This week on Maker Update: perfectly splitting cookies with science.
A realistic miniature brick wall, an epic three part table,
drip oilers for a steam engine, hypnotic wood spheres,
a hat that washes your hair, and designing better custom furniture.
Hi, welcome to Maker Update.
I'm Becky, back again to guest host.
Let's start off with the project of the week.
Ian Charnas created a device to help split Oreo cookies perfectly in half
and explains the science along the way.
He's got all the 3D printing files available in the Instructable
for his project, which was inspired by an MIT research paper.
The device holds the cookie with a chuck held tight with a rubber band
and also holds a scalpel blade at the center line so that when the cookie
rotates, the blade scores part way through the cookie cream.
After freezing, the cream becomes more brittle and is subject
to the crack propagation necessary to shear apart the two halves.
Ian also shows a bunch of ways he tried splitting
the cookies that didn't work out but are interesting nevertheless,
including a vacuum chamber and a homemade waterjet cutter.
More Projects.
Emily the engineer, has a new video on her YouTube channel
about 3D printing a pair of Heelys wheeled sneakers.
The video follows her design process to 3D print an entire shoe
with a captive wheel in the heel.
And while the result looks less
comfortable and less safe than a pair of standard roller skates,
It's super fun to come along on Emily's journey.
Also on YouTube, Handy Bear shows us how to create a totally
convincing, realistic brick wall miniature from a simple piece of foam.
We see the brick pattern itself come to life, as well as the requisite
distressing textures and final paint job that make it look super real.
Check it out.
This week, it was hard to miss the epic Table Collab
eight years in the Making by Bob Claggett, David Piccuito and Jimmy Diresta.
It's a three piece table where each of them made one segment.
Bob made a plinko style game out of his third.
David did some gorgeous walnut inlay, and Jimmy cast
resin with a repurposed wrench for a leg.
On her channel, Blondie Hacks, Quinn made a set of glass drip oilers for her steam engine.
She starts out by cutting some glass test tubes, then machines,
the brass caps and other parts that make up the gravity Fed oilers.
Not only are Quin's videos full of hypnotic machining closeups,
but she explains her process so thoroughly along the way.
Nick Poole does a deep dove on high vacuum technology
and shares his progress, experimenting with making his own electron tubes.
He's hoping to bring one of his vacuum
creations to Hackaday Supercon in November.
Frank Howarth made some turned wood segmented spheres and created
a very detailed video about the process in his signature multi self style.
I really like how these turned out and found the details of putting it together fascinating.
On Hackaday, I spotted Garrett Morrison's Click Wheel organ, a musical instrument
that works on the same principle as a card in your bike spokes.
The number of teeth on the wheels determine the pitch of the audio,
and Garrett did a bit of computing to determine a starting count
that would also support the other notes needed to fill out the octave.
JBV Creative has a new kinetic sculpture called Love at First Swipe,
where the two halves of a heart
join together when the operator swipes a finger across the base.
He goes into detail about the design and prototyping process
in a new video on his YouTube channel.
On the Kids Invent Stuff Channel,
Ruth and Shawn build ten year old Noah's hair washing hat,
including inlets for water, shampoo, spinning brushes and hot air for drying.
As usual, hilarity ensues as the duo attempt
to bring to life a child's invention sketch.
And now for some tools and tips.
The Simple Electronics Channel has an excellent guide to WLED,
A swell bit of software for controlling addressable LED strip wirelessly
with an ESP-32 or ESP-8266.
Cristiana on her channel
Get Hands Dirty shares her design process for creating a custom media console.
She goes over the factors that inform the design.
Then all the steps in between the vague project idea
and the complete 3D model and materials list.
This is a super helpful video for anyone who wants to level up their custom builds.
And if you've ever
wanted to make custom closet built-ins but weren't sure where to start,
Anika’s DIY Life has a video that will give you confidence to try it out.
She uses plywood to build custom shelves and drawers suited to her kids’ closets needs.
Seems like you could apply the same technique to build workshop storage too.
Speaking of workshops, it seems like everybody who's
anybody has a workshop, video or series out lately.
Check out Paul Jackman's Barn Workshop Build Out taking place
over the course of two years and Johnny Brooks Workshop Renovation
Series currently on Episode nine.
This week's Digi-Key Spotlight is my new Beginner Electronics series.
The first episode is all about LEDs, what the different kinds look like,
how they work, and the info you need to get started making your own LED circuits.
Give it a watch and let me know what you think.
And that's it for this week's show.
