VXmaus!build a mini arcade in VEWLIX style【LABODOJO】001


la~la~lalala Welcome to Labodojo! The arcade industry was once very hot in the 1980s-90s Into the 21st century, changes have taken place in all aspects of the market One of the major innovations in hardware technology LCD Replaces CRT devices So a batch of new specifications of the LCD cabinets ware designed and manufactured Vewlix of Taito is among them Vewlix’s outstanding industrial design Has made itself the most popular universal LCD cabinet Many of the large game halls that are still in operation are based on his main model. Businesses are well maintained and manufacturers are constantly updating Players also enjoy his look and control Even those who are so full of true love that they must carry home If this is not enough Then come with me Build a mini version of Vewlix– VXmaus! Design must first clarify core principles Is desktop while maintaining the visual characteristics of VEWLIX The most important points are: 1, the fuselage, the console, the side of the straight line and mutual angle. 2. Edge geometry and mechanical sense. 3.A four-corner layout speaker that can rotate the screen module vertically. To put it simply, desktopization is to maintain the relative angle and proportion of each component Then zoom out So the first thing is to determine a critical dimension The overall structure is adjusted proportionally This question can refer to the development of home fighting stick and the market experience of hori for many years Since the early 1990s, Street Fighter 2 has caused a wave of fighting Transplanted to console MD, SFC, PCE at the time 3 rd party manufacturers began to manufacture various supporting fighting sticks Most of them feel bad One of the important reasons is that the size is not suitable Thus the overall cramp, affecting the sense of control Until Hori discovered that he wanted to find the optimal solution in the field of metaphysics of manipulation Reliable reference only empirical data In 2004, Hori’s RAP (Real Arcade Pro) was born. Use arcade console layouts and accessories directly Keep enough hand space and palm rest size The overall weight and stability also keep up Greatly improved operation comfort The origin that changes everything is the ideal width dimension 40 cm! This data is actually the result of ergonomic statistics Until now, every generation of hori products Are clearly divided into three product files according to the width The first, the mainstream model: about 40 cm wide, Such as RAP1,2,3: 41 cm RAP4,5: 43 cm For the same reason, several other well-known competitors have similar sizes. Madcat te2: 38 cm Razer: 40 cm; Second, luxury models: increase the hanholder on both sides For example, the blade series: 48 Third, small Sacrifice maneuverability to reduce costs for less hardcore players Such as mini series, 21 cm This gadget is new and okay, but not suit for longtime play. the more smaller kind ,I’m afraid it’s just a matter of love, let alone In addition to determining the right width, there are several requirements for miniaturization and home use 1.Maintain the sense of operation of the large frame level
2. Minimize the size without affecting the stability
3, a complete matx computer can be installed inside
4.Removable machine and rotating screen can be done quickly
5. Cost-effective processing In the first round of design, draw a sketch according to the upper half of the original machine.

4.Removable machine and rotating screen can be done quickly
5. Cost-effective processing In the first round of design, draw a sketch according to the upper half of the original machine. Reduce the console with a width of 40 cm Dimensional requirements for other devices can be calculated Such as power, connectors, LCD, speakers, etc. Synthesize more hardware requirements and find specific device models The obtained final model parameters are fed back to the sketch design for optimization On the basis of the second round of design, the details of the shape are added Including, tilting screen, trapezoidal convex edge, rounded transition frame, sharp angle rocker side, etc. These details and specific data are referenced by actual machine mapping And in terms of structure, we must consider the feasibility of installing and processing various spare parts. In the end, the design result is 40 length, 38 width, 47 height The LCD screen used is 14 inches, 16 to 9, and the round speakers are 3 inches. After the design is completed, the processing chart and bom table are output, and the inventory is sorted. Mainly divided into three types of processing technology Main structure parts use 1-2mm steel sheet metal Because all are complex angles, be sure to use precision CNC sheet metal After the sheet metal part is completed, first carry out a trial assembly Try to install ok and then pickling and spraying Flat panel is cut with acrylic laser, outsourced Shaped parts, side and top frame After the tradeoff, use 3D printing In addition, there are some decorative paper products, although you can print and cut directly But there are a lot of holes on the top. If you dig all the holes by hand, it is troublesome. The normal machining method requires a high-power laser It’s too wasteful to use bull knife to kill chicken Later I tried to use the CNC machine to cut the edges directly As long as the depth is controlled, the effect is still good Now start assembly The first is the back frame Supported by two 3mm thick ribs Click on the upper and lower locks and then weld, so that the structural strength of the back frame itself is guaranteed I have installed two 12 cm fans here. Note that there are two pairs of mounting holes under the side ribs, which will come in handy later Install an acrylic base plate on the inside, this is used to install the built-in PC On the left is the 2.5-inch hard disk installation location The copper pillars are arranged on the bottom plate according to the matx hole specification. Tighten the acrylic base plate and back frame with screws This part is done The installation of the console is the same as the ordinary DIY joystick Console floor, acrylic panel, liner paper Can be replaced according to your favorite button layout Install buttons and joysticks one by one Tighten the panel screws The joystick chip here is xbox360 In addition to the xbox360, the PC and embedded simulator support is also very good. Of course, you can also change the chip of other models Function buttons use 16mm buttons Connect the button and joystick wires Cable tie finishing line Close the joystick panel OK, the console module is assembled LCD modules, all integrated into this square box Four 3-inch round speakers have been installed here Turn it over. For the convenience of wiring, the speaker wires are welded into two groups LCD screen is Samsung 14-inch, resolution 1366-768, 5ms response LCD stand made of acrylic The back is the LCD driver board, Lehua amplifier integrated Comes with vga, hdmi interface, lotus and 3.5 inch audio The choice of screen and speakers largely determines the look and feel of the whole machine Is important at the beginning of design After estimating the size of the screen from the width of the whole machine Find models with suitable parameters in Panelook Screening of several of their key parameters Then go to the market to find the supply source according to this model Find the corresponding technical documents at the same time Because there are detailed installation dimensions and communication methods on it This information will also be used to adjust other related components. Fix these parts Make a set of audio cables and connect the speakers to the amplifier The infrared remote control connector of the driver board is installed in a remote place Also make an infrared extension cable in advance. After everything is installed, the entire module can also be used as a single small display The interface port for external LCD is also made into a module Includes a set of Lotus, 3.5-inch audio, HDMI, VGA, two sets of USB, and power and switch All interfaces are female to female two-sided plugs Ability to switch between internal and external hosts It’s time to complete the assembly Console bottom plate also has a pair of 3mm thick ribs 2 sets of bolts on each side are connected to the bottom plate of the back frame Tighten the holes on the side and the ribs of the back frame The cross combination of these two sets of ribs is the strength of the entire machine. Someone may ask here, why not just make a full page and separate it? I will give the answer at the end of the video. Maybe you already think of it. There are two openings on the back frame for installing expansion interface panels This one on the left is not needed for the time being, so plug it directly with a square plate Install the LCD interface port module on the right The internal power supply is a matx power supply, 200w power Enough to drive LCD and general embedded small hosts Due to power consumption and heat dissipation issues, it is not recommended for more than 300w Therefore, if a built-in PC is installed, the hardware configuration is also limited by this. Left side frame and joystick left The original machine is a plastic part and requires an injection mold Of course this cost is too high for DIY, There are several alternative processing options: 1. Wood CNC, high material requirements, complicated pre- and post-treatment processes, and poor durability. 2. Aluminum alloy CNC, simple processing, high comprehensive cost, and significant increase in weight. 3, PLA 3d printing, the top frame size needs to be split, and complex structures can be simplified. After the comparison I used 3D printing. This is the side of the console previously made with wood CNC Because the weather is too hot, the topcoat is gelled and has already broken Before installing the top frame, thread the prepared LCD infrared receiver from below. And fixed to the top frame Lightbox poster inserted into the slot of the top frame Connect the LCD module to the interface port The LCD module frame snaps into the groove of the back frame rib After everything is installed, pick up the two side frames and snap to the LCD panel The LCD panel is the same as the control panel.can be locked by ribs So it won’t loose even without screws, which is convenient for installation and testing Everything is OK, then use the upper and lower blanks to lock the LCD module. Take a look, the most comfortable thing for structural engineers is to install the prototype tightly. Finally, tighten the 8 screws on the side frame from the back You’re done Since it is equipped with an Xbox360 joystick chip Here’s a test with an Xbox360 Use USB and HDMI dual male cable to connect small arcade and 360 respectively Remote LCD vedio-in channel to hdmi Connect with another laptop and run Steam Street Fighter 4 Compare the design drawings Similarity is 100%! When I test the shaker, I will look at simple combos and 720 If these two are okay, the whole set is ok Change to steam Ikaruga Ikaruga, of course, need to experience in vertical mode Way to switch vertical screen,Go behind Remove the side frame with 4 screws on each side Turn back positive Remove the upper and lower blanks of the screen module, 3 screws each Incidentally, if only maintenance of the joystick Only need to remove the 3 screws of the blank Remove the side frame, it is relatively tight, it is more convenient to use a wrench Remove the LCD module from the bezel Rotate 90 degrees be careful not to twist the internal wires Put it back in reverse order Boot up and run the game Compare it with the design Guessed it? The lower body of the small arcade can be removed and used as an independent cradle. Alright, that’s it for this episode
