Actually, today practically all components of the satellite can be found in the ordinary apartment. Of course, the self-made satellite will not be able to function as real, and, moreover, you will not manage to send it into Earth orbit, but the satellite model consisting practically of the same parts as the first satellite launched in 1958, is available to each school student.
It is required to you
- - box;
- - thermostat;
- - 4 batteries;
- - fan;
- - balloon;
- - foil;
- - transmitter from the radio-nurse or phone;
- - thermometer.
Instruction
1. Find a suitable cover for satellite model – it can be a metal sphere (the first satellite was a sphere with a diameter of 61 cm), a usual iron box from cookies or tea. Lay out a box a foil from within to protect devices from sunlight.
2. You need the radio transmitter and the antenna to accept signals and to transfer them back. Use for this purpose the transmitter from the radio-nurse. Besides, this function can be entrusted mobile or wireless phone, or the Internet router.
3. As the temperature sensor take the ordinary or electronic thermometer. From it bring a signal to the switch reacting to change of parameters of the environment.
4. You need also pressure sensor, use for this purpose a balloon. At damage of the case it will be inflated and will burst. If there is an opportunity, equip the satellite with the computer program which will consider temperature change and pressure and to transform it to the signal transmitted by the transmitter. Thus, you will have an opportunity to receive signals of a condition of the satellite.
5. Do not forget about the power supply, in its quality ordinary finger-type or mizinchikovy batteries can act.
6. That the satellite did not overheat, take the fan from the computer and program it, it has to will join at achievement of the established temperature. The fan at the same time can put in action, for example, the thermostat from the washing machine, a heating system or the electric furnace.
7. When your satellite is ready, carry out control tests. Check operability of all devices, try to start. For this purpose make a rocket, having used article http://www.kakprosto.ru/kak-21420-kak-sdelat-raketu-v-domashnih-usloviyah or in a different way. It is theoretically possible to launch the satellite into an orbit, having used services of the organization which is engaged in start of satellites, but it will cost much to you enough.
