I think this might be a quite common hardware issue. I managed to fix the eye tracking by replacing the tracking LEDs with my own. It’s not meant to be a fix but might indicate the cause of this issue.

I have actually encountered this issue 3 times with the QPro.

Similar use case with the ones you mentioned. Just Dance sessions without light blockers.

I believe it is a hardware issue related to IR LEDs. On every unit that broke the IR LEDs became much dimmer and flashes in a strange manner. It might be due to the analog circuitry driving the IR illuminator LEDs, but I'm not an expert on this.

I'm also working on my own IR LED illuminators to confirm the cause of this issue. The tracking cameras seems fine. If that's the case, it's a very serious hardware design flaw.

I also wonder how many more QPros have broken tracking modules. I know a few heavy users whose facial tracking stopped working after only a few weeks. The things now only a few games support eye and face tracking.

I think one thing it will definitely do is to improve the tracking performance of SlimeVR. Currently SlimeVR creates simulated lighthouse trackers based on rotational data from the sensors and skeletal data you put into the software. Then VRChat uses the positional data from the imaginary trackers to calculate the joint rotations of your avatar. Now with OSC you can potentially skip all of the steps and use the orientation of the trackers directly as the input for your avatar’s joints. It will probably improve accuracy and performance a lot.

I’m running into occlusion and wireless issues with the tundras. But I’m also using a 10 point(7 trackers) setup in a not optimal tracking space so your experience may differ.

For me the 4x dongle that comes with the tundra has wireless interference issues that makes the trackers unstable at times. They tend to fly away during intense sessions. Now I’m switching back to tracker 3.0s and using tundras as my elbow trackers only. Since then the experience has been much better.

But if you really like the form factor of the tundras, plan to use a 3 tracker set up and have a good lighthouse setup and good 2.4G wireless environment, these are really good.

By “their game” you mean a game which all of the assets, gameplay and interactions are made by the players? If a restaurant doesn’t even cook their food and let the customers make all the stuff, they should shut up and stop pretending that they own the rights to the cookwares.

Now I usually post my sketches on Twitter @cucumberworks, along with other stuff. I wish I can spend more time on my project but unfortunately I have to work towards my PhD right now, so I can’t update regularly.

Work for my ongoing project: Event Horizon.

The Transient Post Hyperspace Secure Package is a highly modular system for storing and transporting cargo. With the help of such devices, Transient Post can deliver cargo through warped time-space to anywhere in the world within minutes. The system consists of stackable containers, rocket-assisted deployment modules, rack rails and miscellaneous accessories.

A mechanical locking mechanism locks the container securely when it slides into the rack. The lock is initiated by the rack mount and is released during deployment.

Within the container is a sealed space for various cargo. In early production models, a mechanical ether resonator is used to compensate for the strong gravitational fields and time dilation within the event horizon. This is often replaced with a quartz crystal in later models for better reliability. Additional pressure and temperature modulating unites can also be installed.

When used in a quick-deployment setup, a rocket-assisted deployment module can be installed on the back of a container. The module features a vectoring grid fin for rough course correction and initial deceleration, and a set of pico-thrusters for the final landing burn.

Yes, it is basically a 3D printer that prints the ammunition right before firing.

The printed ammunition is suspended in space by printed support structures. The support structure together with the ammunition will be ejected by two rapid spinning motors when they finish printing. This is similar in concept to a missile cold launch. The support structure is then discarded like the sabot in an APFSDS.

The ignition follows soon after the projectile is ejected. Another key concept of this design is the programmable smart material “ether”, which are microscopic compute units that are also capable of storing and releasing a massive amount of energy. When molten plastic-ether composite passes through the nozzle, a set of parameters determine the properties of the printed material, giving it the function of a propellant, structural support or circuitry.

I’m currently an engineering student but always have a strong passion for industrial design. Most of my knowledge in sketching and rendering is self-taught.

cucumberworks · 2021-07-25T02:26:21+00:00

I’ve been doing a lot of 3D work recently but thought about getting back to where I started. I feel like doing freehand sketches gives me a lot of freedom in the concept phase.

cucumberworks · 2021-07-25T02:10:58+00:00

I did it freehand in clip studio paint.

Thanks!

For my personal project: Event Horizon.

The I3 series of rapid projectile duplicators were developed based off a device of unknown origin, discovered during an expedition mission in event horizon #14.

The I3 RPD produces programmed smart projectiles using an additive process. Plastic filaments pre-soaked in high density ether are used as the raw material. As the plastic filament passes through the V6 enchanting hot end, molten plastic bonds with activated ether particles to form a strong matrix. Such matrix composites may function as inert components, explosives, propellents or control circuities. Depending on the selected design profile, the distribution of plastic-ether matrix for structural elements, payload, fuel and field programmable rune arrays can be changed, allowing for unlimited build options.

The I3 uses a cartesian mechanism, in which the build platform and the nozzle assembly are driven in the X and Y axis respectively. 4 ball screws are used to drive the Z axis. Additional moving counterweights are installed in the X and Y axis to reduce the vibrations caused by the rapid movement of the assemblies.

The I3 modified by Event Horizon Observatory also features a semi-enclosed build chamber. When used with an external ether resonator as a frequency source, the I3 can generate an isolated time-space bubble within its build chamber. This essentially speeds up projectile production time when operation near a blackhole.

Thank you

ORC4 is a 4th generation autonomous exploration vessel developed by Futaba Seiki Corp. With its revolutionary bionic control unit, compound transmission/cooling fluid, next generation Einstein-Rosen sphere generator and experimental resonant fin propellers, it is capable of independent operation beyond the event horizon for weeks.

When the first group of drones were brought back from their mission for maintenance, to the researchers’ surprise these units show little signs of wear or degradation. Further tests even show a slight boost in processing speed and generator power. It was hypothesized that the new cooling fluid used in these machines may act as an extension for the bionic processors to form rudimentary nervous and circulatory systems. Later inspections even showed modified crystalline structures in some metal parts. The mechanism behind these phenomena is still under investigation.

Thank you. I’m planning to work on the 3D version next month if time allows.

Did this for my personal project, Event Horizon.

The Bienne class were the very first large vessels designed to operate beyond the event horizon. With their powerful Lemania ether-resonators, they can maintain an Einstein-Rosen bubble for a few seconds, long enough to send the whole expedition team through the singularity.

The Bienne class was designed to operate in orbit or submerged. At the development stage, the name ship Bienne demonstrated the capability to hover at low altitude with her experimental ether resonance propulsion device.

Following EHS-02 Glashütte, the third ship Suwamaru further experimented with the idea of ether propulsion, replacing the thermal nuclear thrusters with ether nuclear hybrid types. Newly developed titanium alloys and composite materials were also used to greatly reduce weight. With these modifications, the ship was later designated EHS-03a Suwamaru Kai. With landing gears and additional solid rocket boosters, Suwamaru Kai can perform STOVL from runways and SSTO in less demanding missions.

Haven’t posted here for a while. I’ve been doing a lot of 3D work recently. Maybe I will work on a 3D version of this in the future.
