* [[24" Wall Clock]] A really big wall clock. Why? Well, cause it might look cool? Probably not. But we do use GPS to get the time! Groovy.
* [[POV display]] that spins around, giving the illusion of a large display. ([[User:DavidCary|DavidCary]])

=== [[Cellular Rotary Phone]] ===
An indepth breakdown of the Port-O-Rotary. Some clues to help you avoid audio problems with the GM862.

=== [[Das Brewmeister!]] and [[Fermenter Controller]] ===

A 125Khz RFID Reader with a simple RS232 based ring network - to allow connection of multiple units to the same control computer.

''Consider using [http://zytrax.com/tech/layer_1/cables/tech_rs232.htm#rj45 "RS-232D", aka "EIA/TIA-561"]. It has all the same wires and voltages as RS-232, but specifies a RJ45 connector.''

''Also consider RS-485.''

(What is the name of the standard for RS-485 on RJ14 ("4 wire RJ-11") or RJ45 ?)
(Ethernet? =P)

=== Battery charger ===

See [http://elecdesign.com/Article/ArticleID/1823/1823.html "Build A Smart Battery Charger Using A Single-Transistor Circuit"] by Ejaz ur Rehman.

The suggestion to add a zener diode is a good idea.

=== the Open Graphics Project ===

[http://linux.wordpress.com/2006/07/19/introducing-the-open-graphics-project/ the Open Graphics Project]
a project started by chip-designer Timothy Miller.
His goal, along with the rest of the project, known as the “Open Graphics Foundation” is to make a 3D accelerated video card which is fully documented, free-licensed, and open source.
See [http://wiki.duskglow.com/tiki-index.php?page=Open-Graphics the Open Graphics wiki].

=== [[Amiga floppy project]] ===

The Amiga floppy project:
designing, building, and programming an adapter to allow PCs to read from Amiga floppies.
"This is really designed to be a community project(hence the blog with progress reports)."

This project is the building of an external USB amiga floppy drive controller. It sits between the USB port on a Windows PC, and a regular PC floppy drive. It will allow the PC to create .ADF images from an amiga floppy disk. This device is based on a Parallax SX28 microcontroller, uses Ramtron FRAM memory for temporary track storage, and uses another Parallax component for the USB interface.

See http://www.techtravels.org/amiga/amigablog for the latest in the blow by blow attempts to get this thing off the ground!!

=== scavenge ===

Some people derive an inordinate amount of pleasure from building semi-useful objects from zero-cost junk.

In the electronics field, most of the stuff built from scavenged components falls into 2 categories:
* ham radio transmitters and receivers -- built from a few transistors, caps, resistors, and wire
* BEAM robotics -- built from the above plus motors, solar cells, ...

According to http://coprolite.com/art12.html ,
"I'd love to hear about where you found your 8048. Take a picture of the host that you remove it from (CD player, truck, refridgerator, whatever) and I'll put your picture on a page that chronicles our adventures sifting through the rubble."

=== openEyes ===
openEyes is an open-source open-hardware toolkit for low-cost real-time eye tracking.
See [http://hcvl.hci.iastate.edu/cgi-bin/openEyes.cgi the OpenEyes hardware and software] and [http://hcvl.hci.iastate.edu/cgi-bin/openEyeswiki/index.cgi the openEyes wiki].

== other lists of semi-open projects ==

=== [[WikiNode]] ===
The WikiNode project tries to link every wiki in the world together.
Our "[[WikiNode]]" links to closely-related wiki (and their WikiNode links back).

If you want to talk about something that is not quite on-topic here at Open Circuits
(say, "desktop PC case modding", or "embedded Linux programming"), our WikiNode helps you find another wiki where people love to talk about that exact topic.
The corresponding WikiNode on each of those wiki helps people who want to talk about "open hardware" to discover this wiki.

* Are [http://positron.org/projects/ the Positron projects] "open" enough to be mentioned? I especially liked the [http://positron.org/projects/acrylic_cases/ "Lasercut Acrylic Casebuilding Tutorial" ].

* Is [http://wiki.vislab.usyd.edu.au/moinwiki/PuckControl/BuildingThePuck the Vislab puck] suitable for this list?

Open source electronics

2007-04-02T06:49:17Z

193.144.127.251:

'''Open source hardware''' refers to computer and electronic hardware that is designed in the same fashion as [[free software|free]] and [[open-source software|open-source]] [[software]]. Open source hardware is part of the [[open source culture]] that takes the open source ideas to fields other than software. An example of this is the [[Simputer]] project.

Some of the impetus for the development of open source hardware was initiated in [[2002]] through the [[Challenge to Silicon Valley]] issued by [[Kofi Annan]] [http://news.com.com/2010-1069-964507.html?tag=lh]. Because the nature of hardware is different than software, and because the concept of open source hardware is relatively new, no exact definition of open source hardware has emerged.

Because hardware has direct variable costs associated with it, no open source software definition can directly be applied without modification. Instead, the term open source hardware has primarily been used to reflect the use of free/open source software with the hardware and the free release of [[information]] regarding the hardware, often including the release of schematics, design, sizes and other information about the hardware. In anyway, it includes the hardware design and element distribution on the motherboard (i.e. a [[laptop|notebook]] where one can replace elements).

With the rise of reconfigurable [[Programmable logic device|logic device]]s, the sharing of logic designs is also a form of open source hardware. Instead of sharing the schematics, [[hardware description language|HDL]] code is shared. This is different from free/open source software. HDL descriptions are commonly used to set up [[System-on-a-chip|SoC]] systems either in [[Field-programmable gate array|FPGA]]s or directly in [[Application-specific integrated circuit|ASIC]] designs. HDL modules, when distributed, are called [[semiconductor intellectual property core]]s, or IP cores.

===Organisations===
*'''Open Hardware''' ('''OH''') is a project in which [[hardware design]]ers share their work by disclosing the [[schematic]]s and [[software]] ([[Device driver|driver]]s) used in their designs. Open hardware [[designers]] meet, discuss what they are doing and ask each other for assistance in finding parts, or seek ideas to solve design problems. OH is also an opportunity to exhibit designs, so some may learn from what others have done.
