GreenBee Reloaded!!

Hi Everyone,

There has been some problems, some modifications needed in the GreenBee project made By Amit Radhakrishnan. Chinmayananda Das and ricky17 (from forum) took the challenge to make this project working again. After so much of hardware, project is Up and working.

Download section is not update with the new Black book (project report) and circuit diagram is updated. Code is available in a text file and you have to get the hex file yourself. here are few words from Chinmaya

hello readers

i m Chinmay das. i m very happy dat u hv shown interest in this project. but before start working on this project you must know somting.

1.making a project is not just soldering the ckt n loading codes.
2. whn you make a project you will learn a lot of practical things(say experince), which you will never get 4m any book.
3. To make a succesful project u need work hard, a lot of dedication, passion to work. so after lot of request 4m other people , i m nt givng the hex codes. i m given only the text version of update asm codes. i want u guies to work on it. so u find compiler software. make asm file n generate the hex codes. i have also put very small threadsin ckts... so ur job is find dos fault , ask us in the forum n v will ans dem.
4.And dont worry abt Black book. i m also uploading the .doc version of my project report to reduce ur stress. so keep working

All the best
Chinmay Icysun

Proteus Model - Nokia 3310 LCD
Hey friends,

If you are afraid of soldering Nokia LCD with your hands and still want to check your code..
here is a solution for you..

One of our Russian friend "Tanu Sha" (hope the name is correct) has made this sweet Nokia 3310 LCD model which simulate the original Nokia LCD.

This Proteus model has been tested with the following versions of Proteus VSM Co-simulator

Proteus v6.9 SP5
Proteus v7.2 SP2
Proteus v7.4 SP3

In other versions you might see error like "dll not authorized" something.. we really dont have any solution for that. anyways.. have fun using this model..

here are some screenshots:

Home Automation using Mobile

contact@nospam.com (Ajay Bhargav) — Sat, 02 May 2009 03:41:17 -0700

Home Automation using Mobile

Dear members,

A new project idea is coming on the way..
Now you can control you home appliances from your mobile phone.
Home automation server which you all know by name of "HA Server" will remain almost same, but on the other end instead of using telnet you will be using your mobile phone to control your appliance.

A simple J2ME based client software that will interact with your server and appliances, and a nice GUI interface makes it easy for you to navigate and control your appliances. All you need is a java based phone with minimum MIDP2.0 support. I guess most of you will be having one.

I wont make you people wait a lot here is a screenshot of what coming on Rickey's World.

Keep checking for updates..

PIC Basic Project: Graphical temperature recorder (16F628 + LCD Nokia 3310 + DS18B20)

Gioppy wrote ...

Here a nice graphic temperature recorder.

Features
It shows 60 samples. (new values scrolls left the plot)
Temperature is sampled every 15 Sec. and averaged.

The following parameters are configurable.
Sampling rate 15 Sec. to 3.825 Sec.(255*15)
Initial scale -30°C to 90°C
Scale resolution 1°C to 20°C division
Display contrast level

Configuration parameters are stored in eeprom.
To change parameter only the eeprom must be reprogrammed (NOT the code)
Refer to source code to know where they are stored.
N.B. Negative temperature for the initial scale value must be stored in 2 compliment form.

Source code attached.
(sorry for the Italian comment in the code, i have not time to translate)
