I visited Carrizo Plain National Monument, a remote valley in California, this past weekend to see the current wildflower show. Unlike last month when I was there, there are now flowers covering the valley

Hello all - it's been awhile since I last posted. Let's get to it. Sitting on my desk for the past month is a small battery powered FM transmitter sold by Straight Talk, the cell phone carrier. The device

Recently I completed a small project - I created a little X-ray radiation source using a barbecue lighter and a vacuum tube. When you pull the trigger, a short pulse of X-rays is produced inside the tube.

I finally licensed my drone so I can use the photos for "commercial" (Steemit) purposes now. Here's a shot of Harmony Headlands, a state park north of Cayucos, from last week. It's the tail end

Early this morning, the Insight mission launched aboard an Atlas 5 rocket on a trajectory to the planet Mars. This large machine, weighing almost a ton at takeoff, will touch down on the red planet about

For some reason my local dollar store had a ton of different types of fitness tracker devices today, all for $1.99. I decided to buy one to see what's inside. One in particular stood out for having Bluetooth,

This picture is of the rocky northern side of Morro Rock, a volcanic plug on the California coast I often visit. The cliffs on the right rise up several hundred feet. The rocks are black because they are

I've finally got another technical post today. My schedule got extremely busy in the last week but it's finally getting better with finals being this week (my courseload was such that the week before finals
