MEP EP#249: How Soft Are Your Diodes?Parker
Signed up for the EXTRA LIFE charity this year to raise money for the Texas Children's Hospital
This Saturday (Nov 7th) Parker will be broadcasting a 24 hour video game stream
Will be playing the Half-Life 2 video game all the way through
This includes the two episode expansions to the base campaign
Difficulty level will be set to 'Hard' and I will be attempting to unlock all the achievements at the same time.
Donations are tax-deductible and 100% of it goes to the hospital
Learning some javascript to build plugins for the stream
PinoTaur REV3 has gone gold
Added more current sensing
Low Current Allegro ACS70331EESATR-005B3
High Current Allegro ACS711KEXLT-15AB-T
Changed Relay to a socketed relay type
ISO micro relays type
On PCB flyback diodes for coils
MRA4004
Relay is driven by both the MCU and the Fault pin on the high current sensing IC
Walmart fires store robots
Saw improvements in inventory control with the robots, but not enough of an improvement in revenues and other measures.
One premise is that stores will sell more goods if the shelves are stocked and wanted items are made available

How soft are your diodes?
Softness factor - a definition of the reverse current characteristic
Ta = time when charge from depletion region is removed
Tb = time when charge from semiconductor region is removed
S-factor = tb/ta
S-factor = unity = soft recovery
S-factor unity = fast or snappy-recovery
General purpose/fast recovery (FRED diodes)
The SSPS?
@zane is going back and listening to episode 1
What was the SSPS?
What were the specifications????
Where did we leave off
