I have made an interesting project of a wireless rocket launcher and I hope you guys will definitely love this one.
Four-Channel relay board is used to launch four firecracker rockets one by one wirelessly or at a time without the risk of one running behind you and making sure that it's totally safe for kids too. The project is mainly divided into woodworking, apart of a workshop for cutting steel tubes, electronics, wiring, and enjoyable fireworks then after.
1) A thick almost 1.25-inch log of MDF wood for a base
2) Few 20mm wooden sticks for elevating the base
3) The four-channel wireless relay set
4) on-off toggle switch
5) Status LED and drop down 470 Ohm /resistors four each
6) Lipo Battery 3S
7) Steel tubes
8) copper insulated wires
9) Nichrome Wire for making torch coils
10) few zip ties

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Wooden Base Preparation
I took thick MDF wood to make a base for the rocket launcher. I then marked up all the drill holes to house the steel tubes later on. I drilled part holes on the top of the wooden block. I also drilled wire pass-through holes as shown in the above pictures.
Step 2: Wooden Base Bottom Part Preparation and Top Part Covering
I made slots to house electronics and battery at the bottom part of the wooden base after marking up the same. Then I covered the top part of the wooden block with resin hardener paste so that the top does not catch accidental fire due to flames exhaust from the rockets being launched
Step 3: Base Elevation and Wiring
The wooden MDF block wherein all the electronics are to be mounted is elevated on wooden strips by hot gluing the strips to the base. Also, the status LEDs and switch will be mounted on the wooden strips. Rocket torch wiring is taken up from the holes on top form through holes.
Step 4: Installing Electronics and Wiring Up
Four-channel relay board is installed at the place. Also, the lipo battery is placed at the slot made for it in the wooden base. Status LEDs with resistors are wired up as shown in the figure. Torch wires are taken up on to the top side through the wiring holes. The system on-off switch is also installed at the bottom part.
Step 5: Testing the Wireless Board and Pairing the Remote
All the electronics are wired up the lipo battery is connected and the relay board is paired with the RF remote and tested for proper operation. Also, the status of LED working is checked in this step.
Step 6: Making Fuse Coils and Mounting Arrangement
I took four bakelite connectors that do not get melted due to flames and sparking from rockets being launched. I then took nichrome wire form 1500 watt electric stove and made small coils of the nichrome wire as shown in the pictures above which will torch the rocket fuses. It will be wired up as shown in picture three.
Step 7: Installing Steel Tubes
There are two steel tubes for each rocket launch channel. One is the guide steel tube and one is carrying the wire to protect the wire from getting burnt from rocket flames and sparks. These tubes are cut according to size and then fixed on to the top of the rocket launcher in the holes made previously.
Step 8: Finished Rocket Launcher and Time to Have Some Fun
As seen in the above picture the rocket launcher has been finished and it looks something like visible in the above picture with a lot of mess in the background. It was very exciting and guys you will love watching the video of the rocket launcher in action. It performed like a charm and it was fun launching the rocket successively one after the other and some times altogether.
I hope that you guys enjoyed this instructable and I would definitely like to know your word about this project
