A nixie tube based ‘plasma globe’ toy that glows in response to anything conductive touching the outer glass.
The main feature though is when touched it will operate a low-voltage relay for about a second which can be used to interface to your own project or connect to a PC motherboard to switch a computer on/off. Activating your missile launch sequence is also possible but not recommended.
Supplied as a kit of all parts required, it will take most constructors around 30-60 minutes to assemble and includes an IN-1 nixie tube, USB lead, suitable UK plug mains to 5V adapter and phenolic laminate case parts.
Complete PCB assembly, case part sanding and polishing skills required. You can find the assembly instructions at http://www.lasermad.com/forums/viewforum.php?f=16
