It's written in C++20 with Vulkan rendering, and currently combines imported game assets with racing physics, weapons, multiplayer and replay tools.\n\nThe longer-term idea is a motion simulator pod, with acceleration, braking, cornering and impacts driving physical movement. Positional audio and multiple displays are part of that plan. My [Car-cade](https://projectable.me/my-dirt-rally-tabletop-car-cade-game/) and [motion rig](https://projectable.me/sim-racing-motion-rig-v2-updates/) explored the hardware side of racing; this time I'm working on the engine that would feed it.\n\nDevelopment started in January 2026 with AI-assisted planning and implementation. I've used coding agents throughout, with a large part of the work going into the references, constraints and tools they need to make changes that can actually be inspected and tested.\n\n![Original NullG ship artwork](/content/images/2026/10/583bdbe059a6-ship.png)\n\n## Getting started\n\nThe first git commit was on January 22. It contained the outline, research files, architecture notes and initial application code: a window, Vulkan setup, input, configuration and logging. The plans already included asset conversion, audio, networking, computer-controlled opponents and motion output.\n\nI put the race simulation at the center of the design. Graphics and sound consume its state, and the eventual motion hardware would read from the same data. That kept the simulator idea part of the engine rather than something to bolt on after the rendering worked.\n\nEarly development used Cursor, with commands for planning, preparation and review. Preparation meant reading the relevant references and tracing the code before making changes. Smaller tasks, examples and written decisions gave the next session something useful to start from.\n\n![Early NullG team-selection screen with FEISAR selected](/content/images/2026/10/037075fac8ed-G_jZiq3WQAAg2Cz.jpeg)\n\nAsset conversion and the first renderer pass arrived on January 23. Menus, model loading, asset management and track parsing followed over the next few days. Existing WipEout research and community projects supplied references for the ships, tracks, textures and scenery.\n\nBy February 8, NullG could load PlayStation assets directly. That work covered track geometry, scene objects, sprites and texture transparency. With those pieces in the renderer, the imported data could finally be compared with what appeared on screen. The file-format notes and agent rules grew alongside the loaders.\n\n## Getting a race working\n\nMarch was more about how the ship moved: hover height, coasting, weight, jumps, boost, recovery and tunnel-wall collisions. There was also work on scenery placement, skies, pickups, boost pads and the track camera behind the menus.\n\nLighting, shadows and GPU particles were added to the presentation. By March 6, the code included race-session flow and a weapon system, including getting into a race and back to the menus. The changes were handled as individual tasks with code review and updated notes, rather than expecting one session to keep the whole engine in context.\n\nIn May I split the original engine plan into focused documents with a shared status index. Renderer work covered dynamic rendering, geometry access, material organization and moving runtime shaders to Slang. Animated scene lights, illuminated pickups, shields and scenery shadows on ships received attention too.\n\nAn entity/component scene system and render snapshots were added during that period. A render snapshot holds the data needed for a frame, including ship and object positions, so the renderer has a consistent state to draw.\n\nBy May 28 there were headless tests for the job system, memory and asset handling. Agents could run them after an edit and read the results. The inspection tools grew from there.\n\nJune brought Jolt collision integration and more GPU effects work. Research notes on effects, shadows and physics kept established examples available for implementation tasks. On June 9, XL became the default asset source. Each source supplied the information the menus needed to show its available choices. Waterfall texture scrolling and the starting-grid camera were among the other changes.\n\nThe next concentrated stretch started on October 9, bringing the agent guidance into Codex, adding native engine inspectors and establishing the fixed 60 Hz race setup. Multiplayer followed on October 10, with more XL reconstruction work on October 11.\n\n## Letting the agent inspect the result\n\nIn October I switched NullG's coding-agent work exclusively to OpenAI Codex. The planning commands, rules and research notes came across from Cursor. The next step was giving Codex access to the engine tools it needed to check its own work.\n\nI'd recently watched videos about Blender MCP showing an agent working directly with a scene and inspecting the result. That helped shape both the model-authoring process and the decision to connect agents to NullG's native tools.\n\n[MCP, the Model Context Protocol](https://modelcontextprotocol.io/introduction), connects AI applications to external tools and data. In NullG it exposes inspection windows, track validators, model viewers and controlled race sessions. The agent can load a track, pick a camera, inspect geometry and save a frame. For a model, it can look at materials, bounds and different angles.\n\n![NullG Track Validator showing track geometry, texture inspection, and timeline controls](/content/images/2026/10/nullg/intro-track-inspection.png)\n\nThe weapon harness opens a paused production race. It lets the agent deploy a weapon and advance a few frames at a time, then inspect a projectile, impact or Quake effect at a particular moment. The simulation state is available beside the picture.\n\n\u003ciframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/pbUzB3j74p8\" frameborder=\"0\" allowfullscreen\u003e\u003c/iframe\u003e\n\n*Reactive engine plumes in the MCP harness.*\n\nFor a weapon-effect fix, the process is to set up the scene, fire the weapon, step through it and follow the responsible code. After an edit, the agent builds the affected code and repeats the same case. Reports keep the inputs and settings so another session can reproduce it.\n\nThe different checks answer different questions. Physics tests compare movement with expected values; track checks look at road geometry. Replaying the same inputs helps find changes in behaviour. I still need to review appearance and handling, but the agent can do more of the setup and leave the reports and captures for me to inspect.\n\n![Ships racing with engine trails and a weapon effect in NullG](/content/images/2026/10/nullg/nullg-ships-weapon-action.png)\n\n![Diagram showing an agent connected through MCP to native inspection and headless validation tools](/content/images/2026/10/nullg/intro-agent-workflow.png)\n\n## Reconstructing XL behavior\n\nOctober's research went further into WipEout XL / 2097 steering, weapon updates, starting positions and animated objects.\n\n[REA, Reverse Engineer Anything](https://github.com/morluto/rea), was part of that setup, connecting agents to tools for investigating applications and binaries. The PlayStation executable decompilation used a PSX-aware Ghidra workflow. Scripts saved the instructions, references, annotations and findings so the investigation could be picked up again.\n\nStarting-grid placement is a useful example. Following the original track numbering and route links established where the ships should start. Those findings became checks against the imported track, and the inspector could show the selected position on the road.\n\n![An overhead track inspection with a highlighted grid marker](/content/images/2026/10/nullg/intro-grid-placement.png)\n\nThe research covers USA and European editions, retaining the edition and executable details with each finding. A timing value from one build shouldn't quietly become a claim about every version.\n\nThe recovered calculations and state changes are first turned into small C++ reference models and tests, then integrated into NullG. The notes keep track of what came from the executable, what was adapted, and what was observed in the engine. Players supply their own game files; I'm developing original NullG content separately.\n\n## Other reconstruction projects\n\nThis was happening while agent-assisted software reconstruction was getting much more attention. [Coverage of REA's growth](https://www.onfirstlaunch.com/blog/reverse-engineer-anything-rea-explained) described the interest around demonstrations of agents inspecting applications and reproducing their behavior.\n\n[ArtCraft's projects](https://github.com/storytold) include photo, video and PDF tools, with [WordCraft](https://github.com/storytold/wordcraft), [GridCraft](https://github.com/storytold/gridcraft) and [DeckCraft](https://github.com/storytold/deckcraft) targeting Word, Excel and PowerPoint-style work. [October coverage](https://www.techradar.com/computing/office-suites/developer-who-vibe-coded-free-adobe-clones-reveals-apps-to-take-down-microsoft-office-next-and-says-there-is-no-reason-to-save-broken-software) connected those AI-assisted projects with interest in alternatives to Adobe and Microsoft software.\n\nThe work is similar in one respect: study how something behaves, implement it, then check whether it matches. With racing behaviour, that means taking the executable research into tests and the native inspectors.\n\n## Blender models\n\nThe first concrete use of those Blender MCP ideas was preparing original menu models. The assistant could inspect the scene, edit individual parts, export a candidate and produce comparison views in the same task.\n\nThe process starts with visual references and generated models where useful, followed by a Blender finishing pass. That covers shape, individual parts, surface cleanup, materials and polygon count. Saved revisions and repeatable exports make it possible to change one part and compare it with the previous version.\n\n![Four Blender review renders of the original monitor-shaped Graphics menu model](/content/images/2026/10/nullg/intro-blender-graphics-model.png)\n\nThe model is then checked in NullG's Model Viewer and menus at its intended size. The source files, exports and comparison images are saved for each revision. A Blender viewport is useful, but the asset still has to work under the engine's lighting and at the size a player will see it.\n\n## Recording races\n\nNullG can record a race, replay it with cinematic cameras and export video with titles and audio. The camera can follow a ship or cut to action elsewhere in the field. Landscape, portrait and square output cover the longer videos and shorter clips.\n\n\u003ciframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/tREm0SM8zmg\" frameborder=\"0\" allowfullscreen\u003e\u003c/iframe\u003e\n\n*The XL cinematic race intro.*\n\nThe screenshot tools cover menus, starting grids, tracks and weapon effects too. Agents can select and organize the captures with their settings and source details. A recorded race can be reviewed first, then used for footage in an update.\n\n## Learning pilots\n\nThere are two different uses of AI here. The development agent works on code and tools; the learned pilot is a model selecting controls during a race.\n\nThe pilot gets information about speed and direction, road geometry ahead, nearby ships and pickups. It selects throttle, steering, airbrakes, pitch and weapon commands, which enter the simulation as player-style inputs.\n\nTraining uses Python, Gymnasium, Stable-Baselines3 and PyTorch, with PPO as the learning algorithm. Native workers run NullG's race simulation, allowing several driving attempts in parallel while training updates the model.\n\n![RL evaluation replay on Gare d'Europa](/content/images/2026/10/nullg/intro-rl-city-race.png)\n\nA short run checks the setup and controls. Longer runs save checkpoints for evaluation on selected tracks and race configurations. Settings and seeds are retained so the checks can be repeated.\n\nThe evaluations measure completion, time, damage and steering smoothness. Traffic and combat runs also look at placing, pickups and weapon timing. A checkpoint is just a saved stage of training; it still needs evaluation before being approved for gameplay.\n\nReplays help explain the numbers. A chase view shows the ship working through a corner, while an overhead view shows the surrounding traffic. Both can be compared with the controls and metrics recorded during the race.\n\n![Overhead RL evaluation replay with colored racer markers](/content/images/2026/10/nullg/intro-rl-overhead.png)\n\nThe exported pilot runs in native C++, with Python handling the training. Saved checkpoints can be compared using the same race setup, and agents can run those comparisons and prepare the replays for review.\n\n\u003ciframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/fkUTwW2p_8k\" frameborder=\"0\" allowfullscreen\u003e\u003c/iframe\u003e\n\n*An AI-driving training clip from the NullG playlist.*\n\nThe [reinforcement-learning page](https://projectable.me/projects/nullg/reinforcement-learning/) covers the training integration, and the [MCP tooling page](https://projectable.me/projects/nullg/mcp-tooling/) describes the inspection tools.\n\n## Keeping the project updated\n\nI'm also using the agent-assisted workflow for projectable.me. The agent starts with git history, project documentation and relevant captures, prepares an illustrated article and saves a draft. I can then review and edit it on the site before publication. This post was prepared that way, using repository history for the timeline and existing engine captures for the images.\n\nThere’s now a playable racer underneath all this tooling: weapons, computer-controlled opponents, local split-screen, LAN and private online rooms.\n\n![Two-player vertical split-screen racing with WipEout XL content in NullG](/content/images/2026/10/nullg/intro-xl-splitscreen.png)\n\nOriginal ships and tracks, sound, and handling for gamepad and simulator use remain part of the longer-term work. Motion output, positional audio and multiple displays are still part of the pod plan.\n\nThe [project pages](https://projectable.me/projects/nullg/) have the engine details, the [video playlist](https://www.youtube.com/playlist?list=PLaR-_mRLlb6E) has development footage, and further updates are collected in the [project blog](https://projectable.me/projects/nullg/blog/).\n","html":"\u003cp\u003eI\u0026#39;ve been building an anti-gravity racing engine called \u003ca href=\"https://projectable.me/projects/nullg/\" rel=\"nofollow\"\u003eNullG\u003c/a\u003e.

The camera can follow a ship or cut to action elsewhere in the field. Landscape, portrait and square output cover the longer videos and shorter clips.\u003c/p\u003e\n\u003ciframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/tREm0SM8zmg\" frameborder=\"0\" allowfullscreen=\"\"\u003e\u003c/iframe\u003e\n\u003cp\u003e\u003cem\u003eThe XL cinematic race intro.\u003c/em\u003e\u003c/p\u003e\n\u003cp\u003eThe screenshot tools cover menus, starting grids, tracks and weapon effects too.

Surprisingly, SteamOS installed on it without any issues.\n\n![](/content/images/2017/11/IMG_1989.jpg)\n![](/content/images/2017/11/IMG_1988.jpg)\n\nAfter playing around with SteamOS and [Dirt Rally](https://www.dirtgame.com) on the [MinnowBoard](https://minnowboard.org) without much luck (talking in frames per minute, not frames per second), I settled on the idea of building a full Intel powered system running SteamOS. I would then work on designing and 3D printing the entire enclosure from scratch. \n\n\n###The Dirt Rally Car-cade!\n\n####Inspiration\nInitially I was going to design it with cues from the Audi Quattro, but I very quickly switched over to the 1995 Subaru Impreza, which is my preferred car in the game. \n\n\u003cp align=\"center\"\u003e\n![](/content/images/2017/11/IMG_2580.jpg)\n\u003c/p\u003e\n\nI ordered the smallest motherboard I could find that had the features I needed, along with the rest of the components that I didn't already have. \n\n####System Components\n* Motherboard: [Asus H110S2/CSM](https://www.newegg.com/Product/Product.aspx?Item=N82E16813132897)\n* CPU: [Intel G4500](https://www.newegg.com/Product/Product.aspx?Item=N82E16819117624)\n* CPU Cooler: [SILVERSTONE NT07-115X](https://www.newegg.com/Product/Product.aspx?Item=N82E16835220067)\n* Ram: [G.SKILL Ripjaws 8GB](https://www.newegg.com/Product/Product.aspx?Item=N82E16820232146)\n* Storage: [Samsung 950 Pro M.2](https://www.newegg.com/Product/Product.aspx?Item=N82E16820147467)\n\n####Other Components\n* LCD: [7\" 1024x600 capacitive touch LCD](https://www.ebay.com/itm/7-Inch-HDMI-Capacitive-IPS-Display-LCD-for-Raspberry-Pi-1024-600-/262941998848?roken=cUgayN\u0026soutkn=unc8RL)\n* USB Controller: [Pimoroni Picade Controller PCB](https://www.adafruit.com/product/2708)\n* 2x Speakers: [3W enclosed speaker from Adafruit](https://www.adafruit.com/product/3351)\n* Push Buttons: [Pack of 10 black pushbuttons](http://a.co/cee6jZP)\n* Potentiometer: [Pack of 5 10k ohm linear potentiometers](http://a.co/blt4qxJ)\n\n####The Design Process\nThe process of designing and printing was an iterative one. I initially designed and iterated the steering and throttle components until I was happy with how they worked. The USB controller interface is managed by a [Pimoroni Picade PCB](https://shop.pimoroni.com/products/picade-controller-board) (it's basically an arduino with an onboard amplifier for speakers). The steering and throttle are analog inputs using potentiometers. The steering wheel and throttle both self center (kindof) using rubber bands integrated into my design.\n\n![](/content/images/2017/11/IMG_2022.jpg)\n![](/content/images/2017/11/IMG_2047.jpg)\n![](/content/images/2017/11/IMG_2096.jpg)\n![](/content/images/2017/11/IMG_2105.jpg)\n![](/content/images/2017/11/IMG_2106.jpg)\n\nI then went about planning the smallest footprint possible for the Car-cade... Ensuring that I was able to 3D print everything using my Anet A8.\n\n\u003cp align=\"center\"\u003e\n![](/content/images/2017/11/IMG_2114.jpg)\n![](/content/images/2017/11/IMG_2115.jpg)\n\u003c/p\u003e\n\nAs I worked through designing each part and printing it, I got a better picture of how everything would come together. It didn't take much effort once the ball was in motion.\n\n![](/content/images/2017/11/IMG_2182.jpg)\n![](/content/images/2017/11/IMG_2262.jpg)\n\n####Social Media Interest\nI recorded a video of my friend Eric playing on the Car-cade and put it up on Twitter showing off the progress. A few large social media publishers contacted me and asked if they could share the video. It got quite a lot of views on their networks!\n\n\u003ciframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/Ss-si82NqcI\" frameborder=\"0\" allowfullscreen\u003e\u003c/iframe\u003e\n\n####Designing Around the Parts\nEverything was designed around being as small as possible. As you can see, minimal clearance was given around the motherboard. I had a balancing act between the maximum print area on my 3D printer and how much room I needed for cables plugging in to the motherboard.\n\n![](/content/images/2017/11/IMG_2342.jpg)\n![](/content/images/2017/11/IMG_2343.jpg)\n![](/content/images/2017/11/IMG_2344.jpg)\n\nOnce I had all the components finished and the first prototype assembled I went on to experiment with finishing methods.\n\n![](/content/images/2017/11/IMG_2359.jpg)\n![](/content/images/2017/11/IMG_2360.jpg)\n\n\n####Post-Processing\nInitially I thought that I should sand, primer, paint, then clear coat. I managed to pick up a can of World Rally Blue paint. It looks amazing... But after attempting the process I realized it was too much effort to go to for a project of this size.\n\n![](/content/images/2017/11/IMG_2467.jpg)\n![](/content/images/2017/11/IMG_2474.jpg)\n![](/content/images/2017/11/IMG_2526.jpg)\n![](/content/images/2017/11/IMG_2523.jpg)\n\n\n####Project Recognition\nIt was at this time that I received a package from Codemasters!!! I got sent SWAG!!\n\n![](/content/images/2017/11/IMG_2531.jpg)\n![](/content/images/2017/11/IMG_2533.jpg)\n![](/content/images/2017/11/IMG_2534.jpg)\n![](/content/images/2017/11/IMG_2535.jpg)\n\nMany thanks to the Dirt team at Codemasters. It's awesome to see them support the community the way they do!!\n\n\n####Post-Processing, Part 2\nAfter a lot of debating about the pros and cons of extensive post processing to finish 3d prints, I decided to switch to printing the parts using **different colored filament**. This process took a **LONG** time. I experimented with 4 different rolls of blue filament alone.

There were a few other shortcomings: it was uncomfortable, it flexed and squeaked, the rear traction loss wasn't smooth, the rear speakers flopped around like crazy, and so on...\n\n![](/content/images/2017/06/IMG_0349.jpg)\n\nI decided to spend a little while thinking about how to best resolve the big issues, and turned to Fusion360 to design a quick mockup of the main features.\n\n\u003cp align=\"center\"\u003e\n![](/content/images/2017/06/IMG_0607.JPG)\n\u003c/p\u003e\n\nThe new design became the basis of what I ordered from [80/20 Inc](https://8020.net): Extrusion, linear movement components for the sliding top frame, and the hinges for the steering bracket.\n\nOnce the extrusion arrived, I quickly mocked up how everything would fit together and came up with an implementation plan.\n\n![](/content/images/2017/06/IMG_0855.jpg)\n![](/content/images/2017/06/IMG_0856.jpg)\n\nStarting with the lower frame, I came up with a process of thread tapping, drilling, and milling to piece everything together.\n\n![](/content/images/2017/06/IMG_0876.JPG)\n![](/content/images/2017/06/IMG_0877.jpg)\n\nUsing a mill bit in my drill press, I was able to notch out the recesses so that the bolt heads sat flush to the edge of the extrusion.\n\n![](/content/images/2017/06/IMG_0881.jpg)\n![](/content/images/2017/06/IMG_0880.jpg)\n\nThis worked out nicely, although my drill press was a little too loose to provide the most accurate cutting. The drill shaft moved all over the place, leaving some of the recesses a little out of alignment.\n\nNext was building the mid frame joint. The lower and mid frames were attached together using a GM wheel hub that I picked up on eBay for $20 shipped.\n\n![](/content/images/2017/06/IMG_0879.jpg)\n![](/content/images/2017/06/IMG_0886.jpg)\n\nI designed this in Fusion360 and milled it using the CNC that I built.\n\n![](/content/images/2017/06/IMG_0888.JPG)\n![](/content/images/2017/06/IMG_0890.jpg)\n![](/content/images/2017/06/IMG_0891.JPG)\n\nOnce that was done, I was able to thread tap the extrusion for the mid frame and pre-assemble it.\n\n![](/content/images/2017/06/IMG_0892.jpg)\n![](/content/images/2017/06/IMG_0894.jpg)\n\nI then attached this section of the mid frame to the lower frame. I used long threaded bolts so that I could adjust the height that the mid frame sat on the lower frame.\n\n![](/content/images/2017/06/IMG_0895.jpg)\n![](/content/images/2017/06/IMG_0897.jpg)\n![](/content/images/2017/06/IMG_0900.jpg)\n![](/content/images/2017/06/IMG_0902.jpg)\n![](/content/images/2017/06/IMG_0903.jpg)\n\nThe top frame was then mocked up. The top frame sits on linear sliders to allow it to slide back and forward. This was the biggest improvement over version 1.\n\n![](/content/images/2017/06/IMG_0912.jpg)\n![](/content/images/2017/06/IMG_0917.jpg)\n\nThere was a lot of drilling and thread tapping to get all the pieces of the top frame together.\n\n![](/content/images/2017/06/IMG_0920.jpg)\n![](/content/images/2017/06/IMG_0930.jpg)\n![](/content/images/2017/06/IMG_0931.jpg)\n![](/content/images/2017/06/IMG_0936.jpg)\n\nI pieced together a seat mount using 80/20, rather than using the SimXperience DIY seat kit that I had for version 1. I did this so that I could get the seat sitting lower in the frame.\n\n![](/content/images/2017/06/IMG_0941.jpg)\n![](/content/images/2017/06/IMG_0946.jpg)\n\nI found a great universal joint on eBay for $30. With this wing style U-Joint, I had a lot more flexibility with how I mounted things. I had to make a quick and dirty jig to get the hole spacing correct as the holes ended up being right along the edge of an extrusion.\n\n![](/content/images/2017/06/IMG_0944.jpg)\n![](/content/images/2017/06/IMG_0947.jpg)\n![](/content/images/2017/06/IMG_0949.jpg)\n\nI also had to notch out part of the extrusion on the mid frame to allow the U-Joint bolts to sit down further at the extreme angles.\n\n![](/content/images/2017/06/IMG_0950.jpg)\n![](/content/images/2017/06/IMG_0951.jpg)\n![](/content/images/2017/06/IMG_0952.jpg)\n![](/content/images/2017/06/IMG_0953.jpg)\n\nWith the seat mounted, I then focused on the rear rollers for the traction loss mechanism. These rollers ultimately set the height of the mid frame from the lower frame. I designed the brackets in Fusion360 and milled them on my CNC.\n\n![](/content/images/2017/06/IMG_0988.jpg)\n\nI used track rollers that I found on eBay. They were called LR200NPPU Track Roller Double Row Bearing Sealed 10x32x9 Track Bearings 18165. I got 4 for $20.\n\n![](/content/images/2017/06/IMG_0986.jpg)\n![](/content/images/2017/06/IMG_0992.jpg)\n![](/content/images/2017/06/IMG_0993.jpg)\n![](/content/images/2017/06/IMG_0994.jpg)\n\nI then mounted them on the cross member of the mid frame.\n\n![](/content/images/2017/06/IMG_0995.jpg)\n![](/content/images/2017/06/IMG_0996.jpg)\n![](/content/images/2017/06/IMG_0997.jpg)\n\nWith the mid frame leveled, I went back to the seat to mount the actuator mount bracket. This was tricky. I had to notch and drill at an angle in the extrusion (98 degrees).\n\n![](/content/images/2017/06/IMG_1007.jpg)\n\nI then designed and fabricated some side support brackets to help relieve the 3 bolts that went into the base extrusion on the seat.\n\n![](/content/images/2017/06/IMG_1011.jpg)\n![](/content/images/2017/06/IMG_1012.jpg)\n![](/content/images/2017/06/IMG_1013.jpg)\n\nI had to design and fabricate end caps for the extrusion that would allow me to thread tap for the actuators. This was the thickest aluminum stock that I had milled on my CNC at the time. Everything went ok-ish... Mid job the x-axis coupler came loose and the CNC started to dig into the piece. I was able to stop it and recover the job without any major damage.\n\n![](/content/images/2017/06/IMG_1015.jpg)\n![](/content/images/2017/06/IMG_1016.jpg)\n![](/content/images/2017/06/IMG_1020.jpg)\n![](/content/images/2017/06/IMG_1023.jpg)\n![](/content/images/2017/06/IMG_1027.jpg)\n![](/content/images/2017/06/IMG_1028.jpg)\n![](/content/images/2017/06/IMG_1029.jpg)\n![](/content/images/2017/06/IMG_1032.jpg)\n![](/content/images/2017/06/IMG_1033.jpg)\n![](/content/images/2017/06/IMG_1034.jpg)\n![](/content/images/2017/06/IMG_1035.jpg)\n\nThe rear traction loss actuator needed a pair of brackets. Again, designed in Fusion360, then milled on my CNC.\n\n\u003cp align=\"center\"\u003e\n![](/content/images/2017/06/IMG_1044.JPG)\n\u003c/p\u003e\n\n![](/content/images/2017/06/IMG_1049.jpg)\n![](/content/images/2017/06/IMG_1046.jpg)\n![](/content/images/2017/06/IMG_1051.jpg)\n![](/content/images/2017/06/IMG_1052.jpg)\n![](/content/images/2017/06/IMG_1053.jpg)\n\nI marked and drilled out the mounting plate for the steering wheel. This was just a piece of stock that I purchased from [80/20 Inc](https://8020.net).\n\n![](/content/images/2017/06/IMG_1037.jpg)\n\nThen designed and milled the brackets for the steering height adjustment.\n\n![](/content/images/2017/06/IMG_1055.jpg)\n![](/content/images/2017/06/IMG_1056.jpg)\n![](/content/images/2017/06/IMG_1060.jpg)\n![](/content/images/2017/06/IMG_1061.jpg)\n\nMounting the shifter and handbrake was pretty straight forward. I was able to use 80/20 components for the shifter and I re-used the version 1 handbrake mount with slight modification.\n\n![](/content/images/2017/06/IMG_1075.jpg)\n![](/content/images/2017/06/IMG_1076.jpg)\n![](/content/images/2017/06/IMG_1077.jpg)\n![](/content/images/2017/06/IMG_1079.jpg)\n\nThe transducers mounted directly using 80/20 components.\n\n![](/content/images/2017/06/IMG_1080.jpg)\n![](/content/images/2017/06/IMG_1081.jpg)\n![](/content/images/2017/06/IMG_1082.jpg)\n![](/content/images/2017/06/IMG_1083.jpg)\n\nThe final finishing parts came in from [80/20 Inc](https://8020.net): some HDPE for the backend to roll on, plastic end caps, and cable management mounts. I had to make a few minor adjustments to things, but in the end it all came together nicely!\n\n![](/content/images/2017/06/IMG_1135.jpg)\n![](/content/images/2017/06/IMG_1136-1.jpg)\n![](/content/images/2017/06/IMG_1137.jpg)\n![](/content/images/2017/06/IMG_1138.jpg)\n\n\nHere is the first video of the new rig in action. This is me playing Assetto Corsa in VR.\n\n\u003ciframe width=\"560\" height=\"315\" src=\"https://www.youtube.com/embed/-HftO5CsJCQ\" frameborder=\"0\" allowfullscreen\u003e\u003c/iframe\u003e\n\n\n----\n\n#### Update 6/25/2017: 4 point racing harness.\n\n![](/content/images/2017/06/IMG_1243.jpg)\n\nI decided that I needed a racing harness to add to the realism in VR. The harness is mounted to the mid frame with some spring tensioning. When you brake, the seat moves forward, but the harness stays in place, so you feel as if you are being held back by the harness, as you would in a real car. Its a really great experience.\n\n![](/content/images/2017/06/IMG_1244.jpg)\n![](/content/images/2017/06/IMG_1247.jpg)\n\nI CNCed a small bracket to mount the springs to the 80/20. The other side of the springs went on to the harness rear mounts, and the harness side mounts went directly on to the seat side brackets.\n\n![](/content/images/2017/06/IMG_1246.jpg)","html":"\u003cp\u003eI have really enjoyed having a motion simulator platform for sim racing.
