	The rhythm following LEDs create a party atmosphere, so I'd like to build something that can be used in a party like situation as a mixture of decoration and play of light. To make it more useful I also want it to be ornamentally in every other circumstance, like a picture on the wall with an additional light effect. My thought was that it would be more comfortable if you have no need to put it down when you don’t use the effect.

My thought was that it would be more comfortable if you have no need to put it down when you don’t use the effect.
	After experimenting with the different layers of the PCBs and finding out how to use them to make graphics, ~~I’d like~~ to create a black (solder mask) and white (silkscreen) picture with some highlights (copper mask – gold/silver). The size shall be not bigger than A4.		After experimenting with the different layers of the PCBs and finding out how to use them to make graphics, I wanted to create a black (solder mask) and white (silkscreen) picture with some highlights (copper mask – gold/silver). The size shall be not bigger than A4.

	The LEDs will be used as a frame for the picture or elements in the graphic which shine naturally (e.g. stars). Also I thought about making two different circuits at once, so a couple of LEDs glow all the time while some others blink. Because the picture is kept simple I can imagine using LEDs in different colors to make a nice contrast.

	To check if the circuit works before ordering the PCBs, I built it on a circuit board. The circuit itself works but I recognized that its perception of the auditory signal is very low.		To check if the circuit works before ordering the PCBs, I built it on a simple circuit board. The circuit itself works but I recognized that its perception of the auditory signal is very low.
	The make it more sensitive, I doubled a part in the beginning of the circuit - two resistors, the capacitor and one of the transistors (R17, R18, C2 and Q10). This change effects that the LEDs blink although the sound source is more quiet or more distant from the microphone.

	Because I had some more resistors than I needed I started experimenting with them. I used resistors with different values for the circuit of the white stars (between 0Ω and 1kΩ). As a result I changed the intensity of the single LEDs. So I have got ~~now~~ a variety of luminosity just like in the real universe - depending on how far the star/planet is away from you, the lighter or darker it shines.

	Here you can see a circuit which includes a blinking LED. The first try was a round shaped PCB. Later I updated it, chose smaller components, put them on a ~~rectangle~~ plate and added some script. The function is still the same.		Here you can see a circuit which includes a blinking LED. The first try was a round shaped PCB.
