The Venus Frequency.
This may get a little bit long and technical, but bear with me.

As I have mentioned before, I'm a mechanical engineer. As such I like to build things. This is the story of building a unique sex toy.

It all started with jokes about the Brown Note as referenced in South Park. The theory is that a particular frequency will cause resonance in the abdomen, causing a person to lose bowel and bladder control. But then I started to wonder about this- maybe there was another application of the concept?

There are plenty of anecdotes about women having spontaneous orgasms while riding motorcycles or sitting on top of a clothes washer during the spin cycle. So with this in mind a friend of mine and I undertook an experiment in his workshop, where he has all sorts of metalworking equipment.

We got an old fiberglass stacking chair like this one and took the seat off of the base. We built a new base from a piece of 3" steel pipe and a couple of square steel plates, added some rubber grommets to it and bolted it on top. We put four stiff coil springs under it for feet.

Then we went to the dump and scavenged a motor from a clothes washer. To the side of the pulley wheel we welded a chunk of steel that weighed about a pound or two, then attached the motor to the side of the steel pipe base. We ran the power for it through a fairly heavy rheostat and gave it enough cord that a person sitting in the chair could hold the control and adjust the speed.

My girlfriend at the time was our first test subject. She sat down in it and turned it on low speed, then gradually turned it up. After a minute or so her eyes got wide, her breath started to come in ragged gasps and she let out a sound I knew well. When she finally turned it off she could barely walk.

My friend's girlfriend took a turn on it next. From what he said it was surprising that she didn't leave her fingerprints in the arms of the damn thing.

After that my friend's workshop became a very popular place (it was too heavy to carry elsewhere, and a bit too noisy besides). We had no shortage of test subjects, and ultimately concluded that around 1800 rpm was optimal. We had found our Venus Frequency.

After a time, though, the fiberglass chair began to crack from the vibrations, so I abandoned the concept and he said he would dispose of it- it was starting to smell a bit by then anyway.

I don't know for sure what he did with it, but I do know that his wife always seems happy these days...
