Build a Modern Computer from First Principles: From Nand to Tetris (Project-Centered Course) from Hebrew University of Jerusalem. What you’ll achieve: In this project-centered course* you will build a modern computer system, from the ground up. ...
NXP ARM7TDMI and Cortex-M3 Microcontrollers. Supports the LPC1768/LPC2368 microcontrollers. Also emulates a USB serial port for easier interfacing.
NTSC/PAL composite video output from the LPC1768 with a PS/2 keyboard for standalone operation.
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.
There is no standard mains voltage throughout the world and also the frequency, i.e. the number of times the current changes direction per second, is not everywhere the same. Moreover, plug shapes, plug holes, plug sizes and sockets are also different...
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.
an open source programming environment and electronics i/o board for exploring the electronic arts, tangible media, teaching and learning computer programming and prototyping with electronics.
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?
a small device which plugs into a $20 prepaid mobile phone to make a GPS tracker. The Tracker responds to text message commands, detects motion, and sends you its exact position, ready for Google Maps or your mapping software
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.
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.
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.
