Increased Adoption of Intelligent Lighting Control Devices in future owing to the boom in Commercial Establishments

Request for sample copy of report at: https://goo.gl/b7WoXq

The intelligent lighting controls comprise different components that include sensors, ballasts & LED drivers, dimmers & switch actuators, microcontrollers, transmitters & receivers and intelligent luminaries. Ballasts & LED drives segment is forecast to garner the highest revenue though out the analysis period. Intelligent luminaries segment would grow rapidly, registering a prominent CAGR during the forecast period owing to ongoing research and low priced product launches for integrated luminaries.

Go help their kick starter! Maybe we'll finally have a decent way to get faders and knobs for an open source console!

Well I only control the pan, tilt and dimmer attributes, leaving the mouse/touchscreen free for use.

Completed this morning: a two-line DMX/RDM sniffer using the Saleae Logic device. It's about a quarter of the cost of the commonly used (single line) commercial unit and Saleae provides an SDK so you can build your own frontend.

Thanks to +Jeffrey Newton  for helping build the case, +Joshua Moyerman for the boards and +Sean Sill  for answering my questions.

What is your opinion for using CAT5e instead of Belden 8741 to carry DMX512 singal

Like DMX, 2-channel AES also uses differential signaling, same +/- 5 V differential signal and about same characteristic impedance. There is a test of how long cables can work with AES, where cables made for and sold as "AES" is compared to shielded Cat.5 as well as regular microphone cable of good quality at https://youtu.be/v-qoZPKsLDs , by "Dave Rat", conclusions at the end at16:52. Electrically, the Cat.5 works best, about 50 to 100 % longer than the chosen "AES cable".

So, cat.5e, which is not broken, will carry DMX pretty well. But there is a big difference in how much mechanical stress difference cables designs can take from handling, coiling and regular daily abuse.

Awesome idea to used FTDI GPIO  to control LED strip such as  APA102 and WS2811
 
I’ve just find link form hackday that used FTDI capability to conquer disadvantages of Arduino speed & memory shortage then  control huge amount of LED  directly from PC with huge capability of software such as C#, I’ve just quoted from them
 

The FTDI cable can provide significantly higher throughput than using a microcontroller such as Arduino as a PC-to-pixel bridge, costs less, and by centralizing all code on the PC host. Using an Arduino as a PC-to-pixel bridge is limited to the maximum serial speed of 115,200 bits per second.  Each Total Control Lighting pixel must receive 32 bits of data, yielding a theoretical absolute upper refresh rate of 3,600 pixels per second (or 120 pixels at 30 Hz, and so forth). Using an FTDI adapter as the PC-to-pixel bridge, the data rate can in some cases push upwards of eight million bits per second.  The simple FTDI cable can transfer up to 45,000 pixels/second (or about 1,500 pixels at 30 Hz) while the full FTDI breakout board can manage up to 240,000 pixels/second (about 8,000 pixels at 30 Hz).  Actual throughput will vary with the number of pixel strands and the host computer's ability to render frames at these rates, but most modern PCs should be able to keep up with something close to those numbers.
 

 
I think if rich library such as FastLED revised is the way that could be used in C# platform , it can perform project such as high resolution(large matrix screen) online video rendering

That's pretty cool. +Hamid s k​​, Have you gotten a chance to try it out? I would imagine bus capacitance would be your killer for the higher data rates.

Come meet other people from the Open Lighting Project. We'll meet somewhere close to the convention center end of the strip and then go from there.
