To add Safety while using fabrication tools was the theme I selected for the project. In
that I found how I can make a Safety Gear detection as majority of welder many time aviod
using safety glass shield if it is not near to them.
So I worked on creating a system which have a detection and control of power supply which will on work when the safety shield is used.
To make that I have used Push Button Switch which is connected to a Board which have Bluetooth on in and mounted on the shield. This board communicate to other which is working as power supply controller when this shield is been used. So with that signal of push button Bluetooth communicate to other device and Relay is turned on. which Switch on the device.
- Step1 : Device Detection is having a Push Button Attach to 5V which when press signal the board as High.
- Step2 : As soon the Safety Shield Board receive signal as HIGH Bluetooth send a tranmission to other board.
- Step3 : Once the Switch Controlling Board receive the signal by Bluetooth it send a output signal to Relay.
- Step4 : Relay connected to plug as switch mechnishm enable power supply for useage.
Packaging considerations and system integration
To make the shield remote and moveable packaging need to such which can be adpatable and
fitted easily on the Shield. So I designed and 3D Printed Box which will have Circuit and battery.
Other side the Box need to have plug into it with Cable going in so I used a Laser cut design on a 5 mm plywood which made that look little bit asthetic and easy to use. Inside the box I kept my Circuit and also added a step down adapter which provided 5 volt power to Circuit and relay.
