What is open source hardware? Briefly, these are projects that creators have decided to completely publish all the source, schematics, firmware, software, bill of materials, parts list, drawings and “board” files to recreate the hardware – they also allow any use, including commercial. Similar to open source hardware like Linux, but hardware centric.
This is one of the new and emerging trends we’ve seen really take off over the last few years. Each year we do a guide to all open source hardware and this year there are over 60 projects/kits – it’s incredible! Many are familiar with Arduino (now shipping over 60,000 units) but there are many other projects just as exciting and filled with amazing communities – we think we’ve captured nearly all of them in this list. Some of these projects and kits are available from MAKE others from the makers themselves or other hardware manufacturers – but since it’s open source hardware you can make any of these yourself, everything is available.
You can also call this guide… “The Open source hardware gift guide – The one and only, 3rd annual celebration of open source hardware!” – we think these are some of the best things to consider for the holidays and it supports an exciting development in hardware design.
So sit back and get ready to scroll through the list! Here we go!

The Arduino Pro is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires. The pin layout is compatible with Arduino shields. The board can be powered with a battery, and runs at 3.3V (Also check out the Arduino Pro Mini).

Open source hardware for “Spy Tech” and trouble makers
WaveBubble – Open source cell phone, Wi-Fi jammer A self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camouflaging: it is the size of a pack of cigarettes. An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc). The battery is rechargeable via a mini-USB connector or 4mm DC jack (a common size). Alternately, 3 AAA batteries may also be used. Output power is .1W (high bands) and .3W (low bands). Effective range is approximately 20′ radius with well-tuned antennas. Less so with the internal antennas or poorly matched antennas. Self-tuning is provided via dual PLL, therefore, no spectrum analyzer is necessary to build this jammer and a single Wave Bubble can jam many different frequency bands – unlike any other design currently available! To reconfigure the RF bands, simply plug it into the USB port of your PC and type in the new frequencies when prompted. Multiple frequency ranges can be programmed in, each time the device is power cycled it will advance to the next program in memory. Price: Not for sale directly, parts / everything… about $200

Games – Want to play a nice game?
Game of Life – Create colonies in LED In 1970, John Conway came up with a 1-player game called Game of Life. The Game of Life is a mathematical game that simulates ‘colonies’ that grow or die based on how crowded or lonely they are and is known for the way it creates a beautiful organic display out of randomness. Here is a design for a simple electronic project that plays Conway’s Game of Life. Make one kit and keep it on your desk, or attach multiple kit modules together to create a large display. Originally created by Dropout Design, this revision adds a few extra features. The kit is very easy to make and an excellent first electronics project. It is perfect for workshops since at the end everyone can connect their completed module together.
- Each kit displays a 4×4 grid (16 LEDs) on a 3″x3″ board
- Connect as many kits as youd like, in any configuration, to create a larger game board
- Runs off of 2 AA batteries (not included), but can be easily modified to run off of USB or wall-wart power
- On/Off button to save power, also for resetting the display

- Use any pencil – mechanical or plain. The kit comes with a 2B pencil, the softer the lead the better
- Ridiculously fun for all ages
fUSEBOX – The awesomely retro open source hardware game console! The Fuzebox is a fully open-source, DIY 8-bit game console. It is designed specifically for people who know a little bit of programming to expand into designing and creating their own video games and demos. A full-featured core runs in the background and does all the video and audio processing so that your code stays clean and easy to understand. This kit includes the PCB, pre-programmed chip, and all components including a pre-soldered video chip. All but one of the components are through-hole, so you can build it yourself without difficulty. However, it is a 1-2 hr project and its best to have used your soldering iron before this project. Price: $70.00

Bio/Medical – Open up and help someone
OpenEEG an EEG design that is OS & available as a kit or assembled Many people are interested in what is called neurofeedback or EEG biofeedback training, a generic mental training method which makes the trainee consciously aware of the general activity in the brain. This method shows great potential for improving many mental capabilities and exploring consciousness. Other people want to do experiments with brain-computer interfaces or just want to have a look at their brain at work. Unfortunately, commercial EEG devices are generally too expensive to become a hobbyist tool or toy. Price: Various, check site.
Open Prosthetics CAD designs for prosthetics The Open Prosthetics Project is producing useful innovations in the field of prosthetics and freely sharing the designs. This project is an open source collaboration between users, designers and funders with the goal of making our creations available for anyone to use and build upon. Our hope is to use this and our complementary sites to create a core group of lead users and to speed up and amplify the impact of their innovations in the industry. Price: Donate.
Phones – Open phone home!
P04 Four Port IP-PBX – Open source asterisk box! The goal of this project is to provide free hardware designs for telephone systems. Both the hardware and software are open. You are free to copy, modify and re-use the hardware designs. The hardware for a complete embedded Asterisk IP PBX (including multiple analog ports or a T1/E1) can be built for a few hundred dollars.

3D Printing – Replicate with replicators!
RepRap – Print anything, in 3D RepRap is short for Replicating Rapid-prototyper. It is the practical self-copying 3D printer shown on the right – a self-replicating machine. This 3D printer builds the parts up in layers of plastic. This technology already exists, but the cheapest commercial machine would cost you about â‚¬30,000. And it isn’t even designed so that it can make itself. So what the RepRap team are doing is to develop and to give away the designs for a much cheaper machine with the novel capability of being able to self-copy (material costs are about â‚¬500). That way it’s accessible to small communities in the developing world as well as individuals in the developed world. Price: Various (see site for kits & more!)…
Fab@Home – Make objects and more in 3D, the open way! Fab@Home is a project dedicated to making and using fabbers – machines that can make almost anything, right on your desktop.
