Offworld, Episode 9: Isolation Trope in Sci-Fi Space Travel

This week on Offworld, we explore the trope of isolation and loneliness in science fiction space travel, and how both fictional and real-world astronauts cope with being away from home for extended missions. Joining us are neuroscientist Indre Viskontas and field geophysicist Mika McKinnon for a lively discussion on how sci-fi depicts the very real challenge of isolation in space!

Adam Savage's 2018 San Diego Comic-Con Schedule

Because he's currently shooting MythBusters Jr. for Discovery, Adam Savage's time at Comic-Con is shorter this year. But there are still plenty of opportunities to be part of his Comic-Con experience! Here's where Adam will be in 2018. (And stay tuned for our "friends of Tested" schedule as well.)

Syfy Wire Hosts the Great Debate (Thursday at 4:45 pm)

What superfan doesn't love a good debate? To reboot or not reboot? Have video games eclipsed movies and TV? Pine, Pratt, or Hemsworth? Felicia Day, Joe Manganiello, Adam Savage, Janet Varney, Orlando Jones and John Barrowman join the ultimate debate as they share their thoughts, feelings and theories on the genre's most hotly contested topics while moderator Aisha Tyler keeps the peace. After each round, you'll get to settle the debate by casting your vote for the most convincing argument.

Adam Incognito (Friday)

Be sure to follow @donttrythis on Twitter, because we'll Tweet when Adam is hitting the floor in costume. The first person to identify Adam will get two passes to his panel later that day.

Custom Keyboard Spotlight: Kailh Low-Profile 'Choc' Switches

Most keyboard switches currently in production are based on Cherry's classic designs, and even many of the others at least have support for Cherry-style keycaps. Kailh has a line of increasingly popular low-profile switches that eschew all that. The so-called "Choc" switches (AKA the PG1350 series) take up less space and offer interesting properties, but it'll be a pain to find keycaps.

As you can see in the photo below, these switches are less than half as tall as a standard Cherry-style switch. That means any keyboards built with Choc switches will be incredibly compact. These switches have a total travel of 2.4mm, substantially less than the 4mm or so that other switches have. They come in clicky, tactile, and linear variants just like larger switches. The tactile and linear switches also have a stabilizing wire inside to keep the stem centered.

The spring performance of Kailh low-profile switches are generally a bit lighter than their larger siblings. However, NovelKeys has worked with Kailh to create a line of "heavy" variants that come with 70g springs and different stem colors. The disassembled switch below is a Choc burnt orange variant from NovelKeys.

The most important difference here is the pin layout. Most PCBs won't accept Kailh Choc switches because the pins are over to one side of the housing. A few custom boards have support for these switches like the Planck Light. You have probably also noticed the stem lacks the Cherry cross connector. Because of stability and space issues, Choc keycaps use "prong" connectors that look a bit like AC plugs. There are a handful of keysets available for Choc switches, but the selection is minimal unless you want blanks.

In most switches, the legs on the stem give the switch its character. For example, a tactile bump comes from a physical bump on the legs. On Choc switches, the switch's properties are mainly thanks to the channel running up the middle. That piece makes contact with a plastic nub that moves the contact leaf to fire the switch. So, it's a bit like the BOX design but without sealed secondary compartment. The clicky switches also use a smaller version of Kailh's click bar design from switches like the BOX Pale Blue.

Ask Adam: Project from Hell

Every week, Adam takes a question from the Tested Premium Member community in the comments section below or on social media (tagged #AskAdamSavage) and answers here. This week, Adam talks about projects that were thought to be easy but ended up being a project from hell, and how he recovered.

PROJECTIONS, Episode 54: Mixed Reality with ZED Mini Camera

We visit the offices of Stereolabs, the makers of the ZED and ZED Mini mixed reality camera systems to test out their implementation of a passthrough camera accessory for VR headsets. Using their ZED Mini, we're able to get an augmented reality experience with the Oculus Rift and HTC Vive, and get a sense of the challenges of using a stereo camera system for passthrough AR.

Adam Savage's One Day Builds: EDC TWO Bag!

Adam's latest one day build is a very personal project: making a custom version of his new EDC TWO bag using the patterns he's putting out into the world. Marcos from Mafia bags stops by to guide Adam through some of the intricacies of sewing sailcloth and giving the bag a distinct look! (Patterns available at

Hobby RC: Testing the E-Flite UMX Timber

I've been a fan of ultra-micro RC airplanes since they first became available several years ago. At first, it was just about the cool factor of flying an itty-bitty model, even if it couldn't do much. But ultra-micros have advanced dramatically in recent years. They are now powerful, practical, and versatile flying machines with features that rival or surpass larger models. The subject of this review, the UMX Timber, is a prime example.

About the UMX Timber

The UMX Timber ($130) is a Bind-N-Fly model with a 27.6" (700mm) wingspan and a flying weight of only 4.3 ounces (121g). It comes with everything except a compatible radio transmitter, flight battery, and charger. Other than bolting on the landing gear and setting up your radio, all of the pre-flight tasks are done for you.

Like all of E-flite's other UMX models, the Timber is made of molded foam components. It is adorned with a mixture of paint and stickers. I'm not a fan of the stickers. While I like the color scheme, the stickers have a glossier sheen than the foam and are wrinkled in numerous areas. There is definitely some headroom for cosmetic improvement.

This model has a variety of bright LED lights installed in the wings and fuselage. They emulate the navigation lights found on full-scale airplanes. The lights are somewhat crude, with exposed wires and circuit boards. Their inclusion seems to be an afterthought. I'm sure some flyers like the lights. I wouldn't mind if they were omitted.

E-flite's UMX Timber is a small and lightweight RC airplane that is factory assembled.

One of the most noticeable and unusual aspects of the UMX Timber is the pair of cartoonish tires slung underneath. The tires seem a bit less awkward if you're familiar with the rugged full-scale airplanes made famous by Alaskan bush pilots. Those aircraft have similarly-oversized tires that let them take off and land on very rough ground. The UMX Timber's tires serve the same purpose. Whereas most micro-sized models require a paved runway or a hand launch, the UMX Timber is much less picky. I've been flying off of a grass runway with no problem. None of my other micros can do that.
