When I was looking at designing the Level Up module I wanted to get a sense of any pain points and the reasons that would trigger purchasers to return their products. It didn’t take long before I noticed a common thread. The commenters were clearly frustrated with two aspects, but we are going to focus […]
When we bought our EPro 19FD, I was informed that I should buy a good surge suppressor and power monitoring device to protect our new trailer and all its valuable electronics. My first thought this is overkill… right? After all we had camped with a tent trailer for 20 plus years and never had an […]
Introduction Back in the summer of 2023 we experienced a rather strange electrical problem with our trailer. We had a situation where there was no DC power in the trailer. No lights, fans, radio, tv, etc. It was the strangest thing. All the circuits worked fine when: The battery charging, power jack and the brakes […]
Introduction So what do you do with a spare Nanuk 905 IP-67 case? You design and print a 3D insert for said case to store… wait for it … batteries. I can hear you all now… that’s completely ridiculous! Well of course it is, but thats not really the point. The point is, because I […]
Introduction After looking around for a semi-professional 3D printer for six months, and then agonizing over the price for another six months I finally purchased a Ultimaker S5 Pro bundle in January 2022. Why I Bought It I bought my first 3D printer for rapid prototyping in 2020-2021. I started off with a JGAurora A5 […]
One of the things that I really disliked about our 19FD was the low ground clearance. The sewer cleanout and the stabilizer jacks have been a constant source of worry for me. We have also had issues trying to fill our sewer tote on some sites as the sewer cleanout was below the top of […]
Introduction We purchased our EPro 19FD in August of 2019. The unit is a 2020 model year. I should point out that we still love this trailer, as you could be forgiven for thinking this trailer has had its share of issues, which I would argue that it has. If you have never owned a […]
So back in the mid-1980’s, I came across the SP0256 Narrator Speech Processor from Radio Shack. The chip was manufactured by General Instruments or more specifically General Instruments Microelectronics. The company had a number of 8-bit and 16-bit microcontrollers, along with some ROM, EAROM (electrically alterable ROM), and telecommunications chips that were spun into a division called Microchip. […]
Introduction As with most of my projects this one has been on the drawing board for a while. Well over two years in fact. This project is looking to scratch a very specific itch, specifically to augment Wi-Fi measurements with noise measurements. If along the way we happen to add additional features that extend the […]
Mobile Power Meter Application So in this article, we’re going to switch from the power meter itself to the mobile application that serves as the remote display. The power meter application is a cross-platform application for Android, IOS, MacOS, and Windows. The application starts up by searching for any and all power meters that are […]
