![]() ![]() ![]() Everything you need will be on hand (including handouts AND snacks), so just bring yourself and a notebook. No experience wiring or soldering necessary. Learn how to do this the right way, so your custom pedal lasts forever (and if anything goes wrong, you can fix it). A mix of discussion and practice, we’ll speak briefly about how these things actually work, but to be clear, this is a BUILDING course where students learn the fundamentals of circuit construction, proper soldering skills, reading layouts. This is old-school, point-to-point wiring: nothing digital or preprinted. Together, we’ll assemble a bare-bones model then the circuit can be modified and personalized endlessly, so everyone’s finished console will be unique.Įverybody starts with a bag of discrete components and vintage-style eyelet/fiberboard, and everybody leaves with their own unique noise unit. Over the course of this two-day weekend workshop we will construct an Atari punk console, a wild and barely predictable noise-maker/self-oscillating synthesizer capable of everything from bird-like chirps to fuzzy pads to rumbling bass tones. ![]() While you could use a microcontroller to obtain a similar effect, this circuit is an approachable, useful introduction to both capacitors and the incredibly popular 555 and 556 integrated circuit.Weekend of February 18-19, 12:00PM-3:00PM Hearing the funky retro sounds of arcades of old is a great payoff to a correctly built circuit. You can even hook an oscilloscope to the output to see how the waveform varies as you twist the knobs.įig 3: An oscilloscope can help visualize what is going on with your new instrument.īuilding a Stepped Tone Generator is a fun experiment. Add on to the circuit by chaining more components to its output, or by interfacing a microcontroller to change things further. This modified version shows how versatile Mims’ circuit is, and you can experiment further with different capacitor and potentiometer values. Capacitor connected to speaker is 10μF, others are. Without clipping the wire, you’ll have a barely-visible 556 timer surrounded by a forest-pardon the pun-of unintelligible hookup wires.įig 2: Simplified Stepped Tone Generator Layout. We recommend single-strand wire that you connect and clip to the correct length. With those parts in hand, all that’s left to do is connect the circuit as diagrammed in the image below. Hookup Wires (single strand 22 gauge recommended) (2) CR2032 coin cell batteries and (1) holderĩ. The parts list for this build is fairly simple, with components that are easy to find in a well-stocked shop:ġ. (1) 556 timer chip (or two 555 timer ICs)ħ. We subbed 200k potentiometers for the 1M pots originally used. We’ve outlined a simplified version of Mims’ circuit, omitting the volume potentiometer and using a pair of CR2032 coin cell batteries to save space. Controls consist of two potentiometer knobs: one varies the sound frequency and the other controls the width of each generated square wave.īuild your own Stepped Tone Generator using the parts list and instructions below The name Atari Punk Console (APC) references the results of this build, which sound like a 1980s arcade game with their distinct bloops, bleeps, and hums. Mims’ design outputs sound signals directly to a speaker, and engineers have tweaked this simple design in countless ways, including the line-level “Atari Punk Console,” commonly used with powered speakers. This instrument, called a “Stepped Tone Generator,” was designed by Forrest M. The game features four differet playable characters, that take on contracts across various plates for money and fame. All of that in a crazy but cool-looking sci-fi setting. Fig 1: Simplified Stepped Tone Generator, also known as an Atari Punk Console Space Punks is a top-down shooter RPG with online co-op, that combines elements from Diablo with those of traditional loot shooters like Borderlands.
