Polarizing Lens - OBSBOT

How I got rid of the glare on my glasses 

Zoom or Google Meet really point out the problem with glare on glasses.  Most solutions I found were rearrange the lights or tilt the monitor. I found on Amazon the real fix. Polarizing lens made for cellphones. A little rework and now I have a polarizing lens that works with my OBSBOT meet SE and 4K. This video shows how I did it. Hope it will help to cheer up the meetings.

Polarizing Filter for the LogiTech Brio500 Webcam 

I modified a cellphone polarizing filter to work with the LogiTech Brio 500 Webcam. A few hand tools, a drill and some assorted nuts and bolts did a great job of repurposing the polarizing filter. It removes from your glasses the reflections produced by your monitor.

Vacuum Packing
Cornmeal and Flour

How I Vacuum Seal Pack Cornmeal and Flour

This video show how I use a vacuum chamber and a vacuum pump to vacuum pack Cornmeal and Flour. This method is easier and faster than other methods of vacuum sealing jars. I do put the flour/cornmeal into a freezer for a few days and then let it warm up to room temperature before putting it into the jars.

Vacuum Packing
Oatmeal, Walnuts and Raisins

How I vacuum seal pack Oatmeal, Walnuts and Raisins

This video shows how I vacuum pack oatmeal, walnuts and raisins. I use a 3 gallon vacuum chamber with a vacuum pump. Being able to repurpose store bought jars of different sizes and types is very useful. Check the jars for a few days to make sure the lids sealed. Pickle, salsa and peanut butter jars all work great. If the jar came vacuum sealed from the store it can be resealed and used for other things.
