About a year ago, Marilyn and I made the leap and purchased a Hyundai Ioniq5. Our motivations were rooted in reducing fossil fuel reliance, harnessing solar energy for transportation, cutting fuel costs, and simplifying vehicle maintenance.

I’ve made about 20 posts regarding my adventures in Solar Energy. They all lead to a Solar-powered “Gas Station” for an Electric Vehicle (EV). As prices for solar equipment have come down, the idea is within reach on my budget.

After building a wooden enclosure for the Lithium Ion Solar Battery, it was time to think about copper bus bars to connect all those cells together. This requires a little math, since the bus bars have to be big enough to handle current demand, but not too big — copper is expensive!

With 8 kilowatts of Solar panel to meet our power needs, it was time to think about winter heat. The solar power could be used to pump water, provide lighting, charge various devices and run small appliances, it just wasn’t going to be enough for heating — especially at night. We have a nearly endless source of deadfall live oak here at the ranch though, and a wood stove was the obvious answer.

The first step in building a really big lithium ion solar battery is the enclosure. At a minimum, it will hold 64 of the LiFePo4 cells and support their weight; about 325 lbs. It also occurred to me having some mobility would be nice.

It’s been a tough couple of years. The last two years have seen below-normal rainfall. While not unusual in the Hill Country, they have been remarkable for the depth and severity of the Texas drought. During the years ending September 2022 and 2023 we measured just 11.75 and 10.65 inches respectively. That compares with an average rainfall of between 30 and 35 inches.

The next upgrade for our Solar Power System was a Really Big Lithium Ion Battery (RBB). When we first installed the system in 2020, I didn’t have a cost-effective solution for Lithium Ion (LiFePo4 chemistry). That came later with the acquisition of a lot of LiFePo4 cells. Since then, I’ve built two small batteries to get used to the technology; one as a portable solar generator, and a slightly larger one to power the ham shack. With those under my belt, it’s time to tackle a 48-volt battery to replace the existing lead acid batteries.

One of the dreams here at Roy Creek Ranch has been to add Solar powered heating and cooling (HVAC). We’re now producing substantial power from our solar array, and it would be nice to use that power as much as possible. Also, for those times when the grid fails, some heating and cooling will keep us more comfortable and maybe even a little safer in extreme weather.

Just before disassembling the Thomas Transistor organ to create a VPO, I tried turning it on for one last listen. I wanted to sample a few of the basic sounds for later use building a sample set or synthesizer patches. It hadn’t been used for quite some time, though I had no reason to suspect it wouldn’t work. Within a second or two of powering the organ, there was a loud pop, followed by a very loud hum. Time to get it on the bench!

we talked about converting a Thomas Transistor Organ into a great Virtual Pipe Organ (VPO). This early 1960’s era electronic organ has good bones, but not worth restoring to its original condition. We can salvage some key components however. In this post, we begin with disassembly. Besides removing the parts we’re not going to use, it will also make the cabinet lighter. This is important since the organ must move to the second floor our home to make way for a remodel. with disassembly.
