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.

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.

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.

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!
Continue reading →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. 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 wood stove.

The “ThunderSky Winston” cells had come from a Segway repair operation and were new. A little looking around the ‘net revealed they were still available from GWL Group. With a capacity of 60 Amp Hours (AH) and nominal voltage of 3.3 volts, they looked useful for building a 12-volt Solar Generator.

While I don’t remember much about the food, I certainly remember the restaurant because it had a Pipe Organ. The organ was behind glass windows on one side of the dining room, and a famous organist of the era, Dick Hull, played it while everyone enjoyed their meal. That was the beginning of my Virtual Pipe Organ project.

In particular, a recent upgrade to the battery and inverter system significantly improved our resilience during … Continue reading →
Upgrading a Solar Power System It was time to upgrade the solar power system installed for the shop almost two years ago. I’ve been happy with original system, but it needed expansion as soon as funding permitted. I also wanted … Continue reading →
With summer on the way, and an end to our rainy season approaching, I am reminded of the dry summer last year and concerns about the water table here at the ranch. Fortunately, our water well performed during the last year’s drought, but a number of our neighbors had trouble with their wells. Some troubles were resolved by a visit from the well-service company and a replacement part of two, but at least one well’s water level was low — resulting in low or no water output.
