Telegraphs were once the fastest way to send messages over a distance. While they’re long since obsolete, DIYprojects decided to build a modern take on the paper strip telegraph, using an Arduino Mini, a motor, wood, and a pen to write down text messages. Build guide here.
Epoxy resin lets you cast just about any shape into a durable and rigid form. In this DIY clip from Dread CraftStation, he shows us how clear resin can be tinted, molded, and sanded to form a complete set of see-through chess pieces. The resulting set looks super slick when placed on a board with lighting underneath.
We’ve seen a number of tiny arcade machines, but what we really want someone to produce is a teensy digital pinball machine like this one from maker Matt “Circuitbeard” Brailsford. It uses a tiny Windows 10 computer called the LattePanda and runs Visual Pinball on its dual LCD screens. Build details here.
Gadgets from the 1980s were lots of fun, but the plastics they used back then had a tendency to yellow, and look awful over time. Watch in awe as Odd Tinkering takes a grubby old Nintendo Game Boy and makes it like new. That soldering iron trick to fix the lines on the screen is nifty.
Builder Jimmy Diresta wanted a new barbecue grill, but instead of running out to the nearest Costco to buy one, he decided to build his own. And Jimmy’s homebrew version has a really neat trick – scissor-style lifts, a crank, and a gear drive for adjusting its height from the flame.
Making things out of colored pencils seems to be a bit of a trend. There’s something about the colors and texture that make such things immensely appealing. Angqvist recently made himself a knife handle by laminating together a bunch of sliced up pencils, and it looks fantastic.
Willy Wonka and the Chocolate Factory includes a classic scene where his guests try out fruit-flavored lickable wallpaper. The guys at Hellthy Junk Food replicated the idea, but went one better by printing theirs on edible paper. Also, we’re never tasting snozzberries.
“I’m not a very good woodworker… so that’s why I have to introduce a stupid gimmick that makes people want to watch my video.” Yep, so that’s why I did a thing decided to carve himself a wooden spoon using a metal spoon as his only tool. And some sandpaper… and a furnace… and…
Currently available in the UK, U-Build is a DIY modular and flat-pack wood and hardware system for building structures, furniture, and storage. You design your layout and dimensions on its website, then the parts are sent to you. You need only basic tools to put the frame together.
Prop maker David Guyton made a replica of Iron Man’s Nano Gauntlet from Avengers: Endgame. Rather than cheap materials, he built it out of steel, brass, and glass. But he will upload a template on his website so you can make it out of different materials if you want.
Woodworker Carl Jacobsen made quite the mess in his shop for this experiment, in which he decided to turn a bowling ball on his lathe, chiseling away the ball’s outer surface and inner core to produce a surprisingly pleasing bowl. Carl says the biggest issue was the smell its core made.
Spectrum analyzers are a nifty way to visualize music. But maker Platinum Kit decided the displays that come with graphic equalizers were too small, so he built a jumbo version with colorful LEDs placed behind acrylic blocks. He reversed the lows and highs, but it’s still super cool.
Like many other makers, SKM loves to build things from cardboard. This time, he used what appears to be an off-the-shelf template to create a model of Iron Man’s iconic helmet, though this one is guaranteed to offer absolutely no level of protection to its wearer.
For no reason other than to see if he could do it, artist Nick Zammeti made a gigantic coloring pencil out of thousands of individual coloring pencils. He adhered the pencils together with resin, turned them on a lathe, then carved it into shape. Its giant lead means it can actually draw.
Colin Furze made an airsoft replica of the briefcase machine gun in Kingsman 2. It’s also remote-controlled, but the real trick was figuring out how to cock and trigger the gun with one switch. Believe it or not, there’s actually a lethal version of this setup from decades ago.
We’ve seen industrial machines that can bend wires into shapes, but thanks to 3D printing and low-cost controllers like Arduino, you can make your own desktop machine now. How to Mechatronics shows us exactly how. Grab the full instructions, models, code, and schematics here.
YouTube’s premiere mechanic ChrisFix shows us how to make a hidden kill switch for your vehicle. When switched on, it interrupts the flow of electricity to the vehicle’s fuel pump relay, preventing it from starting, even with a key. It takes a bit of fiddling, but it costs only $10 in parts.
