Summary: Connect the LED Tea Light to an optical coupler to signal a MOSFET transistor to flicker and drive LED's or high current HB (High Brightness) LED's that produce a random candle illumination to light up your Christmas, Halloween or any display-device as you wish for fantastic results.
Making your own random circuitry by a microcontroller is time consuming and this method eliminates all the headaches for a simple and sweet project.
This method of produce a random flickering LED illuminated by means of a LED Tea Light can be applied to many things and devices for toys, miniature houses, train layouts, simulate fire/flames, Christmas lights, camping party lights, etc. Draw inspiration from the pictures and method to get your creative juices flowing in what you can do with this unique technique in LED lighting.
Step 1: LED Tea Lights and SnowFlakes
The snowflakes are manufactured by Kurt S. Adler, Inc part #H9069, SKU# 8613101472. The snowflakes are 1-3/4” long by 1” wide the LED will be installed in the middle of the snowflakes for illumination.
To make the snowflakes have more glitter I sprayed the snowflakes with White Krylon Paint and dusted on glitter to give it the best effect.
Please see the attached pictures for instructions.
Step 2: Modifying LED Tea Lights
Type two has a circuit board with the LED soldered in place and this is the best type to use. We will remove the soldered in LED and solder in wires to the optical coupler socket (Part# 4N35 to signal a MOSFET transistor. (On Semiconductor Part# MTP10N10EL) Please see the attached circuit diagram in PDF for all the instructions.
Step 3: LED's for Snowflakes
The 30Awg wire is 15ft long so I can hang the 10 LED snowflakes at different lengths on the fireplace mantel.Please see the attached pictures for instructions.
