Complete kit of all the parts you’ll need to build a Doom button.

Category: . Tags: , , , , .


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 minutes to assemble and includes an IN-1 nixie tube, USB lead, suitable UK plug mains to 5V adapter and phenolic laminate case parts.
