Hi everyone,

I did some progress on the Version 3 prototype, it has more working function then before. I am still facing with some hardware butg, what I inherit from the Version 2. I found out the original circuit has big issues, because I did not had Oscilloscope when I developed the Vesion 2 I could not see these issues before. The Voltage ranges was messed up. Most of the issues I could fix, but it has still some.

A little bit about the spec:

• 6 Voltage range (6 Current range)
• 6 Frequency range

And the video:
