Japan Day 5, Tokyo

This post is the fifth in a series of nine illustrating my trip to Japan. On my fifth day in Japan, March 25th, Matt and I decided to take the time to do some sightseeing and go to the various areas around Tokyo, including Central Tokyo (東京), Ginza (銀座), Asakusa (浅草), and Shinjuku (新宿区).

Japan Day 3, WHC’07, Matt’s Presentation

This post is the third in a series of nine illustrating my trip to Japan. On the third day, March 23rd, I presented the paper I co-authored, “Frequency analysis of the detectability of virtual haptic gratings.”  It was surprisingly stressful (this was my first “real” presentation to a group of >200 individuals), but it went over well.  Matt also presented poster on a paper he co-wrote, “Discriminability of Real and Virtual Surfaces with Triangular Gratings,” which is shown in the images below.


Back from Japan

It’s been a while since I’ve posted and that has been primarily due to the fact that I had been preparing for an oral presentation at the World Haptics 2007 conference. I presented a paper this past week on research that I had conducted with Dr. Hong Z. Tan at the Haptic Interface Research Laboratory investigating whether a linear system model can be used to describe human texture perception. Our research supports the hypothesis that the human somatosensory system may perform a spectral analysis on the proximal stimuli and that a linear system model may describe human texture perception.

Pseudo wide-angle temple shot

I had the opportunity to present our research and to take some time to travel to Tokyo (with my friend Matt Kocsis) and Kyoto. I’m going to get back into the swing of things and start posting more projects (I’ve got a couple up my sleeve that some people might find interesting). I’m also going to post some galleries of pictures from my travels.

Website Host Transfer Complete + Sparks

I’ve completed the server move and the DNS changes, so hopefully everything will now work. There was a problem with the email program (cgiemail) during the transfer, but it seems as though I resolved the problem by using a different script (FormMail). Please feel free to send me an email or leave a comment in this post if there are any problems.

High Voltage Sparks Over and Through Red LED 2/3

As an added bonus, I’ve attached some pictures of sparks generated with my high voltage power supply, which I was able to fix. It appears as though the old MOSFET had blown, so I was able to recreate the circuit with no issues. Continue to the post for a few more pictures. Read More

Changing Website Hosts

For the past two years I’ve hosted my website using QualityHostOnline and the traffic to my website and bandwidth usage has steadily increased every month. I’m very happy about this, but unfortunately this month I’m afraid I might go over my alloted bandwidth of 2 GB.

I’ve decided to change my website hosting to a higher bandwidth host (AN Hosting) as a long term solution. Hopefully there won’t be any issues, but please let me know if there are!  I highly recommend QualityHostOnline as a very affordable host for small websites needing <2 GB of bandwidth each month; I’ve never had any serious problems that have not been solved by their support staff within 24 hours.  I’ll let you know how AN Hosting turns out.
