On the eve of the New Year, we will consider how you can protect yourself and your loved ones when starting fireworks. The device that the Master represents is designed to launch four rockets, but nothing prevents it from being adapted to launch more rockets, or to launch a firework.
Let's watch a short video.
So, for the manufacture of the device you will need the following
Tools and materials:
MDF;
Reiki
- Four-channel wireless relay;
-Tumbler;
-LEDs - 4 pcs;
-Resistors - 4 pcs;
-Battery;
-Steel tube;
-Wire;
-Nichrome wire;
-Cable ties;
-Hacksaw;
-Drill;
- Thermogun;
Step One: Foundation
First, the master prepares the foundation. For him, he takes a thick MDF board. Makes markup on it as in the photo. Board size 48 by 15 cm. Eight holes are drilled in the board. Four, blind, for pipes and four through for mounting.
Bottom cuts two niches, one for the battery, the second for electronics.
The upper part is covered with a flame retardant.
Step Two: Wiring
The master fastens the rail around the perimeter of the base. Then he makes the wiring. Each rocket has its own pair of wires. The second ends are connected to the contacts of the wireless relay. Power will come from a lithium-polymer battery. In the circuit, the master mounts the toggle switch. Also, the master installs an LED in the circuit of each channel. They will be located under each missile and signal which missile the launch signal is currently on. After installing the electronics, the wizard interfaces with the control panel and checks the operation of the remote relay.
Step Three: Nichrome Wire
A nichrome wire will serve as a device for igniting a wick. The master cut it out of an old electric furnace. For each rocket, the master makes his own wire. The spiral will connect to the wires through the bakelite strip. The master chose this material because it will not burn from the exhaust of a rocket.
Step Four: Tubes
To mount missiles, the master cuts off and sets four tubes on the base.The master fixes four more tubes in through holes. A wire is drawn through these tubes. This tube is shorter than the first. In its upper part, a spiral is installed.
All is ready. Now you need to fix the rockets on the launch tubes. Place the wick from the missiles on a spiral. Get a safe distance and Happy New Year to everyone!
