With the remote control at your fingertips, you are the only one to decide when and if the parachute should deploy. Ideally, in a very large open field, you can wait until after apogee to deploy the parachute. Depending on wind conditions, you can decide yourself at what height the parachute has to open. This way, you are able to determine for yourself how many

calories you want to burn chasing and retrieving the drifting rocket. Even when there is only one single tree in sight, we all know by experience that trees are rocket magnets and that your rocket will end up dangling in that tree top. When you see the rocket heading towards the tree upon descent, you may decide to NOT deploy the parachute by forcing away your finger tip from the remote control button. The easiest way to implement remote control is to use a commercially available transmitter / receiver combination. This may be the standard remote control from a plane or car if you are a RC enthousiast already. However, when using the standard hobby RC equipment, keep in mind that the range between your transmitter on the ground and the rocket may be well over 100 meters. One big advantage is that you should normally have a direct view path to the receiver in the rocket. Unless you are launching somewhere in the middle of the city center, which is not the best place. When you are not in the RC hobby yet (as in my case) and want to build a remote control deployment for your rocket anyway, this could be the solution for you. All you need are basic electronic skills like soldering and maybe measuring a voltage. The electronics are kept as simple as possible with no exotic components involved. If you are still interested, get yourself a bottle of your favourite regional beer and settle down. For the remote control transmitter /...
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.....
