Minimal Arduino with 8MHz internal clock

Build your own DIY Arduino board with only one passive component, it is very easy and simple. This is probably the most minimal ATmega328 based Arduino.
 
Part list
  • ATmega328
  • 28 pins IC socket
  • 10K resistor
  • Strip board 
This is a tutorial shows you how to build your own Arduino, I name it as SalMonDuino which is derive from my name (SM Ching). SalMonDuino is an modified version of original post written by Serisman, features include:
  • Using stripboard eliminate the trouble of drilling PCB holes
  • Simple circuit design uses minimum of components
  • Using 16MHz resonator as clock source
  • Prototype area
Aarduino communicate with Vixen
Vixen is a free and popular light show creator software. With a PC and some hardware, anyone can have a professional-looking lighting display synchronized to music.
 
The latest version is Vixen3, the most attractive feature is supported for preview. Compare to Vixen2, Vixen3 is a bit difficult to use & lack of some features in Vixen2. Please correct me if I'm wrong.
 
This tutorial is based on Vixen2, please download Vixen2 and install it to your computer. Prior to Vixen2, you must have install Microsot.NET Framework 2.0 in your computer.
Explains how to bridge network using two wireless routers, the first (Host) router is configure as Access Point & the second router (TL-MR3020) is configure as Client mode. Same method should apply to all other OpenWRT routers as well.
 
Prerequisites
  • Host router configure as Access Point. If you already setup a wireless internet connection in your house, usually your modem is configured as Access Point mode.
  • A working OpenWRT on TP-LINK TL-MR3020 Portable 3G/4G Wireless N Router
 
The routers is configure as two different subnet, assume using settings below as the example.
  • Host router IP: 192.168.1.1
  • Host router subnet mask: 255.255.255.0 or 255.255.0.0 if you want to access 192.168.0.x from 192.168.1.x
  • Host router SSID: ABC
  • Client router IP: 192.168.0.1
  • Client router subnet mask: 255.255.255.0

TP-LINK TL-MR3020 + OPENWRT + WEBCAM

This project uses an inexpensive TP-LINK TL-MR3020 Portable 3G/4G Wireless N Router with an Linux UVC supported camera to create an IP Camera that can be placed in a good location for surveillance.
