Dash cam video of head-on collision. 20200608.
There is less than a second between the car being visible and the crash. Note the image shift down when I hit the brakes. I slowed the crash down to 9.99% speed.
The audio is Leonard French playing at 1.5x speed.

Sanitize your mail with Ultraviolet light.
Worked example on how to calculate power output and exposure time for a 20 watt off the shelf germicidal ultraviolet medium pressure mercury lamp.

I invite all to check my sources and calculation.








Calculation in the video
Matching wavelength output by spectrum.
UVC output power is 15% electrical input power.
milliJoules per square centimeter from Watt seconds per square centimeter.
Exposure time based on UVC Fluence divided by watt seconds/suare centimeter power output of light.

Enjoy the relaxing sights and sounds as we hike through Old Man's Cave Gorge trail. The hike follows the creek from the upper falls to Old Mans Cave.
Old Man's cave is located in Hocking Hills State Park, Logan, OH 43138.

The Intel realsense tracking camera T265 will automatically transform the depth camera point cloud. This might be the basis for a real time 3D scanner.

Step by step process I use when making raspberry jam.

It follows the recipe provided with Sure Jell and Certo pectin
6 1/2 cups of sugar
1/2 tsp of butter
1 package of pectin
8 cups of un-crushed raspberries.

Mix the sugar, butter and crushed raspberries in a 4 quart pot.
Bring to a rolling boil for 1 minute.
Add the pectin.
Bring back to a rolling boil for one minute.
Remove from heat and ladle into jars.
Clean the threads and cap the jars.
Let jars cool at room temperature.

Just some of the sights to see at the Field Museum, Chicago Illinois.
There is a great dinosaur exhibit in the Evolving Planet display. Not to mention they have Sue the most complete T-Rex, and a titanosaur, AND Antarctic dinos, with artifacts from the ill fated Terra Nova expedition.

But there is so much more, I just put the highlights in this video.

This is my coffee roasting process.
I built a drum roaster from a stainless steel utensil bucket and a Wagner heat gun. Most of the parts are from Home Depot, except the drum. The drum is from one of the kitchen themed stores.

It works pretty good, but there is a lot of chaff when the roasting is done. If you have any ideas on how to eliminate the chaff please comment below.

Looking to document my projects and ideas. My day job requires the use of light and cold statistics to reveal flaws in factory made products. I hope to reverse that mental flow by using light to enhance beauty and the channel to share creative ideas.
