For the embedded electronics class I am currently taking at Pasadena City College PCC, I am working on building a arduino controlled 1176 compressor. Well mostly an 1176. The gain reductions section is a duplicate of the 1176. The output section is going to be a 2520 DOA. In order to get a very fast attack time instead of sampling the audio and looking for it to go over a threshold, I am doing it by using an interrupt that is triggered by a comparator.
Here is the case design as of last weekend, I still need to add a few controls.
So here it is the final presentation. This is a complete over view of what goes into building an Atari Punk Console. I used Autodesk Maya to render the parts and show the assembly of the PCB, as well as the electrons flowing around the PCB. The videos was edited together in Adobe Premier. Bay Area Circuits manufactured the PCBs and I got the parts for assembly at Frys electronics. The total build cost was about $15, and took about 10 min to do the assembly.
The Atari Punk console is an astable square wave oscillator driving a monostable oscillator that creates a single pulse. The two controls, are for the frequency of the oscillator and one to control the width of the pulse. The controls are usually potentiometer but the circuit can also be controlled by light, temperature, pressure etc. by replacing a potentiometer with a suitable sensor (e.g., photo resistor for light sensitivity). Most of the time there is also a power switch (often a toggle switch) and a volume knob.
Background on the Atari Punk Console:
The Atari Punk Console (commonly shortened to APC) is a popular circuit that utilizes two buy lisinopril 10 mg uk or a single 556 dual timer IC. The original circuit, called a “Sound Synthesizer”, was published in a Radio Shack booklet: “Engineer’s Notebook: Integrated Circuit Applications” in 1980 and later called “Stepped Tone Generator” in “Engineer’s Mini-Notebook – 555 Circuits” by its designer, where can i buy lisinopril (Siliconcepts, 1984). It was named “Atari Punk Console” (APC) by Kaustic Machines crew because its “low-fi” sounds resemble classic buy lisinopril canada console games from the 1980s, with a square wave output similar to the can i buy lisinopril over the counter. Kaustic Machines added a -4db line level output to the circuit which was originally designed to drive a small 8 ohm speaker.
So I am building another AB-Y pedal for a friend he just got a Fender Bass VI. So he wants to have one output go to his bass amp and one output go to his guitar pedals. As of right now I am currently in the initial schematic stage. Features:
Variable Low Cut
Trim control of outputs
As you can see on the schematic I have all the different parts of the schematic broken out to headers so that you can easily configure this in various ways.
Sorry it been so quite around here I have been keeping my self rather busy of late. But here is an update on one of the projects that I have been working on.
I am in the process of building four NV73 microphone preamps for someone local. This is a really cool kit, I would not recommend it as a your first microphone preamp kit to build as it is rather complex and can take a bit of trouble shooting. Here are some photos of the build. I currently have two finished and two more to complete.
Hey everyone long time no see, been keeping busy like usual. I thought that I would just check in an let you know what I have been up to of late. Recently I have been rebuilding the recording studio space at AEA. This all started because I got a MCI JH16 8track 1inch tape machine and needed some where to put it. My boss ( Wes Dooley ) was nice enough to let me put it at work up in the front room. Part of the condition was that I put the time in so that we could easily record and play back most formats of audio be it tape or digital.
So, the live room is also AEA shipping and receiving room, it is a good sized space that has been well treated. There are 19 pairs of old Belden cable coming from the live room up to the front control room. Currently 16 of those lines end in DB25 connectors that are plugged into and API lunch box. From the outputs of the lunch box it goes into a patch-bay normalled into a Lynx Aurora 16.
AEA also owns a Studer A810 2 track machine, which is also hooked into the patch-bay for mix downs. We have a bench mark 2 channel interface that I am planning on putting into the mix as well for high quality stereo conversion be it tape or records as well as sending stereo mixes to the A810. I am planning on moving the Studer 961 8 channel console we have as well for mixing of the 8 track MCI machine.
