Genesis 3.1 Early Impressions

[Jon Nellis]

@Jon Nellis how long can I reasonably leave the cap plugged in before it affects the battery? I ask because if I’m heading somewhere offshore and will be on a boat for multiple days, my inclination is to leave the cap on the entire time as to not expose the pins to salt from spray.

I recommend removing the nose plug when you are not diving. The motor controller pulls a few watts of quiescent power when enabled, so leaving it enabled for 12+ hours over night can drain a noticeable amount charge. Salt spray will not affect the gold plated contacts, just don't stand it on the tail, so that water can collect in the nose recess, which will enable the controller and cause electrolysis on the pins. Salt spray will damage the charger, so keep the charger out of the weather.

A USB A port on a device? USB A is only meant to be on hosts.

No, USB A is typically used on hosts. There's no law that says it cannot be used on devices. Waterproof USB A bulkheads are much more available and USB A to USB A cables are also readily available at local stores for a few bucks, so we do not have to force customers to buy an overpriced UART or I2C converter to connect to their DPV.

could be great to have a port on the scooter to use for heat system

The rules are set by the USB-IF not by law. It isn't like you are trying to get certified, but it is highly unusual, literally the first time I've seen it on a real product.

Since Fry's Electronics sold I don't think I've ever seen an A to A cable in a store.

We can add a power output to the nose, and it's good for large video lights attached to the DPV, but I don't recommend it for heating systems. More things to get twisted/tangled, accidental disconnect can destroy connector, electrical cable running past the prop inlet. A battery pack on the waist belt is too simple to change. Just because you can take power off a DPV battery, doesn't mean it's a good idea.

Any chance you'll go to a USB-C since they are commonly available as both a bulkhead and cord, plus are becoming the standard on most devices?

Wally world stocks them, Best Buy too, not uncommon anymore.

Amphenol isn't making USB C waterproof, panel mount, pcb pin bulkheads yet.

Wallyworld definitely isn't, at least not in my local area.

Best Buy stocks those A to A file transfer cables. I wonder if the software that they use to emulate the peripheral profile would get out of the way.

Standard data cable, less than $10 in store, $3~5 online. Don't use a null modem cable.

Can you provide a link to one actually sold in store? I can't find a standard USB A to A cable in any major store in my area.

They've never been a standard cable. You made the claim that it was available widely locally and I searched both stores you gave example of and only Best Buy had a specialized file transfer cables which might not work as they have a chip that allows it to deal with the host to host connection that isn't supported as part of the standard USB profile.

Are you looking for a cable to connect to your Genesis?
