Introduction: Interactive Reflex Punching Bag

This instructable is for anyone who wants to improve their agility and boxing skills while acquiring Sir Thomas More experience bonding, using Arduino, LED's and the MK 2125 Accelerometer.

The take aim of this project is to modify an present reflex bag and transform it into an interactive, gamified and more immersive ware. The conception I created to attain this involves embedding 4 Light-emitting diode's roughly the base of the bag, an MK 2125 accelerometer inside this base and then copulative these components to an Arduino UNO at the inferior of the stand.

- The MK2125 sensor provides tilt and quickening data which is used to shape which way the bag is organism hitting.

The LED's Clear up in a randomized cycle, which just iterates to the next Light-emitting diode when the bag is struck from the comparable / enthusiastic side. The idea behind this is to get the exploiter moving around the bag arsenic quickly as come-at-able, striking it when they find the side with the glowing LED.

A traditional workout with a reflex bag is planned to improve punch truth and timing.

After edifice and testing this device it is clear the upgraded version builds upon its predecessor, by integrating the necessitate for fast footwork / effort and sharpening the use of your visual reflexes. It has really made exploitation the reflex bag 10x more fun overly and It now feels like more of a game than an workout!

aim achieved.

I designed a chalk out in processing (arsenic shown in video + connected to this gradation) to figure exactly how the randomized LED round will work, feel free to download it from the attached files and test IT out yourself surgery fair ascertain the preview clip.

To create this product you leave ask:

  • 1x Unconditioned reflex Purse
  • 1x Arduino UNO
  • 1x 9V Battery Plurality (To power the Arduino)
  • 1x Memsic MK 2125 Accelerometer
  • 4x LED's (I have chosen Common)
  • 4x 10ohm Resistors
  • some sponge / effervesce to protect electronics
  • 1 meter of 6 substance telegraph
  • 1 meter of 2 core cable
  • about 28 jumper wires with pins
  • lots of solder and a bonding station
  • lots of heat-shrink tubing of assorted sizes
  • Canal Tape
  • Super Glue
  • Velcro (securing the wires loosely to the stand)
  • Tupperware / waterproof container (housing the Arduino + battery pack)

Whole step 1: Embedding LED's and Sensor

The precise opening move is to drill 4 holes around the walls of the bag base to embed your LED's.

each combined of these LED's should be connected to a ground wire on the - pin and a 10 Georg Simon Ohm resistor on the + stick. you will want to duct tape or heat-shrink these connections and press them hard-fought against the inside of the foot, as information technology is historic to make them equally durable as conceivable.

Directly you will penury to connect jumper wires to these connections and run over them through with holes in the bottom of the al-Qa'ida as shown in the last picture of this whole tone. Do the similar for the MK 2125 sensor, you will also ask to drill more holes in the bottom of the base to make up space for the pins and plug in jumper wires to these pins.

The alpha matter with the sensor is to fit it inside the base flat down and facing one of the LED's. This will beryllium your FRONT LED which is useful future connected for calibrating the sensor.

When all of these components are snug inside the base, you should be able to stopper the jumped pins into your Arduino and run the code (TiltSense.ino) as shown in pic 5 of this gradation. If the code works fine and all the soldering is solid, fill the gaps with a trifle of sponge / foam and tip a bit of superglue over the LED's to keep them locked in.

Step 2: Connecting the 6 and 2 Core Wires

In this step we will glucinium extending the connections down from the base of the Lucille Ball all the room down to the base of the stand with some 6 core and 2 meat wires.

The ultimate goal here is to extend all the wires down from the top of the stand to the bottom of the stand, in the most convenient and serviceable way possible.

- 6 Inwardness

The way I decided to do this was to strip the 6 core conducting wire slightly (shown in first picture) and:

  • solder the LED's + Pins to 4/6 wires (these will wa into Arduino pins 10,11,12,13)
  • solder the LED's - wires together and then to the - wire of the MK 2125 sensing element to ground both the LED's and the sensor
  • solder the + wire from the MK 2125 sensor and all of the coupled - wires to 2/6 wires (These will plug into Arduino pins 5V and GND)

remember to use heat-shrink for all soldered connections to assure the wires possess a strong integrity and can handle dangling from the top bag ground to the bottom outdoor stage base.

- 2 CORE

At this stage there should make up 2 connections remaining which are the transmission wires from the MK 2125 sensor that will send the tilt data from the purse to the Arduino. This is how we will eventually determine which direction the bulge is being hit.

  • Solder the transmission wires to each of the 2 marrow wires (These will plug into Arduino pins 2 and 3)

Once you have with success soldered complete of these connections you will involve to then solder the other last of these wires to some jumper wires with Arduino sympathetic pins (shown in the second + third picture).

Step 3: Testing the Upgraded Bag

I decided to secure all the connecting wires to the base stand with velcro to prevent them from moving around to a fault much and damaging the soldered connections.The Arduino and 9V battery pack are housed within a tupperware container, which has also been connected to the base using velcro.

If you've seed this far you should be ready and bore to test retired your interactive reflex bag. Hope you relish this instructable, I plan on making upgrades to this project in the future since I am stoked with the termination so stay keyed!.

I'm currently brainstorming ideas as to how I could create a point scoring or high-pitched score system for this device, if you think of any thinkable additions to this project delight overlook a comment or premier me.

Assume't pause to ask any questions in the comment section, I will make sure to go back to you asap.

If you likable this, delight vote for ME in the Arduino operating room Make It Glow Contests. IT would mean a deal, thanks!
