The latest video from AsapSCIENCE, The War on Science, addresses the preverbal war between science and society we are experiencing today. 100, 200, or 1000+ years ago you could argue the ignorance of science was due to lack of information availability. However, that does not apply to today’s world. The entire World’s knowledge and the sum of collected data are available to virtually anyone, anywhere at any time. This moment isn’t just historical; it is pivotal. Yet. Society as a whole seems to continue the trend of ignoring this data in favor of emotional social media posts.
AsapSCIENCE’s take on the situation is spot on and worth not only the 5 minutes to watch but also sharing with the video everyone you know, and voting to support science, in your area.

Deck out the rest of your Ghostbuster gear with a Ghost Trap. Dustin McLean from DIY Prop Shop from AWE me builds a trap in this quick 12-minute video. The build uses very basic materials: cardboard, popsicle sticks, tape, PVC, and spray paint. Of course, the tools used are just basic cutting and straight edges.
If you aren’t familiar with DIY Prop Shop, the show–as the name suggests–takes a DIY approach to building famous movie props. Totally fun to watch and get ideas for your projects.
Check out the Ghost Trap Build on YouTube. Who you gonna call?
The latest AddOhms looks at why you need a pull-up resistor when using push-buttons. This video goes into what happens when you leave a pin floating, what a floating pin means, and how the pull-up works. You can get more information about the video on the AddOhms Episode page.
This tutorial is the 2nd time I’ve made a video on pull-ups. Despite being a single resistor, it can be a difficult topic for new hardware designers to understand. The pull-up video was the first video tutorial I ever made. In fact, the YouTube version uses YouTube’s “stabilization” algorithm, which gives the video a very warped feel.
AddOhms #15 shows improvements in skill over the past couple of years!
Back in the 1990s, a 1.44mb floppy disk was a reasonable storage size for most documents. For bigger documents or backing up an internal hard drive, other options were necessary. You might remember the Zip Drive, but that wasn’t the first large portable media.
The Bernoulli Box was the precursor to the Zip Drive. It used custom media that could store 10s to 100mbs on portable disks. Well, portable compared to carrying around an entire hard drive. Operating using the Bernoulli principal, the drive’s head never comes in contact with the “floppy” material inside the protective case.
Clint of Lazy Game Reviews takes a look at this cool forgotten drive technology in this video.
Using a learning algorithm known as NEAT, this Super Mario World play through is an example of a machine learning how to beat the level on its own. Using an evolutionary process, a neural network was built–or learned–to complete the level. The name of the program used to control Mario is called… Mar-I/O.
- N: Neuro
- E: Evolution of
- A: Augmenting
- T: Topologies
The initial play through is fascinating as well as the breakdown of what is going on. Well worth the 5 minutes.
[Update… Ryan in the comments provided this MarI/O version modified to factor in score.]
Learning to a breadboard is critical when adding electronics to a project. A skill often overlooked is how to use breadboard jumper wires correctly. For example, when I breadboard a circuit I only use Red, Green, or Blue for positive voltages and Black for ground. Other colors, it depends on the functions of the wire. The idea is to keep it clear when I look at the board, what each wire is doing.
This video from Make is a great overview of how to develop a skill, or habit, around using breadboard jumper wires in your circuit.

Today “regular” people will start receiving their pre-ordered Apple Watch. Whether they spent $350 or over $10,000 dollars, they’ll now have a device that connects to their iPhone and tells time. Like their iPhone does. But with Bluetooth!
What if you don’t want an Apple watch, but want to celebrate a real computing achievement? Check out this video on an Apple ][ watch. Oh and it is real.
That’s right, this isn’t just some clever movie-magic hoax. Following this Instructable, you can build your own Apple ][ Watch.
Most of the major electronic blogs have covered the controversy between Arduino LLC and Arduino SRL. My first deep look into it was from Hackaday’s Arduino v. Arduino. Since it has been covered so well by others, I won’t re-hash the already known facts.

element14 is running a Design Challenge called Enchanted Objects. The idea is to add magic, or modern technology, into older objects, enchanting them. How could you turn an ordinary household object into something extraordinary?

With my recent interest in retro-electronics, an entry by Jan Cumps caught my eye. He’s repaired a vintage record player (turntable) using an Arduino and Pulse Width Modulation (PWM) control. For more information on his work, the project page is here. Jan’s YouTube channel is at pitface123.
National Instruments changed the world of instrumentation when it released the VirtualBench. For about $2000 (USD), they give you a bench’s worth of equipment in a box about the size of Horowitz’s The Art of Electronics! In this video review, I take a look at the VirtualBench’s 6 built-in functions.
VirtualBench Review Jump Points
Here are jump points to specific parts in the review.
Overall, I like the box and I think you’ll see why. The iPad App is amazing. The specs are impressive. And overall, the instrument works well.
