Everyone heared about the Arduino for Atmel. Now it’s posible to work with the modern PIC and use a arduino like board, the Jaluino.

“JAL (Just Another Language, version 2) is an open source programming language built for programming PIC microcontrollers. If electronics is your thing, JAL is for you!”

That’s cool, on http://blog.section9.co.uk/2010/03/iphone-rfid-reader.html you can see the work process  in pictures. The RFID chip is from http://www.id-innovations.com/new%20launch.htm.

“The idea behind this project is to see what the iPhone’s serial is capable of and to try and have a little fun with RFID along the way. This reader works with the low frequency (125Khz) tags but I have a half working version for MiFARE Hi-Frequency as well.”

For just $49 you can start with mobile development. And yes the watch shows the time out of the box.

“Overview

The eZ430-Chronos is a highly integrated, wireless development system based for the CC430 in a sports watch. It may be used as a reference platform for watch systems, a personal display for personal area networks, or as a wireless sensor node for remote data collection.

Based on the CC430F6137 <1 GHz RF SoC, the eZ430-Chronos is a complete CC430-based development system contained in a watch. This tool features a 96 segment LCD display and provides an integrated pressure sensor and 3-axis accelerometer for motion sensitive control. The integrated wireless feature allows the Chronos to act as a central hub for nearby wireless sensors such as pedometers and heart rate monitors. The eZ430-Chronos offers temperatureand battery voltage measurement and is complete with a USB-based CC1111 wireless interface to a PC.

The eZ430-Chronos watch may be disassembled to be reprogrammed with a custom application and includes an eZ430 USB programming interface.

What’s Included:

• eZ430-Chronos wireless watch
• eZ430 USB programming and debugging interface
• CC1111 USB RF access point
• Mini Phillips screwdriver
• CD containing documentation and development software”

A beginner’s reference to the programming syntax of the Arduino microcontroller.Includes information on program structure, variables, datatypes, arithmetic, constants, flow control, and most of the common functions of the core library. Also includes an appendix with schematics and simple programs for several common tasks.

“It has 2 analog inputs and can supply 5V ont the 4 pins header on the right. One of the inputs can be scaled down with the trim pot.
The firmware in the Tiny45 is written in C and compiled with Winavr and usb source code from obdev. As you can see, there is no crystal , the software sync the internal 16.5Mhz pll clock with the USB clock.
The cost with a home made pcb is around 5€.
Of course, do not expect 1Gs/s HID does not alow that data rate ! But it is using a 10bits AD.”

For those who’re to young for an original apple bought in the shop, here is the ultimative chance to get their own one

” The replica 1 is a functional clone of the apple 1 computer created by Steve Wozniak in 1976. This was the computer that Steve Jobs and Woz used to start Apple Computers in 1976. The latest version of the replica 1 is labeled SE for Second Edition. The replica 1 functions exactly like the apple 1 with many of the same components like a 6502 CPU and 6821 PIA. It comes with 32K RAM and 8K EEPROM. Addtional features like a ps/2 port, serial, USB port, ATX and DC wall power supply connectors makes the replica 1 a fully functional computer system for todays collector or hobby builder. Available as a kit or assembled, the replica 1 is sure to give you hours of fun and excitement as you relive the glory days of computing. As a new feature, a full blown assembler called Krusader written by Ken Wessen was added to the EPROM space giving the user the ability to assembler 6502 programs right on the replica 1 without a PC. Write 6502 machine code programs using mnemonics instead of just programming hex code into the memory. This added programming tool makes the repica 1 not only a nostalgic computer but a great learning tool and introduction to microprocessors.”

Or the non-hardware alternative, the apple I emulator:

“Pom1 is an Apple 1 emulator and is being ported to C from the original Java version. It uses the Simple DirectMedia Layer library and works on most platforms”

Connecting a Bronkhorst MV-306 via RS232 to the computer is a easy thing, when you don’t forget to set the rs232 signal ground to ground. All you’ve to do is connect PIN 2 (RxD Receive Data), PIN 3 (TxD Transmit Data) and PIN 5 (Signal Ground) with the Pins of the MV-306. The pinout of the MV-306 is 1 Tx-RS232, 6 Rx-RS232 and PIN 4 and 8 are ground.

Use this setup and the things works just fine:

RS232 PIN 2  <–RxD–> MV-306 PIN 4

RS232 PIN 3 <–TxD–> MV-306 PIN 1

RS232 PIN 5 <–Ground–> MV-306 PIN 4,8

This works right for me, i’m not responsable for any damage happens to you or your equipment.

“My Z80 microcomputer is hand wired using the wire-wrap prototyping technique. This method uses thin 30 gauge wire, a special wire-wrap tool, and wire-wrap sockets. The sockets have 1/2 inch long square posts, which you use the tool to wrap (or twist) the wire onto the post. As long as you have 5 or more wraps on the post for a single wire, the connection is semi-perminant. This method was used because it’s easy to change connections and is faster than soldering each wire. Wire-wrapping was a popular method used in building early computers. In fact, the AGC computer used for the NASA Apollo missions were completely wire-wrapped! After I finished my computer, I went through more than 350 feet of wire!”

“This article shows how to build a small, cheap and simple frequency meter, without any fancy, out of reach components. The simple proposed design can measure frequencies up to 40 Mhz with errors below 1%! This degree of precision will be more than enough to debug most of your analog and digital circuits, and will give you the ability to analyze many aspects that you were unable to see before.”

“Essentially he took the MyVu headset, removed one of the eye pieces, and mounted the other to his glasses to that he could see his surroundings and the UX’s screen at the same time. The MyVu is attached to the UX through the A/V output port on the UX’s port replicator dongle. With some additional addons he provided his UX with extra battery life via an external battery, and several input methods to communicate with the UX while the rest of the kit resides within the backpack.

Components include:
Main system:

• Battery geek: BG 14-18-60External battery (60wh)
• Sony UX380N
  • VGA/TV/LAN Dongle
• Motorola iDen i425 (for next-to-nothing (but half dial up speed) always-on internet access)

Input/Output:

• Modified MyVu Crystal Head Mounted Display
• Bluetooth enabled cellphone (text and mouse input)
• Bluetooth stereo headset (voice input and stereo output)
• ThinkOutside Stowaway Bluetooth Keyboard
• Logitech Bluetooth Mouse
• Bluetooth Frogpad (text input)”

“Familiar with the concept of hardware keylogging? A hardware keylogger is a perfect solution for monitoring user activity, at very low risk of disclosure. A hardware keylogger is a purely electronic device, so no access to the operating system is required, no traces are left, and software has no possibility of detecting such a device. However, the hardware keylogger concept inherits one weakness: physical access to the keylogger is required for retrieving captured data. This problem has finally found it’s solution: a Wireless Keylogger.”

” This project involved making a S.M.A.R.T (Self-Monitoring, Analysis, and Reporting Technology) Thermostat which could be accessible over the internet. This project combines several elements of embedded electronics, all while keeping on the theme of Home Automation. This page is a quick overview of the project; full documentation including EagleCAD board schematic & layout, as well as the Source code, can be found at the bottom of the page.

When designing this project, I wanted it to conform to these requirements:

• Remote control and monitoring via Web
• Upfront control and monitoring via LCD and pushbuttons
• Remote Monitoring, Data Logging & Graphing”

“The open source Google Android G1 phone seemed like an obvious platform for wireless robotic control, so we created an Android-based console. After running this first with the ground-based Surveyor SRV-1 robot, we made a few small modifications and used it to control the Surveyor YARB. The tilt sensors in the Android phone work quite nicely for rotor control – we have proportional steering so the amount of tilt controls the amount of power, and live video is displayed on the Android screen from the blimp’s onboard Surveyor SRV-1 Blackfin camera, carried via the same radio channel that sends the control signals.
The project is hosted on Google Code at code.google.com/p/srv1console/ as well as www.surveyor.com.”
