Trying out. Rotating beacon project.

Post by babyboy on Fri 14 Dec 2012 - 21:34

Am interested to do a rotating beacon project. This is my trial project. I'm not electronics train so all stuff will be off the shelf and help from bros here. Thanks to Werner in advance. So pls advice and give info or tips or whatever.... I will try my best. First off is the LED simulation beacon. I'm simulating this with Delight controller but is has some flaw..not enuf memory. Each LED is given a 20ma as there's a limit to the total MA the whole Unit can have.



Still trying out. I'm looking for flat base LED for this project... when to Sim Lim for a quick check with a basement shop which has lost of LED and gears... no luck. They dun have the LED that I wanted. I need to purchase a strip of LED, those 12V and desolder the LED myself... my god its so tiny. How to desolder and use. Better luck next time when I have more time to shop. Am trying to simulate it like the video...



This will be the optimum... but a far fecth for now. The inventor dun sell them.. the one on the left Shocked .. real rotating reflector.





Here's my first question.
If I set it at 40ma each output and put 2 LED in series... each LED will have 20ma?

You need to put 2 LEDs in parallel, not in series. Then each one will get 20mA -- given that they are the same type of LED of course. This is not ideal as due to tolerances one LED may get significantly more than the other.

But where is that 40mA number coming from? From the DELight Controller web site I can only see that it outputs whatever BEC voltage you are having, and you need a suitable resistor for the LED you are driving. Something like 150 ... 220 Ohms is fine for a single LED with 5-6V receiver power.

Desoldering light strips to get SMD LEDs is the way to go :-) If you need something more specific http://sg.element14.com/ and http://singapore.rs-online.com/web/ have all kind of SMD LEDs in many forms -- at a cost though.

Oh OK. To installed as parallel.

The mA is set at the programming software. Where you test your output (simple setup) before transfering the setup lighting to the Delight Controller. I bought the Delight starter Kit. Free software download (you can try). Simply set the brightness and the duration you want from the given table and coresponding stick control. The default was 100mA.

Hmm element14... yeah they do send me email of their product monthly. Thanks for the info.

You are back in action again! Smile

Interesting... looking forward to updates. Smile
