Off the hop, we love portable consoles. To be clear, we don’t just mean handhelds like the 3DS, or RetroPie builds, but when a maker takes a home console from generations past and hacks a childhood fantasy into reality — that’s amore. So, it’s only natural that [Bill Paxton]’s GameCube re-imagined as a Game Boy Advance SP has us enthralled.
Originally inspired by an early 2000’s imagined mockup of a ‘next-gen’ Game Boy Advance, [Paxton] first tried to wedge a Wii disk drive into this build. Finding it a bit too unwieldy, he opted for running games off of SD cards using a WASP Fusion board instead. Integrating the controller buttons into the 3D printed case took several revisions. Looking at the precise modeling needed to include the L and R shoulder buttons, that is no small feat.
Sadly, this GameCube SP doesn’t have an on-board battery, so you can’t go walking about with Windwaker. It does, however, include a 15 pin mini-din VGA-style port to copy game saves to the internal memory card, a switching headphone jack, amp, and speakers. Check it out after the break!

A Raspberry Pi kicking around one’s workbench is a project waiting to happen — if they remain unused long enough to be considered a ‘spare.’ If you find you’ve been pining after an Alexa or your own personal J.A.R.V.I.S., [Novaspirit Tech] might be able to help you out — provided you have a USB mic and speaker handy — with an accessible tutorial for setting up Google Assistant on your Pi.
A quick run-through on enabling a fresh API client on Google’s cloud platform, [Novaspirit] jumps over to the Raspbian console to start updating Python and a few other dependencies. Note: this is being conducted in the latest version of Raspbian, so be sure to update before you get underway with all of your sudos.
Once [Novaspirit] gets that sorted, he sets up an environment to run Google Assistant on the Pi, authenticates the process, and gets it running after offering a couple troubleshooting tips. [Novaspirit] has plans to expand on this further in the near future with some home automation implementation, but this is a great jumping-off point if you’ve been looking for a way to break into some high-tech home deliciousness — or something more stripped-down — for yourself. Check out the video version of the tutorial after the break if you like watching videos of guys typing away at the command line.

Video game props require a dedicated maker with a repertoire of skills to create. When those props are pulled from the Mass-Effect universe, a little more technological mastery is needed. Bringing those talents to bear, [Optimistic Geometry] has built a motorized, folding M-3 Predator Pistol!
The gun was modeled in Fusion 360 and 3D printed on an Ultimaker 2 at the MAKLab Glasgow. [Optimistic Geometry] felt constrained by the laws of our reality, so opted for the smaller firearm thinking it would be an appropriate entry-level challenge. I’m sure you can guess how that went.
There wound up being three main build phases as well as a spring-loaded version to testing purposes. Throughout, [Optimistic Geometry] struggled with getting the parts to latch fully open or closed, as well as working with the small form factor. However, overhauling the motor design — and including some limiters lest it deconstruct itself — a custom latching circuit, and — obviously — a few LEDs for effect, produced a magnificent prop.

What’s the best way to image a room? A picture? Hah — don’t be so old-fashioned! You want a LIDAR rig to scan the space and reconstruct it as a 3D point map in your computer.
Hot on the heels of [Saulius Lukse]’s scanning thermometer, he’s replaced the thermal camera on their pan/tilt setup with a time-of-flight (TOF) camera — a Garmin LIDAR — capable of 500 samples per second and end up scanning their room in a mere fifteen minutes. Position data is combined with the ranging information to produce a point cloud using Python. Open that file in a 3D manipulation program and you’ll be treated to a sight like this:

Our friend [James Bruton] from XRobots has engaged in another bit of mixed-reality magic by showing how one can seamlessly step from the virtual world into the real world, and back again. Begone, green screens and cumbersome lighting!
Now, most of what you’re seeing is really happening in post-production — for now — but the test footage is the precursor for a more integrated system down the road. As it works now, a GoPro is attached to the front of a HTC Vive headset, allowing [Bruton] to record in both realities at the same time. In the VR test area he has set up is a portal to a virtual green room — only a little smaller than a wardrobe — allowing him to superimpose the GoPro footage over everything he looks at through that doorway, as well as everything surrounding him when he steps through. Unfortunately, [Bruton] is not able to see where he’s going if he is to wear the headset, so he’s forced to hold it in one hand and move about the mixed-reality space. Again, this is temporary.
In action — well, it gets a little surreal when he starts tossing digital blocks through the gateway ‘into’ the real world.

When operating any kind of hydroponic farming, there are a number of lighting solutions — few of them inexpensive. Originally looking for an alternative to the lighting of IKEA’s expensive hydroponics system, [Professor Fartsparkle] and their colleague prototyped a rail system that allows clip-on LED boards for variable lighting options.
Taking inspiration from wire and track lighting systems, the key was the 5mm fuse holders mounted on the bottom of the LED boards. Snipping off their stopping clip makes them easy to install and remove from the mounting rails. The rails themselves double as power conduits for the LED boards, but keeping them out of the way is easily done with the variety of 3D printed hangers [Professor Fartsparkle] has devised. Lighting is controlled by a potentiometer on the power injection board, as well as any home automation control via an ESP8266.
[Professor Fartsparkle] asserts that the boards can be slid along the rails without any noticeable flickering, but they do suffer from heat dissipation issues. That aside, the prototype works well enough that the 3W LEDs can be run at half power.
This is an ingenious — and cheap — workaround for when sunlight isn’t an option, but you are still looking for a solution capable of automation.
When makers take to designing furniture for their own home, the results are spectacular. For their senior design project, [Phillip Murphy] and his teammates set about building a smart table from the ground up. Oh, and you can also use it to play games, demonstrated in the video below.
The table uses 512 WS2812 pixels in a 32 x 16 array which has enough resolution to play a selection of integrated games — Go, 2-player Tetris, and Tron light cycle combat — as well as some other features like a dancing bird party mode — because what’s the point of having a smart table if it can’t also double as rave lighting?
A C2000-family microcontroller on a custom board is the brains, and is controlled by an Android app via Bluetooth RN-42 modules. The table frame was designed in Sketchup, laser-cut, and painstakingly stained. [Murphy] and company used aluminum ducting tape in each of the ‘pixels’, and the table’s frame actually forms the pixel grid. Check out the overview and some of the games in action after the break.
