[Color Silkscreen Printing] Genshin Impact Transformation Device [Voice Playback]

The Genshin Impact transformation device
is now complete . The design is inspired by the Kamen Rider transformation device and incorporates its features. The pattern is from the official badge stickers released by miHoYo; other patterns can be used as needed. It uses the reprogrammable chip WT588D-20SS, which is readily available and easy to use (but has been discontinued due to its age and inability to be driven after downloading). A nine-core NV400F chip has been replaced. Single-piece and four-piece prototypes were created within the project. The four-piece prototype requires manual cutting but is more cost-effective. Printing is optional. The board features a pure bottom-layer layout with no vias. To ensure a complete top surface soldering, the positioning posts for the Type-C port, switch, and buttons need to be cut off. The images below are from the old version; the new PCB has been redrawn. Operation: Pressing the top button produces a sound effect. The board is only designed for single-button operation, but multi-button operation and programming are possible; modifications can be made if needed. The burning tutorial and software file are too large to upload. They have been uploaded to Baidu Cloud via this link: https://pan.baidu.com/s/17g81MBAu6D0OjQcWWzcYtQ?pwd=td40 Extraction code: td40. The official TTL burning tutorial verification failed; an offline dongle is used for burning. The dongle needs to be purchased separately. [Offline Dongle Copying] The audio conversion software in the package converts MP3 audio to FLA format. Import all audio files and command txt files into the offline dongle. The key command is "down". The format must start from 000, otherwise it will not be recognized . Due to space limitations on the PCB , various coil types were tested. A single coil can be recognized, but after adding a battery, the coil cannot be recognized because the battery shields the operation. Neither of the two PCBs in the project could be used, so a self-made coil was finally used. The phone can recognize the device after adding a battery in the project. The outer shell is made of 3D transparent 8001 stainless steel. The version shown in the project is without chamfering and logo. The STL file in the link has been refined; you can choose to print it yourself. Fasteners: 3 M2 screws , 6 M2 knurled nuts (just align them). Battery: C5182591 , size 402030. You can purchase this yourself. For the project, you can choose a smaller battery from LCSC. Speaker: C530539 GSPK151035PN-8R0.5W-L35-1.25T chip, can directly drive an 8R0.5W speaker. You can purchase this yourself. Other power ratings like 1W and 0.7W can also be driven. Video: https://www.bilibili.com/video/BV18N411u7Hr/?spm_id_from=333.999.0.0
