Robert Clotworthy was born October 24, 1955 in Los Angeles, California. He was named after his uncle, Bob Clotworthy, who won the 1956 Gold Medal, at the Olympic Games in Melbourne, for Spring Board Diving. He began voice acting at the age of 15, his father was a producer of radio commercials. Robert would tag along with him to work and met some of the greatest such as Jerry Stiller, Anne Meara, Mel Blanc and June Foray.

I wanted to place my bedroom TV fairly close to my bed. To do this, it would have to be placed on a wall to the side of the bed. This meant angling the TV so that while lying down the screen would be square to my vision. I had a Best Buy gift card so I went on a hunt. I found the perfect wall mount and tried it, in the store, with their demo.

The video below shows a speed comparison of spacecraft and spaceships from TV series, Movies, Games, and NASA, which means all real and fictional spaceships.

This is the full length video of a guy that has a lot of extra time and designed a squirrel obstacle course because they were defeating his “squirrel proof” bird feeders. I love all the science and technology involved and the guy is hilarious, even naming all the squirrels.

This is a fictional starship size comparison video. These are from video games, TV and movies. Enjoy!

Here is a interactive brute force search space calculator that allows you to see how well you have secured your site with your password. It is fun to try easy ones and then what you need to do to strengthen the passwords you come up with. This was written by security expert Steve Gibson and is perfectly safe.

If you use Facebook you have seen a post, usually fairly long, that instructs you to copy and paste this post into your own status. Older people, like me, will remember chain letters that try to convince you that you’ll have bad luck if you don’t mail copies of that said letter to some number of folks. This is sort of the same thing. While every post with copy and paste instructions, on Facebook, is not a hoax or scam it is the popular phrase used in both.

This is a collection of old video shorts, reminding me of the kind of 1960’s films they would show us in school. They come from the time where computers were the size of rooms, buildings, not something we carry around in our pockets every day.

Back in the Citizen Band (CB) radio days (mid 70’s) I had an Antenna Specialists Starduster. I installed it on a 20 foot galvanized pole from the peak of my family home in Alpharetta, Georgia. This put the top of the antenna at 40 feet. I don’t remember where I purchased the Starduster but the poles, mounts, ground wire, coaxial cable and guy wires all came from the Roswell, Georgia Radio Shack. I ran the coax down the side of the chimney, into the crawl space, and then back up through the floor of my bedroom. This was one of the most popular antennas of the 1970’s, omni-directional with a 1/4 wave ground plane and 9 foot diameter. They claimed it had a 5 db gain, which is doubted by most, but the antenna worked well and was highly regarded in the CB world around me.
