Selbstspielendes Monochord mit DIY E-Bow-Elektronik. Einfache Workshopversion. Einsaiteninstrumente = [https://en.wikipedia.org/wiki/Monochord Monochorde].

Material Monochord: Kiefernstab 800mm x 20mm x10mm, Gitarrensaite, Gitarrenmechanik, Pappbecher als Resonator

== Materials ==

=== Electronic parts ===

* 1x diode 1N4148
* 1x capacitor 220uF
* 1x capacitor 10uF
* 1x LM386 (IC Dip-8)
* 1x jumper cap (2,54mm)
* 1x 3-pin header (2,54mm)
* 1x 9V battery clip

* 1x driver-coil (16 Ohm)
** Electro-Magnetic passive Buzzer: https://www.ebay.de/itm/183310696634?hash=item2aae2b40ba:g:eM0AAOSwS6pgmlev

* 1x sensor-coil (110 Ohm)
** Electro-Magnetic passive Buzzer: https://www.pollin.de/p/signalgeber-schallwandler-elektromagnetisch-digisound-f-wex-12-t-640943

=== PCB ===

[[File:singendesaite_plan.jpg|400px|thumb|none]]

PCB design by Ralf Schreiber: [[:File:Ebow_singing_stick (1).pdf]]

[[File:Ebow circuit-minimal-design (1).jpg|400px|thumb|none]]

=== Mechanical / Acoustic parts ===

* 1x guitar mechanic (tuner, peg)
** https://www.ebay.de/itm/323843278635?hash=item4b6690472b:g:i~UAAOSw5L9XD0QB

* 1x wooden stick (pine tree) 100 cm x 2 cm x 1 cm
* 1x string (piano-string on reel) 100 cm x 0,8 mm
* 2x pressure springs (shortened springs from ball-pens)
* 2x M3 Inbus screws (length 12-15 mm)
* 2x M3 tee nuts -> tinyurl.com/43nz2zdr
* 1x guitars bridge (20 mm halved round beech-wood)

=== Preparing the coils ===

The coils are electro-mechanical buzzers. one with a DC-resistance of
about 40 - 120 ohms (common value) the other with 8 - 16 ohms. this one
is a bit harder to find...

[[File:prepared_Buzzer (1).jpg|400px|thumb|none]]

If you remove the plastic casing with a pair of pliers, you get the
wrapped cores. it is important to observe the polarity, the marked coils
(+) must be installed in the same way!

I just realized that I have forgotten one important detail!
A small round neodymium magnet (3x1mm) must be glued on the core of the driver coil.
The tiny magnets are easily available everywhere!

=== Strings expertise ===

Basic knowledge about strings (in German):
https://www.thomann.de/de/onlineexpert_page_saitenkunde_akustikgitarren_stahlsaiten.html

cheap strings: https://www.thomannmusic.ch/harley_benton_valuestrings_010.htm

== Assembly ==

[[File:Ebow_assembly.jpg|400px|thumb|none]]

The adjustment of the ebow-board to the stick is a bit tricky. it is
important that the coils are positioned very close under the string (1-2
mm distance).

I use small 3 mm drive-in nuts (brass tee nuts).
So the board is spring mounted and the distance of the coil-cores to the
string can be adjusted precisely with 2 screws...

== Experiments ==

>> Is there something we could try to experiment with? improve, explore?

-> the strings can be prepared with light things: pieces of aluminum
foil, drinking straws....the woodenstick can be prepared with petri
dishes full of sand, pearls..

-> the device is also an electronic drone machine, a coax-signal cable
(with line level) can be soldered parallel to the driver coil ...

-> Multi-sided monochords or several ebows can be interconnected ...
the surfaces and conditions are decisive ... test setups with wine
glasses ??

-> the strings can become dampened and heavier... small balls patafix,
bluetec are super helpful for modulating and generating complex variable
drones

<--- Back to [[HOME MADE 2024]]

==I am coming!==

=== Ralf ===
Uwe has a new electromechanical stepper motor synthesizer in his luggage.
There will be a workshop and I will support him.
https://vimeo.com/979018025

There is also a new version of the "Singing String" ebow instrument.
It is now much shorter and easier to transport. I will bring a few workshop-kits with me.

=== @tamberg ===
* Walking there from Zürich

===Miranda and Urs===

Walking up from Wasserfallen on 27th.

Will be working on:
Amazing things with Low Energy circuits, eink displays, bioelectricity, music.

Planning for cameroon trip with Michel and solar OpenSource school, developing workshop. Topics: MPPT solar chargers, battery regeneration, esp microscope, lora, plastic recycling 3D printing, passive solar reflow soldering oven developement. Testing and troubleshooting "energy meadow" circuit. [https://github.com/m0Ssss/hybrid%20charge%20controller/ https://github.com/m0Ssss/hybrid_charge_controller/]. Gravity batteries.

Ceramics: we will bring clay and also hunt for wild clay. We need: kiln from Bitwäscherei, otherwise we experiment with fire burning or microwave firing. To make: nice things, also fun for kids, ceramic circuits with metallic glaze (silverification and goldification @gandalf), piezo materials.

Etching Tiny energy harvesting circuits for nails and earrings. Binoculars for micro soldering would be awesome.

Synthesizers geeking, jamming.

Discussion/activity: building safer spaces in tech communities

Other things we will bring/organise:

. Delicious material science vegan meat Bbq workshop.

. Distributed Yatzy tournament

. The new modular open theremin

I will bring a P.A. speakers and a Mixer and some sound stuff.

I will work on some R code to sonify environmental analysis data. work on and interested in audio related circuits. would be interested in introduction in video editing

Arrival Saturday 27.July

=== flo ,alice, linus , alba===
we are happy to join. its almost in out neighborhood and after our camping week . perfect.
i might try to work on key elements of the ondes martenot. i need a backup for my fragile tube based instrument and so i try to do research on ribbon capacitor and the magic volume bag (mica and graphite filled leather bag). oscillators are 80khz fix and 76-80kHz variable. i will use some simple stuff to test. i bring some material to work on the metallic ribbon and the aluminium armature for the caps and hopefully the ingredients for the magic bag.
maybe we bring also a tent, if we are not over-tented from the week before.
otherwise just a minimal set of tools and some sound equipment.
we will arrive by public transport.

PASAR SENGGOL

'''PASAR SENGGOL Pasar = market Senggol = nudge (Indonesian suburban night market full of chaotic interactions and people pushing around in dense loud environment)'''

We suggest a participatory art installation that is done through collaboration with people who join us throughout the days of the Camp in a workshop setting, where they learn and make basic electronic units for interactive sound art and kinetics. Collaborative practicies are very common in Indonesia, both as a need to survice but also as a deeply culturally rooted concept. We are happy to be able to invite Helmi Hardian, from Surabaya, Indonesia, as [[Hacker-in-Residence_Programme|"Hacker-in-Residence"]] to spend the summer with us in our hackerspace, Bitwäscherei, in Zürich, and join the [[HOME MADE 2023]] Summercamp by SGMK and other activities. We have been working together in Indonesia, for [https://www.hackteria.org/wiki/HLab14 HackteriaLab 2014 - Yogyakarta], and many other activites on DIY electronics and SoundArt, mostly doing workshops and PCB geeking. Besides Helmi and myself dusjagr, we will invite 3 other mentors and constructors to help us developing the art installation and support the workshops.

== Helmi Hardian (Surabaya, Indonesia) | [[BIR residensi]] ==
[[File:Helim_Ugly.jpg|250px|thumb|right|Helmi in his full beauty]]
Helmi Hardian is a grassroots artist and ghetto scientist, with a specific interest in cooking and smoking at the same time. He lives in Surabaya, the city that is well known for its industry and technology, as well as being the center of electronic component trading (chiefly, Pasar Genteng). Hence, almost all of his works are closely related to science and technology as the medium of creativity. He is the co-founder of Waft Lab, a creative-based initiative that works at interdisciplinary practices. Currently, he focuses on tech development through DIY/DIWO culture and playing his role in researching, hacking, or deconstructing daily materials to provide some devices with new functional aspects, as well as developing workshop kits, lecturing contents, and presentation materials, which aim to learn, share, and exchange knowledge.
