Atari Punk Console
The Atari Punk Console (APC) utilizes two 555 timer ICs or a single 556 dual timer IC. The original circuit, was called a Stepped Tone Generator, and was published in a Forrest M. Mims III's Radio Shack booklet: Engineer's Notebook: Integrated Circuit Applications in 1980 and then in Mim's Engineer's Mini-Notebook - 555 Circuits. The Stepped Tone Generator became known as the Atari Punk Console because the square wave output of the version made by Kaustic Machines sounded like the classic Atari console games from the 1980s. Kaustic Machines added a -4db line level output to the circuit which was originally designed to drive a small 8 ohm speaker.
The APC is an astable square wave oscillator driving a monostable oscillator which creates a single (square) pulse. There are two controls, one for the frequency of the oscillator and another to control the width of that pulse. The controls are usually potentiometers but any variable resistor would work.

Experience Design
Experience Design: Imagine the situation in which your APC will live (5 W’s), and write it out. Who specifically is using it? Why do they use it? Where is it being used? When? What are the formal and functional requirements of this setting? How is it used (in hand or on a table)? What is the use cycle? Does it get put away? Can the end user switch out some parts (modular)?Styling: Go online and find 5 images that speak to the aesthetic (of the environment or the thing itself) that you are going for with your APC. Draw orthogonal views (top and side) of the final APC. Do 3 options. Choose your favorite.
Industrial Design: Determine the minimum size that your APC will have to be. Import the parts into Tinkercad, and build out the general shape of your internal components. Build your housing around that, and use your model of the components as a “hole” to take out from the housing. Add detailing. (Take at least 3 screenshots throughout the process)
Mechanical Engineering: Be efficient with material, and aware of the limitations of 3D printing. Reduce support material. Does it need to be printed in two parts? Consider tolerances (evaluate the tradeoff of tight tolerances that may require sanding, or loose tolerances that might jiggle).
Postprocessing: Do you want to paint the part? Do you want to sand it? Spackle it? You can make this piece look as finished as you want, or leave it in the raw PLA.

Flashing Lights
This is a 2 transistor astable multivibrator circuit. This particular version uses PNP transistors such as 2N3906, 2N4403, PN2907, or 2N2907.The 470 ohm resistors determine the LED brightness. Lower resistance means higher current, and more light. LEDs that require more current or have a higher operating voltage (such as green and yellow) may work better with 300 ohms.
The RC time constant of the resistor and the 22uF capacitor determines the on time for each side. (The two sides do not need to match - you can vary the RC time constant for one side to get a lower or a higher duty cycle).

Morning
Light Music
At the heart of this circuit is the UM66 IC, a sound generator. The IC is a CMOS LSI designed for using in door bell, telephone and toy application. When light shines on the LDR, the resistance drops and sends a signal to the T1 transistor. Power flows through the transistor to the UM66 musical integrated circuit, and a note will be amplified by transistor T2 and fed into the 8Ω speaker. The IC is preprogrammed to generate certain frequencies. When powered, the melody generator is reset and melody begins from the first note.A Little Light Music
