can't reuse blocks and highly integrated IC's, because there is NDA for documentation and high fees to get this documentation.
And now, finally, soon you can't write your own low-level software, because your PC manufacturer will decide, what you can run, and what you can't.
I hope my car one day will not tell me, which road i can take, and which one i'm not allowed to go, because my car don't have license for offroad.

I was involved in development of some hardware players (Sigma chipset). And media companies plays there major role. And most important for them IP. This means DRM. Also this means NDA. Realtek, Sigma, all the same in that.
Amazing hardware power, but very locked down before product release by patent restrictions and DRM.
I believe the best you can do and archieve your goals - Atom with some kind of GPU acceleration, but again proprietary drivers, to get acceleration.
FPGA i believe will need too much efforts for one person, to support all media formats
