    An alternative for controlling 3W leds

    Your site gave me the inspiration to start my own little project Because my dome will only get used infrequently I've changed the fully automated system you've built to ease my build time. I'm going down the route of a dome with only seven 3W leds inside on a radial line from the bottom to the top of the dome. An arduino will control and synchronise the LEDs and triggering of a Canon 5D4 camera. The duration of the LEDs will be defined by the camera shutter by sending a signal from the camera back to the arduino so it turns the LED off when the shutter closes and the sequence moves on to the next LED. Once the first set of seven images are complete I'll manually rotate the dome 'x' degrees and shoot the next sequence. The dome is going to be mounted on a separate base so it is completely separated from the subject and the camera. Kev

    An alternative for controlling 3W leds

    The Keyes 3W modules seem to be very optimistic on power rating. They only pull 0.17A at 5.7V so loosely only 1W. Using a Colorchecker calibration and setting a white balance on a grey square they are also running at 8200k. I also have a box full of Bridgelux 6500k Daylight White 3W star pcb mounted LEDs. The LED board on the KEYES device is only two solder leads onto a star pcb and very simple to remove and replace with a Bridgelux module. The Bridgelux LCD is pulling 0.4A at 5.7v so 2.3W and is approximately one stop brighter and runs with a colour temperature of 6750K. I suspect the 5.7V value is probably a bit low as I'm using an commercial LED driver to power the LEDS and the voltage waveform is likely to have some ripple on it. The dome build will continue with the Bridgelux 6500K leds
  3. Hi, probably old news for the experienced Dome users but I've just found a link to a 3W LED mounted on a pcb which only requires power and one control pin. Rather than using MOSFETs etc etc a dome could be built using only one LED driver board with all the LEDS wired in parallel and a single control wire for each LED https://www.ebay.co.uk/itm/3W-High-Power-KEYES-LED-Module-With-PCB-Chassis-For-Arduino-STM32-AVR-UK/232870808490?ssPageName=STRK%3AMEBIDX%3AIT&var=532402693460&_trksid=p2057872.m2749.l2649 I've ordered a handful to have a play with Kev

    Embedding Rti viewer into Wordpress

    Thank you leszekp, that's exactly what I wanted I didn't consider putting another html page into an iframe but it works nicely http://www.photosbykev.co.uk/2018/08/22/rti-imaging-baby-steps/ regards Kev

    Embedding Rti viewer into Wordpress

    Searching the forums all of the options for viewing rti format images from within WordPress seems to have stalled years ago. I've just got the WebRtiviewer installed on my server and it works well on a static html page. Looking at the source code of the static page there are a number of links to things like spiderGL directories etc and then a simple container script to launch the rti file into the viewer. Has anyone had success porting this html code into a WordPress page? It doesn't look too difficult but I'm failing at the moment lol Regards Kev
