Random final main

Random chance can set all kinds of activities into motion.  Remember Abed’s discussion of the dice role and its impact in Community?  Do you recall the potential impending doom as a kid shaking the Magic 8 Ball, one of the toys in the National Toy Hall of Fame?  Sure, you could settle with a coin toss or dice roll, but why?  How about mixing up your next Dungeons & Dragons event with something different?  Today we’re building a study model of a device that generates random numbers and provides different random results based on probability theory, including a 360 degree rotating octahedron that acts like an orrery, triggered by a button, with a rack-and-gear drive, overrunning clutch, and a driven wheel.  It’s the UGEARS Random Generator, the third model we’re testing after the 2-in-1 Arithmetic Kit (reviewed here) and the Gearbox (reviewed here).  The Random Generator is part of the model maker’s STEM Lab series, educational tools and fun models that aren’t just for kids.  This kit is full of surprises, and as it comes together you’ll see how science puts the “magic” in the Magic 8 Ball.

UGEARS Gearbox final

Today we’re building a study model of German engineer Karl Benz’s gearbox, the same mechanism you’d find in the transmission of any modern automobile, complete with drive shaft, layshaft with gear couplings, reverse idler, and a gear shift.  It’s the UGEARS Gearbox, the second model we’re testing after the 2-in-1 Arithmetic Kit (check out our first UGEARS review here).  The Gearbox is part of the model maker’s STEM Lab series, educational tools and fun models that aren’t just for kids.  Anyone who has ever driven a car should know the fundamentals of how a gearbox works, and this model is an excellent start.

You may have recently seen advertisements for UGEARS, maker of some incredible moving models made entirely from precision laser-cut plywood parts.  We laid our hands on several STEM Lab kits and are going to feature our builds of each model over the next few weeks.  These are projects that can be made generally in less than a day, and provide multiple avenues of entertainment and education.  Each model improves the maker’s ability to assemble a model, fun in itself, but like LEGO expert builder series models and Erector sets of the past, these models are engineering marvels that replicate machines for mathematics, physics, and engineering study.  More advances models in the catalog include working trains, cars, and a dragon with moving wings, which we’ll work up to.

First, let’s take a look at the Multiplier and Addiator builds, both included in the UGEARS 2-in-1 Arithmetic Kit (available here at Amazon and also via model shops and online game and craft stores) tools students from grade school through college engineering can use and display, featured as one of the starter builds in the UGEARS catalog.

MAND labs b

Review by C.J. Bunce

RadioShack was founded 100 years ago, and for most of those decades it has been the go-to supplier for anyone interested in electronics.  Not just for professionals, but it’s where students went to make things if they had even a remote interest in electronics.  The new incarnation of RadioShack is little different, less storefronts but an endless online supply of materials and ideas that what was once the exclusive purview of kids in the A/V Club.  It is now something any young person can–and should–become proficient in.  I knew as soon as I saw the Mand Labs kits on the new RadioShack website that this kind of product can and should be part of the future of STEM learning–whether at home or in schools.  So I reviewed the Mand Labs STEM Electronics Kit (KIT-1) to see if it’s as good as it looks. 

It is. 

Not only does the kit have everything you need–all the technological components to create more than 60 educational and fun projects–the even bigger value is the set of two textbook/workbooks, which provide all the theory, math, history, and core science so students understand the how and why.  With the books, digital videos, and online resources that come with the kit, even a young grade schooler can learn the fundamentals of electricity, physics, computer science, robotics, and electrical engineering.  And for adults, say you’re a cosplayer and you want to wire a helmet or chest box with lights and sound, or maybe you want to understand better why you can’t get your electronic fan or doorbell to work, or always wondered how the electric systems of your automobiles work, this kit will help you get started.
