Recycled Piano Becomes Upcycled Workbench

Pianos are free, in case you’re not hip to the exciting world of musical instrument salvage. Yes, the home piano, once the pinnacle of upper middle class appreciation of the arts, is no longer. The piano your great aunt bought in 1963 is just taking up space, and it’s not like the guy on Craigslist giving away a free piano has a Bösendorfer.

It’s out of this reality of a surplus of cheap used pianos that [luke] built a new desk. He got it a while ago, but after getting it into his house, he realized it was too old to be tuned anymore. Or at least it was uneconomical to do so. This piano became a workbench, but after a while [luke] wanted something with a little more storage.

The process of converting this piano to a desk began with taking a few photos and putting them into Fusion 360. A series of panels and brackets were modeled in box jointed plywood, and the entire thing was cut out of 6mm Baltic birch plywood at the Vancouver Hack Space.

There are a few nice features that make this desk a little better than an Ikea special. There’s a Raspberry Pi mounted to the shelves, because the Pi still makes a great workbench computer. There’s a power supply, and hookups for 12 V, 5 V, and 3.3 V from an ATX power supply. This is controlled with an awesome antique power switch mounted to the side of the piano. Slap a few coats of black paint on that, and [luke] has an awesome, functional workbench that also has out-of-tune sympathetic strings. Not bad.

You can check out the entire build video below. Thanks [Jarrett] for sending this one in.

From Plastic Bottle To Plastic Brush

We first saw someone turn a plastic bottle into plastic ribbon about four years ago. Since then, we’ve wondered what this abundant, sturdy material could be used for besides just tying things together.

[Waldemar Sha] has answered that question with his excellent brush made from scrap wood and plastic bottle rope. Turning seven 1-litre bottles into curly bristle fodder was easy enough, but they have to be straight to brush effectively. No problem for [Waldemar]. He wound it all up on a  spinning homemade jig that’s anchored in a bench vise. The jig is designed to slide into a small electric sandwich grill he had lying around, and he just flips it after a while so the rope straightens evenly.

We really like the way he secured the bristles into the brush base. After drilling the holes, he sawed lengthwise channels that are deep enough for a bamboo skewer. Each group of bristles is hung over the skewer and down through the hole, and everything is glued in place before the handle is added. Sweep past the break to watch him tidy his workbench, and then learn how to make your own plastic rope.

Is there a better use of recycled plastic than making tools? Check out this joiner’s mallet made from milk jugs. Continue reading “From Plastic Bottle To Plastic Brush”

Business On The Outside, Electronics Workstation On The Inside

As an electrical engineering student, [Brandon Rice] had the full suite of electronics tools you’d expect. Cramming them all into a dorm room was doable — but cramped — a labour to square everything away from his desk’s top when he had to work on something else. To make it easier on himself, he built himself a portable electronics workstation inside the dimensions of a briefcase.

Built from scratch, the workstation includes a list of features that should have you salivating by the end. Instead of messing with a bunch of cables, on-board power is supplied by a dismantled 24V, 6A power brick, using a buck converter and ATmega to regulate and display the voltage, with power running directly to  12V and 5V lines of a breadboard in the middle of the workstation. A wealth of components are stored in two dozen 3d printed 1″ capsules setting them in loops pinned to the lid.

If all this was not already enough, there’s more!

Hackaday Links: December 17, 2017

Where do you go if you want crazy old electronic crap? If you’re thinking a ham swap meet is the best place, think again. [Fran] got the opportunity to clean out the storage closet for the physics department at the University of Pennsylvania. Oh, man is there some cool stuff here. This room was filled to the brim with old databooks and development boards, and a sample kit for the unobtanium Nimo tube.

The Gigatron is a Hackaday Prize entry to build a multi-Megahertz computer with a color display out of TTL logic. Now, all this work is finally paying off. [Marcel] has turned the Gigatron into a kit. Save for the memories, this computer is pretty much entirely 74-series logic implemented on a gigantic board. Someone is writing a chess program for it. It’s huge, awesome, and the kits should cost under $200.

What’s cooler than BattleBots, and also isn’t Junkyard Wars? BattleBots, but in drone form. Drone Clash was originally announced in March, but now they’re moving it up to February to coincide with the TUS Expo. What could be better than flaming piles of lithium?

The Atari Lynx went down in history as the first portable console with a color LCD. There was a problem with the Lynx; the display was absolutely terrible. [RetroManCave] found someone selling an LCD upgrade kit for the Lynx, and the results are extremely impressive. The colors aren’t washed out, and since the backlight isn’t a fluorescent light bulb (yes, really), this Lynx should get a bit more run time for each set of batteries.

Like dead tree carcasses? You need to butcher some dead tree carcasses. The best way to do this is on a proper workbench, and [Paul Sellers] is working on a video series on how to make a workbench. He’s up to episode 3, where the legs are mortised. This is all done with hand tools, and the videos are far more interesting than you would think.

If you need some very small, very blinky wearables, here’s an option. This build is literally three parts — an LED matrix, an ATtiny2313, and a coin cell battery. Seems like this could be an entry for the Coin Cell Challenge we have going on right now.

Tricked-Out Tablet Becomes Workbench Tool

The workbench of the typical electronics hobbyist today would probably be largely recognizable by Heathkit builders back in the 60s and 70s. But where the techs and tinkerers of yesteryear would have had a real dead-tree SAMS Photofact schematic spread out on the bench, today you’ll get more use out of a flat-screen display for data sheets and schematics, and this handy shop Frankentablet might be just the thing to build.

Tablets like the older Nexus 9 that [enginoor] used as the basis for this build have a little bit of a form-factor problem because unlike a laptop, a tablet isn’t very good at standing up on its own. To fix that, they found a suitable silicone skin for the Nexus, and with some silicone adhesive began bedazzling the back of the tablet. A bendy tripod intended for phones was added, and with the tablet able to stand on its own they maximized the USB port with a right angle adapter and a hub. Now the tablet has a USB drive, a mouse, and a keyboard, ready for perusing data sheets online. And hackers of a certain age will appreciate the eyeball-enhancing potential of the attached USB microscope.

[enginoor]’s bench tablet is great, but we’ve seen full-fledged bench PCs before too. Take your pick — wall mounted and floating, or built right into the workbench.

Thanks to [ccvi] for the tip.

The Most Useless Tools You Can’t Seem To Part With

I’m a tool person. No matter how hard I try, I eventually end up with a bunch of tools that I just can’t bear to banish from my workshop. Why? I’m gonna keep it 100%: it’s the same emotion behind hoarding — fearing that you might need a thing later and not be able to have it.

The stuff costs money, and if you have to script to buy a bunch of tools pertaining to Project X, you expect to still have and probably need those very same tools — even if they have to sit in a box on my shelf for 20 years, taunting me every time I have to move it to one side.  “Heat-bending element” the box’s label describes at tool I haven’t used in at least 5 years. I have a bunch of these white elephants. I’ll probably need to heat-bend acrylic real soon… yeah.

I’ve found that pretty much everyone in our crowd can relate. You buy a special tool for one project and it was expensive and tremendously helpful, and since then it’s been sitting around uselessly. You certainly couldn’t part with it, what if you needed it again? So you store it in your house for 20 years, occasionally coming across it when looking for something else, but it never actually gets used.

Join me now in a walk down our memory lane of useless tools.

It’s A Wall-Mounted Dremel Workstation!

We’ve all seen Dremel drill presses, but [Tuomas Soikkeli] has created a full-fledged (albeit miniature) workstation using his Dremel as the motor. He has a gnome-sized belt sander with what appear to be skateboard wheels turning the belt, with the Dremel’s toolhead tensioning the belt and turning it as well. There’s a wee table saw, petite lathe, cute router, etc.

The Dremel attaches to the base via the 3/4-to-1/2 threaded end upon which specialized tool ends may be connected, and which DIY add-ons (like this light ring that we published previously) typical connect. Though in truth the threaded end varies in tensile strength from model to model — even the knockoffs have the same end, but is it strong enough to attach to the rig?

We like how [Tuomas] has his rig mounted to the wall. It looks like he has a couple of flexible shaft extenders nearby, allowing the rig to almost serve same role as a shop’s air tools.
