Some projects I've completed or are in progress.
These are mostly personal projects (ie. not directly connected formal education or work)

Built an adapter to power a desk lamp in a standard 12V automobile electrical system (5 October 2017)

Converted an off-the-shelf "zero gravity" chair to a comfortable computer chair (10 August 2017)

I've participated in distributed computing projects since May 2002.  After a recent computer upgrade, I restarted my participation in Folding@home (Pande Lab of Stanford University).  It does research in protein structures to understand how various serious diseases occur.  The name of my team is Agora_Aerospace (updated 11 November 2014).

Camera Monitor Shroud
Created a cover for a small video camera monitor to allow it to be used in blight sunlight (updated 18 June 2014).

Converting a cheap 2-channel RC airplane to a boat starting in March 2014 (updated 7 June 2014).

FreedomCam mount I designed and built in late 2013 (updated 15 April 2016).

No-Mess Kitty Litter Box
A kitty litter box I designed and built late 2013 to keep the cat litter inside the litter box rather than being tracked throughout the house (24 October 2013).

I've made many videos of different events since 2012

Chicken Feeder
I built an automatic chicken feeder for the chickens my roommate and I have from plans she found online in 2011.

Looks like a standard flight planner sheet. But, it calculates wind correction angle, ground speed, time en route for each leg, fuel consumption, etc.  Made around 2005.

This is a weight and balance spreadsheet that automates calculation for R22, R44, and 300C helicopters I made in 2005

Animated GIF
This is an animation I made back in 2001.  I don't remember the software I used (it was something I was able to download for free).  I just wanted to see if I could make an aminated GIF file.  It's very simple but, I really enjoyed getting it to work.  Please click on the picture below to see the animation.
