Open Rail, or, why didn’t we think of this?

Hackaday readers familiar with the with the CNC and automated machinery scene will be familiar with MakerSlide, the open-source linear bearing system. This linear movement system composed of special aluminum extrusions and mounting plates riding on v-wheels has been used in a lot of awesome builds including the Quantum ORD Bot 3D printer and the Shapeoko CNC router. … Read the rest

Adding the Apple ‘breathing LED’ to a motorcycle

[spiralbrain] has a beautiful KTM Duke 200 motorcycle, but he’s found the factory configuration is a little bit plain. Wanting to add his own unique touch to his bike, he decided to add a ‘breathing LED’ to the parking light that slowly changes its brightness much like the LED on recent Macs.

From the factory, [spiralbrain]‘s bike uses extremely inefficient … Read the rest

Amazing 3D rendering in real-time

Ah, the 90s. A much simpler time when the presenters on Bad Influence! were amazed by the 3D rendering capabilities of the SGI Onyx RealityEngine2. This giant machine cost £250,000 back in the day, an amazing sum but then again we’re getting nostalgic for old SGI hardware.

Well, Mega is taken… let’s call it

Nah, you don’t need an Ethernet module for your Arduino

[Andy] needed a cheap Internet connection between a data-gathering Arduino and his home server. An Ethernet shield would suffice, but he couldn’t run CAT5 to the Arduino’s location. Wireless shields are hideously expensive, and after looking over the popular Zigbee modules, [Andy] had a few concerns about range and build complexity.

The obvious solution to this problem was getting a … Read the rest

Introducing Hack a Day: the retro edition

Hack a Day hasn’t change its format since 2004. Even though MAKE has gone Web 2.0 with buttons using mouseover, and Instructables has fancy drop-down menus, Hack a Day has been a constant black background, green text child of the web circa 2004. A while ago, we decided it was time for an update to our layout. Today we’re pleased … Read the rest

Bending laser cut wood without steam or forms

If you want to pretty up your project boxes, we can’t imagine anything better than [Shaun]‘s walnut plywood, laser-cut, kerf bent Arduino case. Instead of the slot-and-tab construction of traditional laser-cut enclosures, [Shaun] used a technique to bend plywood without steaming, heating, and eventually scorching his somewhat expensive plywood.

This isn’t the first time we’ve seen this accordian style laser-cut … Read the rest

Building a foundry in your backyard

[th3BadWolf] has been wanting to build a foundry for some time now. Done right, it’s a very neat tool; it’s fairly easy to do aluminum castings, and if you’re clever enough a foundry can lead to building large machine tools such as a lathe or a mill. Anything worth doing is worth overdoing, so [BadWolf] is designing his foundry to … Read the rest
