On Oct 25th I had a home open day. This year I got a few more people (about 70-80) (probably the free beer).
I had about 50 displays of my stuff with the highlight being the big TC. A lot of my HV stuff was on show.
I was assisted by 4 people from the University Physics Dept who came 200 km from Perth and helped out with the liquid nitrogen and ferrofluid displays.

The first photo below shows that geeks and women aren't mutually repulsive (it lasted 5 seconds before they ran away). The technique was to have everyone on place with lights out and TC off. Then the camera flashes but keeps exposing for 5 seconds while everyone runs away and I run to turn the TC on briefly to capture the sparks as well. Most of the people there had their photo taken under a firing TC in this way.

thats really cool!
The top picture would look real (as in same time) if part of the ladder wasnt invisable =)
How did that even happen?

Those are some real crisp photos, Peter -- I love how you capture the night scenes without the frame filling full of thermal noise.

The digital SLR has a lot more light pickup than a digicam due to the bigger lenses. (thats my technical explanation). It makes a real difference to be able to take comfortable long exposures like up to 3 mins for some Tesla shots like the Xmas tree.

All the other photos were ok because no-one had the hand over the ladder when it got some reflected light from the spark rather than the camera flash. Last year I had a bit too much ambient light and peoples legs were a bit see through!
I need enough ambient light to be able to see that people have run away from the TC before I fire it. With the first volunteer, I looked at the flash by mistake so couldn't see enough to safely fire up.

You should post more publically the photo that PROVES that Tesla Coils make human bodies transparent ;)

A million new-age hits per hour!

Looks like fun, I recognize lot's of stuff from your website. Public awareness like this is a good idea, it gives people the right impression of what science at home is all about.

I had 50 projects on show in some form and there are roughly 200 on my site. My wife spent ages laminating edited segments of my website for labels.
Public awareness is fine (just not the Dept of Energy Safety in Australia) so it is still low -key and just for "friends". Remarkably, nothing was broken even with the number of children around.
I am not really sure that my place is what science at home is all about. There is a fair bit of "Don't do this at home" stuff that I do. Good clean fun and a real experience for a range of people from kids up to physics/electronics technophiles.

Once the Google bots hit 4HV the they will pick up your post, be completely misinterpreted by the New-age'ers and the fun will begin

Lovely event TDU

Its a heartwarming feeling to show and tell other people about the experiements that takes a great deal of ones time :) Unfortunately you are half way around the world so I couldnt make it ;)

the webcrawlers can even look at pages that to the user could appear password protected if the server is not set up properly / bad code.

Very nice!

You are definitely the premiere mad scientist in the entire world. You got my vote!
