The idea: Create a wearable toy that allow kids to send secret messages to each other in class.
Needs: A trigger that can be quickly used to activate a small LED light, and a wearable platform to wear on a wrist.
Connected to two 1.5V power supply to test the circuits and play around with the layout of the board before committing to the second prototype with onboard power supply.
The second prototype, with it’s own on board power supply and a brighter LED light, and larger trigger. It didn’t work very well since the circuit occasionally refuse to stay in contact, could be fixed with soldering iron but I don’t have that with me at the time. The switch might be defective as well (My other switch that I tried was about equally as glitched)
So at the end I decided to dumb down the whole circuit and make a switch myself, it became a lot more compact and organized, the user tap the top part of the wearable gadget to close the circuit, and light up the LED.
Things I can add to another model, making the wrist band out of soft touch plastic, giving a “feedback” to users every time you click close the circuit, and making it slimmer, and giving the user some way to tell when the light is activated.
