So Clay (aka c_mckamey ) and me (but majority of it is his work, i made only few minor components) build functional analog signal plotter, allowing to represent analog signal in graphical form. Plotter receives X and Y signal value via wireless logic, you can use it in many ways, for example to build oscilloscope graph (1 axis signal on timeline) or X-Y graph. For the demo we prepared few circuits, steps of "Simple" Example from first part of Rtm233's Analog signal blog (http://www.lbpcentral.com/forums/entry.php?2069-Analogue-Logic-1-Fundamentals) and inputs of Analog Stick and Sixaxis on X-Y graph, so here video: http://www.youtube.com/watch?v=HGAd326kKDU Clay plans to publish it with more demo circuits and other stuff and he gonna make wider thread about it ;]

Wow... Awsome!

So you can switch between functions using wireless logic? Very cool. This also gives me an idea, maybe someone could create a logic kit of some sort composed of premade logic "blocks" that can be put together in any combination using wireless logic!

Thanks so much for your help putting the finishing details on this and thanks also for making this video. I have been trying to explain this device to people in chat and failing at it. I think the video makes it much clearer some of the things the plotter can do. I had the idea for this thing while I was generating and manipulating a set of waves to make an analog needle gauge move based on the input signal strength. I spent about 30 minutes building the various stages of the circuit and doing the math in my head and imagining the output wave. Once It was finished, when I tried to explain what the circuit was doing to anyone, most couldn't wrap their head around it even though it was actually a fairly simple concept. I needed a way to visually show the changes I was making to the signal, then it would be much easier to see the concepts. Construction and working details will be included in the post when I publish the level but here are a few bullet points. - I had already built a signal probe early in the beta that displayed the value of a signal from -100 to +100 in numerical form. You see part of those displayed above the sample circuits. The heart of the plotter is two of those probes, one for each axis. - it's 100% wireless, both input and outputs. This let's you place tags anywhere on a chip and see the signal without stringing wires - there are 400 tags in the X and Y axis - there are 440 tag sensors in the X and Y axis - there are four numerical displays of the signal one on each edge of the graph. - the whole device, graph, and numerical displays take up about 1/2 a bubble of thermo. As Shadow said, I plan on publishing a tech demo level soon with more example circuits and perhaps give this beast away as a prize once its complete. I will even include the analog needle gauge circuits I made that were my inspiration. Thanks again Shadow for all you time with the video, Clay

@Crashdance22, huh? but then you don't have control where wireless signal goes or else you change label or color inside microchip so simple microchips with I/O where you can choose to use wires or not would be better solution. Anyway people already ditributing there own chips

would be pretty cool to use this as detection for an in-game mechanic where you draw different shapes to appear ala Trine.

Pretty cool!

Clay was probing all the logic he could find with his probe.. now he got a plotter.. no wonder all my logic icons look like faces.

Oh so this is what you were nattering on about!! Glad that you made a video about since i didnt get a word of what you explained!!
