RE: LiDAR Technology in Autonomous Driving: A Practical Guide to Key Components

robogary — Wed, 04 Feb 2026 13:58:47 GMT

I always wondered if every vehicle in traffic had lidar would they crosswalk and create errors, or is it like FHSS, the chance of detecting pulses from a different source are unlikely to align time wise, or maybe the lidar pulse is an encoded burst ?

Yes LIDAR has come a long way since I was first involved with it many decades ago.

Nice post. Btw I'm also thinking to make an inverter as a project

RE: What Is a DC/DC Converter in Electric Vehicles (EVs)?

What is the throttle pedal ultimately controlling ... output torque current ? Auto braking/regenI guess would be folded in there as well, with any other wheel slip/traction control detection. Is there is one line available of the regulators ultimately controlling the PWM gating and direction ?

RE: How to Design Robust EPS Circuits for the Future of Autonomous Driving

What I do not like about this approach is that if you lose power in the vehicle, you are in an uncontrollable mass object destined to hit something.

I prefer some type of manual backup so that you at least have some chance of avoiding something bad.

Chip varistors are new for me - will have to investigate.

nice! - I even have an evaluation kit for gridEye that I have bought second-hand but I didn't have time to use to this date... It seems that there is much material here on E14 to learn about it...

Nice. Do you have a product link??

RE: What is a cooling system pump? Circulating water to prevent equipment overheating

robogary — Mon, 24 Feb 2025 17:33:43 GMT

Dear author - This article leaves me really confused.

The subject title refers to an EV cooling system example, however the topic drifts in and out of typical 3 phase inverter harmonic suppression and RFI discussion.

The cooling system diagram infers the batteries, inverter , and motor are all liquid cooled. I knew batteries require temperature control, both heating and cooling , those I understood are forced air convection.

Inverter and motors I thought were also air cooled, but I can see an advantage of liquid cooling to allow motors and inverters to use less heatsink and try to keep at constant temperature in both hot and cold environments. It also adds back in the maintenance disadvantage that compare to ICE engines.

At the article conclusion, the capacitor products listed have nothing to do with an EV cooling system, unless the imagination is stretched to include harmonic heating/suppression components.

These comments are provided to be constructive feedback. Best Regards

That drop off with bias voltage is an absolute killer with ceramic SM caps. I'm using polymer caps more and more in power supply and pulse circuits.

Very interesting information.

Given the planned use of solar, it makes sense to make specific components engineered explicitly for that application.

RE: Ready for your ideas – and available on short lead times: Panasonic Industry’s range of BLE modules

embeddedguy — Tue, 17 Jan 2023 06:54:35 GMT

After I did the roadtest of PAN9520, here on element14, I spent quite some time to search for development kit on Panasonic website. Indeed some Bluetooth devices were that but most of them are based on nRF series. For me it would be interesting to see ESP32 based module so that it has both WiFi + Bluetooth.

The PAN9520 only has WiFi capability as it is based on ESP32s2 series of device which target industrial wireless communication.

The Board is really interesting piece of hardware as it exposes many I/Os to the user and various interfaces.

That's great to hear lead times are coming down.

It is amazing how "short time" is such a relative term.
