Build The Enterprise Is The Biggest Open Hardware Project Ever

If you dream big, dream REALLY big. Dream spacecraft big. Build The Enterprise is a website devoted to laying out, in detail, how a primitive version of the USS Enterprise from Star Trek could be built in 20 years.

There’s a petition up on the White House’s website to assign NASA the task of a feasibility study. Only 20,000 more signatures to go! Interestingly, they decided to go with a promotional graphic that is eerily similar to that scene from Independence Day when a spacecraft blew up the white house.

iFixit Literally Opens Hardware

Part of the point of open hardware is, you know, the open part. If you can’t open it, then it’s not open. iFixit tears apart popular consumer products, then rates them 1-10 based on how easy they are to work with. Apple seems to get pretty low scores (go figure) while Google seems to get pretty high scores (clips are better than glue). They also have a huge user community uploading instructions for repairing all sorts of things.

Makeblock Is A New Modular Aluminum Extrusion System

Makeblock is here to solve your robot problems. The t-slot aluminum extrusion is a tried-and-true way of building modular frames, and even simple mechanisms. It works, but it has an Achilles Heel…the nut.

t slot nut boltThat nut has to be inserted into the slot so that the bolt can torque down on the beam. Some designs include a nut that can be inserted straight through the slot and twisted instead of needing to be slid in from one end (FAZTEK). Others turn the bolt around so that the head of the bolt takes the place of the traditional nut and the nut tightens down from the outside of the bolt (MakerBeam).

A new Kickstarter campaign does away with the nut all together. Instead of using a t-slot, they have a slot with parallel sides and just the right threading to allow you to screw in a nut at any point along the slot.

Makeblock looks like an extremely well integrated system for prototyping cyber-electro-mechanical systems. They have the modular beam system itself, but they also have their own electronics with the correct footprint to fit on the beams and adapters for common things like Lego and servos. Additionally, they have it working in the real world and appear to have the manufacturing muscle to produce a lot of the kits.

Ford Officially Backing Open Source 3D Printers

In a press release Ford Motor Company bragged about using 3D printing in general, and the open source Makerbot Thing-O-Matic in particular, to develop some of the smaller plastic parts for its vehicles. Zack Nelson, the engineer in the video, lists the easy availability of design files and community support as benefits to using the open source machine.

The full text of the press release is after the jump.

DIY Spot Welder

A spot welder can be used to permanently attach small pieces of (mostly ferrous) metal without the need for screws, rivets or adhesives. The actual science of optimizing a spot welder is pretty deep, but at the end of the day all you’re doing is heating up metal until it flows, so as long as the tool does that you can get some home shop use out of it…particularly if it’s made out of like $10 worth of materials and runs on household current. BTW, don’t mess around with high current devices unless you know what you’re doing and take all the appropriate safety precautions (like not standing in a puddle).

Here Grant Thompson of TheKingOfRandom.com explains how to make your own.

Vagina Hacking by Scanlime, Open Hardware (Emphasis on Hard)

Beth over at scanlime is no stranger to building electronics. But this time she wanted to, well…in her own words, “create something new and exciting that I can immediately use in my everyday life. It also happens to be a sex toy.” Specifically, one of those little remote-controlled vibrating egg things.

She ended up producing a hack that is remarkably polished. She even designed and 3D printed a custom enclosure for the whole thing. If she had used neon pink plastic it would have been hard to tell that it wasn’t part of the original product.

She’s got an incredibly detailed description of the project on her blog. Personally, I think the most interesting part of the hack was her solution to the power problem.

This was getting complicated fast. Lithium polymer battery, a boost converter to raise the voltage to 5V for the sonar module, charging circuit, “fuel gauge” indicator. All of this work goes into every commercial product that runs on batteries, and we often take it for granted. As far as I’m aware, though, there isn’t a great equivalent for quick DIY prototyping. The Arduino Fio board is close to what I want: an Arduino with a built-in LiPo battery charger. But it doesn’t have the 5V boost converter or any way of monitoring the battery’s charge. Without designing my own PCB, I’d need several separate components: batteryfuel gaugecharge/boost. All total, over $45 and a lot more bulk and complexity than I wanted. I was really hoping there was a better option.

It so happens that this sort of amalgamation of parts is already pretty commonplace in the form of portable cell-phone chargers. These devices are very little more than a boost converter, charger, lithium battery, and a very basic fuel gauge. Best of all, thanks to economy of scale, they’re really inexpensive. The 3200 mAH battery I used in this project was only $22, and it’s something I can reuse for multiple projects… or even to charge my phone.

This is an elegant solution that can apply to an array of different projects. Once something becomes commoditized it can drop below the price point at which it makes sense to reproduce the functionality yourself. All wireless projects need power, and with cell phone chargers becoming cheap and easy to find it makes sense to just plug one into the project’s USB slot and call it a day. Not only is it cheaper and easier, but it’s modular because you can still use it for its original purpose.

The Featherweight Book Scanner – Open Hardware by Dany Qumsiyeh

This is an open source book scanner, which is cool. But you wanna know what the coolest part is?

Okay, I’ll tell you. The coolest part is that this is an open hardware project that actually makes it easy to access not only the design of the machine but also the rationale behind the design. It’s all written up in a very approachable manner in this *.pdf. Click here for the page Google hosted the file on.

Vote For An Open Source Ecology Documentary In The Focus Forward Competition

Vimeo is being stupid and I can’t figure out how to embed the video.

Anywho, Open Source Ecology (OSE) is an awesome project that is trying to create an open source version of the infrastructure that the modern world depends on. Basically, all the machines you’d need to turn dirt into iPhones.

This is a documentary about their work that has been doing well in the Focus Forward filmmaker competition. Go watch it and add your vote!
