Lynx Smart String / Need some updates
« on: June 16, 2013, 12:40:29 pm »
Ive been off the forum for a while now, haven't had the time or money to-do anything very exciting when it comes to leds and lighting. However I'm back just now and I have seen this dumb string controller, I want to make RGB LED tubes, are the dumb string controllers DMX controlable? From what I have read they aren't which is ashame as most of my other kit is DMX but cant me converted to the new kind of protocol (kind remember the name of it just now)

Cheers

It is really just so I could run 2 of the convertors which are set to start on channel 1 but run them on different start channels but the same universe. So the first convertor could run fine as it starts on channel 1 but the 2nd might start on channel 60 so it would really be a device that starts listening at a set channel lets say 60 and then outputs that as channel 1 so the convertor see's it as channel 1 if that makes any sense

Hi, Ive recently been looking at this website You are not allowed to view links. Register or Login. I like the idea of using these cheap protocol convertors, however they all use start channel 1. I cant write PIC code, I'm a VB guy. But is it possible to write code and make a device that lets say is programmed to start address 32, then outputs channel 32> as starting channel 1? So the protocol convertor sees channel 1 but its actually channel 32?

I have attached a drawing of what I was thinking if it helps.

I have this on the Ren4Flood if you are interested.

Do you have a link to info on the Ren4Flood? I had a look about the DIYC wiki but couldnt see anything about it

Thanks for all your info, I through together a breadboard using a PIC16F688 and the DMX code and so far its all working. I still need to fully test my DMX pass but in theory it should work.

Bobcat DMX Servo Controller / Re: Set DMX address as 0?
« on: December 28, 2011, 02:02:55 pm »
It was really just to save channels and make it easier to understand in my head since I have a bad habbit of forgetting about blank channels when setting up and then spending hours troubleshooting why I cant get it to work.

And as for the solution from n1ist, I have no idea why I didnt think of that before haha.

Bobcat DMX Servo Controller / Set DMX address as 0?
« on: December 28, 2011, 08:47:35 am »
If I wanted to use only 3 servo channels and 4 LED channels, is there a way to hide the other channels if that makes sense so that I dont have 5 Servo channels and 4 LED channels sitting in my sequence empty? Its for a moving head, my plan is 1 servo bottom to make it spin left and right and 1 servo each side of the light to make it easier on the servo's to move it up and down. So servos 2 & 3 would both be on the same channel. So it would be 6 channels per light (Left Right / UP Down / RGB+W) I would use some high power leds and mount it in a custom perspex box.

I just was wondering if there was a way to hide the unused channels so I'm not wasting channels and it makes it easier for sequencing and stuff.

Other Projects / Custom Channel Number
« on: December 28, 2011, 07:01:01 am »
Hi, I was wondering if someone could tell me how easy this would be to pull off. I have lots of different custom made lights, some are 3 Channel RGB, some are 4 Channel RGB+A, some are 5 channel, RGB+White+UV and some are 6 Channel Strings RGB+RGB. How easy would it be to have a controller for each of these lights and not waste channels? Because just now I'm using a ren48lsd with DMX firmware running these and while it works it means everything has to run back to the same place and I cant use the RJ45 ports are they waste channels in some area's or cant support enough channels per port.

So really what I'm looking for is a schematic and some firmware that I can modify each time to suit each controllers need. So maybe for example using a Ren48LSD design but have the pic only read the channel I specify because the DMX code for that pic eats the channels if that makes sense. I dont mind if the PIC could support 8 channels, but I only want the firmware to listen to the first 4 channels if that makes sense.

I'm really just after a seperate controller for each fixture that I can program to only listen to a set number of channels. Just brainstorming outloud here but maybe something like an 8 channel DMX board that you can program the firmware and tell it that its Start Address is 12 and its end address is 15. But I could change that if I changed the light so it could then support channel 21 to channel 25 if that all makes sense. Also if the firmware didnt eat the channel when it used it that would be great so no matter what order I plug my controllers in they always react to the channel I assigned them, if that makes sense.

Any ideas would be great or links or things to read, I have no expereince in programming pics but I'm not affraid to learn haha.

Lynx Aether / Re: How it works?
« on: December 27, 2011, 06:22:11 am »
So am I right in thinking that the 2ohm resistor sets the output voltage of Voltage Regulator (LM2941)? And the LED just takes the current it requires? Or does the 2ohm resistor set the output current of the Voltage Regulator (LM2941).

Thanks :)

Lynx Aether / How it works?
« on: December 25, 2011, 06:40:21 am »
Hi, I was wondering if someone could help explain to me how the Aether works, I know it takes the 12VAC converts it to DC and then a pic converts the DMX signal into electrical signals but the bit I'm confused with is the controlling of the LED. Ive only ever worked with 5mm leds so I use resistors but how does it work with high power leds? I want to build different light fittings using high power leds but I have no idea how to power the led.

Thanks
Stephen

Merry Christmas

Lynx Express / Change of triac, is there enough current?
« on: December 17, 2011, 10:18:47 am »
If I changed to triacs to something that needed 50ma each would the board be able to handle that or would I need to change other parts? I know the optocoupler is fine upto 100ma, but would the rectifier and the transformer be able to handle it. The triacs used on the board pull 10ma so there is a 40ma difference so there is a 640ma difference? Is there enough headroom for this?

Cheers Steve

Lynx USB DMX Dongle / Re: Lynx Dongle to DMX 5 pin

Okay that's fine just out of interest since I didn't realise about all of this, is it a legal contract I'm in with yourself?

If I wanted to power something like 3 of these from a 12V DC supply, what kind of circuit should I be looking at? I can do LED's when its just resistors but I just cant work my head around the high power stuff

Do you still have 3? And if yes how much in total to send to the UK?

Thanks

« on: November 23, 2011, 02:50:44 pm »
Thats fine :) I cant remember what the transistors are rated at but I can find out :) I was wondering is there another more efficent way of powering high power leds? I was thinking if I had say 10 3W leds thats going to be alot of heat coming from the resistors and I was wondering if there was a more efficent way of dimming or if that was it?
