Hi, For my A Level Design Tech project I've built a punching bag that tells the user (on a scale of 1 to 8, I wanted to use PSI but it would be too complex) how hard their punch is.
It works like this. The user punches the pad, which is filled with water, when they punch it the water gets displaced and travels up a tube. At the top of the tube is a funnel and glued onto the funnel is some rings which has a latex rubber membrane screwed in between the rings.
The rings inflate because of the water displacement and on top of the rings is a ratchet which is connected to the pendulum which gives a reading and tells the user how hard they punch. Simple.
I've attempted to make it look nice by wrapping some red self adhesive vinyl around it. It's attached to the wall using a makeshift wooden stand (I hate the stand btw, but it was necessary)
Anyway what do you think, does it look good, would you use it, what do you like/hate about it, Do you think you'd buy it it it would help your training?. Obviously you can't go in depth because you're not using it but give as critical an evaluation as you possibly can, Thanks.
Here's a photo of it btw:
