Lamp
OK I realise that this question is not strictly woodwork related, however, it may have some applications for projects for the future.
I have a lamp ( purchased quite cheaply from K-Mart) which appears to be made from some form of ceramic material. When you touch the base of the lamp with your fingers ( or toes, or other body parts presumably ) the lamp turns on. If you touch it again the light gets brighter. Touch it one more time and the light gets very bright. One further time and the light goes out.
My question - and I do have one - is how does this work (be aware that I have a deep and morbid fear of all things electrical and advanced electronic theory makes my eyes glaze over, so I need a simple explanation) and is it possible to buy the dohicky that makes this possible. Could such a dohicky be incorporated into a wooden lamp without a lot of trouble?
Thanks in advance for any info.
Cheers

Just so happens that David Tulloch at The Turnery has just started marketing these lamps in a kit form for woodturners. You get the base the centre bit (looks like hollow allthread) all of the wiring pre-done bar attaching the top bit to the wires (2 screws) and they work real good and are pretty well the right price.
All you have to do is bore a hole down the middle of a lump of wood, turn the shape, put on some Shellawax, assemble and Bobs yer uncle.
It is as simple as that. They look great, work well and are cheap enough that you could flog em at a market for a very tidy profit, and still be selling at a reasonable price.

Hope this is of some help.

Dick Smith Funway to electronics volume 2.
There is a project in there that uses the principal.
Every body has some electricity held in the body's cells and this unit discharges a wee bit more into the body causing the circut to change mode and activate a further circut that does the work.
Same with elevator touch switches...try touching with plastic - nuffin. gotta be conductive.

Thanks to all those who responded to my question. I have checked out The Turnery site and have asked for details regarding cost and shipping. However, the picture displayed on the site is of a brass based lamp - Even I, an electronic moron, knows that metal conducts electricity so, at some level, I can understand how this lamp works. The lamp I have at home appears to be of some form of ceramic material. Isn't ceramic used as an insulator against electricity? Is the coating used on the lamp the conductor or is the ceramic material itself the conductor? Again, thanks in advance for any help.
Cheers

Westie.
Without actually looking at what you have it's going to be difficult to say.
While my Electrics theory is over 20 years old, Ceramic is definitely not a conductor.
More than likely you probably have some sort of foil impregnated on the surface or a wire which is cleverly hidden level with the surface of the ceramic base.
Or possibly they may have some sort of proximitry sensor within the base, ie a coil which when a hand is place close or next to it, the inductance changes and the electronics do the rest, (just like a metal detector) But then again it may work of capacitance in some way.
These sorts of things may work similarly to some of the old touch tune T.V's
What’s the name of the outlet you purchased it from coz if I get the time I'll try to drop in and have a look.
And if anybody thinks all the above is total bull , It won’t bother me.
Hope this has been of some help.
Regards
Gino
