Steam-Powered Machine Shop

August 19, 2015 by James Hobson 68 Comments

It’s sometimes hard to believe how stuff was made over a hundred years ago when electricity wasn’t widely available. One of the most common ways of powering tools was via belt drive — powered by a water mill, or a steam engine, or even horses. [David Richards] has spent a good chunk of time making his own period accurate steam powered machine shop — and it’s fantastic.

It represents approximately what a 1920’s machine shop would look like in America. Not a single tool is newer than 1925. The whole shop is powered by a line shaft using steam power. A massive boiler provides steam for a Pennsylvania built 5 by 5 steam engine, dating back to approximately 1895. Using belts and clutches, it powers a few lathes, drill presses, a mill, and even a shaper — an identical machine to one in the Edison Museum!

Literal Breadboard Hack Forces It To Accept Dual Pin Headers

August 18, 2015 by Al Williams 37 Comments

Usually when there is a clear demand for something, some entrepreneur will fill that demand. Unfortunately, no one seems to think there’s a need for a solderless breadboard product that can handle boards that have a dual row header. These devices have 0.1″ spacing in both directions, so while they will fit in a standard breadboard, the contacts will short out the adjacent pins on the device, which makes it worthless.

[Baz] needed to connect an RF24L01 module to a breadboard. Instead of connecting leads to the device or devising a breakout board, [Baz] actually hacked his breadboard. To make an area to plug in a dual row device, he took the breadboard apart, pulled the spring contacts, cut them, and then put them back in.

Of course, you have to make sure the cut is wide enough that the two parts of the spring won’t touch. It looks like [Baz] used a small screwdriver to help the springs keep their shape and cut them with simple diagonal cutters.

Woodworking Blemish Removal Technique Pops Your Clamping Dimples

August 18, 2015 by Sonya Vasquez 43 Comments

If you’ve done any woodworking in the past, odds are likely that you’ll eventually end up fixturing your stock in the crushing grip of a vise or C-Clamp. The results are painful, leaving a lasting impression of the clamp jaws on your beautiful, otherwise-unmarred piece of stock. Often, you’ll need to design around this issue, fixture it gently, or cushion the grip with a softer intermediate material. [Chimponabike] had other thoughts, though, and developed a technique for successfully popping the dimples out, returning clamped wood to its perfectly unmarred form.

The Technique itself is dead simple and takes only a few minutes to perform. Simply apply a small amount of water, let it seep into the wood, and then bring a hot iron down onto the soaked wood to evaporate off the soaked water–instantly inflating the wood back into its original form!

It’s not the first time we’ve abused our tools and home appliances to do some clever things with wood, but it’s certainly worth adding to that “Tome of Techniques: Wood Edition” that you’ve been building in your browser’s bookmarks bar.

Thanks for the tip, [James]!

Panel-Mounted Breadboard Accessories

August 14, 2015 by Al Williams 11 Comments

[Chuck Stephens] grew up with Radio Shack 100-in-1 electronic kits. The ones with lots of components and spring terminals that could be wired to be a radio, a burglar alarm, or whatever.[Chuck] graduated to solderless breadboard, but did miss having panel mounted components like pots and switches easily available. So he has been building his own accessory boxes.

Of course, it is easy enough to just connect breadboard wires to component, but [Chuck] went further than that. Using boxes of different types (including a cigar box), he mounted the components properly and also wired them to a breadboard for easy connection.

If you’ve ever tried to solder to breadboard springs (we have), you’ve found it is hard to get adhesion to the shiny metal. [Chuck] solved the problem by crimping little wire hooks to the springs. The result is a good looking and functional prototyping aid.

They do make tiny breadboard style contacts (called tie point blocks; good luck finding them) for this kind of application, but the crimp technique works on common breadboards. These are cheap and much easier to find.

Of course, these days, we are as likely to want to mount SMDs than panel mounted controls. Now if we could only figure out where to put the components. If you want something less involved, take a look at the video below.

3D Printed Vice Holds Dev Boards Beside Breadboard

August 14, 2015 by Bryan Cockfield 13 Comments

The Stickvise has been a staple of the Hackaday community for a while now. If you need something held for soldering there’s no better low-cost helping hand. But if you’re just using a breadboard and a dev board of some sort, there’s another vice on the horizon that uses similar spring clamping to hold everything in place while you build something awesome.

While [Pat]’s inspiration came from the aforementioned Stickvise, the new 3d-printed vice is just what you’ll need before you’re ready to do the soldering. The vice is spring-loaded using rubber bands. The base is sized to fit a standard breadboard in the center with clamping arms on either side to hold dev boards such as an Arduino. This innovative yet simple de”vice” grips boards well enough that you won’t be chasing them around your desk, knocking wires out of place, anymore.

There are some nuances to this board, so be sure to check out the video below to see it in action. As we mentioned, it uses rubber bands instead of springs to keep it simple, and it has some shapes that are easily 3d printed such as the triangular rails. If you want to 3d print your own, the files you’ll need are available on the project’s site. If you want to get even simpler, we’ve seen a few other vices around here as well.

The Stickvise is available for sale in the Hackaday Store.

Cardboard Aided Design Is The New CAD

August 9, 2015 by George Graves 50 Comments

The term “workflow” gets thrown around a lot these days. For example, say you own a 3D printer and you just came up with an idea. The temptation is to go straight to your favorite CAD tool, start designing the finished product, and then hit print. That, in many cases, can be the worst thing you could do. You would be missing out on all the variation and design choices you can easily try out with a simple series of drawings.

So, you’ve worked out your drawing, played with the design a bit, and now it is time to design in 3D on the computer right? Not so fast. Depending on the nature of the design, you might want to follow this nice tutorial from [Willy Nicholas] on how to quickly make a cardboard prototype.

Now, obviously this won’t work on all designs. But it’s a tool everyone should keep in their bag of tricks. It allows for basically free, quick mock ups that you can hold in your hand. That last bit is important, because having something you can touch and see is a huge part of the design process.

You can also use cardboard as an excellent device for making templates for working with materials such as sheet metal. In case you have seen it, check out “Project Binky” to see what a couple of blokes in England are able to accomplish with nothing much more than a welder, a grinder and some cardboard.

Keep Your Friends Close And Your Tools Closer With This Pegboard On Rollers

August 6, 2015 by George Graves 28 Comments

There’s nothing that adds more time to building or repairing something than having to walk back and forth to grab the right tool for the job. “Wait, was that a 15/16 inch socket I needed? Nope it’s a 3/4 inch! Rats!”

[Brad Justinen] shares his solution to the problem in this very simple, but well documented tutorial on Instructables. He welded up a metal A-frame, then simply added pegboard to the sides and casters to the bottom. Our first thought was if something like this could be made out of lumber for a bit more of a DIY approach, but if you’ve ever moved a tool box full of tools, you know how their weight really adds up fast. So perhaps it might be best to bribe your welder-owning friend with a 12 pack of his or her favorite adult beverage.

If you haven’t used pegboard for organizing tools, it really can be a wonderful solution to getting organized. Pegboard has many more uses as well. Check out this pegboard cable organizer, or this modular soldering platform.
