Wave Generator/ O-Scope - Legofreak - 08-25-2014
Quite a few of you guys saw me working on this.
Over the weekend I was derping around with hex serial and I found I could produce some neat waves. After some tinkering, I made a display that draws all points between outputs when the output changes. this allows for drawing of waves on a screen.
At first I was driving it with a long line of memory but I didn't like how big it was.
Then I came up with the idea of generating the wave with hardware. I created a double inversion memory cell that I can control how much and how long it adds or subtracts. This creates a triangle or sawtooth wave. Depending on the settings you have, you can adjust the Frequency/Wavelength and Amplitude.

After I made one I copied it and connected them to add the waves together. This results in some really neat complex waveforms.

I think with some more tinkering, I can get the UI much more user friendly and possibly some better functionality.
One thing I haven't figured out yet is how to make a vertical screen that can react to 2 tick pulses and display properly. Lamps are too slow, and I'm worried pistons would be too laggy. Right now, a flat surface of repeaters seems to be the best option for the display.
I was too lazy to take screenshots... I'll try to get around to it later.
Edit: SCREENSHAT

This is quite the wizardry. I'm surprised nobody has thought of doing this before. It looks insanely cool in game
RE: Wave Generator/ O-Scope - AFtExploision - 08-25-2014
Newo is your reaction to everything about hex "surprised no one had thought of it". Now make a receiver
RE: Wave Generator/ O-Scope - Legofreak - 08-25-2014
What would a receiver do anyway? It's just 2 tick serial hex. If it's just to save the stream then it should be fairly easy. Maybe detect frequencies? I don't know what else you can do with a wave in minecraft besides look at it.
RE: Wave Generator/ O-Scope - AFtExploision - 08-25-2014
I meant detect frequencies, then we'd have a closer representation to irl analog
RE: Wave Generator/ O-Scope - greatgamer34 - 08-26-2014
very neat, can you set a warp to it?
RE: Wave Generator/ O-Scope - Legofreak - 08-26-2014
I'll set a warp when I get a good enough version that other people could use. But if you /warp rekdir , it's near the end of the platform.
Its neat when you can tell the waves are cancelling, and then doubling. this is 2 of the same wave added together a little out of phase.

RE: Wave Generator/ O-Scope - Legofreak - 08-26-2014
New O-Scope has 31 lines for more space when adding waves.

hooray lag!
RE: Wave Generator/ O-Scope - greatgamer34 - 08-26-2014
i love it. Keep up the great work!
RE: Wave Generator/ O-Scope - Legofreak - 08-27-2014
Last night I made something slightly resembling a sine wave. The function for it, at least on one setting, is:
+1,+2,+3,+3,+2,+1,+0,+0,-1,-2,-3,-3,-2,-1,-0,-0
It's a pretty simple pattern but kinda frustrating to time it properly considering each sum/difference has to happen every 2 ticks
