Make the Ultimate Bluetooth Dry Ice Fog Machine

prusaprinters

<p>I recently needed a Dry Ice machine for some theatrical effects for a local show. Our budget would not stretch to hiring in a professional one so this is what I built instead. It's mostly 3D printed, controlled remotely via Bluetooth, battery-powered, portable and includes LEDs for fun effect. You can even design your own nozzle to create different fog patterns.I've included two nozzle designs of my own for you to try.</p> <p>It works great as a stage effect and will be a hit at any Halloween parties.</p> <h3>Print instructions</h3><p>If you prefer to follow an instructional video then I have created one which you can watch. It's also great if you want to see what this machine is like - I show both types of nozzles that I designed at the beginning of the video: <a href="https://youtu.be/IhL9i5he0LY">https://youtu.be/IhL9i5he0LY</a></p> <p>Written instructions: <a href="https://www.instructables.com/id/Ultimate-Dry-Ice-Machine-Bluetooth-Controlled-Batt/">https://www.instructables.com/id/Ultimate-Dry-Ice-Machine-Bluetooth-Controlled-Batt/</a></p> <p>List of items used in this project and where to find them (the links are Amazon affiliate links and help to support this channel at no cost to you):</p> <p>■ Elegoo Arduino Nano (x1): <a href="https://geni.us/ArduinoNanoV3">https://geni.us/ArduinoNanoV3</a><br/> ■ L298N Motor Driver (x1): <a href="https://geni.us/L298N">https://geni.us/L298N</a><br/> ■ 8 AA Battery Holder (x1): <a href="https://geni.us/8aaBatteryHolder">https://geni.us/8aaBatteryHolder</a><br/> ■ AA Batteries (x8): <a href="https://geni.us/AABatteries">https://geni.us/AABatteries</a><br/> ■ Mini breadboard (x1): <a href="https://geni.us/MiniBreadboard">https://geni.us/MiniBreadboard</a><br/> ■ 12v Geared DC Motor (x1): <a href="https://geni.us/12VGearedDCMotor">https://geni.us/12VGearedDCMotor</a><br/> ■ HM10 Bluetooth Module (x1): <a href="https://geni.us/HM10Bluetooth">https://geni.us/HM10Bluetooth</a><br/> ■ Contact Switches (x2): <a href="https://geni.us/ContactSwitch">https://geni.us/ContactSwitch</a><br/> ■ Stationery Holder (x1): <a href="https://geni.us/StationeryHolder">https://geni.us/StationeryHolder</a><br/> ■ Nuts and Bolts: <a href="http://geni.us/NutsAndBolts">http://geni.us/NutsAndBolts</a><br/> ■ Wire: <a href="https://geni.us/22AWGWire">https://geni.us/22AWGWire</a><br/> ■ PLA Filament: <a href="https://geni.us/PLAFilament">https://geni.us/PLAFilament</a><br/> ■ Plastic Container (x1): <a href="https://geni.us/PlasticContainer">https://geni.us/PlasticContainer</a></p> <p>==========</p> <p>The code and wiring diagram can be downloaded from here: <a href="https://diymachines.co.uk/projects/bluetooth-controlled-dry-ice-machine.html">https://diymachines.co.uk/projects/bluetooth-controlled-dry-ice-machine.html</a></p>
