==Overview of DIY Hardware Approaches That Work With Vixen==

This section provides information about Do-It-Yourself (DIY) hardware that works with the [[Vixen]] software program. Vixen is a Windows (.NET Framework 2) program that runs on a PC, and is used to create and run light shows that may be synchronized to music. Here is a brief list of the DIY approaches that you can take that will work with Vixen.

===Non-Dimmable Light Controllers===

====SSR Direct Attach====

* Controlled through: Parallel Port
* Documentation: [[Solid State Relays]]

If you need 12 or fewer channels, you can just buy or build SSRs and connect them to the parallel port on your PC, and use them to turn 110VAC light strings (or just plain lamps) on and off (no dimming). These ssrs must be sourced or positive switched. From time to time there are coop buys of SSR boards,but these are usually sinked, and/or parts, to reduce your expense. You could place a couple ULN2803s and use the coop sinked ssrs. For more information on this come over to the forum and/or ask on the LiveChat.

====Kit74====
*Controlled through: Parallel Port

This is a kit with mechanical relays that can be purchased from various places. It is similar to the SSR Direct Attach, although the mechanical relays are noisy and have a limited lifespan. There are probably other similar kits available as well.

====Hill320====
* Controlled through: Parallel Port
* Documentation: http://computerchristmas.com/christmas/link-how_to/HowToId-4/How_To_Build_A_Parallel_Port_Controller_Box

This is a controller originally designed by Hill Robertson http://computerchristmas.com to allow up to 320 channels to be controlled by a PC, and requires an external power supply and SSRs. There isn't any coop board for this design at the moment. It is a more complicated design, and it is not currently recommended for newbies.

====Olsen 595/Grinch====
*Controlled through: Parallel Port
*Documentation: [[The GRINCH Controller]], [[GRINCH Controller Assembly Instructions]]
*Documentation: [[Olsen 595]]

This is a popular controller based on an approach first popularized on the http://computerchristmas.com and/or http://planetchristmas.com forums by Peter Olsen. In its first incarnation it used 8-bit 74HC595 logic chips, often with external buffers, while a later design (Grinch), popularized by Robert Jordan, uses 16-bit chips specialized for this use. There are coop boards available for both of these designs. These coop boards need external power supplies, and work with external (coop) SSR boards to control AC lighting.

There are some variations of this approach that support dimming, but they are not as popular and there aren't any coop boards available. However, using a [[Ren-C]] board can add dimming capability to a 595 or Grinch, which causes the board to operate as a Renard board. There is also an option available to run a Grinch or 595 from DMX, [[DMX to Grinch/595 convertor|here]].

The Grinch board is a good choice if you need more than 12 channels but want a board that is simple to build. It doesn't use very many parts, and is easy to assemble.

===Dimmable Light Controllers===
====Firegod====
*Controlled through : Serial Port

This is a modular system that supports 32 to 128 channels per serial port, in increments of 32 channels, with 100 levels of dimming (using pulse width modulation - PWM). It consists of a host controller module and one to four field modules. The SSRs are not included on these boards, and must be provided separately. The interface to this system is RS-232. This system is available on a coop basis from time to time, with the kits including the boards, the parts, and pre-programmed microcontroller chips (PICs). This board is intermediate in complexity to build.

The overal archecture of the system looka like this:

====Renard====
*Controlled through: Serial Port
*Documentation: [[Renard]]

This is another modular system that supports a varying number of channels, depending on baud rate selection. It supports 256 levels of dimming, and can be configured with or with PWM, or for use in DC applications. There are several coop boards available for this system with varying capabilities. It can be a fairly complex system because there are so many options. More information is available at the link listed above.

====Lynx====
*Controlled through: [[DMX]]
*Manual [[LYNX_Controller_Manual]]
The Lynx is a DIY dimmer design that uses [[DMX]] as its protocol but uses standard Cat5 cable for interconnections. It's designed to be similar to the layout of commercially available dimmers (LOR, AL, etc). It is an all in one unit that has its own power supply and SSR's built into it. You connect your DMX Cat5 and plug it in. Lights plug into female cord connections that exit from the board. It allows for a full 256 levels of dimming. The starting address is programmed via vixen. Since it uses the DMX protocol you can run 512 channels of Lynx on one DMX universe at 25ms timming.

In an effort to prevent variations in the design (leading to complications for the newer builders), insure that troubleshooting help can be provided, and keep the total cost as low as possible it is done as a modified coop. All the parts including the PCB and an enclosure are included. The necessary PIC microprocessor will come with the program preloaded so that the builder will not need a PIC programmer. A detailed instruction manual with pictures is included and should allow anyone with basic soldering skills to successfully build the controller.

===Other Controllers (Signs, Servos, etc.)===
====Ledtriks====
*Controlled through: Parallel Port
*Documentation: [[LedTriks Controller Assembly Instructions]]

This is a controller to control low-voltage LED panels, designed by Robert Jordan. These panels are typically 16 LEDs high by 48 LEDs wide, for a total of 768 LEDs. Vixen can control up to four panels through one parallel port, and can even display text.

====JEC Pixel Displays====
*Controlled through: [[DMX]]

Pixels are a stand-alone lighting fixture controlled by DMX-512. Each pixel has banks of red, green and blue wide-angle LEDs, currently six of each. Firmware is available in two versions: 3 and 4 channel. 3 channel requires a dmx channel for red, green and blue intensity. Four channel adds master intensity control to the original three.

Pixels require a stiff +12v switching power supply. Each circuit board draws ~ 130 mA at full brightness. Pixels chain together using standard CAT5 networking cable. Per the DMX spec, no more than 32 pixels should be connected together without using an optosplitter / signal buffer.

LED refresh rate is nearly 100 Hz.

More details can be found at http://www.response-box.com/rgblights

Currently in progress is a version of the firmware which will allow the DMX address to be changed in the field. Currently the address is hard-coded.
