Emergency DEF bypass

[GUS2000]

Since there is no "patent protection" on this, the only option i see to understand how his device is designed and implemented is to have a neutral third party review his device and compare it to the device that is a solution for a fraction of the price.. Is your friend willing to do that??

does he have a website?? i would like to have one of my auditors review his specifications against the DIY solution.

I've spoken with him, and he's confident in what he builds, the Arduino board, cables, etc. and his labor costs...and it's quite a bit more; like around $250.

He's fully aware of there being a dozen DIY solutions out there and encourages anyone to use them if they so choose...so long as they work ON THEIR OWN coach.

However, as mention before, he's building these primarily for a Newell coach which comes at the obvious increased liability as well as the "almost always" tech support calls at the worst possible timing.

The question is where did he get the software? To my knowledge the only software written for this effort is what I put on GitHub. I put the firmware out there with a non commercial license. So technically no one can sell these. The firmware is available to end users who build their own. Additionally, I only put the binary version of the software out there. The source code was not made available to the public for fear that folks would use it as a starting point for a delete capability which I want no part of.

I’ve been working on improving the device in several ways to include commercial waterproofing (ie potting) and adding additional sensors in order for it to eventually be a legal replacement for a failed head. We’ll see.

I’m currently building these at a cost of $30 plus labor.

I don’t know. I can’t speak for him, but being a software developer, himself, I’m pretty confident that he would respect any conditions of use, if there were any.

Also, to be clear, what he’s making is for the fellow Newell owners, not commercially sold. Seems pretty simple…a Newell owner has a failure, he builds them a box, they pay him for his time and materials, and they’re back up and running as a happy camper…who tells 2 friends…and so on.

As for your cost to build…wow…people should jump on that for $30! (BTW, my buddy’s hourly rate is $750/hr).

I had this in my files for a “some day” project, and it’s a heckuva lot more than $30; more like $180 in parts. I recall my buddy saying you can’t get some of these boards. Not sure why.

As the linked page states, that’s the original build. After we came up with that solution we found better development boards for the job.

No need for the $150 board when you can go with the CANBed board for $15 (even less in quantities of 5, 10 or more). And the CANBed board is a better solution for other reasons such as a bootloader that makes the board look like an external drive where you can just drag the firmware file to the board as opposed to using an IDE to install. Literally takes 15 seconds to program the board.

I’ve build several DSS devices for Newell coaches. Same connector as the Spartan. The devices don’t care if it’s on a Dutch Star or a Newell, but those that have a Newell typically are used to overpaying. I just walked through a 2025 Newell. Nice coach. It was selling for $2.7M!

I built mine a couple months ago for $30 in parts. Your buddy is gouging poorly informed consumers and appears to be an intellectual property thief. I'm not sure why you keep repeating that he's selling them to Newell owners since that has absolutely nothing to do with it.

I know my parts were less than 50, took about 2 beers time to build

Wow, good info…figures that this type of thing gets cheaper. Now, if ONLY the Newell coaches would get cheaper, huh? Geesh!

I’ll pass along your info, but do know my friend said the code he got wasn’t on GitHub, nor did it have any usage stipulations…just an FYI.

There are several websites that provide a download link to the GitHub repository or are hosting the file. The firmware is at the link below.

You should invite your buddy to join here to get his input and understand his development and sales process..
