Design of Automatic Candy Mixer using Blynk and NodeMCU ESP8266
No full textCandy has many variations based on shape, texture, and taste. The more variations of the product have an effect on more consumers, Candy products also have a lot of
variety, which makes mixing candy an interesting task. The mixing process of candies is usually done by weighting them manually with conventional scales, so there are some
deficiencies to be improved. The automatic candy mixer using Blynk and NodeMCU ESP8266 has been designed to be able to help with the process of mixing and weighting candy
automatically. This device allows users to choose weight and candy types to be mixed, whether it is one type of candy or more, from the Blynk application and is operated using a
microcontroller and sensor. The utilized sensor is a load cell sensor with 1% of calibration inaccuracy

Get PDFAntena array adalah suatu antena yang dibentuk oleh susunan sejumlah elemen antena tunggal yang biasanya berupa antena dipol dimana setiap elemen tersebut diberi arus. Antena ini merupakan cikal bakal pengembangan sistem antena cerdas. Salah satu kelebihan antena array adalah dapat menghasilkan variasi arah lobe radiasi utama dengan mengatur beda fasa pengumpanan arus tiap elemennya. Antena array berikut ini dirancang dengan menggunakan 4 elemen antena dipol tunggal pada frekuensi operasi 2 GHz dan memiliki penguatan antena 3.39 dBd. Beda fasa pengumpanan arus diatur secara manual melalui beda panjang saluran transmisi antara tiap elemen array. Melalui pengujian dengan menggunakan generator sinyal dan spektrum analyzer, diperoleh daya radiasi yang kemudian digambarkan dalam bentuk pola radiasi. Berdasarkan pola radiasi tersebut terlihat adanya variasi arah lobe radiasi utama dengan 4 beda fasa pengumpanan arus yang berbeda dan hasil ini telah memenuhi spesifikasi dan mencapai tujuan dari perancangan
Establishment of an application for photographs’ quality detection based on sharpness and light intensity
No full textAlong with the booming of digital photography, camera users grow significantly,
especially the users of digital single-lens reflex (DSLR) camera. There are many new users who
apply their DSLR cameras for the first time and have little knowledge how to use them. That’s
why an application is needed to guide a novice user so that he/she could get better understanding
about photography. We have an idea to create such a guidance application that can provide
evaluation and suggestion about the quality of user’s photographs. Thus, users can easily
develop the ability of photography. Overall, the level of accuracy of this application in
identifying deficiencies in the pictures taken is about 75%. This level of accuracy is calculated
from errors that occur in detecting both sharpness of the pictures and light intensity (exposure)
of the pictures, or any one of them. The errors in detecting the conditions of pictures, occur in
some pictures. Hence, it needs further development of methods to improve the accuracy in all
conditions of pictures taken. Best accuracy is necessary so that the pr
IMPLEMENTATION OF 3D HRTF INTERPOLATION IN SYNTHESIZING VIRTUAL 3D MOVING SOUND
No full text3D sound is a new trend in various media, such as movies, video games, and musicals.
Interpolated head-related transfer functions (HRTFs) are a key factor in its production, due to
real-time system limitations in storing measured HRTFs. In addition, the interpolation of
HRTFs can reduce the need to measure a large amount of HRTFs and the associated effort. In
this research, we used the PKU-IOA HRTF Database and covered three interpolation
techniques, namely bilinear rectangular, bilinear triangular, and tetrahedral. Bilinear
interpolations can be used to compute weights in interpolating measured HRTFs in a linear
fashion, with respect to azimuth and elevation angles. Such interpolations have been proposed
for three measurement points that form a triangle or for four measurement points that form a
rectangle, surrounding the HRTF at a desired point. These geometrical approaches compute
weights from a distance of the desired point from each measurement point. Tetrahedral
interpolation, meanwhile, is a technique for HRTF measurements in 3D (i.e. azimuth, elevation,
and distance) using barycentric weights. Based on our experiments, 3D tetrahedral interpolation
results in the best average mean square error (MSE) of 3.72% for minimum phase head related
impulse responses (HRIRs) and best average spectral distortion (SD) of 2.79 dB for magnitude
HRTFs, compared to 2D bilinear interpolations (i.e. rectangular and triangular interpolation).
Regarding the latter, bilinear rectangular interpolation generally performs better than the
triangular variety. Additionally, the use of minimum phase HRIRs as input data results in more
optimal interpolated data than magnitude HRTFs. We therefore propose an optimal framework
for obtaining estimated HRIRs by interpolating minimum phase HRIRs using tetrahedral
interpolation. Such HRIRs have been simulated to produce virtual 3D moving sound in a
horizontal plane with a difference of 2.5
