What I make is a glove that can emit light and sound. I put CPX on the wrist of the glove so that it won’t affect my normal hand movements (such as holding something). There are two unconnected spans of conductive lines at the bottom of the glove. When the two parts are disconnected, CPX will emit light. When I put on my bracelet, the two spans of conductive lines will be linked, and the light goes out completely until the circuit is disconnected again. Secondly, I also added an audio output. When the D7 button on CPX is turned on, the music will ring out. Because the bracelet will be tightly worn on the hand, there is no need to worry about the light trigger will be particularly sensitive. The connection between the two circuits will not be easily disconnected.
My idea of making this pair of night light gloves is very simple. It was completely stimulated by the long winter in Canada. I used to live in Mississauga, and at night the lights on the street were dim. It was even a power failure that occurred one winter in the whole street due to a blizzard. I can actually turn on the flashlight in my mobile phone, but it’s really cold to hold my mobile phone in my hand all the time (even if I take gloves, but to unlock my mobile phone, I still have to take off my gloves). Secondly, my mobile phone is often frozen to the point of turning it off. So I want to make a glove that can be used for lighting, simultaneously keeping my hands warm. Besides, there is also a very important reason, that is, I am deeply influenced by some movies and animation. I think that emitting lighting from hands is a very cool thing, and having a sense of future technology. Of course, I always try to add more functions to my product. The purpose of adding audio is to improve the safety of people walking alone at night. When I write the code, I try to make the music longer and the volume higher. Once someone is in danger, turn on the switch immediately. The sudden sound may make the other person shake his mind. You can take the opportunity to escape. If you are lucky, you can also attract other people to help you. Of course, this is only a rare case. The trigger of “lighting” and “alarm” functions are two completely different switches, so don’t worry that you will walk on the street and suddenly CPX will give an alarm to scare other people.
I forgot to take pictures, so I drew a step diagram.
- First, sew CPX on the gloves with black cotton thread
- Connect pin A1 and two resistors with conductive thread and sew a row of lines on the bottom of the glove. Then start at Pin 3.3V and sew to the bottom, leaving a row of lines.
- Finally, cover the Cpx and resistor with black stockings, leaving the bottom two spans of lines exposed.

Reflections & Next Steps
Although “lighting” and “alarm” two functions have been realized in my final work, they can still be improved in some ways. First of all, about the “lighting” function, I set the disconnection circuit to be “on” and the connection circuit to be “off”. However, this seems to be contrary to everyone’s habit. To be honest, I tried to set “disconnect the circuit = turn off the light”, and “connect the circuit = turn on the light”. However, there is a big problem: once the circuit is connected, the light will remain activated. Even if the circuit is disconnected, the light will only flash and will not be completely turned off. I think the most important character of “flashlight” is that it must be able to be completely controlled by people with its “on/off” status, so I finally chose the setting of “disconnection = light on, connection = light off” to ensure practicality. The second problem is that I choose to use black stockings to cover the exposed CPX, but it greatly reduces the brightness of the light. To improve my design, I think I should choose another material with strong penetration to cover CPX. After all, “lighting” is the core concept of my design.
