Its just that I recently saw this quote around the internet: "About 25 species of venomous (poisonous) snakes are native to the United States" and I got to wondering (as anyone would) about old barns that no one has set foot in since 1982, etc...

It is a mosquito trap and the fan sucks mosquitoes attracted by a chemical compound, heat and UV light. The fan must not stop or the mosquitoes will escape.   I forgot to mention it is a Jata MT8.

The inverter ran for several months with a blown bulb so it has no problem to run without a load. But can it be damaged if the bulb is disconnected while powered?     Is there room to add a supply just to power the fan? If so, you can arrange to power down the CFL inverter (even directly at the processing chip which usually has an enable line) when not needed instead of suddenly disconnecting the load. This way, you would probably not even need the relay; use your photocell and transistor to shut down the inverter directly.   I don't know if mechanically switching your lamp on and off will damage the lamp or supply, but my gut instinct is no.   Switching power at the processor IC will be safe for both.

tubeguy@myshop.com: Mar 17 12:21AM -0500 I've learned over the years that water destroys all LCD screens. Several years ago, I had a pipe break in my house. Did considerable damage to the house and other stuff, but it soaked a police scanner and a AM FM radio nearby. The radio had an analog dial. I dried it well, and it worked fine. I dried the scanner too. The scanner turned on, but the LCD screen was dead. That rendered the scanner useless. Aside from that, the speaker was shot. Replacing the speaker was minor, but even if I could find a replacement LCD, I am sure it would have been costly and difficult to replace.   Eventually I found an identical scanner on ebay for probably less than what a replacement LCD would have cost me.   I lost a cellphone outdoors. Weeks later I found it, after several rain storms. The same with that. The LCD screen was dead. The phone appeared to work, (made sounds), but without the screen it was useless.   I had a similar experience with a GPS, which got soaked.   Why dont they put some silicone sealer on the edges of those LCD screens? Or something that will prevent water from getting into them?

I don't think that's true. Why, just the other day I was brushing my teeth with striped toothpaste after eating some some hard candy discs that had a valentine heart shape that went clean through the candy and it got me to thinking about multi core solder and how they make the stuff. So there. Eric

So there. > Eric   AFAIK the two usual methods for that sort of job are co-extrusion (as in Blackpool Rock candy sticks, where the writing went all the way through from one end to the other) and drawing down a preform through a succession of wire dies. For solder, drawing down would be my guess.   Cheers   Phil Hobbs   -- Dr Philip C D Hobbs Principal Consultant ElectroOptical Innovations LLC / Hobbs ElectroOptics Optics, Electro-optics, Photonics, Analog Electronics Briarcliff Manor NY 10510   http://electrooptical.net http://hobbs-eo.com

I once asked a baker how they do it, and he said it's injected with a device similar to a syringe. A plastic point is shoved into the donut and the jelly injected.   A large object like a donut or candy seems a lot more easy than that thin solder.
