Introduction

Tuopeek is a collection of interesting items from electronic and physics. The website also contains some experiments they don't show at school! Often the best and most interesting science is also dangerous.  Some of the experiments require very high voltages and should only be attempted by people familiar with these. 

Note the warning on this Germicidal Ultraviolet lamp on the left. The lamp is made of quartz not glass. This allows harmful, short wave, Ultra Violet light to be transmitted.  For more like this see 'items'.

This lamp is manufactured like a fluorescent tube but without the coating. You can see one of the electrodes and the blue glow from the mercury vapour discharge. The filament electrode can be  seen clearly with the lamp switched off. 'Mouse-over' the image to see the alternative view.            ('Click on' the image for more on discharge lamps)

The glow discharge on the right is from a Helium-Neon laser. ('Click on' the image for more on this laser) 

Incandescent !

This early lamp (left) uses a carbon filament.  Carbon was the original choice material for light bulb filaments. The high temperatures required to glow white-hot resulted in early lamp failure due to filament evaporation. Carbon did not suffer too badly from this and was used until processes for using tungsten were developed. 

Light Emitting Diodes are becoming strong light sources. The close-up (10x) image shown on the right is of three LEDs in one package (tri-colour). The intensity of each LED can be adjusted to produce any colour including white.
