Read all the warnings, don’t do this unless you know what you’re doing… And if you know what you’re doing you won’t want to do this –
The tingle-tron was the result of a discussion between electricians about the effects of various levels of current through the body. Being electricians we are no strangers to the odd electric shock now and then, so for fun we decided to see what sort of current could be handled comfortably. The unit was built and then used on everyone in the team to ascertain who could handle the most current. Obviously for macho reasons we all eventually took it to the “max” (8mA) despite it being a rather intense experience! (4mA was quite nice though)
Current flow through a human body has an effect that is proportional to the level of current flowing, and the area of flesh it is flowing through. This means that for a specific current a larger person will get less of a shock than a smaller person. In general a current range of 1mA to 8mA is detectable as a tingling that affects a single finger at 1mA to most of an arm at 8mA.
Although the level of current required to cause adverse effects in an average adult is 30mA (where the diaphram contracts and prevents breathing), the current limit I chose for this circuit is 8mA which should pose a low hazard while providing plenty of tingle-tastic fun (or pain!).
