It's always a good idea to regularly refresh the electrical engineering knowledge acquired during your studies, it forms an important foundation for understanding ICS/OT systems.

Because one thing is clear, stagnation is the first enemy you can actively combat.

⚡ When Static Electricity Meets Smart Logistics… Reliability Matters.
In today’s high-speed logistics environment, intelligent pick-up light bars are transforming how packages are located and retrieved. But behind every smooth pickup experience lies a hidden threat—Electrostatic Discharge (ESD).

Don’t let your protection circuit become a decorative component.

If your TVS isn’t placed right, specified right, and backed by proper system design, it’s not protection — it’s illusion.

Read the full deep dive and discover why real engineers design protection first, not last.

Here we go again... Obtained a thing. Thing was cheap. Thing was advertised "sold as is, no return/refund". Thing needs love.

Thing is an ETS Lindgren 7405 near field probe set, including the optional amplifier. Usual price is USD 2-3k.

The integrated batteries from 1992 (original ones, manual is (C) 1991) are NiCad and a special size (LR1/N 2/3rd AAA) and unhappy. They are able to power the amplifier for some time, but one is dead at 0V and shows signs of corrosion on the plus pole.

The amplifier is basically a NE5205AN wide band amplifier with input protection, a power switch, a power LED and a crude resistor-current-limiter charging circuit (power supply is 12V 500mA) for 4 NiCad cells in series.

I ordered fitting NiMH cells and a fitting (USB) charger to upgrade this to Cadmium-free.

It will be interesting to compare this to cheap " PCB with SMA connector" probes.

Combating KT148A voice chip burnout in charging pile apps? Pins 7 & 8 (SPK outputs) can fry from surge/EMI. Design tip: Add an LC filter (33uH inductor + 102 cap) on the output and use twisted-pair wiring for the speaker. This simple combo filters noise and reduces common-mode interference, ensuring long-term chip stability in tough environments. #KT148A #HardwareDesign #EmbeddedSystems #EMC #SurgeProtection #EVCharging #ElectronicsEngineering #Reliability
