Organizational Inspiration From The Discount Tool Company

October 15, 2022 by 13 Comments

When in need of any tool to get a job done quickly, or only for a small number of times, it’s great to have a local “discount tool” company locally for some working, yet often low-quality solution to whatever problem might arise. While there are some gems, most of these tools won’t last through heavy, sustained use like their more expensive counterparts will. On the other hand, there are other things to be had at these discount shops, such as inspiration for tackling a storage problem.

This particular storage system comes from Harbor Freight, and uses a set linked crosshairs, the center of which is hollowed out. A set of movable compartments sits on top with feet that can interlock inside the crosshairs. This allows much more efficient use of space within the toolboxes, but [Alan] wanted it to be useful for more that that. He designed and implemented the Storage Case Base Template (SCBT) which allows for a container of any size to be fitted with a similar crosshair network.

With this non-proprietary system implemented and printed, the original goal of reducing the clutter in [Alan]’s workspace was accomplished. The 3D printing files can be modified easily for any space, and are available both on Thingiverse and Printables. For some other ways of packing a lot into a small space, we featured this tiny workshop a while back that’s packed with storage hacks.

No Tool Left Behind With The Help Of Homemade Shadow Boards

June 21, 2022 by 38 Comments

Shadowed tool storage — where a tool outline shows at a glance what’s missing from storage — is a really smart way to keep your shop neat. They’re also super important for cases where a tool left behind could be a tragedy. Think, where’s-that-10-mm-socket-while-working-on-a-jet-engine? important. (It’s always the 10-mm socket.)

But just because shadow boards are smart, doesn’t mean they’re easy to make. That’s why [Scott Prince] came up with this semi-automated method for making toolbox shadow boards. The job of tracing around each tool on some sort of suitable material and cutting out the shapes seems straightforward, but the trick comes in organizing the outlines given the space available and the particular collection of tools.

[Scott]’s method starts with capturing images of each individual tool. He used a PiCam and a lightbox housed, strangely enough, in a storage bench; we’d love to hear the full story behind that, but pretty much any digital camera would do for the job. After compensating for distortion with OpenCV, cropping the images, and turning the image into a vector outline of the tool, [Scott] was left with the task of putting the tools into logical groups and laying them out sensibly. After tweaking the tool outlines and adding finger cutouts for easy pickup, [Scott] put his CNC router to work. He chose to use a high-density polyethylene product made by his employer, which looks fantastic, but MDF would work fine too.

We have to admit to a fair degree of toolbox envy now that we’ve seen what shadow boards can do. We’re a bit torn, though — [Zach Friedman]’s Gridfinity storage system has a lot going for it, too.

Helium Recovery System Saves Costs

June 13, 2022 by 31 Comments

Helium is the most common element in the universe besides hydrogen, but despite this universal abundance it is surprisingly difficult to come across on Earth. Part of the problem is that it is non-renewable, so unless it is specifically captured during mining its low density means that it simply escapes the atmosphere. For that reason [Meow] maintains a helium recovery system for a lab which is detailed in this build.

The purpose of the system is to supply a refrigerant to other projects in the lab. Liquid helium is around 4 Kelvin and is useful across a wide variety of lab tests, but it is extremely expensive to come across. [Meow]’s recovery system is given gaseous helium recovered from these tests, and the equipment turns it back into extremely cold liquid helium in a closed-cycle process. The post outlines the system as a whole plus goes over some troubleshooting that they recently had to do, and shows off a lot of the specialized tools needed as well.

Low-weight gasses like these can be particularly difficult to deal with as well because their small atomic size means they can escape fittings, plumbing, and equipment quite easily compared to other gasses. As a result, this equipment is very specialized and worth a look. For a less lab-based helium project, though, head on over to this helium-filled guitar instead.

Internal Combustion Torque Monster Has Great Impact

March 3, 2022 by 26 Comments

Once the domain of automotive repair shops and serious hobbyists with air compressors, the impact driver so famously used to remove and install wheel lug nuts and other Big Fasteners with just a squeeze of the trigger is more accessible than ever. Thanks to Lithium Ion batteries and powerful and compact brushless motors, you can now buy a reasonably powerful and torquey impact driver for a relatively low price- no air compressor needed! But what if you relish the thought of a noisy, unwieldy and unnecessarily loud torque monster? Then the video below the break by [Torque Test Channel] is just what you need!

Now, this is Hackaday, so we don’t have to go into detail about why a person might want to rip out the electric motor and adapt a 60cc 2 stroke engine in its place. Of course that’s the obvious choice. But [Torque Test Channel] isn’t just mucking about for the fun of it. No, they’re having their fun, experimenting with internal combustion engines in odd places before they are banned by 2024 in California. Now, we’re not sure if the ban includes these exact types of engines- but who needs details when you have an impact driver that can change semi tires like a NASCAR pit crew.

Looking like an overpowered weapon from a first person shoot’em up game, [Torque Test Channel]’s modified Milwaukee tests well after some modifications. Be sure to watch the video to see how it performs against an electric tool that’s even larger than itself. There are graphs, charts, and an explanation of what can be done to make even more power in the future. We’re looking forward to it!

What’s that you say? You don’t have a two stroke engine sitting around waiting to be swapped into ridiculous gadgets? Look no further than your local fridge compressor and be ready to burn some hours getting it running.

Pressure Gauge Built In A Vacuum

February 23, 2022 by 6 Comments

Necessity might be the mother of all invention, but we often find that inventions around here are just as often driven by expensive off-the-shelf parts and a lack of willingness to spend top dollar for them. More often than not, we find people building their own tools or parts as if these high prices are a challenge instead of simply shrugging and ordering them from a supplier. The latest in those accepting the challenge of building their own parts is [Advanced Tinkering] who needed a specialty pressure gauge for a vacuum chamber.

In this specific case, the sensor itself is not too highly priced but the controller for it was the deal-breaker, so with a trusty Arduino in hand a custom gauge was fashioned once the sensor was acquired. This one uses an external analog-to-digital converter to interface with the sensor with 16-bit resolution, along with some circuitry to bring the ~8 V output of the sensor down to the 5 V required by the microcontroller. [Advanced Tinkering] wanted a custom live readout as well, so a 3D printed enclosure was built that includes both an LCD readout of the pressure and a screen with a graph of the pressure over time.

For anyone else making sensitive pressure measurements in a vacuum chamber, [Advanced Tinkering] made the project code available on a GitHub page. It’s a great solution to an otherwise overpriced part provided you have the time to build something custom. If you’re looking for something a little less delicate, though, take a look at this no-battery pressure sensor meant to ride along on a bicycle wheel.

One Tool Twists Wires, And Skewers Shish Kebabs

February 11, 2022 by 19 Comments

Twisting stranded wire with your fingers in preparation for tinning and/or soldering is almost a reflex for folks making electronic assemblies. But what if the wires are too close to get your fingers around, or you have the fingers of a sumo wresters? Well [DIYDSP] has a solution for you (see video below the break) that’s easy to make from a shish kebab skewer that’s probably rolling around your kitchen drawer. The reason that [DIYDSP] wanted to twist such closely spaced wires was to solder a length of 0.1 in O.C. stranded ribbon cable directly onto a PCB pin header pattern.

The method is very simple. Drill a long hole in the factory-cut flat end, followed by using a countersink bit to give a conical taper to guide the wires in. [DIYDSP] found that a 1/16 inch (1.6 mm) drill bit was a bit too large to grip the types of wires he was using, and finally settled on a 0.6 mm bit. If you are using larger wires, you should experiment to get the right size, or just build a handful of these of differing diameters since they’re so easy to make — just mark them clearly so you don’t accidentally grill shish kebabs with them on the BBQ.

The resulting tool is not unlike the business end of a hand-held wire-wrap tool, but works different principle and is a fraction of the cost. If you do any amount of interconnect wiring with stranded wires, then you should check out this video and whip up a couple of these to throw in your tool box.

Building A Custom Branding Iron With Swappable Date Blocks

December 17, 2021 by 6 Comments

Branding can be done on wood with just about any old bit of hot metal, but if you want to do it well, properly-crafted tooling will go a long way. [Wesley Treat] has built just that with this modular branding iron design.

The branding tooling itself is machined out of brass on an X-Carve CNC router, using [Wesley]’s own logo. The part is sanded after machining to remove tooling marks. A smaller brass slug is then machined with the numerals for various years with which [Wesley] may wish to stamp his projects.

Rather than hacking something sloppy together, the iron itself is assembled with a beautifully wood-turned handle of his own creation and a steel backing plate to hold the tooling. The date is separately removable from the main logo itself for easy changes in future. Naturally, the tool graphics are done in reverse so as to register the right way around when burned onto wood.

The tool is used with a torch to heat the brass up such that it can leave its impression on wooden surfaces. The final results are solid, if not quite perfect; getting the temperature across the tool perfectly matched would be key to getting the cleanest results. An electric heating element running in closed loop could be a way to achieve this.

Fundamentally, it’s a tidy way to mark your wooden projects in a hurry. We’ve seen wood burning reach even greater heights, too, such as with this CNC pyrography machine. Video after the break.
