"Tom Nunn demonstrates Skatchboxes" via MAKE

Great sounds, I really like this.

"Tom Nunn demonstrates the "skatchbox" a simple percussion box outfitted with contacts mics and a plethora of objects for scraping, tapping, swiping, etc. The shuffling and raspy textures the boxes make are pretty unique, certainly warranting further investigation by audio experimentalists out there."



More about Tom Nunn,

"Tom Nunn has designed, built and performed with original musical instruments since 1976, having received a B.Mus. and M.A. in music composition from the University of Texas at Austin and S.U.N.Y. Stony Brook, and post-graduate work at U.C. San Diego. His instruments typically utilize commonly available materials, are sculptural in appearance, utilize contact microphones for amplification, and are designed specifically for improvisation with elements of ambiguity, unpredictability and nonlinearity.
In addition to the nearly 100 instruments he has made, Tom has performed extensively throughout the San Francisco Bay Area for over 25 years, as well as in other parts of the U.S., Canada and Europe, both as soloist and with other musicians. "

Custom Order: Fotosis No. 007, Noise Generating Synth.

Hello world, its been some months since we have completed anything in the realm of homemade electronics. Basically we have had our world turned upside down lately, I am now living in a whole other country working at a new job and trying to do as much Fotosis related work as possible on my off time when I come back to Lyon on the weekends.

This project was a custom order that challenged us to develop several new systems, most notable a sample and hold circuit and a micro-controller based trigger pulse generating system.

There are too many controls to list individually and descriptions would be difficult because I don't think it would be possible to find similar controls on another system to compare them to. This will probably be the last time I try to make an all in one unit this complex due to the time it took to develop build, test and debug the various circuits and programs that it contains. I feel in the future it would be better to build each of the systems individually and house them in separate enclosures that could be attached to some sort of board that gives them power etc.

Anyway here it is in action Fotosis No. 007...



There are still two more sections to complete, a CV interpretation module that will take in a control voltage and convert it to trigger pulses that can be used with the trigger pulse system and also a rocker pedal that will control the pitch of the oscillators as well as several other functions.

The sound range from more conventional synth noises to full on noise as well as different patterns of beeps and tones created by the trigger pulse generator. It would be the type of instrument ideally suited to someone wishing to create strange little samples for use on their tracks or it could be used live as a bizarre noise generating unit.

So essentially I am not going to go into details regarding the technical elements because there are just too many, so please just bask in the glory of this weird and interesting creation.

Interview With The Creator of Pixelache via WMMNA

We Make Money Not Art has an interesting interview with Helsinki based Pixelache organiser Juha Huuskonen. Huuskonen is a multi-talented DJ, artist and software designer, and according to the article, also deemed one of the "Godfathers of the Finnish media art mafia". Wow!

The Pixelache 'movement' has certainly taken off successfully since its' last 6 years. There is even a Pixelache University with monthly events throughout the network.

For those of you unfamiliar, the Pixelache festival brings together media and technology creations and ideas through various events and festivals in several international cities including Paris, Montreal and New York. Like most events, there are informative seminars, concerts and related exhibits. We tried to attend the last one in Paris (Mal au Pixel) but unfortunately couldn't even though we were in the city around the same time. Let's hope we have the opportunity this year!


Here are some excerpts from the interview,
How Pixelache began:
"The first Pixelache festival in 2002 was put together in an improvised manner, with a tiny budget of a couple of hudred euros. The purpose was to bring local active people together to discuss and present experimental work that fell between the categories - not art, not design, not research, but kind of all of these at the same time. This type of work is of course shown in all kinds of international festivals (today even more than a few years ago) but the other special thing about Pixelache has been that we've focused on showing work by young, emerging creators and taking risks by showing work that is still in the concept or prototyping stage."

Pixelache in other countries:
"Our international events started in 2003, when we organised Pixelache festival in New York and Montreal. Both festivals were organised on a shoestring budget, with a lot of effort and enthusiasm from both organisers and artists. We carried most of the necessary gear and artworks as luggage, organised free/very cheap accommodation and traveled on a Greyhound bus between New York and Montreal.

The events in New York and Montreal brought together a quite unusual combination of local organisations that all had a lot of influence in planning the festival program. In addition to international guests, both events featured a lot of local artists, many of whom were later invited to Helsinki. We have maintained this way of working ever since. The model is sort of opposite to ISEA: instead of a separate international jury, the local organisations are in charge of the program, they never have to present projects that they don't consider relevant for the local context. The program decisions are aided by an on-going discussion between various partners within the Pixelache network."

Custom Order: Bar Set, Cardboard Keyboard and Cardboard Amp / Part Two...

This is the second post concerning the bar set order, we decided to throw in some little extras, a cardboard keyboard and a cardboard amp.

The keyboard is a simple enough affair as it is based on a simple circuit that involves a 555 timer chip to produce a square wave. The casing was created by laminating lots of layers of cardboard together using glue and wood screws. In the video below we are playing the keyboard into the ring modulator of one of our earlier instruments, Fotosis No. 003. The resulting sound is the effect of the square wave noise section from Fotosis No.003 being fed into the carrier input of the units ring mod. and keyboard on the main input.



The amplifier is actually three amps and three speakers in one box. The amps are LM386 chips providing 2.5 Watts each. This set up allows us to play three separate devices into the amp where each device will have its own input, volume control, amp and speaker.

Custom Order: Fotosis No. 006, Bar Set, Optical Sequencer, Egg Beater Theremin / Part One...

Connie here. We've been working on a custom order set the last 4 weeks for someone I am very close to. If anything, I wouldn't think anyone else would be capable of supporting 'fotosis' like he has with this one project. In the infancy of our little 'business', it's the friends and loved ones who help us get through the days of uncertainty; the ones who understand our simple dream and allow us to feel that for everything we make, they truly want to be a part of our growing passion and humble expertise. (FYI - I thank all our friends at the end of our blog and also through regular posts)

This set will be showcased in a local popular bar downtown that is known for weekly live music. The requirements were in keeping with our love for recycled materials and parts, as the need for the instruments to be durable to withstand euphoric drunken customers and also the respect of a handmade retro aesthetic including Meccano pieces & salvaged vintage connectors.

We really enjoyed designing and creating this interactive ensemble, something that anyone passing by would want to touch (very important) and an experienced musician could properly plug and play with.


Here is John with the specs;

The optical sequencer contains two oscillators one generating a sine wave the other a square wave. These oscillators are set up as optical theremins, their frequency being determined by three LDR's mounted on the front or the unit.

There are also a number of patch leads, permanently connected at one end to the outputs of a micro-controller. These leads can be connected to banana jacks on the front panel allowing the micro-controller to send trigger pulses to opto-couplers that reroute the frequency determining components connected to the oscillators. The time between trigger pulses is set by a value read from another five LDR's that are connected to the analog inputs of the micro-controller.



Both sound producing sections of the unit are then fed into and mixed by a passive ring modulator before amplification. The resulting noise is a random series of beeps blips and noise that you can interact with by applying lights or shadows to the eight LDR's on the control panel.

The sound producing chips I used for this build were the XR2206 (Sine Wave) and a 40106 (Square Wave).

As this unit is for public use it was important to make the controls as simple as possible so the pots are all dual pots. Example the volume also controls intensity and the filter is also square wave frequency.

The matching theremin with the Egg Beater for an aerial is a solid state unit based on a modified schematic we found online a while back.

All of the materials used to manufacture the casings were found objects like Meccano, random collected screws, bits of metal and wood also a strange French industrial on/off switch.

The whole setup runs off a single boss PSA 230, 9v DC supply.

Custom Order: Recycled Portable Theremin

Another artist and musician ordered a portable theremin a couple of weeks ago. I just recently made this one that allowed for an interchangeable aerial which means you can connect the clip to a spoon or a guitar, or say, a drum set while you're touring with your band (right leftoverking?). This handmade theremin would be similar to that one. LOK and I agreed on using a recycled theme and he wanted something durable, which is the idea - portability, ease of storage and tough.


The case is made out of recycled wood, newspaper, cracker packaging and bits of steel & aluminum and has 2 vintage knobs. John made the crocodile clip. It's a unique little instrument that I hope the new owner will enjoy experimenting with.

Interview Max Farnea / Creator of The Sound Destruction Unit

I've been admiring Max's work since (again, I know I am obsessed with them!) CDM posted about this incredible modular synth from their flickr pool back in August. Here is the "The Sound Destruction Unit" if you haven't seen it in action.



I have just conducted an interview with not only Max the creator, but also Audrey his wife and fellow artist. These two co-exist with music making, circuit bending, robots, recycled art, dancing, photography and japan. Amazing. It's an interesting and long read, it's in full over on my mog.

Here's more,

"MAX: since I was younger, in the early 80s, electronic music, video games and home computing were my first interests and I lived electronics and computer technology always with a creative point of view. I went deeper in my hobbies studying for some years electronic engineering and taking piano lessons for seven years. Thanks to my studies in electronics I went addicted to robotics and I built a mini-robot for a couple of national competitions."

"AUDREY : my interest in making art with recycled stuff has started when I was watching Max making his electronic experiments and all the junk or surplus material he left on the table. Since now I like finding shapes like faces or body parts in every plastic or metallic piece I take in my hands. After I find such shapes, assembling them is really a natural process. It’s funny when you image me into skip diving in Verona, really funny indeed, but it’s incredible how many unused things can be found simply at home. One of the most beautiful aspect of this kind of art is giving a second life to things...Watching max working on his instruments I’ve found a lot of ideas to make my robots more alive and interactive with little lights and circuits."

"MAX : More than half of my retro and vintage stuff was mine when I was child or teenager. Other hardware comes from friends or eBay bids. The line in balancing the old and new when I’m making a new instrument is always different and is traced putting the old stuff in a modern context, and if needed ignoring also the original rules on which it was based on."

I am really impressed with these two. Everything they make is done in their spare time, and not for profit (though they are both planning to sell work in the future). I wish them the best and hope that they find more avenues to show off their talent.

For Sale: Fotosis No.003

Good news everyone! We have been very busy the last few weeks working on commissioned work and as a result haven't posted anything on our Etsy shop in a few weeks, until now:-)

This instrument which we have labeled Fotosis No.003 was designed and built by Connie it was the first unit she has designed and built alone and I love it.

It is currently for sale on our Etsy shop.

In terms of functions it is identical to Fotosis No.002 only the housing and layout of the controls is different.

We are selling it for 300 US Dollars which the same price that we sold No.002 but translates into a bit less for us when you convert it into Euro. But due to the fact that we have upgraded our basic design recently and all future units will have extra features and different construction our next models will be priced a bit higher.

Fotosis No.003 is a three in one device. It contains a simple optically controlled synth, a separate noise maker circuit and a passive ring modulator all in one box. There are ten pots, two LDR's, seven toggle switches and two momentary switches all of which control the active circuits and allow you to turn on and off various effects or sections and bypass parts of the device.

This instrument is housed in a thin sided wooden box also purpose built. Most of the wiring is point to point (in a vintage style) to reduce solder board complexity. The instrument is coated in an orange tolex like material and has steel corners and aluminum trimming around the control panel, there is also a leather carry handle on the front.

The sounds produces vary from weird drones to little sequences of chirps, bleeps and beeps and also full on noise.

There are three sections, two oscillators and a ring modulator each oscillator can be used on its own or can be mixed using the ring modulator.

It can be used as an instrument on its own or as an effect that can modulate the sound of other line level devices that are fed into the input of the ring mod.

There is a video of the instrument in action at...





It measures 36 cm long by 22.5 cm wide, the control panel is sloped and is 10 cm at its highest point Fotosis No.003 weighs about 900g.

Features:

Firstly there is a passive ring modulator comprised of three jacks, input, suppressed carrier frequency input and output. There is also a bypass toggle that switches the input straight to the output. But as with most passive ring modulators the inputs and outputs are interchangeable.

Optically controlled LFO producing a pure sine wave, with frequency switching function, low and high pitch switch and a toggle that switches off the optical function allows you to control the oscillator using two pots for when you want very slow non audible sine waves used mainly with the ring modulator as the carrier signal. Just above the main controls there is a volume knob. You can interact with this sections using the two LDR's mounted on the face of the control panel using you hands or other light sources, our favorite is to use flashing bike lights, strobes or torches for weird whining tones and intense beeps.

Next is a strange square wave noise generator that consists of two oscillators interacting with one another. Screaming high pitched tones can be produced as can low fuzz like sounds when the pots are at their max or min positions, in between you find effects similar to a simple two tone sequencer changing relative to one of the pots. There is also a low pass filter and volume control.

We have been playing around with it for a while now and have still have not discovered all the possible sounds you can create. It would be perfect for anyone into Circuit Bending, dronescape music, performance art, noise art installations, DJ's or just musicians who want a device on the side that they can use as a noise wig out machine. It is capable of plenty more subtle sci-fi effects and also when effect units like delay, phase, fuzz or pitch modulating pedals are connected between the device and an amplifier the number of potential sounds you can produce grows.

None of the controls are labeled because they are often quite difficult to describe, but we will be suppling a drawing of the control panel with descriptions relating to the function of each knob and switch to get you started.

Here is a basic run down of the controls:

Oscillator 1 Top of control panel:

High / low pitch toggle switch.
LDR switching on / off.
LDR / potentiometer select.
Kill switch.
Momentary bypass kill switch.
Volume knob.

DIY Pizza Box Scratchtable via Wired/Instructables

I am a big lover of cardboard made items. This converted pizza box scratchtable is so easy and quirky.

"It turns out that if you cut a little square hole in one side of a pizza box and a circle out of the other side, then tape an optical mouse so that its sensor faces the hole, you can pin the cutout circle over the hole facing the optical sensor and use the resulting contraption to scratch digital music using DJ software."

The how-to is originally from the great Instructables site and the blurb is from the Listening Post, Wired blogs.

Deviant Synth: For all your Synth Oddities

Again something from the musicthing blog. A new synth orientated site that purports to only post about totally out their electronic oddities. Their manifesto states no "links to fansites for Kraftwerk, Klaus Schulze, Can, Tangerine Dream, Ultravox, Gay Fairy Twinkle, or any other hideous 70s or 80s funny-haircut nostalgia keyboard act.... All tech must be ODD".

The site is called Deviant Synth and I will be checking it often thats for sure. The site creator says they are looking for contributors and anyone interested with a wordpress account can add content to the site.

Yuri Landman: Experimental Luthier

I came across Yuri Landman several months ago while doing some online research into alternative guitar construction. At the time I thought information on Yuri was limited to a wiki entry on him as I somehow missed his official website hypercustom. So I was thrilled today to find a link on the musicthing blog to a pitchfork article all about this very interesting artist. The article describes the reasoning behind many of his guitars features and the logic he has applied to his instruments tuning and the materials he likes to use.

He has recently been creating unique guitars for a number of bands including one of my all time favorite groups Sonic Youth.

His guitars look amazing, I cant wait to hear the sounds these wonderful instruments produce. I love to read about other people exploring new possibilities in the realm of electro acoustic music as it makes me feel more positive about my own experiments in this area.

Brilliant Arduino Sequencer

Spotted this fantastic Arduino based synthesizer / sequencer on the make blog this morning. The official website for this project can be found here. The links include video of the device in action is well as code and schematics in case you wanted to build your own APC (Arduino Punk Console) not to be confused with the 555 Timer based Atari Punk Console (APC) which is an entirely different but totally fun weekend noisemaker project. Be sure to check out the rest of their website Beavis Audio as they have lots of other cool audio devices and effects.

I have spent hours playing around with the Arduino board since I purchased one almost a year ago today. Our first instrument an optical theremin we called Fotosis No. 001 used one to control various effects. The possibilities this simple USB cross platform micro-controller presents are almost limitless (Well not really limitless) and I love to see what lots of people around the world is doing with this great tool. I also like the fact that this device is getting the attention it deserves from websites like Make so more people can be turned on to its potential.

Downloads: Where to find all of our sound clips

I thought it would be a good idea to do a short post showing anyone interested where our sound clips can be downloaded. I use an upload service called in.solit.us from which we usually embed mp3's but if you want to download the files feel free to do so they can be found here. We release everything we do under the creative commons 3.0 license so you can remix, reuse and redistribute the files with our blessing.

Modification to the Wacky Sound Generator

Here is a little drawing of a modification you can add to the music from outer space wacky sound generator.

This was one of the first noise making units I built. Its a really simple fun little project that produces lots of cool strange sounds and has the potential to be modified in lots of interesting ways. Here is a post we did earlier regarding our own WSG housed in a cardboard enclosure.

How does this mod work? Well one of the first things you learn when studying electronics is that capacitors in parallel have their values added. So when the transistor in my circuit is open the value of capacitance that determines the frequency of the WSG's square wave is increased by 0.01uf. This translates into a lower tone being produced every time the transistor opens and a higher tone every time it closes. The frequency of open / closed cycle is determined by the inverter connected to the base of the new transistor. So instead of your noise maker making just two distinct tones there are now three or more tones to be heard. Below is a sound clip of the mod in action.

The cool thing about this modification is that you can add several of them to the WSG creating a device capable of even greater sonic madness. Just built the above circuit several times using whatever inverters are free on the CD40106 and connect them all to Q1's emitter. Vary the values of the capacitors and see what sort of noises are produced, experiment.

The only change to the WSG circuit I would recommend that you make would be to change the value of C5 to 0.01uf or 0.015uf so the values don't get so high that no audible sound is generated.

You can set it up on solderless breadboard first and connect it to your WSG using patch cords with crocodile clips.

Cigar Box Electric: Sort of

This is a simple cigar box style electric guitar I made last year using the wooden box that comes with the Electro Harmonix Micro Synthesizer as the body. The neck and bridge were just lying around my workshop in Ireland and I had nothing to do that day so after several hours of work I ended up with this weird instrument.

The scale length is shorter than the fret spacing on the neck would like but it still sounds great when played with a slide or prepared or modified with a third bridge. The hollow body gives the guitar a rather unique resonating quality that produces really interesting tones. Below is a sample of some noises I created using this guitar and our latest electronic synth / effect unit, Fotosis No. 004 there is a picture of the equipment setup at the end of the post.

The pickups are good quality single coils that were replacements I bought for my first guitar. It was not being used anymore due to the fact that it had become so modified and broken normal music was impossible to play on it, but it looked and sounded totally cool. I removed the pickups from the old guitar and cut slots into the EH Micro Synth box through which I pushed the pickups and then secured them in place wit four screws.

This instrument was a gift for Connie as was the little Danelectro Honeytone pocket amplifier that we use all the time now as a preamp.

Custom Order: Fotosis No.004: Now With Extra Knob

We have just finished Fotosis No. 004. Its a hybrid synth /effect unit that combines noise maker, ring modulator and optical theremin. It was a custom job for a friend and includes two new features that were not on the original Fotosis No. 002. There is now an extra oscillator (Extra Knob) on the square wave section and a footswitch so you can bypass the ring mod. as you would with any normal guitar pedal.

The extra knob gives the synth lots of new capabilities and seems to act a bit like a sequencer, generating a variety of interesting beeps and blips that repeat every couple of seconds. Before I would have described it as a simple noise making unit but now with this modification it has become a whole lot more interesting to me. The sound clip below is a short composition I created the other night to demonstrate some of the devices sounds.



We are constantly redesigning and improving our instruments, trying to build devices that we feel are tough enough to last a lifetime and have a sound unique enough to keep any electronic musician happy. Each instrument will be an improvement on the last exhibiting its own visual style is well as new materials and construction techniques.

Improvements to Fotosis No.004 include, tougher case now made from tolex coated 8mm pine and leather carry handle.

Below is another picture of the unit which shows the 25 Way D type connector into which you plug the footswitch.

Design: Fotosis No. 005

Fotosis instrument No. oo5 will be a hybrid guitar / synth, but not 80's keytar style. Actually it will have everything our previous instruments had with a special sort of experimental guitar added to the control panel. That means square wave noise maker section, optical theremin, passive ring modulator and a weird stringed instrument all in one. The picture on the left is my first drawing of the proposed device. I suppose it'll look and play a bit like a lap steel guitar.

The guitar has two rails running parallel to and just below the strings. These allow the player to insert a third bridge at any location they like or place a platform / fretboard under the strings on which the can mount objects to play the instrument as a prepared guitar. There will be two handmade high output pickups (similar to the ones I made for this instrument) located at both bridges. Each pickup will have independent volume control and its own 1/4" mono output to increase the experimentation potential of the device. The instrument can be played into the ring modulator and made to sound nothing like a guitar at all.

We will be starting construction in the next week or so after we catch up on our current orders and will post images of the design and construction process here.

The sound clip below was a test I did a while ago to determine what sounds would be produced by such a device. I simply plucked the strings with one hand and adjusted the controls on the square wave section of Fotosis No. 002 with the other. The embed is a bit slow give it a few seconds to get working but the file can be downloaded here if you still have trouble.



This picture is of the setup used to produce those sounds, notice the chop stick rammed under the strings. This acts as the third bridge.

For Sale: DIY Electric Guitar

Just listed my much cherished homemade electric guitar on on Ebay. You can find the listing here.(This item is now available for purchase at our Etsy Shop)

You might be wondering why we made this and why it is on this site that deals mostly with the electronic synthesis of sound but I assure you there is a good reason. You see I used to play guitar quite a bit, I used to be pretty good. But I found that as I got older I had less time to play and more exotic sounding devices started to appeal more to me.

Before I came to Lyon I built a guitar from scrap, just for the hell of it one weekend. To my surprise it sounded pretty good and people seemed to like its quirky design. So my initial plan was to build guitars for a living here in France from reclaimed materials. I built the one that is currently for sale but events conspired, one thing lead to another and we ended up with the Fotosis line of electronic instruments.

But my dream of building electro acoustic instruments isn't over. I plan to take aspects of my guitar building past and apply them to future Fotosis style instruments. They will be a fusion of guitar and synth, but not in that cheesy 80's guitar synth way, they will be very very different:-)
