LilyGO T-Beam SUPREME Case Comparison: Cost, Durability, and Field Practicality
After surveying available case designs and materials, printing several variants, and comparing service-bureau options, I concluded that the Alley Cat case offers the best balance of durability, access, and discretion for real field use. While I specified nylon for my print, other materials such as ASA (Acrylonitrile Styrene Acrylate) are also viable; the rest of…

HollyWood
These were the last two of about 9 trunks of holly that were 20-25 tall at Peck Cottage next door. These two were especially difficult because they were leaning towards our house and the iron fence and Internet lifeline were in its path were it to fall into our house. I used ground anchors with…

Sawmilling Redwood Boards
When we lived in Napa, CA, we removed a coast redwood (Sequoia sempervirens) that was 6 feet in diameter at its base and 12 feet from the corner of a Victorian cottage we ran as a vacation rental and threatened the foundation. Moreover, I learned from a former lumberman that redwoods have “sleepers” which are…

Greenhouse Bench Prototype
I’ve created a prototype of a greenhouse bench based on my memory of benches used in greenhouses made by Fricker’s Greenhouses of San Gabriel and Southern California Greenhouse Manufacturers of El Monte. Both of this institutions have vanished and there is almost nothing available on the Internet about them. This was a project scheduled for…

I sent and email and left a voice mail with the Florida vendor Saturday afternoon when I discovered the rot, but they had closed for the weekend. As…

Visual Diff Of Printed Circuit Boards
A light meter project that measures sunlight in a similar way that a rain gauge measure rainfall caught my interest. I’ve been trying to measure how much sunlight my orchids receive in the greenhouse during low sun months in Salem, OR. The project is a paper published in Electronics titled “Open-Source Photosynthetically Active Radiation Sensor…

Blc. Honolulu Sunset ‘Wakida’ AM/AOS My first “division” from the mother plant winning the American Orchid Society Award of Merit. This plant it is not a mericlone. A mericlone is a plant propagated from a tissue culture taken from a desirable plant. A single mericlone can produce limitless clones. Mericlones often are slightly different because…

Greenhouse Sensors: Version 1
Below are the three sensors I assembled for tracking environmental data. I have two in the greenhouse and then one outside. Currently, the three sensors provide temperature, humidity, and power readings every second and send their data by radio to the base station where the data is then saved into a database. From the database,…

Greenhouse: Vandachostylis ‘Ploenpit White’
I built my 12′ x 22′ Arcadia Glasshouse greenhouse in the Spring of 2019. As I was finalizing the build, the opportunity to acquire and plant the next door property, Peck Cottage, arose, so I devote my full attention and resources to the new acquisition. The greenhouse was left on life-support, if that, only keeping…
