+Hello! You are looking at a printed or web version of the *Field guide to salvaging sound devices*. This guide is currently being created at the (un)repair cafe in Klankschoool[^about-klankschool], and will help you in your "journey"(blergh) of becoming a hardcore hardware salvager.
+
+[^about-klankschool]: A bit about klankschool..
+
+The guide is divided in 4 chapters[^footnotes], each discussing a step in the salvaging process.
+
+1. Gathering hardware
+2. Dismantling devices
+3. Components to salvage
+4. Recipes
+
+[^footnotes]: extra context and additional notes are provided through these footnotes.
+
+## How to hack this guide
+In the true spirit of Re-Use/Re-Claim, you are hereby officially invited to make this guide your own. <span class="d-print">Grab a marker and a knife, and correct me where I'm wrong. </span> <span class="d-web"> <kbd>Ctrl</kbd> + <kbd>S</kbd> this web page and host it on your own server, or create a [pull request](theserverisdown.internetissues) for more permanent changes.
+
+## Why salvage?
+Buying new (electronic) parts and components is usually cheaper than repairing or salvaging. Even more conveniently, in the online community of DIY synthesizers, it is common practice to share a Mouser Project Cart alongside the schematics, when publishing your project, allowing forkers to buy all parts within just a few clicks. But what if that one ultra important part is no longer produced? Or you’d rather make use of all these other electronic parts that already exist?
+
+This is where *A field guide to salvaging electronic sound devices* comes into play. We’ll go trough the process of finding, unmaking and then remaking again together, using the growing pile of electronic waste[^e-waste], whilst also sometimes talking a bit about the practice of salvaging[^about-salvaging].
+
+[^e-waste]: The pile of e-waste grows at the same rate as technological innovation does, as every product update makes it older brother outdated and read for replacement.
+
+[^about-salvaging]: Salvaging, as Jennifer Gabrys describes it, is not only about the transforming discarded materials into valuable resources, but also about “engaging with the conditions that led to the dispair in the first place” (@instituteofnetworkculturesDepletionDesignGlossary2012). moet hier nog een juiste chapterdoen
+
+### Do It With Others (DIWO)
+This field guide is created during and around unrepair nights held at Catu (where you are very much invited to!). Here, we try and figure these electronics out together. Because, electronics is super difficult, and it’s advised to thread these quests together.

+When salvaging components, we are looking for abandoned hardware. Hardware that is still fine on the inside, but no longer deemed as functional by its previous owners[^no-longer-functional] in our consumer culture. These devices can be a literal goldmine[^goldmine] of working parts that could be repurposed, as their hardware probably exceeded their stylistic obsolescence[^stylistic-obsolescence].
+
+[^no-longer-functional]:The spectrum of "still fine" and "no longer deemed as functional" is very wide. Think about printers for which their specific cartridges are no longer produced, Blu-ray players, the E.T. game that was buried, that iPhone 8 with a bad battery, Spotify's "Car Thing", etc.
+
+[^goldmine]: <ins>Something about the metals/minerals to be found</ins>
+
+[^stylistic-obsolescence]: **stylistic obsolescence** The idea that objects can go out of fashion the idea, and therefore needed to be replaced every season (@sterneOutTrash)
+
+
+
+I’ve identified 3 strategies in gathering the electronic hardware. 
+
+##### 1. Browsing the streets
+I feel like with great waste “comes to you”. Keep your eyes open, look around. Actively going on waste walks has not been very fruitful for me. The success is dependent on where you live and the waste regulations and activities[^waste-activities]. Information about waste management should[^should-be-communicated] be communicated via the municipality[^unbinair-waste].
+
+[^unbinair-waste]: <ins>Hier de Unbinare tekst gebruiken mbt hidden waste en de verandering hierin. En ergens heb ik ook een andere tekst gelezen over het verstoppen van waste streams</ins>
+
+[^waste-activities]: In Rotterdam, there are various Whatsapp & Facebook groups exchanging geo loctions for great trash.
+
+[^should-be-communicated]: The municipality waste guide website & app of Rotterdam is not functioning and has not been updated since 2022.
+
+##### 2. Donations from friends & family
+As you’ll enthusiastically keep your friends & family in the loop about your salvaging endeavours, you’ll notice the phenomenon of donations. A large portion of our replaced computing devices still reside in our storage units, waiting to be of any value (@gabrysDigitalRubbishNatural2011). hier moet nog eenpagina nummer bij
+<ins>Ik zou eigenlijk nog wel meer willen weten over waarom we zoveel devices bewaren</ins>
+
+##### 3. Institutional discards
+Institutions where electronic hardware is not their day-to-day business usually[^usually-solution] do not have a systematic solution for their e-waste. Many have a system in place to replace their hardware (printers, computers, etc. ), every 5 years. The remainders are put in storage.
+
+[^usually-solution]: <ins> Is dat zo of denk je dat maar?</ins>
+
+<ins>Hier en donations from friends & family heeft ook nog iets te maken met een soort greenwashing/shift in responsibility, maar dat nog niet helemaal kunnen duiden. </ins>
+
+
+## Salvaging vs. Hoarding
+
+When inspecting a device for salvage possibilities, I try to imagine what the inside of the device looks like. What kind of components might I find? Are there any motors or moving parts? What kind of material is the device made off? What time period is it from? Which companies manufactured the device and it's parts? Do I see any use for it now? If I don’t expect much, I’ll leave it for the next person to salvage.

+### Some tools for opening devices
+![Illustration of the tools](https://placehold.co/600x400?text=Illustration+of+the+tools)
+
+For this, the following tools are recommended:
+
+- A set of screwdrivers
+- A plastic “thing” (e.g. a plectrum, or a dull plastic knife)
+- multimeter
+-
+Dependent on your device, additional specialty tools might be required, such as:
+
+- A hot air gun
+- A drill/dremmel/saw to cut away plastic
+- Apple's 10k repair tools
+
+## Opening the device
+In some cases, product manufacturers provide service manuals[^repair-manual]. These service manuals contain valuable information that can help you to understand the device and to take it apart. Unfortunately, most of the devices I’ve taken apart did not publish their service manuals, meaning we have to figure it out ourselves. Luckily, there are online communities that create their own dismantling guides[^lack].
+
+
+[^repair-manual]: ![Preview of the manual](/assets/chapters/2/trouble-shoot.png) [This](https://elektrotanya.com/panasonic_rs-768us.pdf/download.html#dl) repair manual that passed the Repair Club contains a schematic, disassembly information, parts list and multiple trouble shouting guides.
+
+[^lack]: [IFixIt](https://ifix.com/) is known for their teirdown guides online, and work in the Right to Repair movement.
+
+Let’s take a look at the device. Do you spot any screws? They might be hidden behind stickers noting you that you are now voiding your warranty[^warranty]. I found it helpful to follow the seams of the material of the device since, especially with plastics, it’s not just screws holding your device together.
+
+[^warranty]: These warranty stickers are not always legally binding. [^warranty-source]. Plus, do you have the receipt for something you found in the bin?
+
+[^warranty-source]: Aragon, N. (2024, December 17). Warranty Void Stickers: Are they legal outside the US? iFixit. https://www.ifixit.com/News/74736/warranty-void-stickers-are-illegal-in-the-us-what-about-elsewhere
+
+If you’ve managed to get a gap in a seam somewhere, stick a thin plastic “thing” in there and carefully push it along the seam. There might be tiny tabs holding the parts together. If the manufacturer really didn’t want you to get in there, they’ve glued it all up, and it is impossible to get in the device without causing permanent damage [^black-box]. A hot air gun could help to dissolve the glue (I’m afraid of melting plastic), or you could cut out the plastic using a knife or drill.
+
+This process really is about finding small gaps in the enclosures[^black-boxism], until you’ve dismantled the entire device. Did you manage? Amazing! You're now looking at all of the inner bits and pieces of your device, made up of all kinds of materials [^inside]. 
+
+[^black-box]: These glued up personal devices are clearly not made to be opened. They are black boxes by design, designed to become obsolete @hertzZombieMediaCircuit2012. <ins>verder over black boxes (maar miss op een ander punt, bijv. bij een device specifiek)</ins>
+
+[^black-boxism]: slowly removing the outer layer of your black box, revealing the inner mechanisms.  
+
+[^inside]: The inside can tell you more about the time the device was made in. For instance, I mostly find aluminum and iron type materials on the inside of older machines. 
+
+<ins>Dit verhaal gaan ondersteunen met illustraties/foto's </ins>
+
+<ins>Maybe a suggestion to be discarded, but I would find it fun if the found devices could have a little fictional backstory -- like the airport game: 'I imagine this person (device) did this and this'. On the one hand maybe that's not what you're going for at all, but on the other hand I feel like it could a way to still acknowledge a device's history even when unknown, and in that way exercise the running theme of circulating tech.
+</ins>
+
+## Hardware to look out for, or to avoid
+
+In retrospect, i'll write here something about what to look out for and what to avoid. 
+Something about educated guessing what is inside?
+
+
+<ins>Feedback: It might be fun and insightful to add a step-by-step example of opening a device. I don't mind the longer text so much, but so far this guide has had a pretty fast pace!</ins>

+Once you've uncovered the PCB[^PCB] and other loose parts of the device[^parts], we can try to identify the various components. In general PCB's are made with either "trough hole" (THT) or "surface mount" (SMD) components. SMD components are _extremely_ tiny[^tiny] and soldered _on top of_ a PCB. Due to their size, they are really difficult to handle. Their size makes it difficult to read any type of value notation, and actually soldering SMD components is such a frustrating process.[^collapse-OS]. THT components are bigger and have "legs" which are pushed trough holes drilled in the PCB, making them easier to solder & desolder.

+How to Build a Paper Circuit PCB
+
+Paper circuits use thick paper or cardboard as a base instead of traditional fiberglass PCBs. The conductive traces are made with copper tape, aluminum foil, or conductive ink. Inspired by Ciat-Lonbarde’s designs, this method allows for flexible, handmade circuits that are easy to modify and repair.
+
+To make a paper PCB, start with a sturdy sheet of cardstock. Print or draw the circuit layout onto the surface. Lay down copper tape along the traced paths, ensuring clean connections at intersections. If using aluminum foil, glue it down with conductive adhesive or attach components with eyelets. Soldering directly onto paper is possible but requires low heat and quick contact to avoid burning. For durability, add a layer of clear tape over the traces to prevent oxidation. Finally, secure components with tape or conductive paint, creating a rugged yet flexible circuit ready for experimentation.

+Dear reader,
+
+This web page includes the WIP version of my thesis. For (limited) information about Klankschool's repair cafe, go to [https://unrepair.klank.school](https://unrepair.klank.school)[^server-down]. The text you'll find below is a draft of the thesis. This thesis will be a field guide to salvaging electronics to make sound devices. This field guide is compact and is meant to be taken "into the wild".
+
+At the I'm leaving notes for myself of things i'd like to include later. These notes can be recognized by their <ins>`<ins>` tags </ins>.
+
+[^server-down]: At the moment, the klank server is down. As far as I understand, there is an issue with the amount of electricity the server is hoarding.

-This circuit converts a 9V power source into a stable 5V output, suitable for powering low-voltage circuits like microcontrollers, sensors, and small audio devices. It ensures a clean, regulated voltage with minimal noise, preventing fluctuations that could interfere with sound circuits.
+Not the most exiting circuit, but a good way to discover how paper circuits work, and get some soldering practice. Some chips, mostly op-amps, require a negative voltage, which does not come out of a battery by default. This circuit provides you with the range of -9V to +9V, and ground. Or, if you'd like, 0V to 18V, which will come of use in the [[SingleTransistorOSC]].
 
-Instructions:
+illustrtie mbt 0v 9v range
 
-Prepare Components: Gather all components and ensure they match the schematic.
+![Since this power supply will be tossed around during any of the upcoming recipes, I made it a bit more permanent by glueing it to a piece of wood.](/recipes/power-supply/photo.jpeg)
 
-Place the 7805 Regulator: Position the 7805 with its flat side facing you. The left pin is input (9V), the middle pin is ground, and the right pin is output (5V).
+For the -9V, GND & +9V outputs I'm using conductive[^conductive] nails. In future recipes you can hook up other circuits to these nails using alligator clips[^alligator-clips].
 
-Add Capacitors: Connect a 10µF capacitor between the input pin and ground, and another between the output pin and ground. These smooth out voltage fluctuations.
+[^conductive]: You can test this using the *continuity* mode on your multi meter, which beeps if electricity can pass trough.
 
-Install the Diode: Place the 1N4007 in series with the power input to prevent accidental reverse polarity damage.
+## About the circuit
-
-Connect Power: Attach a 9V battery clip or a DC jack to the input.
-
-Test Output: Use a multimeter to verify that the output is a stable 5V.
-
-Mount on PCB or Paper Circuit: If using a PCB, solder components as per the schematic. If using a paper circuit, glue aluminum or copper tape for traces and attach components using conductive paint or wire bridges.
-
-Final Check: Before connecting sensitive circuits, double-check polarity and voltage output to avoid damage.

-This circuit converts a 9V power source into a stable 5V output, suitable for powering low-voltage circuits like microcontrollers, sensors, and small audio devices. It ensures a clean, regulated voltage with minimal noise, preventing fluctuations that could interfere with sound circuits.
+This circuit provides -9V[^negative-volt], 0V/Ground and +9V outputs, by combining two 9V batteries. If your project requires it, you can use any kind of battery instead of the 9V one, as long as they're two of the same [^18V].

-Instructions:
+[^18V]:  You can also get 18V: treat the -9V pin as 0V, making the 9V pin 18V

-Place the 7805 Regulator: Position the 7805 with its flat side facing you. The left pin is input (9V), the middle pin is ground, and the right pin is output (5V).
+In theory, you could skip the capacitors and resistors and just connect the batteries together. However, they help filter electrical spikes, making the output smoother[^smooth].  
+
+[^smooth]: ![filtering electrical spikes](/recipes/power-supply/filtering.png){ height=7px }
+
+Before plugging in the battery's, you could triple check your connections[^continuity]. When the batteries are plugged in, your pins should read -9V and +9V[^volt-meter].
+
+[^volt-meter]: Test this by using the volt meter on the multimeter. One probe touches your ground pin, the other the pin you'd like to test.
+
+[^continuity]: You can test this using the *continuity* mode on your multi meter, which beeps if electricity can pass trough.
+
+#### Upgrade
+An upgrade that could be useful is adding a power switch and LED to indicate the ON/OFF state of the power supply.
