 My name is Alexander Schremer and I want to talk to you about Tinkerforged Bricks. The mic is too, okay, Tinkerforged Bricks, no, I didn't say slide. Sorry, that was the audience. Yes. 15 more seconds for you. It is an open source hardware building block project and everything here is open source or open hardware license on a CERN open hardware license. And it was started by two friends of mine, slide please. So electronics can be exhausting. For example, microcontroller programming can be very hard. If you get timing problems or size problems, your code doesn't fit in there. Or if you want to debug a breadboard like on the lower left, then you might hit the wrong wires or connect them and end up with something which is very tedious to debug. Or if you want to solder, you need to read complex data sheets if you want to make a new circuit. So in the end, to end up with such complex projects, you need to do a lot of things and you need to learn a lot. But sometimes you only want to program, you want to make something and that's where Tinkerforged Bricks come into play. Slide please. So the idea is to have bricks like in the upper middle part of the picture. These bricks can be combined into a stack and then you can connect other things to these bricks. So let's have an example slide please. Here we have a motor driver connected to a motor and a power supply unit. And now imagine that this motor driver is connected to a computer and this computer is running some small program like two lines of code and these two lines of code and C-sharp, Python, Java, whatever or C would actually drive this motor and control it. So you actually need a connection to the system, to the computer. Slide please. You can also add a rotary port here to control the motor more complexly and this would add maybe one line of code in your piece of code. Slide please. You can also stack these bricks and then you end up with more complex systems and why would we want to do so? Slide please. We combine these bricks together on two sides and these could talk on wireless connection which is a derivative of ZigBee, it's called Chibi and so you connect the left stack to the computer and turn the poti, the program is running on your computer and then it controls the second stack which is lying somewhere in the room. So this is one central idea of this whole concept. Slide please. More information is available on www.tingoforge.org or send an email to me. You can also demo the stuff. I'm in the Hack Center at the Mon Moin table. I have a few bricks and bricklets with me. And if you want to order some, there's a rebate code here. It gives you 5% off. And I asked my friends to give out this code to get more traction maybe to get more interest, yeah. It's only valid from January 1st. Thank you for your attention. You have a minute and 37 seconds left for questions and I think you have a question right there. Question, is it open hardware? Is it open hardware? Yes, it's open hardware as in certain license so you can get the schematics and the layout files and stuff. Another question? Okay, great. One last round of applause.
