I am thinking about that in our daily life, when we encounter something that makes people angry, is there anything that can carry our anger and release the anger?
I made this demo which called angry iron fist. You only need to spend half an hour to make this glove like me. Believe me, it is definitely worth your time to make this!

With each quick fist-punch, the anger value will gradually be accumulated and there will be a sound effect of the fist. The higher the anger value, the faster the speed of the aura will be. When the anger value reaches the peak, waving the fist again will make an explosion sound.

Step 1: What We Need

Hardware
1 x Seeeduino nano

1 x Grove-Shield for Arduino Nano

1 x Grove-RGB LED Ring(20-WS2813 Mini)

1 x Grove-Mp3 V3 -Music Player

1 x micro SD Card

1 x speaker

1 x Grove - 6-Axis Accelerometer&Gyroscope

1 x Battery

Many grove cables

Structural

3mm thick acrylic board

1 x glove

some glue

some heat shrink tube

Tool

Hot melt glue gun.

Electric soldering

Iron laser cutter

Step 2: Draw and Design CAD

Here you can design drawings based on the actual size of your gloves, or you can use the CAD file I have created.

Step 3: Laser Cutting

Then we need to cut the the board by using laser cutting. If you don't have a laser cutting at home, you can find some in the hacker space near from you easily. If there's n o hacker space nearby, you can try the Laser Cutting Servicesupply by Seeed.

Step 4: Transfrom the Battery

Since our battery is two ports, in order to link to seeedunio nano easier, we need to make a small modification to transfrom the battery to Grove interface.

Firstly, we should cut the port of battery and the port of Grove line

Secondly, we use red wire to red wire and black wire to black wire to solder them

Step 5: Software Work

Step 6: Hardware Connecting

Connect the hardware as shown below:

Step 7: Build Up

This work is actually being modified while trying many different solutions. Now this version is also a bit rough, and a more refined version will be produced in the future. I hope everyone will like it.
