Hack a Day has great articles about hacks from all over the world. This time I want to write about a very interesting project about radio controlled lawnmower.

I wanted to build similar lawnmower with the difference that I would use Wiimote for controlling it. But interfering Wiimote directly to an AVR or other micro controller is a bit hard, so I thought of using the laptop to connect Wiimote to a mower. I already made some plans, but then I realized about the biggest problem - danger of using something like this without my direct control over it.

After all, I'm perfectly capable of hurting myself without additional help, so building this could end badly.

Anyway I'm happy that someone actually made something like this, and I have no problems about him using it as long as it's far away from me. :-D

I stumbled upon an interesting article about wireless transmission of power and thought of sharing it here.

It's really simple and cheap way to wirelessly transmit electricity on really short distance. It's made of big and small coil, a couple of capacitors and LED diode.

I'm interested in omnidirectional wheels from when I watched Prototype This!, The Discovery Channel TV series. They used these wheels in episode Six-Legged All Terrain Vehicle.

I thought a few times about building a RC car with these omni wheels, but never got around to even buy needed materials. And of course there is also a lack of tutorials/articles about it on the Internet.

Well, I then forgot about it, but a few days ago I found a post about Omni-car on Hack a Day blog. http://hackaday.com/2009/11/17/omni-car/

Really interesting project, but sadly these wheels are a bit too expensive.

Hi all,

I know my way around Linux server configuration and PHP programming, because I have a lot of experience. However, I always wanted to try programming in ASP.Net 3.5 and deploying that application to Windows Server 2008.

And so I rent Virtual Dedicated Server (apparently that's another name for Virtual Private Server) with Windows Server 2008 installed for 1 month. First of all, I had to get familiar with Windows way of work (point & click). I managed to get the idea about how to configure IIS and other tools. In Linux environment, you just connect to SSH and start typing commands. In Windows environment, you connect to a server via RDP. It's like working at a physical computer loaded with Windows.

After I successfully configured that, I started to "write" web site in ASP.Net. It is more clicking that writing source code. I had some previous experience in Classic ASP and ASP.Net 2.0, so it wasn't that hard. But more that I was programming that website, more I thought what's the point of this thing?

Yes, you can write applications, and usually you succeed. But what's with that clicking? I want to write code, not click through this and other wizard. I rented a VDS, so I guess there is no way back. And with that thought I continued with my work ... Until I realized that this is going nowhere. I rather use PHP and actually do the programming thing. Next thing is the cost. Linux VPS is not that expensive and Windows VPS can cost even a double the Linux VPS's price.

So a decision was made. Let's get back to PHP & Linux. And yes, I will cancel my Windows VPS.
