Hi George, Many thanks for your time to reply. I have the PIR Sensor HC-SR501 from ebay and it can be tuned to output a signal for the 10-15 second period I am looking for, the infra red range works perfect for my needs too. You are right, one LED connected straight to the output pin of the...

Perhaps all I need to do is link the HC-SR501 module up in a circuit up with a transistor, as per the video below.

Have found this cheap: Pyroelectric Infrared PIR Motion Sensor Detector Module HC-SR501 Am trying to understand if I would need to link up to a 555 timer circuit, or if it could drive a strip of LED's directly. http://www.mpja.com/download/31227sc.pdf...

Came across this video, 12V not battery powered but similar in principle.

Hi Fleck, Thanks for your reply. That is quite and interesting idea. I have seen this one below on amazon and will give it a try. I will test to see if it gives the desired lighting effect and motion detection when place inside the lid of the box.. even perhaps disassembling it and...

Currently building a model display cabinet!

For the LED lighting, perhaps this: LED Lighting Strips for 6V/12V (Self Adhesive & Ultra low Temperature) http://www.ebay.co.uk/itm/LED-Lighting-Strips-for-6V-12V-Self-Adhesive-Ultra-low-Temperature-/170882923791?pt=UK_Trains_Railway_Models&var=&hash=item27c96a7d0f Ronnie

Hello 555 timer community, I am making a clear display case for a model. I would like LED lights to activate when a viewer walks pass the display, and to stay on for a short amount of time say 10-15 secs. Display case size 400 x 400 x 400mm. I am hoping to make a very simple circuit using a...
