Basically, the Ekdahl Moisturizer is a spring reverb where the springs are exposed so they can be played/hit/fiddled with. As well as being capable of creating sound in itself, you can of course also play sound through the springs like a regular spring reverb - this makes for happy-fun-time finger-modulation of the reverb on whatever audio that's going through it. |

Arthur Harrison is the president and CEO of Harrison Instruments, Inc., a Maryland company that designs and manufactures the early electronic musical instrument called the "theremin," named for its inventor, Leon Theremin. Mr. Harrison sells theremins to both domestic and foreign markets, and is considered an international authority on the technical aspects of the instrument. His theremin circuit designs have been implemented by electronic music enthusiasts world-over. He will explain the basic principles of the instrument, how it is played, and how to construct a simple one. Participants will also be invited to try their hands at the theremin. |

The Deerhorn project is aimed at creating new instruments out of the original radio Theremin concept. The main inspiration is Clara Rockmore's desire to have more than one pitch come from the theremin, to which Lev responded, "well then how would you control the volume of each tone?". Well, the Deerhorn idea is to derive amplitude and dynamics from the changes in pitch of each radio-tone, thus creating an automatic envelope for each. |
Harford Hackerspace |
Harford Hackerspace is an organization set forth to create a place for real people to collaborate on real projects in a real place. Typically these projects would be Electronics, Software, or some other type of science project. It’s a place for people who are interested in learning everything about everything. It’s also a place to socialize and make new friends. Checkout the Cornstarch Monster that Jason McMahon built at their table. Does this sound interesting to you? Then join!

Midi Synth Controller |
Essentially my project is a midi controllable FM synthesizer based on the yamaha YMF262 chip utilizing the Midibox architecture from www.ucapps.de. A pic18 acts as a brain to translate between midi and whatever communication scheme yamaha came up with for that chip. For mine I've choosen to eliminate the complicated hardware interface and control it completely over midi. I will also be showing the mods that I performed on an very old "classic tube" guitar amp manufactured by ALAMO. This amp was purchased at a yard sale for $10 in very bad shape. After looking at this "prize" I realized that it's design was based on the classic "RCA Tube Handbook". I then set out to modify the circuity to produce a better sounding amp than when it was first sold to the public by ALAMO |

Greg Kist a synthesist and festival performer (‘Project One’), will be conducting live vocoder demonstrations throughout the day. Show attendees will be able hear the sound of their voice processed by a vocoder, and learn more about the underlying technology that creates the effect. Attendees can view pictures of vocoders past and present, and hear examples of the vocoder effect used in popular music. |

Karl Ekdahl has been DIYing electronics since the late 90's and has among other things built and designed analog synthesizers, drum machines, digital interfaces (usb/midi etc) and effect units. He has also done various circuit bending and ventured into the misuse of traditional audio-electrical concepts and topologies. Currently he's running a repair shop in Baltimore City and has recently released his first commercial product, The Ekdahl Moisturizer. |
