MFOS designs are available from the following sites: (If you are not listed let me know and I'll list you)
Buyers! Please contact anyone you intend to buy a module from to make sure you know what you are getting first and what if any return policy they may or may not have in place. Please remember that the sale is between you and the seller.
Sellers! I will respond to legitimate complaints by removing links.

    MFOS uses DIP
    Make sure you order DIP package chips for MFOS boards. No offense SOP packages but gentlemen prefer chips with longer legs.
    DIP Spec. vs. SOP Spec.
    They actually make adapters.

    My DIY Modular

    Do MFOS circuits
    work at +/-15V?
    All of my circuits will work with +/- 15 volts and in all probability, with no changes. All of the chips I recommend are rated for the higher voltages so you should be good to go. One small consequence is that the peak voltage of things will be a bit higher. Oscillator P-to-P outputs will be higher at higher supply voltages and AR or ADSR voltage peaks will be higher also. Filters and amplifiers will have more headroom and may need a bit of re-biasing if you find that the output is not sitting at ground anymore (when the input is at ground). For any circuit to which you want to apply higher voltage examine the schematic and you'll find its not difficult to reduce the output voltage to what you want. If it absolutely, positively has to be there with a different supply voltage; breadboard it, apply the voltage you want, and tweak as necessary.

    SDIY Philosophy
    Everything on Music From Outer Space is freely available for non-commercial use. Please do not feel obligated to buy pc boards. I provide them for some of my projects so that if you are unable to make them or don't want to make them you can still do the projects. Feel free to make them from the layouts and drawings I provide or design your own if you prefer. This is not my "day job" yet, just a hobby I'm passionate about. I enjoy sharing it with the synth-diy community at large. Please feel free to use the information for non-commercial uses to the fullest extent possible. I do appreciate a link to MFOS if you blog or YouTube your work. Please keep in mind that although I use these circuits in my synth and do my best to update the information with changes or fixes, I recommend reviewing thoroughly and/or breadboarding these designs before relying on them to make sure they meet your needs. Before using any material commercially please inquire via email first.

    Thanks, Ray

    Chess PGN Player
    Click the image below to go to the Javascript Chess PGN replayer. What..? It's a program I wrote in Javascript that automatically plays back a chess game that has been recorded using PGN format. Watching the pros play is a good way to improve your own game. Works best with IE5.5 and up and FireFox.

    The Sound Lab Mini-Synth is one of the coolest little projects you can build. It is a complete mini analog synthesizer on one PC board. The Sound Lab Mini-Synth from Music From Outer Space has two VCOs, one LFO, one Mixer, one State Variable Low-Pass/Band-Pass Filter, one AR Envelope Generator with repeat, and one VCA. It runs off of two nine volt batteries for a long time due to its low current design. The Sound Lab Mini-Synth can make a myriad of sounds limited only by your vivid imagination. Creative people all over the planet are building them. I get emails from people telling me how much fun they had building it by themselves or with friends or family. Go to the Photos page to see some of the imaginative creations people have built.

    Build the MFOS Mini-Controller

    If you're into synth diy this is a "must have" you will be playing with this thing into the wee hours of the morning especially if you built a Sound Lab and don't already have a keyboard controller or you are planning on building a Sound Lab. This thing has added a new dimension to the fun I have with my Sound Lab. My son built one for his Sound Lab and he says he can't put it down.

    The fine print... This website assumes a basic level of electronics proficiency and knowledge. To build the projects found here you must be able to read and understand schematics, relate schematics to physical components, solder, do panel wiring, case building, and troubleshooting. None of these projects has step by step instructions to follow. There are; schematics, circuit descriptions, pc board layouts, suggested panel layouts, and suggested modifications. Please read over any project's information in its entirety before attempting to build it to make sure there is sufficient information for you to succeed. If you are interested in electronics or are just getting started in electronics check out this page for some ideas to help you get going: How Do I Get Started In Electronics?

    All information contained in this site is provided "as is" without warranty of any kind. Project PC board prices are subject to change without notice. The information provided by this Web site is only intended to be general summary information to the public. Please breadboard any circuit prior to writing to me for information that can only be gathered by breadboarding and testing the circuit in question. Please study carefully or breadboard circuits to be sure you will be happy with the results before you purchase project PC boards. Thanks.

    Trouble Shooting
    Dear Visitors
    Please don't email me regarding trouble shooting or circuit design advice since I regrettably don't have time to answer you. I have shared all the resources I can publishing the website.
    Here are some helpful forum links. electro-music.com and synth-diy
    Read over any project you intend to build to make sure it is presented clearly enough for you to build it and troubleshoot it yourself (or with local help). Breadboard it and experiment. Here are some good circuit troubleshooting tips.
    Good learning & building
