Dave gives the solution to the first hardware quiz.
How do you design an LCR meter?
What about a stepped transmission line attenuation tester?
What does modular design and management have in common?

Is it possible to get the self resonant frequency out of Rs and Xs?
I would be a VERY Drunk man to play the Dave Jones "Basically" drinking game…
sounds like some of your viewers are really smart.
In Dubai!
I compared your formulas with mine and noticed a small mistake in the formulas at 3:27:
XS = imag( V / I ) = ( Vq*Ip – Vp*Iq ) / ( Ip^2 + Iq^2 )
(Just a – instead of a + in the numerator)
BTW – I made my own LCR meter based on this measurement principle 🙂
hey dave, where can i find more information about this method?
@Bushougoma Yes, it's an old video from the old video camera that did not have an anti-flicker mode.
Wow nice! I made an impedance tester for my senior project… came up with the same equations. I used a Cypress PSoC3 (used DMA to send sinusoidal LUT to DDS DAC, filtered it, mixed the voltage and current with a reference digital clock, then LPF'd and did floating-point calculations all on a single chip). Got it working an hour before the presentation was due.
I've been an infrequent visitor to your vlog, but it seems I'll be coming back more often =)
cool & interesting video, keep it up mate!
