KF5OBS #48: Guitar Tone Adjustment Circuit

Quick video for a new weekly format called “Circuit Friday.” Circuit Friday will present simple but useful circuits that can be built in an hour or less. I’ll try to keep the difficulty on a beginner level. This first circuit is a single pot tone adjustment circuit. I’m using it for my guitar but it can be used in various different applications. Such as an adjustable tone control

 

KF5OBS #47: Multi Camera test

Quick experiment to develop a workflow for multi-camera episodes. I’m happy with teh test results though I have a lot to do and consider. Such as white balance and color grading to give the footage a consistent look and feel. I also need to play more with multi-camera sequences in Adobe Premiere. It’s pretty straight-forward but has some hidden traps.

In this episode I’m showing the intense resolution of the Keithley DMM 7510, a 7 1/2 digit bench multimeter. It’s giving unbelievable microamp resolution on a milliamp scale. That’s just nuts. In a good way.

 

Hands-On Spectrum Analyzer Workshop


Tektronix is offering some kick-ass hands-on spectrum analyzer workshops across the United States. I’m excited to announce that I will be at the Santa Clara RF Signal Hunting and Transceiver Test workshops on Tuesday, May 19, 2015. Be there or be square!

KF5OBS #45: Instrument Landing System Testing

This video shows how easy it is to test an Instrument Landing System, ILS for short, receiver for localizer and glideslope accuracy.

This video was shot in DNxHD using the Blackmagic HyperDeck shuttle I showed in another video (https://www.youtube.com/watch?v=cc83-Cc-vtw). After editing in Adobe Premiere and finishing it off in SpeedGrade, I exported it to h.264 at a variable bitrate averaging 35 Mbps. Please let me know if you see an increase in image quality.
