Bit of feedback on a live stream

People suggesting YouTube live
Will set this up for episode 242

The little things no one sees that make projects take forever
3D printer update completed

New fans

TI calls for lower-cost sensors to boost robot adoption

“We don’t see as many robots as we’d like”

Elon Musk’s Neuralink implant

Pig example

High voltage low current measurement - The circuit evolves

Adding resistance measurements
The new process

Use the resistor measurement probes to measure the screen resistors values and record those
Use the resistor measurement probes to measure the cathode resistors and record
Plug test harness into the DUT
Begin test
Program will read voltages and using the resistance measurements it will give you a target voltage.
Turn trim pot to set idle current such that the power dissipation is met

The load is dynamic and this is an unregulated power supply

Looking for bananas

Want to have “multi-meter” banana connector
History of the banana connector
Technically a binding post
