Virtual Desktop and Oculus Quest Tips & Tricks

Hey, Karl here. I wanted to share some experimenting I did with the Oculus Quest we purchased as a family gift for Christmas. One of the features I was looking forward to was wirelessly streaming VR games from my PC. It is not officially supported by Oculus but Virtual Desktop allows you to do this. Virtual Desktop is an app that can be purchased through the Oculus store. Unfortunately, there are a couple of steps that need to be taken to stream VR to the headset. Oculus forced VD to remove the emulated VR feature in its official store version. Once it is purchased you can then sideload the emulated VR version through Side Quest. Side Quest is a simple tool that makes sideloading apps easy and has a bunch of demo and games that aren’t in the Oculus store. The instructions are easy to follow on the Side Quest […]

Raspberry Pi 4 Powered Open Source Hardware Robot Paves the Way for Robot Maids

Raspberry Pi 4 Open Source Hardware Robot

Eventually, we all expect robots to do chores and other manual tasks performed by humans such as preparing and serving food at restaurants, carry objects over rough terrain as opposed to just inside the warehouse with a flat floor, or even moves pieces on a chessboard when other humans are no here to play with us. I’m fully expecting to eventually own a robot maid of sorts to wash dishes, mop the floors, and perform other tasks on my behalf. We are not there yet, but Raspberry Pi 4 powered Pollen Robotics’ Reachy open source-hardware robot is getting us closer to the goal as it can handle small objects and via two robotic arms and a dual-camera head, and can also interact with humans using a microphone and a speaker. Key features and specifications of Reachy robot: Main body SBC – Raspberry Pi 4 SBC with 2GB according to a […]

Fingerbot Bluetooth Mechanical Finger Enables Automation for most Home Appliances (Crowdfunding)

Adaprox Fingerbot Smart Home Automation Fingerbot is the place where IoT meets analog and creates a solution for smart home automation that works with Alexa, Google Home, Siri, and many smart home apps. What is Fingerbot? Adaprox, a team of engineers, programmers, and designers, designed the finger-sized device that can handle on/off for devices, repetitive motion tasks, toggles or switches. Fingerbot Does What? The little robot can work through voice or app, and can handle all activation and deactivation of traditional appliances, lighting and can even use its soft “finger” on a touchscreen for repetitive tasks in the home, all done mechanically. How Does It Work Fingerbot is designed to be attached to the device it is controlling with double-sided tape or velcro. This creates a firm grip on the surface so that its finger can control the device properly. The velcro option allows for switching Fingerbot between appliances, and […]
