Hack A Day member CF made this sweet electronic wristwatch using the incredibly small and affordable ATmega328 chip. The LiquidWatch uses 97 LEDs to tell the time. The inner ring of LEDs shows the hour, while the outer ring shows the minutes and seconds.
Kiwamijapan loves to make DIY weapons and tools. But this one takes the cake. He took katsuobushi – dried and preserved tuna (aka bonito) – which is literally hard as a rock, and turned it into a knife. Get ready for a whole lot of soothing sharpening and filing sounds.
Artist and goofball Bobby Duke laminates together a few hunk of bass wood and carves them into the shape of a mug. But his craft project doesn’t end there, as he eventually transforms his creation into an awesome sculpture with the help of some colored pencils.
Prop maker David Guyton takes a break from making badass prop armor to present his take on a retractable license plate. His DIY solution is made from affordable materials and uses a simple scissor mechanism. You’ll have to figure out how to mount it on your car though.
Want to make a dessert that’s sure to be the talk of the party? Ann Reardon of How to Cook That shows us how to create a tasty salted caramel and chocolate cake that looks like a pot overflowing with popcorn. She makes it look easy, but we’re sure it’s not. Full recipe here.
Maker W&M walks us through the process of turning a couple of muffin tins into a miniature concrete mixer, complete with a motorized stirrer. Though in this case, its purpose is to smoothly blend instant coffee with water. Probably would make a good hot cocoa too.
LEGO master Sariel believes Santa Claus knows about climate change. So he made St. Nick an amphibious sleigh with the help of a thematic part – LEGO Christmas baubles. They’re not completely airtight, but they work well enough as wheels both on ground and in water.
Knives are typically made from tool steel. But the guys at Ollari’s show us how with the proper cutting blades and an angle grinder, a block of granite can be transformed into a sharp-edged cutting tool as well. We’re betting Primitive Technology would do the same with only a rock.
While so much of the focus has been on BB-8 in recent years, R2-D2 is still our favorite droid. Now you can build your own 12″ tall R2 unit using this DIY kit which includes all the parts you need, and stickers for customizing your bot. Great for kids or kids at heart.
Make: author Caleb Kraft came across this nifty plaything by Mike’s Electric Stuff, which uses sensors and a cylindrical grid of LEDs that simulate falling snow or sand as it’s flipped end-over-end. Mike needs to turn this thing into a toy you can buy. He’d sell thousands.
Colin Furze continues what he started. After last year’s life-size AT-ACT, the mad inventor once again scoured eBay for parts to build a life-size model of a Star Wars vehicle. This time it’s Kylo Ren’s ride, the TIE Silencer. The model is on display at Burghley House until 12/10/17.
Adafruit Industries shares a relatively simple, yet very cool project – a wand which displays a persistence of vision illusion when waved in the air. Naturally, the build uses parts from Adafruit, including DotStar LEDs, and a Feather controller board. Tutorial, files, and code here.
Got a broken washing machine and some woodworking skills? Then check out Scrap Wood City’s clip in which he shows how to convert the metal tub from a washing machine into the body for a fretless acoustic contrabass. It’s only got two strings, but it still sounds cool.
Bob Clagett of I Like to Make Stuff admittedly isn’t a weapon-making expert, but he sure knows his way around a bandsaw. In this clip, he shows us how he used some scraps of hardwood flooring to create a wooden practice katana with some very impressive results.
Primitive Technology hit the proverbial reset button on his live-action Stone Age role-playing game. He’s starting on a new and different map – a tropical rainforest with a permanent creek. We like to think he bartered for it with cargo shorts and cameras.
Buttered Side Down has been really wishing he had super powers, so he decided to try and give himself some abilities using ordinary kitchen appliances, a fax machine, and stuff he had lying around the house. It’s clear that his VFX skills far exceed his superhero skills.
Lowe’s challenged four trade professionals and makers – an electrician, a home remodeler and YouTubers Grant Thompson and Bob Clagett – to get through an escape room that challenged their DIY skills. Is it one long Lowe’s ad? Yep. But it’s legitimately entertaining too.
A few days ago, Peter Sripol shared a video of him doing short hops on his homemade electric airplane. It was a sight to behold but technically… that wasn’t flying. This is. Peter got better batteries and finally gave the people what they want. Amazing stuff.
MadGyver shows off a fun little project – an Arduino-based glove which can detect gestures, and uses the inputs to control the speed of a strobe light, which when aimed a moving object makes it look like it controls the speed and direction of time. Build details on Instructables.
Flight fanatic Peter Sripol has built his share of small, unmanned flying machines, but he’s now turned his attention to something a bit bigger, building himself a single-seat aircraft powered by electric motors, and airworthy enough that he was willing to be its test pilot.
