* [https://apertus.org/ apertus° - open source cinema] Open Technology for Professional Film Production
 +
 
 +
AXIOM introduces the first professional, extendable and modular cinema camera platform entirely based on free software, open design and open hardware.
 +
 
 +
This project was created by film-makers who were fed up with the expensive and limited tools they had to work with every day. The desire to have devices/technology without limitations, that are tailored exactly to the film-makers needs sparked the creation of the apertus° project and still keeps it going many years later.
 +
The created technology will be freely adaptable, just as the generated knowledge are made freely available. The AXIOM product line is the result of the ongoing endeavor to redefine the industry well beyond the DIY garages and hobbyist labs the project started in: to build the very first open digital cinema camera from scratch and to create a platform for film-makers, creative industry professionals, artists and enthusiasts.
 +
 
 +
AXIOM was inspired by the earlier [[Elphel camera]] open hardware camera.

=== RetroBrew Computers Project ===
 +
The RetroBrew Computers Project (also called "Home Brew Computing Project" ?) began with the Andrew Lynch (N8VEM) Single Board Computer (SBC), a home brew Z80 small computer project. It is made in the style of vintage computers of the mid to late 1970's and early 1980's using a mix of classic and modern technologies.  Its purpose is to entertain through education.  It is intended to be used to teach and promote principles of electronic computer design.  It is a solely non-profit educational project and is not intended for any commercial application.  Please see the wiki for detailed information on the N8VEM project.

What is a good way to break this long page into shorter pieces? Discuss: Talk:Projects#too_big_to_edit.

Contents

Open Circuits[edit]

These should be projects or links to projects that are open, at a minimum in the sense that there is enough information so that others can reproduce the project. Lets stay away from sites that are just show cases without the details. In no particular order:

Other open-hardware keyboards[edit]


AXIOM Beta

Open-hardware camera system[edit]

AXIOM introduces the first professional, extendable and modular cinema camera platform entirely based on free software, open design and open hardware.

This project was created by film-makers who were fed up with the expensive and limited tools they had to work with every day. The desire to have devices/technology without limitations, that are tailored exactly to the film-makers needs sparked the creation of the apertus° project and still keeps it going many years later. The created technology will be freely adaptable, just as the generated knowledge are made freely available. The AXIOM product line is the result of the ongoing endeavor to redefine the industry well beyond the DIY garages and hobbyist labs the project started in: to build the very first open digital cinema camera from scratch and to create a platform for film-makers, creative industry professionals, artists and enthusiasts.

AXIOM was inspired by the earlier Elphel camera open hardware camera.


SD Card Bathroom Scale[edit]

On SD Card Bathroom Scale project I hacked a cheap commercial digital bathroom scale, for write (log) my weight variations over time, on a memory SD Card. I write the information (time + weight) on a comma separated values (CSV) file (weight.csv) so I can quickly build a graph using OpenOffice.

RetroBrew Computers Project[edit]

The RetroBrew Computers Project (also called "Home Brew Computing Project" ?) began with the Andrew Lynch (N8VEM) Single Board Computer (SBC), a home brew Z80 small computer project. It is made in the style of vintage computers of the mid to late 1970's and early 1980's using a mix of classic and modern technologies. Its purpose is to entertain through education. It is intended to be used to teach and promote principles of electronic computer design. It is a solely non-profit educational project and is not intended for any commercial application. Please see the wiki for detailed information on the N8VEM project. N8VEM Mailing List RetroBrew Computers Wiki (was: N8VEM wiki )

RetroBrew Computers Projects includes boards supporting the Zilog Z80, Motorolo 6809, MOS Technology 6502, as well as ISA bus and S100 bus.

PINGPONG-CDC : A Homebrew USB FHSS RF Modem [edit]

The PINGPONG-CDC project is a homebrew USB frequency hopping spread spectrum RF modem (FHSS). The modem is based on the Microchip 18F2550 and the Semtec XE1205 RF module. The module does not include a MAC or protocol layer. That is what this project implements. The project demonstrates how to write a FHSS MAC layer and use USB to interface it with a PC through CDC and WinUSB. Since the protocol is not hard-wired, it is easy to change the software to experiment with different protocols. A utility for pairing and configuring modems is included. The schematic, firmware, and host C++ software is provided.

XE1205-RNDIS : FCC Legal Frequency Hopping Spread Spectrum USB Wireless Ethernet [edit]

This is the PINGPONG-CDC project that emulated ethernet through the RNDIS driver in Windows rather then a serial cable replacement. Full source code is provided.

Serial Communication Protocols[edit]

PG31 GPS RS232 Dev Board[edit]

A simple RS232 example project that takes 3.3V TTL serial and outputs to a super-common RS232 connection. Insto-NMEA!

PG31 GPS USB Dev Board[edit]

A great example project using the CP2102 USB to TTL UART IC as well as some basic battery holder info.

RS232 Dev Board[edit]

A simple RS232 example project that takes all the power it needs from the serial port. Use it to power your microcontroller and communicate between serial port and microcontroller. Takes advantage of the fact that pc serial ports will accept 0-5V rather than the RS232 standard of around negative 10V to positive 10V. Very convenient - no external power required! Note that you may use either a 5.1V Zener or a 5V regulator.

RS232 RS485 USB Converter Board[edit]

Aim to build a general Converter between different Interfaces.

Number Six[edit]

"#6" (the son of Chalk Roach) is a ultra simple microcontroller development board for Atmel ATmega32 = 16MHz, 2KB SRAM, 16KB Flash

LED and POV displays[edit]

Led displays range from a battery and an LED which light up ( cool!, add a magnet and you have an led throwie ) to microcontroller led projects, either Smart Led ( Led with a microcontroller so that it blinks, reacts to the environment, or shifts color ) or Led Arrays ( or led matrix ) that do simple graphics and or play games, or POV devices where what you see depends upon you persistance of vision ( which can include some led arrays ). You can probably dig up more using these terms in google.

Our Own Projects[edit]

Off Site[edit]

See the links at the bottom of POV display.

Das Brewmeister! and Fermenter Controller[edit]

Home controller[edit]

Program your appliances to operate automatically in conjunction with your weekly and daily schedule, manually turn them on/off from your PC or use the controller as a process ON/OFF controller to regulate some kind of physical variable to the desired value.

Battery charger[edit]

See "Build A Smart Battery Charger Using A Single-Transistor Circuit" by Ejaz ur Rehman. But be sure to read the "Reader Comments" at the end. The suggestion to add a zener diode is a good idea.

the Open Graphics Project[edit]

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 the Open Graphics wiki.

Amiga floppy project[edit]

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[edit]

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

In the electronics field, the most popular 2 categories of things to build from scavenged components are:

  • ham radio transmitters and receivers -- built from a few transistors, caps, resistors, and wire
  • BEAM robotics -- built from the above plus motors, solar cells, ...

Other things to build and tips on scavenging at Free_From_Salvage.

openEyes[edit]

RepRap[edit]

RepRap is an open source project to create a 3d printer or fabber machine. There is tons of information available on its website. The current iteration is a 3 axis cartesian robot with 2 extruder heads: a Thermoplastic head that extrudes plastics like HDPE, ABS, and CAPA, and a support material head that extrudes a water soluble material to support the build process.

The Biollante project is a kind of RepRap that uses a 6 axis Stewart platform. Can devices from a mechanical model library be fabbed with RapRap? The article "Self-reproducing machines" goes even further than just 6 identical parts -- it suggests that "self-reproducing machines composed of many identical microscale modules" may be a better design than the original RepRap design where just about every part is unique.

"This is the meta-problem of engineering: Design a machine that can design other machines." -- Hod Lipson[13]

TwentyDollarWikiDevice[edit]

Challenge: Build a Wiki Device with a parts cost of no more than twenty dollars which is usable as a portable wiki. Include feature to make it compatible with a desktop or laptop computer's PersonalWiki, with a connector allowing this use. -- http://c2.com/cgi/wiki?TwentyDollarWikiDevice

"hardware portable wiki for taking notes with an auto-merging functionality when you are very close to Internet or your computer." -- http://communitywiki.org/AlexandreDulaunoy

Could you maybe build it out of a "$12 Computer" ? "$12 Computer: Playpower Wants to Save the World 8 Bits at a Time"[14]

How close is the Kiwi project to acting like such a "wiki device"?

breakout boards[edit]

These are three boards that I designed for a specific project and found them very useful. Each of these boards uses the phoenix contact plugable terminal blocks. The 50-pin breakout board is for a 50-pin ribbon cable. The LEM breakout board is for LEM AC/DC current sensor. The power supply breakout board is for a +5v +/-15v power supply.

Eyes for Open Robot[edit]

Is there a simple way for my Java application to fetch the latest camera image in an Array of pixel values?

  • OpenHDCapture: capture (analog) High Definition Video 1280x720 at 30fps, and convert to some digital format to stream over USB. (Rather than a lot of expensive electronics to directly produce tightly compressed video, it has very little compression to reduce the cost of the hardware and the amount of CPU effort to uncompress it while watching live video).

robot[edit]

Wiegand reader simple controller[edit]

The PICmicro 16F628 decodes Wiegand protocol coming from card reader. If the card matches one of the 40 cards in EEPROM, it turns on the light (opens the door). Schematic and source code published under GNU terms.

The card is a duel Audio 1.0 + generic interface composite device with the generic interface being handled by WinUSB. The schematic, card firmware, and host C++ software is provided.


An acceptable third generation PostScript printer[edit]

"Ask the Guru: A Third-Generation Printer" article by Don Lancaster 1990 http://www.tinaja.com/glib/guru60.pdf lists specifications for "An acceptable third generation PostScript printer." Would this be a good "open hardware" project ?


the Kestrel[edit]

The Kestrel is a grass-roots computer design employing half-way modern technology, where *EVERYTHING* is documented openly. Other goals: Instant on, (nearly) instant off. Fun to build. Fun to use. Fun to expand. The creation of a vibrant and healthy user and developer community, capable of supporting itself on both software AND hardware fronts.

WikiNode[edit]

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.

Clocks[edit]

arm7-oled-clock is a clock hardware/software project for a clock with a graphic organic led display running on an atmel arm7 microcontroller.

Here is the arm7-oled-clock's project page on google code.

A really big wall clock. Why? Well, cause it might look cool? Probably not. But we do use GPS to get the time! Groovy.

Tide Clock uses the low-power LinuxStamp board (another OpenCircuits project) to calculate daily tides at almost any location. Tide predictions are displayed on a bar graph using 12 motorized lead-screws to move the 'bars'.

improved flashlight design[edit]

"Shake to Charge Flashlight" designed by David A. Johnson, P.E. has a sketchy outline of an improved flashlight design. "Knock-off Flashlight Trades off Light Intensity for Duration" has some further comments.

One interesting idea: "... it might be powerful enough to charge up a dead automotive lead acid battery after a few minutes of string pulling to start a car. Such a device might be small enough to fit into a car’s glove box ..."

"Virtual" USB Keyboard/Mouse System[edit]

"Virtual" USB Keyboard/Mouse System - Use your laptop as a keyboard/mouse for another computer. "This project is a computer interface that will allow you to hook up your computer to another computer--for example, a "headless" computer-- as a USB device, and use your laptop as a keyboard/mouse on the other machine.

There are 2 mini-USB connectors on this device. One side plugs into your laptop, the other side plugs into the computer without a keyboard. You type on the laptop, and the results will appear on the other machine. It will require special software on the laptop-side, but the destination computer should not require special drivers."

There are also 4 inputs for connecting sensors so the device will send an alarm SMS or even call you to report an alarm condition. The device draws very little current and is being powered by phone’s battery which is a great thing. Nokia should be constantly charged or supplied with some sort of external power for long term operation."
  • Phone-call alarm alert ( http://www.elektronika.ba/505/phone-call-alerter/ ) "After programming just supply power to the device.
