Ow!Box!

Posted 2010.12.07 20.07 in Hobbies, Pointless Blather by Stephanie

What do you get when you mix electronics, boredom, a pinch of depression, and a warped sense of humour? Well, an Ow!Box! is one possibility…

Yes, it’s a fun-for-all-ages way to cause a little pain — without leaving any pesky scars or evidence. Just touch the two screwheads and crank up the juice. How long can you last? How much can you take?

Impress your friends, baffle your family, make it into a drinking game, or just wire up some chairs around the house.

The function is simple: Power from a 9v battery is run through a 555 timer chip to create DC pulses. These pulses are used to trigger a simple transister, which tweaks the primary winding of a step-up transformer. The secondary winding of the transformer is wired to the neon bulb as well as the touch contacts. A BNC port also allows the signal to be routed….elsewhere.

Put in a fresh battery, turn it on, and have fun!
