Trouble-shooting |

Dear Visitors
I have always said that when I begin to spend more time managing MFOS that I would
answer more emails so... I am spending more time managing MFOS. Please make sure your question is not
already answered on the project of interest's page before emailing. If it's not and it is legitimate
(not like "my hand gets really hot when I solder... what am I doing wrong?").
I'll be happy to respond time permitting. I'll probably set aside a day for answering emails.
Read over any project you intend to build to make sure it is presented clearly enough for you to build it
and trouble-shoot it yourself (or with local help). Breadboard it and experiment.
Here are some good circuit trouble-shooting tips.
Good learning & building

MFOS Module Makers
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.

My Open Source
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

The Sound Lab Mini-Synth is a great project. It is a complete mini analog synth on
one PC board. It 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.

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.

Your home-built synth music on the RADIO! Read on...
Bill Fox hosts two shows that feature electronic music. He is interested in hearing the
music people make on their home built synths. The best of these compositions may get airplay.
Bill will accept CDs sent to the address below. Bill will NOT send a review to
everyone who submits a composition. If you get one great, if not, leave the guy alone.
Do not get dissapointed if you don't receive feedback or a review.
Never say die and never give up the ship.

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 trouble-shooting. 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?

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

When using the custom wire-wound tempcos (PT146 or PT094) from MFOS I usually
put a 100pF cap across it in the voltage summer. It seems to calm down any inductance
added by the tempco's winding. As usual if you don't have any problems leave it alone. RJW

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.
