A ascends a route while Climber B stays on the ground and tracks Climber A`s progress with the laser pointer. The Redpointer then records exactly what route was followed. Here, the route recorded in Mode 1 is played back in real-time, projecting a laser point onto the climbing wall to illustrate the path of the previous climber as a g

host . E. g. Climber C now turns up late to the climbing session. Climbers A, B and C all stand back and watch the laser turret replay the route Climber A took when recording in Mode 1. Climber C now knows where to climb if she wants to imitate A. This mode is a combination of modes 1 and 2 and is designed specifically for competing against a previously set route. Once a route has been recorded in Mode 1, another climber can race against it in Mode 3 and be given live feedback saying whether he/she is ahead of or behind the pace set in the recording. E. g. Climber C now climbs the same route as Climber A, while Climber B uses one laser pointer to track C`s progress. Meanwhile a separate laser pointer illustrates A`s ghost on the same wall so that C can tell if she is winning or losing the race. Every time C overtakes A`s ghost or is overtaken by A`s ghost, a buzzer sounds. At the end of the route, The Redpointer indicates whether A or C won the race. There are a few serious safety issues to consider before beginning this project. Please do not skip to the next step without first carefully considering these. Rock climbing is inherently dangerous. Obviously, this danger is largely mitigated by the careful use of ropes, harnesses and other safety equipment but the danger is always present. Never go rock climbing if you are not fully competent and confident in the various techniques involved (belaying, leading, rigging, etc....
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
