This work describes the implementation of an RF based wireless charging system using RF transmitting and receiving modules. The objective of this work is to implement a system that has the ability to interact and communicate wirelessly within short range. This mobile wireless charging switching system consists of two sections, the transmitting and the receiving section. Each section was interfaced to 433MHz transmitting and receiving modules. The transmitter section of the wireless mobile charging system sends bursts of 433MHz signal through push button switch which is used in the initiation of the charging process to the receiver; when this signal is received by the receiver, it activates a relay which in turn switches on the internal power that comprises the backup battery, DC-to DC converter via a Universal Serial Bus (USB) port to the mobile device to begin charging. This work was able to achieve a wireless transfer of power for distance of about one metre between the transmitter and the receiver.Keywords: wireless charging, radio frequency radiation, electromagnetic induction, inductive coupling, microcontroller,

Alat Pelontar Bola Tenis dapat mempermudah pelatih dalam menerapkan ball feeling pada atletnya. Pelontar bola tenis di kontrol oleh mikrokontroler Arduino Mega 2560 menggunakan bahasa pemograman C, yang dikontrol adalah motor DC, motor stepper beserta rangkaian lainnya. Pengaturan kinerja motor agar bekerja sesuai yang dibutuhkan digunakan beberapa komponen seperti Push Button, Switch, dan Potensiometer. Alat ini juga menggunakan 2 buah sensor yaitu ACS712 sensor arus, dan Sensor Tegangan ZMPT101B yang digunakan dalam pembacaan arus beserta tegangan pada motor. Hasil dari Alat pelontar bola tenis adalah dapat melontarkan bola tenis dari arah kiri, kanan, atas, tengah dan bawah.

This customer satisfaction survey machine was created to facilitate the survey process that will be used in the framework of the feedback process. This feedback is used as an evaluation material to continuously improve servants. This machine is made of Raspberry Pi as a mini personal computer (PC), which is equipped with a push button switch button as a survey input, as well as a 32 inch TV screen as a display. The programming language used is python, with Graphic User Interface (GUI) using Tkinter programming. From the survey engine, it can be seen a report on the number of respondents taking the survey. In addition, this tool can record survey data and present it in graphical form as a report.

We have recently completed a newly designed 650KV electron microscope. An external view of this advanced instrument is shown in Figure 1. A symmetrical Cockcroft-Walton circuit has been adopted as the high voltage generator. The cathode is heated by high frequency power; a battery is not employed. The high voltage stability is better than 1 x 10-5/min.The sectional diagram of the column shown in Figure 2 is 420mm in diameter and 2750mm in height. The illuminating system consists of a double condenser lens and a magnetic alignment device. Dual deflector assemblies for dark and bright field images, selectable by push button, are built beneath the condenser lens. Two selectable stigmator power supplies are also provided for dark and bright field image operation.

Small angle electron scattering (SAES) has been used to study structural features of up to several thousand angstroms in polymers, as well as in metals. SAES may be done either in (a) long camera mode by switching off the objective lens current or in (b) selected area diffraction mode. In the first case very high camera lengths (up to 7Ø meters on JEOL 1Ø ØCX) and high angular resolution can be obtained, while in the second case smaller camera lengths (approximately up to 3.6 meters on JEOL 1Ø ØCX) and lower angular resolution is obtainable. We conducted our SAES studies on JEOL 1ØØCX which can be switched to either mode with a push button as a standard feature.

Minuman kopi diminati oleh hampir semua golongan masyarakat saat ini sebagai gaya hidup seperti tempat berkumpul, tempat mengerjakan tugas atau sebagai tempat rapat rekan bisnis di kedai kopi. Di zaman modern ini, seiring dengan tingginya kesibukan masyarakat dalam dunia kerja banyak orang yang dituntut untuk melakukan tugas atau pekerjaan dengan cepat dan tepat waktu, sehingga mereka akan sangat sibuk dan kebanyakan dari mereka memanfaatkan waktu istirahat yang sebentar untuk menikmati secangkir kopi. Prototipe yang dirancang pada penelitian ini merupakan sebuah alat yang bekerja berdasarkan push button. Kondisi push button memiliki beberapa tahapan. Tahapan tersebut meliputi ketika tombol ditekan maka servo akan bergerak untuk menuangkan gula dan kopi. Tahapan berikutnya air panas akan mengalir melalui pompa air dari pemanas air ke dalam gelas dengan menggunakan selang. Prototipe ini dapat berjalan dengan baik dengan 3 buah tegangan input 5V dan arus 2A untuk Arduino, 12V dan arus 2A, 220VAC untuk pemanas air.

Eight channel wireless intelligent responder has been designed based on 51 SCM, and the button switch and the microcontroller I/O are used as the input and output, the digital tube and the I/O are used as display function. The software is programmed with C language, which is simple and easy to understand and very intuitive, at the same time, the whole design is simple and practical. After testing, the system can realize the eight channel responder function and can be conveniently applied to the game.
