An LTSpice screencast using screentoaster.com

I was trying to remember how I did screencasts before, but instead discovered the interesting online service at screentoaster.com. It doesn’t require that you download any software: you can quickly record what occurs on the screen and upload it either to youtube.com or their own server, and then embed in a blog post. Here is my first attempt: demonstrating a simple astable multivibrator circuit that I cribbed from Hans Summers’ low powered QRSS beacon project. Using LTSpice, you can easily reproduce the schematic and then find out how it varies the voltage and current.


This is really just a test, I hope to have some more interesting circuit examples in the not too distant future.
