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!

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. 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.

Previously, I wrote about Upgrading a Solar Power System and mentioned a cache of new Lithium Iron Phosphate (LiFePo4) cells. 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.

I have been interested in gardening since I was a child and spent time with my great grandparents who were gardeners. The Square Foot Gardening method was developed in 1976 as a simple alternative to labor intensive and inefficient row gardening. Explore the possibilities . . .

The shop here at the ranch was built in 2000. I got lots of work done there, but by 2011, two things were clear: the wooden exterior doors were in dire need of replacement and it would be nice to have a covered outdoor space to keep sawdust out of the shop. I installed new pre-hung metal doors and with the help of a neighbor, added a 20-foot extension that year — complete with a metal roof. There just wasn’t a concrete slab.

I’ve been threatening to build a storage shed at the ranch for some time now. After going through everything in the shop and selling, discarding, or giving everything away I could, it was still too crowded to work effectively. I needed more space. A friend had recently mentioned a sale on small buildings at Costco — it was worth a look.

With the Solar Generator Project underway, it is time to mount the solar panel array. Last May, I purchased eight Renogy 270-watt solar panels similar to those in the Solar Rainwater Project. At 65 by 39-inches, and weighing 65 lbs., they require a substantial mounting system. In the Solar Rainwater System, I had the advantage of an existing building with a south-facing roof that could hold four panels.
