2.4GHz parabolic mesh dishes from Chinese cookware scoops & a USB WiFi adaptor! Called "WIFRY","WOKFI" or "WOKTENNA" (12"= 300mm diam) shows 12-15dB gain (enough for a LOS range extension to 3-5km)
allows you to control your computer with a simple remote, like the one you already use for your TV-set. It's very useful when you want to control a DVD or an mp3 player without having to stay at the keyboard.

four-channel GPS receiver using a repurposed FPGA board from a previous frequency synthesizer project. Connected to a PC running a console app, the receiver is capable of tracking four satellites simultaneously, which is good enough to capture lat, long, and altitude.
Our bodies are biologically based and therefore are not equipped to communicate with electronics efficiently. New research could make it possible to genetically engineer our cells to be able to communicate with electronics. The development has the potential to allow us to eventually build apps that autonomously detect and treat disease.

BEK, Bergen Center for Electronic Arts, is a non-profit organization situated in Bergen, Norway, which main aim is to be a national resource centre for work within the field of arts and new technology. BEK works with both artistic and scientific research and development and puts into practice an amount of mixed artistic projects. It also practices an educational program that includes courses, workshops, talks and presentations. BEK runs its own server and hosts several mailing lists and web pages for cultural organizations, artists and artistic projects.
The practical work supporting Chapter 4 introduces you to using an oscilloscope to display V/t graphs. This is a very powerful technique for investigating and understanding circuit behaviour and for correcting circuit faults.
Every object and surface in our environment has a whisper; subtle tremors and vibrations that are usually undetectable to the human ear, produced by the activity and movement of daily life. What if these sounds were audible? OTTO (Greek for 'ear') picks

Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
This is an electronic digital caliper to computer (RS-232) interface. This will work with the inexpensive calipers, micrometers and height gauges that are typically made in China. The connector on the measuring instrument will have 4 pins, and the owner's manual will typically describe the output as 24 bit 90 kHz synchronous. This does not work the name brand instruments - Fowler, Mitutoyo, Brown & Sharpe, etc.
A remote control car that can be driven over the internet or with a laptop wirelessly from up to 500m away. It has a live-feed network camera so that it can be driven without line of sight and a horn so that you can honk at people.

A PAL -- a "Permissive Action Link" -- is the box that is supposed to prevent unauthorized use of a nuclear weapon. It's supposed to be impossible to "hot-wire" a nuclear weapon. Is it?
Nice little guide to building an IR transceiver - uses the USB port for stable 5V, but includes a link in the comments to a decent circuit diagram that uses a voltage regulator and therefore doesn't need the USB port for power.
basically the Flash Nap project with a few extra features and some work. It's also a minimal version of "Light/Sound" hypnosis machines that cost hundreds of dollars, but if you have parts, this one will cost just a couple of bucks. NO PROGRAMMING REQUIRE
Qualcomm is ending its consignment production partnership with Samsung Electronics, choosing to go with TSMC for its next 7nm process-based APs. Read on!
