Hardware hacking tools
Using transistors as Darlington pairs, it was picking up very small signals. Next is the Live wire detector, where it can detect the presence of live wires. Here my camera's shutter speed is being approximated.

The next was the stroboscope, where it uses a potentiometer to change the flickering rate i.e how fast the LED oscillates and upon matching that with a moving or rotating object, we can see the object is still and steady, by calculating the period of oscillation and inversing it, we calculate the frequency of the object. Along with that using some trigonometry, we find the exact angle. Upon tilting the board, the acceleration due to the gravity vector changes at an angle phi. The level meter was pretty straight forward it senses the inclination on the X-axis. This can also be used by painter to estimate area of faces of buildings.ĮlecTool contains an accelerometer to measure the inclination angles. The purpose of Laser theodolite was to give the electricians a rough Idea of how much wire to buy for tall buildings. And a live wire detector can be useful for measuring live wires behind walls of concealing wiring. It is an electronic tool that can measure if a surface is leveled or not, measure pretty high heights using a laser pointer, the concept of theodolites, RPM of rotating objects using the stroboscopic effect. Along with that, we took inspiration from theodolites that were used to measure very tall structures, to build the height measuring device. So we thought of incorporating a live wire detector that can sense live wires. Many times we hear during the drilling of holes in walls, humans get shocked by rupturing live wires. Hence we thought of building a hack that is an all-in-one solution for measuring requirements, which can also come in handy to beginner electricians. Being engineering students, we realized how in industries and several other aspects of work, a person and especially an engineer needs to use different tools for the sole purpose of measuring.
