StripInvaders

A led strip system controlled by your Smartphone or Tablet. Connect StripInvaders to your LAN and enjoy your own Lightshow!

Features:

• 15 different Light Modes, more will follow
• Stepless adjust the RGB values​​
• Stepless adjust the animation speed
• Control StripInvaders wireless with your iPhone/iPad/Android Phone/Android Tablet (OSC)
• Bonjour and mDNS support
• DHCP support
• Configure your strip (connected pins, nr. of leds) without reflashing firmware, use OSC to configure

Required Hardware:

• Arduino Ethernet
• ws2801 based led strips, I sell some at my shop
• 5v regulated power supply
• Optional: Seeedstudio Grove Base Shield
• Optional: Seeedstudio Grove - Universal 4 Pin Cable
• If you want to use the Grove Base Shield, make sure you need 2x 8-pin Header and 2x 6-pin Header, like the Seeeduino Mega Protoshield Kit

OSC Messages:

Name:   Type:   Range:   Descr:
/knbr   float   0..1     R Color Vale
/knbg   float   0..1     G Color Vale
/knbb   float   0..1     B Color Vale
/delay  float   0..1     Delay Value
/audio  float   0..1     Enable audio sync (toggle button)
/mode   float   0..1     if mode = 1, switch to next effect
/modd   float   0..n     direct change to effect x
/cfg    4x int           first byte must be 66 (magic byte), then DATAPIN, CLKPIN and then LEDCOUNT. this change is 
                         stored in the eeprom. The Arduino will reboot after the update

Effects:

00: color lines
01: solid color (white)
02: solid color wheel fader
03: solid color random fader
04: color wheel aka rainbow
05: knight rider 1 mover
06: knight rider 4 movers
07: knight rider 8 movers
08: knight rider block
09: xor 1
10: xor 2
11: xor 3
12: xor 4
13: xor 5
14: xor 6

Network:

DHCP Enabled (and needed!)
MAC: 00:00:AF:FE:BE:01
mDNS: invader.local (ping invader.local)

TODO:

• More effects (Plasma, Fire, Perlin Noise, FFT)
• Improve Audiosync Maybe using a MSGEQ7 (http://nuewire.com/info-archive/msgeq7-by-j-skoba/)
• Reduce OSC Library size
• Gamma correction
• Use ColorSets

Misc:

• One Firmware for both drivers (WS2801/LPD8806) is not possible, due size limitation.
• check http://neophob.com/2012/01/stripinvaders-howto-assemble/ for more information how to assemble the LED Strip

OSC GUI

StripInvaders provide some ready to use OSC GUI's for different OS:

• OSX/WIN Application to configure the PixelController
• PureData OSC Gui, path: OSCGUI/simple.pd (needed to configure the PixelController)
• Control OSC Gui, Android/iOS, path: OSCGUI/si.js
• TouchOSC OSC Gui, iOS, path: OSCGUI/StripInvaders_iPhone.touchosc
• TouchOSC OSC Gui, iOS, path: OSCGUI/StripInvaders_iPad.touchosc

TouchOSC

Get TouchOSC from the Apple App Store. You can use TouchOSC Editor or iTunes to copy the iPad or iPhone interface from the OSCGUI subdirectory. See http://hexler.net/docs/touchosc-editor for more information.

Control

Get it from the Google Play Store. After starting the application press on the + button on top to add the StripInvaders interface. Enter the URL https://raw.github.com/neophob/StripInvaders/master/OSCGUI/Android-Control-Phone.js for a Phone or https://raw.github.com/neophob/StripInvaders/master/OSCGUI/Android-Control-Tablet.js for a Tablet, select the StripInvaders from the Destination tab and you're ready to go.

Development Hints

The main issue is the small ROM on arduino (<32kb) when using all libraries. Tested with Arduino v1.0.1. Do not use Arduino v1.0 as there are some nasty UDP errors (duplicate packages).

EthernetBonjour

• Also due to similar memory limitations, you can only vend up to 8 services running on your board. If you want to change this limitation, edit "NumMDNSServiceRecords" in EthernetBonjour.h (but note that the WIZnet chipset on the ethernet shield only supports 4 sockets anyway, one already taken up by the Bonjour library, so 8 services might be way too much anyway. Thus, you could also lower this constant to free up some memory).

-> I use only one service: #define NumMDNSServiceRecords (1)
