<h1><b><u>Arc generator ESD test device</u></b></h1> https://youtu.be/kJc0b9foZe4 <h2><b> ⚠️ Warning! This is an electric shock device, made for experimentation! build it with precaution, print it and using this device might cause injury ⚠️</b></h2> <p><i>"Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short, or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark. ESD can create spectacular electric sparks (lightning, with the accompanying sound of thunder, is a large-scale ESD event), but also less dramatic forms which may be neither seen nor heard, yet still be large enough to cause damage to sensitive electronic devices. Electric sparks require a field strength above approximately 40 kV/cm in air, as notably occurs in lightning strikes. Other forms of ESD include corona discharge from sharp electrodes and brush discharge from blunt electrodes."</i><b>-Wikipedia</b></p> <p>I decided to design and build my own 3D printed ESD arc generator version with a charger which will cost you less than <b>10$</b> if you have a 18650 Li-Ion battery from an old laptop.</p> <p>All the parts to build one are included in the following list with supporting images from the build process</p> <h4><u>Parts list</u></h4> <ul> <li>3 M3*15mm Allen screws for the charging part</li> <li>3 M3*20mm Allen screws for the Top part</li> <li>DC 3.7-6V To 400KV Boost Step Up Power Module High Voltage Generator <a href="https://www.banggood.com/DC-3_7V-6V-To-400KV-Boost-Step-Up-Power-Module-High-Voltage-Generator-p-915426.html?p=CZ2005204372201306X4&custlinkid=918613" title="With a Title"> <b>Get it here</b></a>.</li> <li> Mini Round Black 2 Pin SPST ON-OFF Rocker Switch Button<a href="https://www.banggood.com/Mini-Round-Black-2-Pin-SPST-ON-OFF-Rocker-Switch-Button-p-911385.html?p=CZ2005204372201306X4&custlinkid=918618" title="With a Title"> <b>Get it here</b></a>.</li> <li>Momentary OFF ON Push Round Button<a href="https://www.banggood.com/Car-Auto-Momentary-OFF-ON-Push-Round-Button-Horn-Switch-Multicolor-p-927835.html?p=CZ2005204372201306X4&custlinkid=918620" title="With a Title"> <b>Get it here</b></a>.</li> <li>Momentary OFF ON Push Round Button<a href="https://www.banggood.com/Car-Auto-Momentary-OFF-ON-Push-Round-Button-Horn-Switch-Multicolor-p-927835.html?p=CZ2005204372201306X4&custlinkid=918620" title="With a Title"> <b>Get it here</b></a>.</li> <li>TP4056 18650 Li-Ion charger <a href="https://www.banggood.com/Micro-USB-3_7v-3_6V-4_2V-1A-18650-TP4056-Lithium-Battery-Charger-Module-Charging-Board-Li-ion-Power-Supply-Board-p-1633310.html?p=CZ2005204372201306X4&custlinkid=918626" title="With a Title"> <b>Get it here</b></a>.</li> </ul> <h4><u>If you don't have these parts around</u></h4> <ul> <li>Silicon wire 20 Awg -
