 The artistic contributions are each stored on a Wifi microcontroller, which is connected to a scooter and is thus supplied with power as soon as the scooter is rented. To view the works, you connect to the local unencrypted WiFi network sent by the Wifi chip. A web portal opens automatically, where the work can be viewed. No mobile data connection is necessary. All works have been specially optimised by the artists to be viewed on smartphones.
-OPENCOIL is in no way associated with the "micro-mobility services", but only uses the existing scooter network. The conversion of the scooters into an exhibition space is completely reversible after the exhibition ends and in no way restricts the conventional use of the scooters (even during the exhibition).

 ## In(tro)duction
 This archive contains the files and instructions to create your own rolling  'offline'<sup>1</sup> wifi gallery space utilising shared scooters outfitted with induction wireless charging pads.
 The files presented here have been collected for the OPENCOIL speedshow that explores the impact of these 'micro-mobility services' on urban space by sharing the same decentralised infrastructure<sup>2</sup> for an exhibition space that attempts to address the conditions, effects and affects of these infrastructures.
 The artistic contributions are each stored on a Wifi enabled microcontroller  attached to a scooter in a non invasive nor destructive manner. To view the works, one connects to the local unencrypted WiFi network advertised by the Wifi microcontroller. When connecting using Apple<sup>3</sup> devices, a web portal opens automatically, showing the work, no mobile data connection necessary. All works have been specially optimised by the artists to be viewed on smartphones.
 OPENCOIL is in no way associated with these micro-mobility services, but merely shares the existing scooter network. The conversion of the scooters into an exhibition space is completely reversible and in no way restricts the conventional use of the scooters (even during the exhibition). The scooters will not be damaged.
 The exhibition will start on October 26th in the public space in front of Zentrum für Netzkunst (Haus der Statistik). For one week, until November 1st, the exhibition will be serviced and kept running daily by our team. Should a work be damaged or not be found, please send an e-mail (service@opencoil.show) or use the Telegram App (https://t.me/opencoil)

 1. As in 'offline art' by Aram Bartholl based on the PirateBox initiative.
 <br><br>
 2. A certain branch of micro-mobility services deploy 'dock-less' sharing vehicles, meaning they don't need to be rented from nor returned to a designated parking spot. This raises questions on convenience, maintenance and use of public space. This 'decentralisation' is reflected in the company itself, where various responsibilities are outsourced; renting is done via a centralised API, repairs are done in a centralised warehouse, units are recharged by a fleet of roaming 'juicers' (lime) or 'hunters' (voi) or 'rangers' (tier) as gig work/minijob), carbon offset and recycling responsibilities are outsourced to external companies (for example: climatepartner.com and deutsche-recycling.de).

Alternatively you could repurpose 'adaptor coils' advertised to convert non-QI phones to wireless charging, such as [these](https://www.pearl.de/mtrkw-9811-qi-kompatible-receiver-pads.shtml)*. 
 **NOTE**: Be aware that these 'adaptor coils' could contain additional circuitry that condition the output for use with specific mobile phones (the pearl.de ones do). Below is a guide to modify the 'pearl' coils to deliver maximum voltage (5v)constantly, instead of switching to low power, 2.5v output when not enough/too much current is drawn.
 ### Modding 'adaptor coils'
 If you have soldered all components together and your ESP12f won't boot, you might have to modify your charging coil+circuit a bit. To make sure it's the coil, measure the output of the coil's electronics on the + and - (GND) terminals. If your multimeter reads ~2.5 volts you need to modify the circuit. (Disclaimer: the exact details on how this circuit works are yet unclear, comparing to a working coil revealed several differences in the electronics, matching them up made the non working coil output the needed 5v). 
 ##### Step 1
 You need to desolder two IC's/ chips following the (visual) guide below. The electronics and coil are sandwiched between two layers of foil. To peel the foil away look for an opening near the lightning connector.

 ![picture](https://git.vvvvvvaria.org/then/opencoil-paracity/raw/branch/master/electronics/coil-mod/002-peel.jpg)
 You are then left over with the bare coil and flexible pcb. Here I already desoldered the lightning connector flex pcb.
 ![picture](https://git.vvvvvvaria.org/then/opencoil-paracity/raw/branch/master/electronics/coil-mod/003-bare-coil.jpg)
 Remove the following chips indicated by the following silkscreen printing:
 * Q3 (chip markings: p7)
 * Q4 (chip markings: wsc7)

 ![picture](https://git.vvvvvvaria.org/then/opencoil-paracity/raw/branch/master/electronics/coil-mod/005-q4.jpg)
 A hot air reworking station + tweezers will make quick work of that (settings: 1 second on 320deg, moderate airflow). Without hot-air you could try a soldering iron or fine wire-cutters to simply cut away the chips. The flexible PCB is very fragile though.
 ![picture](https://git.vvvvvvaria.org/then/opencoil-paracity/raw/branch/master/electronics/coil-mod/006-hotair.jpg)
 Step 1 completed!
 ![picture](https://git.vvvvvvaria.org/then/opencoil-paracity/raw/branch/master/electronics/coil-mod/007-hotair-done.jpg)
 ##### Step 2
 With both chips removed, you have to bridge two of the three (now) bare connections of the transistor Q4. I could not find a datasheet on this transistor so please refer to the photo's to see which pins.

 <h1>paracity gallery</h1>
 <h2>diy howto v0.41</h2>
 <p><img src="pcb-ass.jpg" alt="" /></p>
 <h2>in(tro)duction</h2>
 <p>This archive contains the files and instructions to create your own rolling and roaming wifi gallery space (ab)using micromobility scooters outfitted with a wireless charging pad for your phone.
 These files are collected for the OPENCOIL speedshow that explored the impact of micro-mobility services on urban space by using its decentralised infrastructure as an exhibition space, while also addressing the conditions and effects of this infrastructure.</p>
 <p>The artistic contributions are each stored on a Wifi microcontroller, which is connected to a scooter and is thus supplied with power as soon as the scooter is rented. To view the works, you connect to the local unencrypted WiFi network sent by the Wifi chip. A web portal opens automatically, where the work can be viewed. No mobile data connection is necessary. All works have been specially optimised by the artists to be viewed on smartphones.</p>
 <p>OPENCOIL is in no way associated with the "micro-mobility services", but only uses the existing scooter network. The conversion of the scooters into an exhibition space is completely reversible after the exhibition ends and in no way restricts the conventional use of the scooters (even during the exhibition). The scooters will not be damaged.</p>
 <p>The exhibition will start on October 26th in the public space in front of Zentrum für Netzkunst (Haus der Statistik). For one week, until November 1st, the exhibition will be serviced and kept running daily by our team. Should a work be damaged or not be found, please send an e-mail (service@opencoil.show) or use the Telegram App (https://t.me/opencoil)</p>
 <p>Now do it yourself!</p>
 <h2>hardware</h2>
 <p>In this Archive you will find a 3d printable .stl file that will allow you to print a mould for vacuumforming the charging pad cover.</p>
 <h2>software</h2>
 <p>In this Archive you will find an arduino sketch for the ESP8266 wireless chip. </p>
 <h3>prerequisites</h3>
 <p>This guide assumes you have a 4MB ESP12F microcontroller and use Arduino IDE.</p>
 <ul>
 <li>Board Manager: You will need to add the support for this board to your IDE (Arduino in this case), see: https://github.com/esp8266/Arduino</li>
 <li>SPIFFS: You will need to add SPIFFS file upload support to Arduino if you want to upload files to the ESP12F, see: https://github.com/esp8266/arduino-esp8266fs-plugin</li>
 </ul>
 <h3>uploading Code</h3>
 <p>For ESP12F use the following settings in Arduino IDE</p>
 <ul>
 <li>Board: Generic ESP8266 Module</li>
 <li>Builtin Led: 2</li>
 <li>Upload Speed: 921600</li>
 <li>CPU Frequency: 80 MHz</li>
 <li>Crystal Frequency: 26MHz</li>
 <li>Flash Size: 4MB (FS:3MB OTA: ~512KB) </li>
 <li>Flash Mode: DOUT</li>
 <li>Flash Frequency: 40MHz</li>
 <li>Reset Method: dtr (aka nodemcu)</li>
 <li>Debug port: Disabled</li>
 <li>Debug Level: none</li>
 <li>LwIP Variant: v2 Lower Memory</li>
 <li>VTables: Flash</li>
 <li>Exceptions: Legacy (new can return nullptr)</li>
 <li>Erase Flash: depends on if you want to change SSID, Files, or only Sketch</li>
 <li>Espressif FW: nonos-sdk 2.2.1+100 (190703)</li>
 <li>SSL Support: All SSL ciphers (most compatible)</li>
 <li>Port: depend if u are uploading Over The Air, or using a cable</li>
 <li>Programmer: AVRISP mkII</li>
 </ul>
 <p>These settings give you about 2.471 KB of SPIFFS storage space for files and ~512KB sketch size</p>
 <h3>Uploading Data to SPIFFS</h3>
 <p>The website served on the ESP8266 lives in the 'data' folder inside the sketchyour sketch. To upload this data you need the 'Arduino ESP8266 filesystem uploader' plugin. Find it <a href="https://github.com/esp8266/arduino-esp8266fs-plugin">here</a>.</p>
 <p>You will find the tool/function in Arduino &gt; Tools &gt; ESP8266 Sketch Data Upload (make sure the directory path is correct). Close the Serial Monitor prior to uploading data.</p>
 <h3>over the air (OTA) uploading</h3>
 <ul>
 <li>Connect to the hotspot created by the ESP12F.</li>
 <li>Launch Arduino, choose "esp at 192.168.4.1" as the port. </li>
 <li>If you don't see the port listed in Arduino (Tools &gt; Port), restart Arduino IDE.</li>
 </ul>
 <p>You can upload your sketch and files wirelessly, there is one caveat: SPIFFS file uploads don't work with password protected uploads (line 42). Workaround: flash your sketch with line 42 commented out. Upload your files to SPIFFS, then uncomment the line and Upload the code.</p>
 <h2>electronics</h2>
 <h3>bill of materials</h3>
 <ul>
 <li>PCB: Send the gerbers from this repo to your fab of choice.</li>
 <li>ESP12F: Widely available.</li>
 <li>AM1117 3.3v Regulator: Widely available.</li>
 <li>QI compatible wireless charging coil delivering 5v and &gt; <a href="https://docs.ai-thinker.com/_media/esp8266/docs/esp-12f_product_specification_en.pdf">500 mA</a>: For example <a href="https://aliexpress.com/item/4001154059743.html">this</a>, search keywords: "pcba receiver module qi". There are also products to convert older model to wireless charging for example <a href="https://www.pearl.de/mtrkw-9811-qi-kompatible-receiver-pads.shtml">these</a>, their extremely cheap build quality allow you to easily take out and appropriate the actual charging coil + needed electronics.</li>
 </ul>
