Austin sent in this project he built. He added driving light/turn signals to his 2007 Honda CBR 1000RR. To get the job done he used a bunch of Adafruit gear and the Adafruit Bluefruit app!
My 2007 Honda CBR 1000RR has flush mounted turn signals meaning that it is hard for cars coming head on to see which way I am turning, this is especially difficult at 4 way stops when I want to turn left and the car in front of me thinks I am going straight. COVID-19 left me at home with my thoughts long enough that I decided to not only fix my problem, but have some fun with it as well. Many high end cars such as Audi, Lamborghini, and Ford Mustang have dynamic turn signals and LED accent lighting that I decided to recreate for my motorcycle.

When a gravitational wave ripples through the Earth, it will stretch one arm of LIGO while squashing the other. The light, which has a fixed speed and won’t warp with the rest of the world, then takes a different length of time to travel down each arm. The scientists can measure this difference to detect the wave.
The challenge is that the ripples caused by gravitational waves are minuscule since, despite appearances, gravity is a very weak force. In terms of the squashing and stretching, “we’re talking about these tiny, fractional changes,” says Demos, “roughly one-thousandth the size of a proton.”
tl;dw – I can get five 1 Gbps network interfaces using an Intel I340-T4 PCIe NIC, but I can only get a maximum of 3.06 Gbps throughput using all five interfaces at the same time.
You could use this setup to build a custom router or switch using OpenWRT or pfSense, or to run other specialized network setups for multiple-interface webservers, bandwidth metering, network bonding, or more!

Its operation is based on persistence of vision principle: you can drive one digit at time, so you must drive each digit at a speed so that human eye cannot perceive power off moments.
When using 4-digit 7-segment display, please notice that if it is common anode, the common anode pin connects to the power source; if it is common cathode, the common cathode pin connects to the GND. This guide is based on cathode one, nut anode works with the same code by inverting digit selection logic.

Unleash your inner Neo with this Pi based bullet-time set up. This array uses 15 Pis and 15 Pi cameras. The video does a good job of talking through the process and the final images are very cool!
We started to work on a PiCam version of our multi-camera software a few months ago, but that had nothing to do with our usual bullet-time work. It was mostly about photogrammetry, which should look like our DSLR system, with much smaller cameras. And that part is ready.
But as we had the equipment and the software I got interested to see how far we could push it with bullet-time and what kind of image quality I could get out of these tiny cameras. My main interest here is the size of them as they can be put super close to each other, giving me my best density ever on a multi-camera structure

Folks have been able to play DOOM on everything from a watch to a printer. Now here’s a project that brings a piece of DOOM into real life. Here’s more from Michael Darby via hackster.io:
I went to a store the other week and found a cool Skeleton in their Halloween section, I immediately thought; that’s got enough room in it for some hardware… images of a spooky cool Raspberry Pi/Arduino powered Revenant inspired Cyber-Skeleton came to my mind through a UAC-like portal….
Revenants in DOOM are basically cybernetically enhanced demon skeletons – you can find out more about these awesome things from here.

This plastic raven is enjoying a new after-life as a practical yet creepy security camera, the Raven Pi. It has a Raspberry Pi in its belly and a Pi Camera embedded in its neck, capturing HD video whenever motion is detected. At the same instant its piercing LED eyes light up, its servo-controlled head swivels back & forth, and it loudly plays either a random raven sound or an extract from Christopher Lee’s reading of The Raven.

Great background and project from Tyler on howchoo:
In order for the Bitcoin network to operate securely, it requires many additional full nodes to ensure the miners are following the consensus rules and help relay transactions to other nodes in the network.
And since there is no direct financial incentive to run a full node (unlike mining), it requires good Bitcoin citizens to step up and help out.
In this guide, we’re going to learn how to run a full node using a Raspberry Pi 4 and an external hard drive.

Martin Woodward of GitHub knows what really scares programmers: broken builds. So he’s created a project that uses a jack-o’-lantern to warn programmer’s about broken builds. Here’s more from Martin on Raspberry Pi Blog:
“When you are browsing code looking for open source projects, seeing a nice green passing build badge in the ReadMe file lets you know everything is working with the latest version of that project. As a programmer you really don’t want to accidentally commit bad code, which is why we often set up continuous integration builds that constantly check the latest code in our project.”
“I decided to create a 3D-printed pumpkin that would hold a Raspberry Pi Zero with an RGB LED pHat on top to show me the status of my build for Halloween. All the code is available on GitHub alongside the 3D printing models which are also available on Thingiverse.”

Just because you might only be partying within your bubble doesn’t mean you don’t want some pizzazz. These globes dance to the beat picked from reddit by Tom’s Hardware:
Each ball is equipped with an ESP32 module for wireless communication. The music beat is detected by the Pi—it sends a signal to one of the balls which communicates with the second ball using ESP NOW, a protocol used for communicating wirelessly with ESP32 chips. This causes the stepper motors to move the disco balls together to the beat of the music.

My Grandson came across an old Operation game that had no pieces so he asked me if I could print him some. I checked on line but only found the parts for other editions so I decided to make my own. I found a photo on the web of the parts but they were not straight on so I had to make adjustments for that.
These files are the result. I noticed that some of the parts were not oriented the same as the images on the game. I assume that the photo I used had some of the parts placed upside down. If you prefer a different orientation you can mirror the objects in your slicer.

Walking in a winter wonderland might be a couple months away, but there’s no time like the present to get started on your diorama. Shared by henryarnold on Thingiverse:
I resized the original design to be 1:48 scale so that 3.5″ is equal to a 14 foot high street lamp. This size matches the Dept. 56 Snow Village houses. I increased the size of the hole through the middle so that wires could be fed through.
I’ve just added the same lamp scaled for HO train layouts which is 1:87 instead of the 1:48 of Dept. 56 Snow Village Houses. The lamp parts for HO scale have “HO” in the name. The HO scale lamp design has a hole down the middle that will accept the grain of wheat lamps referenced below.

Helpful printing tips for folks who don’t like the waste from Joseph Flynt on 3DInsider:
Disposal of empty filament spools has been a perennial problem in 3D printing. It’s not unusual for a 3D printing firm to end up with hundreds of these empty spools in the space of a month. What can we do to avoid having these spools end up in a landfill?

I have seen several Star Trek TNG communicator badges on here, some more accurate than others. I really loved the setup by LoudMaker, which I remixed, here. His version seems to be the most screen-accurate. Once you sand and finish and paint them, it looks perfect. However, I was looking for a setup that is slightly less screen-accurate, but more durable, as I wear this on my lanyard at work every day. In the past I have had the nicely finished and painted ones, but of course the paint rubs off very quickly, and the piece looks pretty shabby very fast.

I can’t imagine why there might be a plague doctor or a mad scientist in the area, but if there is, this just might be the right prop. Shared by thom7215 on Thingiverse:
Print the tube in clear/natural PLA. The rest was printed all at once in black.\
There is a groove in the handle portion where part of a bamboo skewer will sit to aid in alignment of the two pieces. To line up the needle ring and needle cap, place the skewer in the holes of both pieces to line them up and glue them together.

Radical demon skull for all of your demon skull needs. Shared by Arkleseizure on Thingiverse:
I’m printing a bunch of these to give away on halloween, along with the candy. Last year I didn’t buy enough candy, so three little ghosts left empty-handed (but were too well behaved to egg my door). I still feel a bit guilty about that.
This is not an easy print, unless you cut the parts in creative ways and glue the pieces. See example in cut_pieces_X.stl.

For those interested in the construction, the O ring is a just superglued out of cord stock and the sensor wires are run through a 1/8-27 NPT hose barb and epoxied in place.
Designed for a maximum pressure of 150 PSI, the 1/2″ thick polycarb cover and 8x M3 bolts should be more than enough to keep things together. There is about 1lbf per PSI so at 150 lbf I didn’t bother with the math.
For social distant trick or treating, we thought we’d make a BLE controlled servo claw using the Circuit Playground Bluefruit.
We put our project on this flying ghost prop we got from our local halloween shop. It moves up and down along a rope that’s strung across our porch.
The servo is triggered using our mobile phone with the bluefruit connect app.

So I wanted a small MIDI keyboard (25 key). I found a decent Axiom 25 on Craigslist and bought it (wanted something older with 5 pin DIN MIDI out not just USB). It was in really great shape and works fine (I can’t say the same about my musical abilities).
So a few days later I see another Axiom 25 on Craigslist but for really cheap (almost free) cuz the keys don’t work… Figured at worst it would be spare parts.
Got it home and yes the keys mostly did not work. Pulled it apart and while it seemed to have been worked on there was evidence of some liquid spill of something mebbe a bit corrosive. Did some troubleshooting and eventually found that the traces in various locations on the keyboard PCB seem to have corroded away. In some cases it is kinda visible while in others not so much.
So I plan to try fixing up the various broken traces and see what happens.
One interesting side note is in brightening the keys, they found that beauty shops sell hydrogen peroxide gel, called Wella Cream, premixed and relatively inexpensive. The wrap in cellophane and put them in the sun process worked very well.
