When current go through, some conductive materials will also turn warm or even hot, so I tried different kinds of materials and look for a best which can make a heating pad. The red paper will turn white when it feels hot. 1.conductive thread knitting mit common thread. resistance : about 11 Ω when voltage is […]
This is a push button. The following is the data-sheet. After the four black point was cutted, metal panel and the button cylinder were apart and there’s a round panel inside. When push the round panel, it links the metal part in the mittel and the two side metal parts. That’s how does it […]
I became very interested in the function of a speaker, specially because it sounds so simple. In this exercise I tried to experiment as much as possible with materials for the membrane and shapes for the copper spiral. My intention was to find a shape for the spiral that was different from the 2D design […]
Tilt Switch actually just work as a simple switch to make open and closed circuit. Open a tilt switch, we can see there are to conductive balls inside a copper tube. There are two pins with this switch, one connected to the outer copper tube, and another one go into the tube and which would […]
The original idea is to build a motor with soft linear material at sides which could be held and turning in hand . To build a motor you need to roll the surface-isolated wire into spiral, and its important to make sure that you make the spiral as a continual circle which means you […]
Since I took apart a potentiometer yesterday, I thought it would be fun to experiment with different conductive surfaces, like the two pathways that run along the base of the potentiometer. I worked with wood as a starting material and used a number of different materials to experiment with conductivity. I started by digging ‘canals’ in […]
This week at the Kit of No parts Workshop I opened up first of all a Sliding switch. It is a very simple mechanism, but still includes many details to think about. It is a three leg pieces that consists of a sliding conductive bridge that always makes contact with Ground (center leg), but depends […]
For my project last week I intended to play with sensors and textiles. I created a little system where you blew into a ventilator that produced a certain amount of voltage. This voltage was read by Arduino and gave a series of values depending on the intensity of the wind. When the value went between […]
The device I took apart is a Potentiometer Knob.. So let’s see how it works! It is made of a base with three legs, a slider, a screw and a top cover. Legs 1 & 3 are connected through a high resistance pathway on top of the base. Leg 2 is connected to a very […]
Pressure sensor is made like a bend sensor with a conductive thread, velostat, conductive fabric and non-conductive material. Structure of pressure sensor (click for bigger picture) Parts of the sensor: – Conductive thread : to connect threads in the circuit – Non-conductive material (neoprene) : to give the sensor structure – Velostat : […]
