Fast forward to January 23rd We have Early Access launch which is awesome! As later people digging through the gamefiles it come clear that the game use Unreal Engine 5.\nThought because I liked this series far way back in PS2 era, I decided to maybe give back small contribution to the community by making custom GUI app for save editing the game.\nYou can check my repo for the app itself\nrafliard23/txr-use-py GUI-based save file editor for Tokyo Xtreme Racer 2025 Python 18 1 It\u0026rsquo;s a wrapper app # Tokyo Xtreme Racer Save Editor app layer overview First roadblock that came to me was Serial-Deserialize the save file. Unreal game are saved in a way that\u0026rsquo;s packed by specific function. The save file structure are clear enough that you can edit it with hex editor however we would encounter byte collision if we add or remove additional bytes into the file, thus we would move in ready-to-use tool to save time not to mention this is my first UE5 game that I play! (well I don\u0026rsquo;t want to spend time writing Ser-Des function myself).\nThere goes I found this fancy cli tool that enough for my use case. Serial and Deserialize the UE save file (.sav) into JSON document (.json) and vice versa.\ntrumank/uesave Rust library and CLI to read and write Unreal Engine save files Rust 422 69 By any means the cli tool alone is the save editor itself, however to make things easier for user we can add additional front end to edit what user want and convert it from the value into respective block of data that need to be edited then save it as .sav file once player hit \u0026ldquo;Save\u0026rdquo; or \u0026ldquo;Save As\u0026rdquo;\nHow it works # Loading File Process # Loading save file deserialize into .json file First and foremost the Editor UI needs you to load a save file .sav which we will save the path for processing later on. This path will be piped to uesave-cli which converts the .sav into .json onto specified folder we set.\nEditing Data # Open loop data editing overview Once we have our .json save file, we can edit it right away and adjust any value according to valid range and reasonable set. Almost any value related to player character can be edited that affect achievements however for in-game freeroam related check they may checked over raceinfo entry that loaded in transient or volatile in memory during gameplay. This save editor front end at best very basic as I don\u0026rsquo;t want to expand the GUI to attribute larger customization (e.g plate modding, muffler swap and some tricky edits). Once we complete edit the value, we can write our changes into the .json file.\nPut it back as .sav # Saving .json file into save file This process handled by uesave-cli with help of GUI to retrieve our original path of .sav file and as conversion output path of uesave-cli.\nRemark # I believe the next logical step would be implement this editor as in-game Trainer to make things more streamlined and contained within the game. Although I have not start the process as a lot of things to do in real life, maybe somebody would make it before I complete it myself, who knows. All that matters is that I want to make something and share it in case someone find it useful though I find it limitating :p\n","date":"Monday, 12 May 2025, 17:29","externalUrl":null,"permalink":"/projects/txrsaveeditor/","section":"Projects","summary":"Simple GUI Save Editor for Tokyo Xtreme Racer (2025) using uesave-cli and Python","title":"Tokyo Xtreme Racer - Save Editor GUI","type":"projects"},{"content":" Tumpukan buku dengan ajakan untuk membaca. Sumber:Paul Cross dengan lisensi CCA-2.0 Generic Membaca manual book, datasheet, ataupun petunjuk merupakan hal biasa bagi segelintir orang, namun efeknya begitu besar jika dibiasakan terutama bagi kita yang dari latar belakang engineer, teknik, atau akademisi. Mengetahui petunjuk pengunaan alat atau mengidentifikasi komponen yang kita gunakan adalah separuh tanggungan yang perlu kita penuhi agar pekerjaan yang kita lakukan bisa beres, sisanya adalah usaha yang kita lakukan dalam mencapai target atau tujuan penggunaan alat/komponen yang kita pilih\u0026hellip;\n(Pembiasaan) Membaca Petunjuk untuk Mencapai Tujuan # Datasheet MOSFET IRFZ44N Membaca manual book, buku petunjuk, dokumentasi project merupakan hal esensial bagi developer atau engineer ketika menghadapai hal yang asing. Membaca adalah salah satu metode untuk menggali informasi yang universal tanpa memandang bidang. Secara harfiah, membaca sendiri bisa bermakna \u0026ldquo;menangkap\u0026rdquo; informasi dengan menggunakan indra manusia yang menghasilkan ide, analisa, pertimbangan, dan pemecahan masalah terhadap konflik atau problem saat itu. Membaca mampu memangkas waktu kita dalam proses transfer knowledge karena kita tidak perlu orang lain untuk menangkap informasi yang disodorkan atau dibutuhkan.\nPembiasaan membaca manual book sangat krusial sebagai developer atau engineer, semakin terbiasa kita membaca datasheet semakin mudah kita mendapatkan informasi yang kita inginkan dengan waktu yang lebih efisien. Selain itu dengan terbiasa membaca datasheet, kita juga menjadi lebih self-service dan tidak bergantung kepada orang lain untuk belajar hal yang banyak dijumpai (umum). Keterbiasaan membaca juga mendorong seseorang untuk lebih kritis, paham, dan terbiasa untuk mencari informasi secara mandiri.\nEsensi Membaca Petunjuk # Esensi membaca petunjuk mendorong seseorang lebih mandiri dan manfaat yang tak ternilai, beberapa poin seperti:\nKemandirian # Dalam KBBI, mandiri /man·di·ri/ a dalam keadaan dapat berdiri sendiri; tidak bergantung pada orang lain. dan kemandirian /ke·man·di·ri·an/ n hal atau keadaan dapat berdiri sendiri tanpa bergantung pada orang lain.\nDari definisi di atas, kemandirian dalam konteks kemampuan (atau dalam profesi) merujuk kepada kemampuan kita untuk berdiri sendiri dalam menghadapi problem, konflik, isu maupun tantangan. Kemandirian mendukung agar kita berkembang dengan kemajuan teknologi dan menjamin kita terhadap informasi terbaru tanpa perlu menunggu orang lain.\nPemahaman tinggi # Dengan membaca buku petunjuk, manual, dokumentasi tidak serta-merta bisa langsung menjawab isu atau problem yang kita hadapi, tetapi dengan membaca kita memahami bagaimana suatu proses berjalan atau cara kerja suatu sistem beserta perangkat-perangkat kecil di dalamnya. Semakin kita memahami sesuatu secara mendalam, semakin mudah dalam melangkah untuk menyelesaikan problem.\nPembiasaan mencari tahu (riset) # Kini arus informasi sangat pesat beredar bahkan semakin mudah untuk kita mencari sumber informasi dengan mudah untuk memverifikasi sesuatu yang ingin kita cari. Misalkan kita membeli komponen transistor tetapi kita ragu dengan barang yang datang ketika sampai di rumah, kita bisa memverifikasi transistor ini dengan mencari informasi langsung dari datasheet pabrikan transistor.\nMelakukan riset (pertimbangan) juga hal yang wajib sebelum mengambil keputusan (baik dalam desain atau melakukan sesuatu) semakin banyak informasi yang masuk semakin mudah kita memutuskan dengan input informasi yang ada. Melakukan riset juga mengembangkan kemampuan berpikir untuk mengidentifikasi masalah, dengan mengenali masalah yang dihadapi kita mampu menyusun langkah-langkah yang perlu dilakukan untuk mencapai solusi.\nPemecahan masalah # Menyelesaikan masalah dengan mengikuti buku panduan, manual, dokumentasi membuat kita semakin mudah untuk mengenali masalah yang dihadapi, hal tersebut relevan dengan pengalaman yang kita miliki. buku panduan, manual, dokumentasi ini merupakan informasi yang sangat membantu dalam mengidentifikasi masalah. Dari membaca ini lah membuat kita semakin terbiasa dalam mendiagnosa masalah, mencari solusi, dan memutuskan metode mana yang paling tepat.\n","date":"Thursday, 19 December 2024, 18:50","externalUrl":null,"permalink":"/id/posts/2024/12/rtfm/","section":"Posts","summary":"Membaca manual book, datasheet, ataupun petunjuk merupakan hal biasa bagi segelintir orang, namun efeknya begitu besar jika dibiasakan terutama bagi kita yang dari latar belakang engineer, teknik, atau akademisi.

Mechatronics 2019 Politeknik Elektronika Negeri Surabaya. Untuk saat ini saya sangat berminat untuk lanjut mempelajari bidang Elektronika, Embedded Hardware dan Software, serta bidang desain Gambar Mesin.\nSaya sangat bersyukur terhadap pilihan saya dalam mengenyam pendidikan vokasi pasca lulus SMA. Keputusan saya untuk memilih Sarjana Terapan Teknik Mekatronika ini tidak lain karena saya ingin berubah, ingin menjadi seseorang yang lebih bermanfaat kepada orang lain serta masyarakat sekitar. Menurut saya Mekatronika adalah salah satu cabang ilmu yang praktis dan pasti digunakan, baik secara sehari-hari maupun spesifik seperti bidang industri. Dari hasil yang telah saya jalani sebagai Mahasiswa Mekatronika, saya merasa sejauh ini saya telah merasakan manfaatnya baik secara diri sendiri, keluarga, bahkan sekitar rumah.\nPada awalnya ketika saya beranjak dari lulus SMA menuju jenjang Perguruan Tinggi, saya dihadapkan dengan dua pilihan waktu itu, yakni masuk Vokasi dengan Teknik Mekatronika (yang saya anggap setara atau lebih dari Teknik Mesin pada saat itu), atau memilih studi Srata-1 Teknik Kimia disalah satu perguruan tinggi negeri di Surabaya. Karena niatan saya waktu itu ingin masuk ke program Strata-1 di salah satu perguruan tinggi negeri terkemuka di Surabaya, akhirnya saya lebih memilih ke Teknik Mekatronika terutama dalam benak pikiran saya adalah \u0026ldquo;Robotik/Mekanika+Elektronika adalah masa depan!\u0026rdquo; (Tentunya hal ini benar namun di Indonesia masih pada skala Industri). Pada waktu itu ketika masa transisi lulus SMA hingga beranjak tahun pertama saya kuliah saya terkadang memiliki pikiran \u0026ldquo;Apakah benar ini adalah pilihan yang terbaik bagi saya?\u0026rdquo; Tentunya skeptis atau keraguan adalah hal yang normal terlebih bagi saya sebagai lulusan SMA yang dari awalnya tidak mengenal Perteknikan (Engineering). Patut bersyukur, saya melewati tahun pertama dengan lancar serta mencari kesibukan yang lebih berarti untuk menyalurkan hasil yang telah saya pelajari ke dalam dunia riil.\nAntusias untuk mempelajari ilmu baru, dan tertarik terhadap Hardware, Embedded, dan Elektronika.\nBerawal dari lulusan SMA tidak membuat saya merasa kurang ketika menginjak pendidikan lanjut D4 Teknik Mekatronik, tapi hal tersebut kemudian membuka saya bahwa Keilmuan ini sangatlah luas dan bagi yang haus ilmu pasti akan bersyukur terhadap luasnya ilmu yang dapat digali. Hanya kemauan yang menjadi batas seorang pelajar/manusia untuk menggali potensi dirinya sendiri.\n","date":"Monday, 14 August 2023, 00:12","externalUrl":null,"permalink":"/about_long/","section":"","summary":"Situs ini merupakan salah satu perwujudan fasilitas penuangan ide yang saya miliki.

Karena penggunaan program kendali proses CNC yang digunakan masih menggunakan Mach3, maka kami memerlukan untuk mencari komputer dengan port Paralel agar mesin CNC bisa dikendalikan langsung oleh komputer. Penggunaan komputer dengan port Paralel ini sangat penting karena kemampuan untuk Torch Height Control (THC) hanya dapat digunakan pada board dengan port Paralel, board CNC Mach3 yang menggunakan interface USB tidak dapat menggunakan fitur ini karena pada program kontroler bawaan board CNC Mach3 USB tidak diimplementasikan untuk Plasma cutting, hanya mampu untuk digunakan sebagai CNC Milling/Laser Cutting.\nTampilan interface program Mach3. Setelah selesai penyetelan kalibrasi motor stepper+driver terhadap program Mach3, kemudian dilakukan penyetelan Torch Height Control (THC) dengan membuat kontroler THC sendiri (berbasis Voltage divider dan ADC op-amp). Pembuatan kontrol THC ini menggunakan prinsip kondisi tegangan dari Torch ketika Torch menyala, Torch akan memiliki nilai tegangan threshold ketika tegangan ini melibihi ambang batas, maka Torch akan menempel pada pelat ketika proses pemotongan sheet metal, hal ini terjadi karena nilai tegangan tersebut dihasilkan dari beda potensial tegangan yang terjadi antara ujung Torch dengan sheet metal yang akan dipotong, sehingga perbedaan tegangan ini dapat digunakan sebagai referensi untuk kontrol ketinggian Torch ketika proses cutting sheet metal.\nBerikut ini adalah demo dari mesin yang telah dikalibrasi dengan mencoba profil cutting sederhana\n","date":"Wednesday, 16 February 2022, 11:59","externalUrl":null,"permalink":"/id/projects/cncplasma/","section":"Projects","summary":"Proyek ini merupakan salah satu proyek Kerja Praktik saya di CV.

It was UAV research to develop a Tri motor Hybrid UAV in detail with two of three motors capable tilting vertically and one motor fixed in vertical position, as result the UAV capable to take off and landing Vertically. The name of the developed prototype product is “EEPIS Versatile Cargo Aeroplane” (EVARO). This research development acts as internal research and entry for the National Aeronautical Robot Competition (Kontes Robot Terbang Indonesia abbreviated as KRTI) for the year 2021.\nAs a team, we are Dirgantara PENS team under EEPIS Flying Robot for Indonesia (EFRISA) flag, EFRISA compete in Techno Development category with sub team that each participates on each sub division competition. In Airframe Innovation sub team, we are five-person team with three being handler for several tasks and two person as a crew helping to complete the tasks. In this team, I am handled electrics and hardwares of UAV, for some occasion I also help mechanical maintenance and manufacture.\nOverview # Assembled UAV and its Packaging EEPIS Versatile Cargo Aeroplane (EVARO) is UAV that developed with logistic background. This UAV submission in the National Aeronautical Robot Competition 2021 on Techno Development category with Airframe Innovation sub division. In this category, scoring was determined by development that conducted on developed UAV for each entrant, for this sub division airplane configuration, system, and airframe component are the main inspected parts for scoring.\nBlueprint of EVARO UAV Specification detail of UAV EVARO:\nConfiguration: Skyhunter Hybrid Tilt Rotor Hybrid Classification: Hybrid VTOL Tail: V-Tail Propulsion: 3 Motor; 2 Motor Hybrid, dan 1 Fixed Vertical Wingspan: 1400mm Length: 970mm Maximum Take off Weight (MTOW): 3200g Maximum payload Weight: 500g Material: Composite and PET Electrics Hardwares # Aside of usual UAV electrical hardwares, this development add a \u0026ldquo;Tilt rotor\u0026rdquo; which mount a motor into a servo motor arm so the motor orientation can be controlled in order to achieve hybrid configuration (Fixed Wing Aircraft and VTOL plane). During VTOL stage, all three motors used to propel the UAV into higher altitude, and as the UAV achieve enough altitude to transition into Cruise mode (Fixed Wing aircraft), the tilt rotor will rotates from facing upward to face forward to act as twin motor UAV with the fixed vertical motor shutdown during Cruise mode to save more energy during flight. Compared to Quad Plane configuration, this configuration save better energy as the motor count lower and most of flight going to have maximum of two motor turned on.\nUtilization of Servo motor for Tilt rotor To achieve this hybrid configuration, we use Gearboxed Servo in order to control motor during flight. We have tested 15kg gearbox is enough but for competition and research, we opted to use 35kg for safety factor. Tilt rotors mounted on each servo motor arm with motor heading facing same orientation as servo arm.\nTilt Rotor Servo Drive # Servo motor for tilting the motor With the way tilt steering works, the servo motor also controls the yaw movement during VTOL phase, the servos react accordingly based on gyroscope input and then balances the UAV. The servos during VTOL phase has angle travel limits for its up facing orientation with 15° limit tilting forward. During Cruise mode, the servos hold on the 0° angle to ensure maximum forward force. The mode selection controlled by Ground Control Station or if UAV is within Remote radius, can be switched using Remote Switch (according to assigned channels on Remote PPM/Transceiver).\nHere\u0026rsquo;s our publication as poster which is mandatory as part of Competition submission.\nResearch Poster for KRTI 2021 TDA ","date":"Friday, 31 December 2021, 21:57","externalUrl":null,"permalink":"/projects/evaro/","section":"Projects","summary":"1st place awardee for Airframe Innovation - Techno Development in National Aeronautical Robot Competition (Kontes Robot Terbang Indonesia; KRTI) 2021. 3-motor Tilt rotor hybrid VTOL.","title":"EEPIS Versatile Cargo Aeroplane","type":"projects"},{"content":"","date":"Friday, 31 December 2021, 21:57","externalUrl":null,"permalink":"/tags/hardware/","section":"Tags","summary":"","title":"Hardware","type":"tags"},{"content":"","date":"Sunday, 12 December 2021, 09:52","externalUrl":null,"permalink":"/tags/embedded-system/","section":"Tags","summary":"","title":"Embedded System","type":"tags"},{"content":"","externalUrl":null,"permalink":"/authors/","section":"Authors","summary":"","title":"Authors","type":"authors"},{"content":"","externalUrl":null,"permalink":"/series/","section":"Series","summary":"","title":"Series","type":"series"}]
