Salvaging an Ancient, Dangerous Machine With Wood

Posted on by

What do you do when you have a gigantic old drum sander with a bent table? Scrapping it will give you a few cents per pound, but this machine is just too cool, and would be too useful to just throw away. That’s when inspiration strikes. To fix this old machine, [Frank Howarth] built a new bed for an old drum sander out of wood.

The machine in question is a Frank H. Clement Surface Sanding Machine from the early part of the 20th century. This machine is basically a 30 inch long, 14 inch diameter drum that’s wrapped in …read more

Box Joint Jig Does Barcodes

Posted on by

Woodworking is the fine art of turning dead tree carcasses into precision instruments. That means breaking out the saws and chisels and making many, many precise cuts over and over. If you have a table saw, every problem becomes a piece of wood, or something like that, and we’ve seen some fantastic jigs that make these precision cuts even easier. We’ve never seen something like this, though. It’s a box joint jig for a table saw, it’s automated, and it puts barcodes on boxes.

[Ben] built this box joint jig a few years ago as a computer-controlled device that slowly …read more

This Dust Collector Will Blow You Away.

Posted on by

As [Marius Hornberger] was working in his woodshop, a thunderous bang suddenly rocked the space. A brief search revealed the blower for the dust collector had shifted several inches despite being stoutly fastened down. Turns out, the blower had blown itself up when one of the impeller fins came loose. Time to revise and build a bigger, better dust collector!

[Hornberger] is thorough in describing his process, the video series chronicles where he went astray in his original design and how he’s gone about improving on those elements. For instance, the original impeller had six fins which meant fewer points …read more

Medium Machine Mediates Microcontroller Messages

Posted on by

Connecting computers to human brains is currently limited to the scope of science fiction and a few cutting-edge laboratories. Tapping into some nerves farther from our central wetware is possible and [Peter Buczkowski] shows us his stylish machine for implanting a pattern into our brains without actively having to memorize anything.

His Medium Machine leverages a TENS unit to activate forearm muscles in a pattern programmed into an Arduino. Users place their forearm across two aluminum electrodes mounted on a tasteful wooden platform and extend a single finger over a button. Electrical impulses trigger the muscles which press the button. …read more

DIY Mini-Amp Goes to Eleven

Posted on by

On the day mini-amps were invented, electric guitar players the world over rejoiced.  No longer would they be house-bound when jamming out on their favourite guitar. It is a doubly wondrous day indeed when an electric guitar-inclined maker realizes they can make their own.

[Frank Olson Music] took apart an old pair of headphones and salvaged the speakers — perhaps intending to replicate a vintage sound — and set them aside. Relying on the incisive application of an X-Acto knife, [Olson] made swift work cutting some basswood planks into pieces of the amp before gluing them together — sizing it …read more

How to Test a B-52 Against EMP: Project ATLAS-I

Posted on by

Audacious times generate audacious efforts, especially when national pride and security are perceived to be at stake. Such was the case in the 1950s and 1960s, with the Space Race that started with a Russian sphere whizzing around the planet and ended with Neil Armstrong’s footprint on the Moon. But at the same time, other efforts were underway to answer big questions of national import, such as determining how durable the United States’ strategic assets were, and whether they could withstand the known effects of electromagnetic pulse (EMP), a high-intensity burst of electromagnetic energy that could potentially disable a plane …read more

Mechanical Wooden Turing Machine

Posted on by

Alan Turing theorized a machine that could do infinite calculations from an infinite amount of data that computes based on a set of rules. It starts with an input, transforms the data and outputs an answer. Computation at its simplest. The Turing machine is considered a blueprint for modern computers and has also become a blueprint for builders to challenge themselves for decades.

Inspired by watching The Imitation Game, a historical drama loosely based on Alan Turing, [Richard J. Ridel] researched Alan Turing and decided to build a Turing machine of his own. During his research, he found most machines …read more

The White Rabbit Nixie Clock

Posted on by

Instructables user [hellboy] — a recent convert to the ways of the laser cutter — is a longtime admirer of Nixie tubes. In melding these two joys, he has been able to design and build this gorgeous work of art: The White Rabbit Nixie Clock.

Going into this build, [hellboy] was concerned over the lifespan of the tubes, and so needed to be able to turn them off when not needed. Discarding their original idea of having the clock open with servos, [hellboy]’s clock opens by pressing down on a bar and is closed by snapping the lid shut — …read more

Need Strength? It’s Modified Wood You Want!

Posted on by

Wood is surely one of the most versatile materials available. It can be found in a huge variety of colours and physical properties depending on the variety of the tree that grew it, and it has been fashioned into all conceivable devices, products, and structures over millenia. It’s not without shortcomings though, and one of the most obvious is that it can’t match the strength of some other materials. To carry large forces with a piece of wood that piece has to be made much larger than a corresponding piece of steel, something which is not a problem in a …read more

Celebrating the Olympics With Flaming Windmills

Posted on by

Like many of us, [Gustav Evertsson] was looking for an excuse to set stuff on fire and spin it around really fast to see what would happen. Luckily for him (and us) the Winter Olympics have started, which ended up being the perfect guise for this particular experiment. With some motors from eBay and some flaming steel wool, he created a particularly terrifying version of the Olympic’s iconic linked rings logo. Even if you won’t be tuning in for the commercials Winter Games, you should at least set aside 6 minutes to watch this build video.

The beginning of the …read more
