We’ve seen 3D-printed houses before, but most make use of prefabricated chunks. This hurricane and tornado resistant hotel suite in the Philippines was printed in one shot.
Sound familiar? This is the work of [Andrey Rudenko], who started by building a concrete 3D printer in his garage 2 years ago, moved on to 3D printing his kids a concrete castle in his backyard later that year and now appears to have a full-blown company offering commercial 3D printed houses. Way to go [Andrey]!
The building was designed in Sketchup no less, and the printer makes use of Pronterface for the control software. It’s absolutely fascinating to see this built at full-scale. We want one. Continue reading “3D Printing Houses from Concrete”
Okay, now we’ve seen it all. Someone put the effort in to port Flappy Bird… to run on an e-cigarette. An eVic-VTC Mini to be precise. So now, between puffs, you can play one of the most frustrating games ever.
The SDK for the e-cig is available on GitHub, which was provided by a group of Redditors last year. If you’re interested in the game, and happen to have this model of e-cig, [Bank] has provided download and flashing instructions in the description of the YouTube video.
As one Reddit user points out:
“Your scientists were so preoccupied with whether or not they could, they didn’t stop to think if they should.”
To which the creator, [Balázs Bank], responded with the download links to install it yourself. Has science gone too far?

Sometimes it feels like we haven’t yet tapped into all the possibilities of additive manufacturing. Festo, a company that loves to try innovative things (and not always bring them to market), just came up with something called the 3D Cocooner — essentially, a rostock style 3D printer on its side, with a UV cure feature to allow it to build up skeletal structures and lattice style shapes.
Similar to the MX3D-Metal 3D printer (which is currently on a mission to build a bridge end-to-end — by itself), this 3D printer specializes in printing structures as opposed to the more traditional layer approach. It’s called the 3D Cocooner as it is a bionic technology platform designed to “spin” complex lattices, very similar to naturally occurring structures.
The cool thing is, it’s not actually using plastic filament like most printers — it’s actually printing using string! The string is covered with a special UV resin which is then hardened into place as soon as it is expelled from the print head — making this more like a giant robot spider than a 3D printer.

If you do a lot of one-off parts on your CNC machine you’ll know setup is the worst part of the process. Usually you’re using scrap material, you have to figure out how you’re going to clamp it, make sure the the piece is big enough to use, etc etc. Wouldn’t it be nice to just throw the material on the bed and start machining? Well, with a vacuum table as nice as this, you pretty much can!
[Jack Black] has an awesome CNC machine. As he’s been expanding his prototyping abilities, he decided he needed a better way of securing work pieces for machining, so he machined a two-piece aluminum vacuum table.

After scoring a non-functioning Gameboy in mint condition for $10, [Chad] decided it was time for a fun electronics project, so he ordered an LCD and bought a Pi Zero.
He started with a 3.5″ LCD off eBay for about $25, and got it running with the Pi Zero. It’s only 320×240 resolution, but hey, we’re recreating a Gameboy — not a smartphone. The next step was rather finicky: cutting up the case to fit the new components in.
Using a collection of files he whittled down the screen opening in the case to make room for the LCD, a few hours later and it looked surprisingly good.
From there he started laying out the components inside of the case, trying to figure out the best layout for everything to fit nicely. To power the unit he’s using a lithium ion battery from a Samsung Note which should give him some serious play-time. It fits right in where the game card is suppose to go.
To add some extra control functionality he’s added the game-pad buttons from a SNES onto the back where the battery door is, he’s also got a USB port on the side, a MicroSD card slot, and even a new audio pre-amp with potentiometer for controlling the speaker volume.
In case you can’t find a mint condition Gameboy case like [Chad] did, you could just print one from scratch

The more tools you have the better. Unfortunately, not everyone has the space, or the money for full-size equipment. Looking to expand his maker capabilities, [Bruno] had the clever idea to turn a hand-tool, into a power tool. One we’ve never even seen before — a powered hacksaw.
Using his 3D printer he designed a linkage system, not unlike a steam locomotive drive to turn rotary motion from a geared motor into linear motion. Not only that, it also angles the hacksaw as it goes. 3D printed brackets hold the hacksaw in place, and weight can be added to the top to adjust the cutting speed. He even 3D printed a guide for his vice to line up the material to where the blade will cut.
It’s a bit slow, but it’s fantastic at making cuts! Continue reading “3D Printed Linkage Produces Automatic Hacksaw!”
Aiming to improve the image quality of the photos on his website, [Jean] needed an external flash unit.
Say what you will about disposable cameras, but the fact that they were mass-produced, and are now nearly obsolete, means they are an absolute treasure trove of electronics components when you can buy them for dirt cheap. So [Jean] decided to turn a few of his disposable cameras into an external flash system for his DSLR (Translated).
He started by taking apart a Kodak digital camera and examining the circuit board. KEY1 enables the charging of the capacitor (the camera ON switch) and SW1 is located under the shutter-release.
Now all he had to do was replace SW1 with an electronic trigger from his DSLR.
