Halloween costumes can be anything from expensive authentic entertainment to a character’s clothing, to cheap imitations bought at one of those overcrowded pop-up stores. Alternatively, you can be creative and conceptual about things, Like building a pedestrian sign costume.
create the [jared531]The design uses a large piece of cardboard painted black as a base. This is located behind the wearer, and is given a yellow outline to simulate common pedestrian signals in the United States. Then the red fairy lights are placed on half of the cardboard with a pattern that mimics the hand signal “STOP”.
The wearer must then wear all-black clothing, and attach the flat cardboard board to themselves with rubber bands. The black mesh face covering helps complete the look by blending the wearer’s face. They are then equipped with white fairy lights around their bodies, to simulate the “WALK” signal.
It’s a simple concept, but it accurately repeats a typical pedestrian sign. It’s definitely something we’ve never seen before, and it’s impressive in this age of the internet when anything new becomes old again just minutes later.

There are a couple of Outlook vulnerabilities that we’ve been tracking Finally, along with another handful of fixes this Tuesday, a total of six are 0 day gaps. The third vulnerability was also zero-day long, and was discovered by Google’s Threat Analysis Group. This resulted in arbitrary code execution when a Windows client connects to a malicious server.
Fixed a pair of privilege escalation flaws, one being another issue with the print spooler, and the other with the key-handling service. The final zero-day fix was to bypass the web tag, which is the tag that is added to a file’s metadata to indicate that it was downloaded from the Internet. If you deliver malware inside an ISO file or it is marked as read-only in a zip file, the warning will not appear on execution.
Will Typosquat for Bitcoin
A trend that isn’t showing signs of slowing down is Typosquatting, the simple malware distribution strategy of loading contaminated packages using misspelled variants of legitimate package names. The latest scheme like this, Discovered by researchers at PhylumCrypto was stolen in Python packages. These packages are hosted on PyPi, under names like

If you’ve ever seen these gadgets with “breathing” LEDs and wondered how to do it, then [DIY GUY Chris] can show you how Design your own surface versionusing only analog electronics.
The circuit itself is built around a slow, triangular wave oscillator, which works to bump the current up and down the LEDs to make it look as if the lights are breathing in and out. The overall effect is rather satisfactory, and the oscillation speed can be adjusted using the onboard potentiometer.
This project is actually an update of the previous version that used the hole punch components (shown in the video below), and it shows that revisiting completed projects can give them a new lease of life. It also shows how easy it is to design and order custom circuit boards these days. Not so long ago, a project like this could have been created either on a bar plate or etched from copper-plated FR4 in an acid bubble tank!
If you have visited an old project that you are proud of and would like to show others, why not send us a message on our website advice line?
We’ve covered a few other options for breathing LED lights in the past, like this one digital logic versionAnd the Arduino library It has a bunch of other effects to choose from as well. Continue reading “Rooftop-mounted light breathes life into your project”
One of the great things about plastic is that it can be relatively flexible. We see things all the time sticking together, but when 3D printing, you don’t often come across designs that fit. [Engineers Grow] He has a video to help you Unbreakable snap fitting design.
In the first video you can see below, he addresses three parameters that can help. The first is the length of the snap element. Second, the cutting size can be reduced. You can also try to perform a hijacker; As thin as possible, although in the example he got very thin and ended up breaking a snap anyway.
The last suggestion, covered in detail in the second video below, is to change the material you’re using. The main parameter is known as the elongation at break. For PLA, the typical value for this is 8%. ABS is 10%, PETG is 24%, nylon is 100%. Simplistically, you can assume that a piece of PETG can deform up to 25% before it breaks. This may be true, but it will be permanently distorted long before then. The video suggests using 10 or 15% of the value to ensure that the part does not lose its shape.
In the third video, you will also learn that the direction of the typography is important. Making the hooks grow out of the build plate results in a weak hook as you might expect.
