It has never been a better time to understand the components that fit together to make the hardware we use work. To do that, lets look at my five favorite open hardware projects.
First, what do I mean by open hardware? I mean that the components that make up a device are available for the user to see. No secret formulas. The ingredients are completely transparent, and if you chose, you can source the raw parts and assemble them yourself. You can also learn from the process of assembly and with a team spirit share any problems encountered, then improving the formula of the device. For example, you could suggest better parts or improve the code to make it run faster.
Of my top five here, many were proposed on crowdfunding sites for startup funding. This gives the wider public a chance to contribute to the initial startup costs of the projects. Benefits can be offered in return for a contribution. For instance, a minimum donation may credit the contributor with a founder mention on the homepage of the website, and a higher contribution may reward the funder with first access to the initial run of the product. Ultimately, a target for the startup fund is set and if the target is hit, rewards are sent, to the "backers". And, if the campaign fails to hit that target, no money is withdrawn.
The Pi-Top is a laptop with a Raspberry Pi as the motherboard and a build with open architecture, so if you have to buy components separately you are able to do so. Improvements to the plans only benefit the community. With the 3D plans also available, what better way to make your Pi portable than an established campaign? If successfully funding, you be able to 3D print the case yourself or order the kit pre-printed for home assembly.
If you're all fingers and thumbs, the RaspiTab is the project for you. It's commited to open principles, with a Kickstarter campaign to demonstrate and re-inforce their enthusiasm for open. It is rather exciting to imagine building an app directly on a motherboard that you can remove with the application of a standard screwdriver. If you’ve ever had to upgrade your phone because of a cracked screen, you'll see the appeal.
I was really excited about this project and was surprised when it didn't hit it's funding target. The team promises to come back with a stronger campaign and recently published an image of the board, a PCB designed to the specifications of the Raspberry Pi Compute Module. This offered vendors the opportunity to develop boards to the specification of the raspberry pi and ready to run images printed to run on the standard board.
The ultimate electronic wireless kit. This is a range of very small components that are beautiful. They were on display at MozFest and are tiny, around the size of an adult thumb. They follow the IF sensor receives input, then a button or a switch performs whatever task you have assigned the output. For example, turn the fan on or spin the motor, and this is allocated via the Lego like computer interface. This team has a commitment and understanding of the need for open hardware and the array of devices available to incorporate into your project or even use as a stand-alone desk toy. In the video on their site, see the fan used as a bubble blower and a hand-waving doorbell, which might offer a visual signal for someone who cannot hear the doorbell.
These boards come in pairs. A lead scout and a field scout. The lead scout can communicate with your wireless network and the Pinoccio network which will be a network of field scouts communicating on a mesh network. A mesh network is a wireless network which runs on an independant frequency to your wireless Internet network. How about this idea? A set of field scouts set up at a standard distance with cameras set to trip a second apart the first with an infrared beam as the trip switch to record the classic horse running sequence. This was the classic experiment Eadweard Muybridge conducted to prove that a horse ran by lifting it's legs independantly, leading to the birth of the moving image and consequently film.
