Domesticating Plasma With A Gorgeous Live Edge Table

If you’ve been reading Hackaday for any length of time, you’ll know we don’t often cover woodworking projects here. It’s not because we aren’t impressed with the skill and effort that folks put into them, and truth be told, we occasionally we even feel a pang of envy when looking at the final result. It’s just that, you know…they’re made of wood.

But when [Jay Bowles] of Plasma Channel sent in this live edge wooden table that features not only a pair of custom-made neon tubes but the burned out transistors and ICs from his previous high-voltage exploits — we knew this wasn’t exactly your grandpa’s idea of woodworking. In fact, he wisely offloaded a lot of the dead tree cutting and shaping to the burly gentlemen at the local sawmill so he could better focus his efforts on the sparky bits.

At its core, he’s created what’s generally known as a “river table” — a surface made of two or more pieces of live edge wood (that is, a piece of lumber that features at least one uncut edge) that are linked via a band of colored epoxy which looks like flowing water. It’s not uncommon to embed stones or even fake fish in the epoxy to really sell the underwater effect, but this is Plasma Channel we’re talking about, so [Jay] had other ideas.

The first step was hitting up a local neon supplier who could fabricate a pair of neon tubes which roughly followed the shape of his epoxy river. While he was waiting for them to be finished, [Jay] played around with a clever experimental rig that let him determine how thick he could pour the epoxy over the tubes before he lost the capacitive coupling effect he was going for. By embedding a short length of neon tube off-center in a block of epoxy, he could see how the thickness impacted his ability to manipulate the plasma with a wave of his hand just by flipping it over.

With the tube placed on clear standoffs, he was able to position it at the ideal depth for the final epoxy pours. It was around this time that he scattered the remains of his previous projects on the “bottom” of the river, so they can spend the rest of their days looking up at his latest technical triumph. We’re not sure if this is to punish the fallen silicon for giving up early or to honor their sacrifice in the name of progress, but in either event, we respect anyone who keeps a jar of blown components laying around for ritualistic applications.

Once the table was assembled, all that was left was to power the thing. Given his previous projects, [Jay] had no shortage of existing HV supplies to try out. But not being satisfied with anything in the back catalog, he ended up building a new supply that manages to pump out the required amount of juice while remaining silent (to human ears, at least). The unit is powered by a battery pack cleverly embedded into the legs of the table, and is easy to fiddle with thanks to a pulse-width modulation (PWM) module wired hooked to the input. All the components were then held in place with a wide array of custom brackets courtesy of his newly arrived 3D printer.

There’s a lot to love about this project, and more than a few lessons learned. Whether you’re interested in recreating the Tron-like effect of the neon tubes, or have been contemplating your own epoxy-pour worktable and want to see how a first-timer tackles it, this video is a great resource.

You Can Now Bootstrap Your Amiga Without A Floppy With This One Weird Trick

Traditionally, most Amigas were intended to boot from a floppy disk. . An Amiga can readily make its own boot floppy, but only once it’s already booted up. If you don’t have a floppy ready to go, you’re out of luck, as PCs can’t readily make them for Amigas. [Roc] whipped up the amigaXfer bootstrapping method to solve this very problem.

Shorting a couple of pins together can unlock a serial debug mode that can be used for bootstrapping the machine.

Available on Github, the amigaXfer tool is able to perform several tasks with an Amiga via its serial port. The Amiga must first be turned on while plugged into another computer running amigaXfer via serial connection. When the Workbench floppy prompt comes up, the CrashEntry feature on amigaXfer should be triggered, and the BERR and GND pins on the Amiga’s 68000 CPU should be connected just for a split second, triggering the Amiga to go into a special serial debug mode. This enables amigaXfer to take control, allowing a disk to be formatted and written with a debug bootblock, and this disk can then be used to boot the Amiga without the need for the hack.

It’s a nifty way to get your Amiga up and running if you’ve just bought it off eBay and it didn’t come with any disks. From here, you can use amigaXfer to load other programs onto the Amiga via the same serial cable you used for the bootstrapping process, too. The hack isn’t limited to just the Amiga 500, either. It should work on a range of machines, including AmigaOS versions 1.x, 2.x, and 3.x.

Unlike the Commodore 64, we probably won’t see brand new replica Amigas anytime soon, but we can dream. As always, if you’ve got ’em, send your hottest Amiga projects into the tipsline!

This Custom Workbench Will Make You Flip

In a recent video, [SomeSkillStudio] created a tidy tool storage system for their slim garage workbench. We have seen the “five knuckle” 270 degree hinges used here before and knew they’d enable some cool hacks. Here you’ll see how he puts this unique type of hardware to work building a densely packed work surface. For anyone who’s set up shop in a garage that’s somehow also supposed to still regularly host vehicles, you’ll know how important it is to have a place to put everything away and make it easy to do so.

The video has several great tips on making sure everything fits together, something key for anyone reproducing this with their own tool collection. If you have even less space, we have some great past workshop builds from portable, to tiny, to elaborate. Even if you’ve already established a place to work, we have tips on organizing your shop, giving each tool a home in a shadow board or across an infinite grid. Clearly, making a work space is one of our favorite kinds of projects.

How To Optimize Your Workspace: Analyze How You Work

[Jay Carlson] has shared some fantastic guidance on how to optimize one’s home workspace, and you just might want to emulate some of his layout, especially if you routinely juggle multiple projects. He makes the important point that different people have different needs, so one size does not fit all. Optimizing one’s workspace must first take into account what kind(s) of work one does, and many of his tips and tricks are pretty broadly applicable.

A rack of trays, each with a project
Looking online for these? A common industry term is “bun rack”. This one is “half-height” in size.

[Jay] works on embedded systems, and often switches between many different jobs and projects. Get your notepads ready, because there are plenty of great takeaways.

For example, to get a good top-down camera view of what’s on the workbench, he uses a camera mounted on an articulated arm (the kind that usually has a lamp attached to the end.) This makes the camera easy to deploy and easy to stow, and he can effortlessly save footage or share video with colleagues online.

Another great tip is using what most of us would call cafeteria trays and a matching rack. With each tray devoted to a different project or version of hardware, it makes switching between jobs as simple as sliding in one tray and pulling out another. It’s also a highly space-efficient way to store a lot of in-progress hardware. [Jay] gives a detailed walkthrough of his workspace and explains every decision, it’s well worth a read.

It’s always better to save space, as long as doing so doesn’t negatively impact the work itself. If you’re looking for space-saving tips, be sure to check out this tiny workshop’s space-saving hacks for more ideas.

Taking A Close Look At Hawkeye’s Workbench

We don’t have to tell you that the representation hackers and makers get in popular media is usually pretty poor. At this point, we’ve all come to accept that Hollywood is only interested in perpetuating negative stereotypes about hackers. But in scenes where the plot calls for a character to be working on an electronic device, it often seems like the prop department just sticks a soldering iron in the actor’s hand and calls it a day.

Of course, there are some exceptions. In the final episode of Marvel’s Hawkeye, the titular character is shown building some custom gear in a work area that looks suspiciously like somewhere actual work might get done. The set design was impressive enough that [Giovanni Bernardo] decided to pause the show and try to identify some of the tools and gadgets that litter the character’s refreshingly chaotic bench.

Now to be clear, we haven’t personally seen the latest Marvel spectacle from the House of Mouse, and it’s entirely possible that the illusion falls apart when taken as a whole. But from what we’re seeing here, it certainly looks like whoever did the set dressing for Hawkeye seems to have made an effort to recreate the hackerspace chic. We’ve got a multimeter within arm’s reach, the classic magnifying glass third arm, a Wiha screwdriver about to roll out of frame, and even some JB-Weld. If this looks eerily like what’s currently on your own bench, don’t worry, you’re not alone.

On the wider shot, we can see that the attention to detail wasn’t limited to the close-up. From the tools hanging on the pegboard to the shelves filled with rows of neatly labeled bins, we totally buy this as a functional workspace. It’s quite a bit neater than where we currently do our tinkering, but that’s more of a personal problem than anything. As we’ve seen, there are certainly people in this community who take their organization seriously.

Portrayals of science or technology in the media often leave a lot to be desired, which is why it’s so important to praise productions that put in the effort to get things right. With a little luck, maybe it will get through to the right people and raise the bar a bit. But even if it doesn’t change anything, we can at least give the folks behind the scenes some well-deserved recognition.

Workshop Organization With Panels

Tired of all your completed (or half-completed) projects cluttering up your workspace? Or you toss them in a box and later forget which box? Well [Another Maker] aka [Develop With Dan] came up with a solution which he dubs Mission Control — panelize your projects and store them in one of many cubbyholes which are provided by a false wall.

Back view of an example project panel

Each project gets a panel and is neatly stored away when not in use. For some project, this could be simply for storage. For other projects, this might serve as a showcase. Occupying the center of Mission Control is a large monitor, presumably a permanent installation. It looks like there are two different sizes of panels, but we wonder whether more and smaller panels might be more useful. As he’s putting this together, we particularly like one piece of advice that [Dan] offers regarding his custom tool, the Cornerator 3000:

Never hesitate to make a jig when you want to repeat something.

[Dan] will be posting this workspace on his GitHub repository along with code and documentation for various projects he posts on YouTube. He’s also proud to have built this system out of 100% recycled material, or as he says, he went dumpster diving. Do you have a good system for storing / displaying projects in your lab? Let us know in the comments below.

Workshop Tools Are Available In First-Class

Most of dream of having a fully-stocked shop with all of the tools needed to build our projects, at least if we don’t already have such a shop. In the meantime, a lot of us are hacking together our own tools and working on whatever bench space might be available to us. While [Emiel] aka [The Practical Engineer] has an envious shop to work from, his latest project goes to show how repurposing some aircraft-grade equipment can result in a high-quality toolbox for himself, without shelling out for any consumer-level solution. (Video, embedded below.)

The core of his workshop cart build is actually a recycled food service cart from an airline. While the original probably only housed some soft drinks and ice, this one has been kitted out to be much more functional. Since [Emiel] is using this to wheel around his machine shop, he used a CNC machine to cut out slots in black MDF sheets which would hold his drill bits, taps, and other tools. Working with MDF on a CNC machine turned out to not be as simple as he thought, since the MDF would separate and break away unless the CNC tool heads were operated in a specific way.

The build also includes several buckets for other tools, and a custom enclosure for the top of the cart specifically built for his machine tools’ tools to sit while he is working. It’s certainly a more cost-effective solution to a wheeled shop toolbox than buying something off-the-shelf, and a clever repurposing of something which would have otherwise ended up in a landfill. [Emiel] is no stranger to building any tools that he might need, including this custom belt sander built completely from the ground up.
