I've been enjoying using CAD programs and 3D printers to fabricate useful parts.  I plan on making this a bigger part of my professional life.  Here's a photo of the evolution of this product from it's last iteration as I print and test prototypes:

Today's shoot was in a beautiful Montana train yard.  Recording clean dialog here was a challenge.  One of the representatives from the rail company was kind enough to shut down the closest engine which reduced some of the noise.  I discovered that most of the noise came from the SIDES of the closest engines.  I worked with the team and we decided to go with a good looking shot from the front of the train, which put the loudest noise BEHIND our talent and their body provided a barrier between the noise and the microphone on their chest.  The boom still sounded the best, but the lav on their chest gave us the best dialog to noise ratio.

The visuals on these virtual production stages are pretty convincing.  When our talent first walked into the studio he thought our team had actually built a whole pirate ship set!

I participated in a 48 hour film festival this year, and this is the film we produced!

We all use them.  Those plastic blocks with a barrel connector that you plug into the wall that convert the high voltage AC power from your outlet into smaller AC or more commonly DC voltage for your electronics.  We also LOSE them all the time, or they get damaged or just stop working.  In this video Dave explains how to find the right power supply for your device.
