Wireless DMX retro fit of my fixtures!

I've always wondered about that - they do go through a lot more walls than my Wifi. I hit their limits the other week though when I used a few wireless pars at home for Halloween. They can't get through a double skin brick wall, two thick breezeblock walls and a further single skin brick wall over a distance of about 40ft. My home Wifi router can't get through half that.

To save on antenna's I've been using some of my fixtures with stubby antennas (4.5cm?) because I kept breaking off the 9cm antenna's they're shipped with and I've yet to have one drop out on me.

Where do you get the stubbies

eBay - straight from China :D

Be careful of the gender of the connectors - it seems that the majority of Wifi Antenna's are female, the PCB's come with a male tail.

All the ones I've seen with the dmx boards have female SMA tails & the supplied antennae are SMA male. Uk sellers are charging £4.99 for stubby 2.4ghz right angle aerials :eek:

Yup, you're right - they are. Sorry, my bad.

It's good to be careful what you're buying though - you're right that male & female (and reverse versions of same) available.

In other news, I've now replaced TWO dud Chinese boards in as many weeks - they've lasted about a year inside fixtures. Not mine though..

That's interesting, I've yet to have one fail (touch wood) after 5 years with about 30 of the things in various versions from various different sources.

I've had boards be dead out of the box. One of the replacements for a faulty pcb had no connections to the dmx pins on the white connector. Another looked like it'd just had components sprinkled on it. Methinks there's a lot of sub par clones kicking around these days.

One of the ones that died the micro onboard isn't running & the other the radio gear just gets very hot.

I'm currently working on a system to replace all my wireless boards with diy wifi artnet to dmx nodes. More on that story later!

i am looking at getting this Laser fitted with some form of wireless function. Does anyone have any recommendations on where to tap the 5 volt from? I am guessing that the LCD panel, fan and maybe the SD card port may have some form of low level power? I thought it had a USB port, but it has not. I shalt take it apart next week and dust off the multimeter.

Anyone got any DMX boards going spare too??

Thanks

Pictures. Seems to be an abundance of 12 volt supplies for the fans and such like, but nothing less.
I dont really want to be messing too much about with it, unless I am sure. :)
