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 the OpenEyes hardware and software and the openEyes wiki.

RepRap

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[4]

Other open hardware 3d printing projects:

TwentyDollarWikiDevice

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

GPIB

improved flashlight design

"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 ..."

Other Lists of Semi-Open Projects

  • UHF FM BUG with ButtonCell battery ( http://www.elektronika.ba/408/fm-bug-420-480-mhz/ ) "This bug is 100% made from an old Nokia GSM phone! It operates at 434 MHz and reception can be achieved on a modified TV tuner or 70cm band HAM radio."
  • microcontroller alternatives lists a bunch of "small PCBs" (is there a better name?) designed for hacking and prototyping, that already have the processor and a few other super-common things built in ... so you don't have to start *completely* from scratch.
  • ThinkCycle "ThinkCycle is a ... non-profit initiative ... supporting distributed collaboration towards design challenges facing underserved communities and the environment. ThinkCycle seeks to create a culture of open source design innovation"
  • Are the Positron projects "open" enough to be mentioned? I especially liked the "Lasercut Acrylic Casebuilding Tutorial" .
  • Is the Vislab puck suitable for this list?
  • PICList & JAL_List free PCB contest "this will encourage people to publish designs and get more good ideas out into the real world for everyone to see." (So, are these "open" circuits?)
  • http://ePanorama.net/ has a bunch of schematics and a web discussion forum. Are they "open" enough to mention here?
  • "Yet Another One-hand Keyboard" ( http://chordite.com/ ) "The firmware included in the download lets an Atmel AVR '2313 microcontroller interpret chords and talk to a PS/2 port." -- it's not completely open, but the license allows you to immediately download, for free, lots of technical information and a license to build up to 5 of your own. Building more than 5 requires some sort of payment to license the patent on the hardware configuration. (The software appears to be open source). There seems to be an associated Yahoo mailing list. What is an appropriate way to invite John W. McKown and others on the mailing list to use a wiki such as Open Circuits to maintain a FAQ?
  • FC's Electronic Circuits ?

  • GSM SMS Controllers ( http://www.elektronika.ba/503/gsm-controller-v2/ ) "TwoWay Thing (GSM Controller v3) is a device that allows you to control appliances using SMS messages. 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.
