Set me thinking though, I have a reel of white smd Led's bought for a job that never happened.

Maybe this thread would be useful ?

I have just made and installed a control panel for a glass blower friend. The labels for the modules are fibreglass circuit board. If you put LEDs behind them the lettering shines though beautifully. Next phase of project ??? I might even go full steampunk. maroon and green with gold striping and ornate Ibis carvings in the blank areas of the panels and , of course I would have to change the stainless metric button head screws to whitworth bronze slothead.


The picture btw is a screenshot of an IP camera set up to view the panel from anywhere.

Nice work on the furnace control, just for those still not disillusioned with LEDs have a look at http://www.onsemi.com/pub_link/Colla...I45020JZ-D.PDF http://www.onsemi.com/pub_link/Colla...SI45030A-D.PDF and there are versions of this with different current and voltages
I'm still trying to work out how to use a illuminated led as a switch if any one has done this let me know

What ? do you mean with an LDR or something ?

I think you might mean as a touch switch - I presume you could use a metal cased led on an insulating panel as the sensor on a touch switch circuit
