Back from the Melbourne trip, and the kids (and Dog) are glad we are home. A big thanks to John for organising dinner and sweets, and Tim for showing us some great new things he has been working on. My ATTINY programmer has arrived, but I am yet to find time to work on programming it, but I hope to sit down and work on it next week.
I have managed to complete 6 LED Floodlights, and 2 more are waiting to be installed in their case and be tested for the usual 4 to 8hrs on. I have noticed that the LED's get to 50C when run for more than an hr or so, and the back of the LED board sits up around 75C. I guess a few of the 13 or so Watts have to be converted to heat, so it gets rather toasty in there.

This is the rear of the LED board, with the DC SSR bolted to one corner, and cabletied in place. A piece of plastic sits between the boards as an insulation layer between them. Only 3 channels are built, as there is no real need to waste the parts for an unused 4th Channel.

This is the front of the floodlight. The 4 corners have small bolts through the board, and anchored with 5 minute araldite to a point on the glass which has been roughened pretty severely with a dremmel and stone tool. The rest of the glass is lightly sanded with wet & dry sandpaper so the scratches disperse and soften the light, giving a better white color when all 3 colors are on.

Because of the poor interior color and the need to seal the original holes, araldite is used to plug the old holes, and also seal around the 2 new holes. The interior is painted with a silver color paint, and then given a couple of coats of clear laquer. The rubber seal at the front, missing in this shot, is then glued in place.

Here are 6 of the 10 floods required for the year completed, and ready to deploy later this year. Each one has been tested for a minimum of 6hrs, but some have been run for a fair bit longer. Parts have been ordered to put a small rectifier and cap in each of the 14 planned lights.
