Check out this pet fire-breathing dragon project for all your robotic animal companion needs. The head should make for some good pictures come Halloween, and is a good example of how repurposing off-the-shelf items can sometimes be just what is needed for a project. Watch the ignitor in action and see the head spewing flames in the two short videos embedded below. The finishing touch comes in the form of bright red LEDs in the eyes, which give the head a bit more life. also gave the mouth area a heat-resistant barrier made from generous layers of flame-blocking mortar and sealants from the hardware store. Tip - try using an egg carton or experimenting with other items. To help avoid a meltdown, the dragon breathes fire only intermittently. Step 1 - Set one cup aside for the dragons head. The dragon head is made of acrylic, and if exposed to enough heat acrylic will first melt, then burn. The two combine at the Dragon’s mouth, where the flame originates, but the electrical components are otherwise isolated from the gas elements as much as possible. Ignition is done with the help of a spark igniter that fires up on demand, fed by a high-voltage ignition coil. The flow of propane is limited by a regulator (which keeps the flame short and fixed), and controlled with a gas-rated 12 V solenoid valve.
The fire comes from a kind of propane torch sold as a weed killer set, which looks a little like a miniature tiger torch. Spark from high-voltage ignitor, right at the torch opening. It started with an economical wall-mount dragon’s head, combined with a variety of off-the-shelf components to become something greater. Adhesives: Contact Cement, 3M Super 77 Spray, Elmers Spray Adhesive, Duct Tape and LOTS of hot glue.Halloween is looming, and decided that an ideal centerpiece would be a flame-spitting dragon’s head.Foam Factory has great prices, variety and you can get it in red or white to make painting easier:.EVA Y-20 Foam (aka Cross-linked Polyethylene Foam or X-linked Polyethylene Foam).Dragon head design: Articulating wings: Duct tape dragon scales: Materials: Tons of foam, glue and cardboard. In the spirit of Instructables, I tried to fine tune and improve/optimize designs instead of straight copy/paste use. I want to give credit up front to fellow creators who helped with starting ideas.
