MEP EP#225: Clipping and Clamping OpAmpsStephen
DC heaters continued
Tested the new values
Last episode was shooting for ~250mW of dissipation in the regulator and transistor
Measuring closer to 350mW
Quiescent current and some balancing and tolerance
Opamp clamping circuit
A useful voltage clamping circuit with independent upper and lower thresholds
Pros
Much more accurate than the simple clipping circuits
Hard turn on characteristics
Can be overdriven without much issues
Not terribly expensive
Downsides
3 or 4 opamps needed
Not particularly fast - starts to show issues past 20k and is pretty bad at 30k
Small overshoot that is frequency dependent
Does not work with opamps that have input protection diodes
Parker
Brewery Updates!
Installed
Tubing
Pumps
Pots
Waiting on
Stainless mesh basket
What is left
Design and build the grain crane
Mount electrical box
Finish wiring
Paint and sealant
Electrical Box
Might have put the power input in the wrong spot!
Need to finish the wiring.. Need to order more wire I think...
R.F.O.
Rules of thumb - Are they obsolete?
Next week we have Al Williams on from Hack a Day
If anyone has any questions for him let us know in slack!
