From: "andymeyer" Bob, It's an O-235 C1C with 8.5:1 pistons and dual Lightspeed Plasma III's. Carbureted... No vacuum system or mags. She's flying right now (with 1 mag, 1 Plasma III), but our ramp shuts down for 10 weeks so I'll be doing this upgrade then. My diagram is somewhat derived from the Z11 (might be an older version since it still had the AEC9001-1 in it - I bought your book years ago... Engine monitor is an ~30 channel system with 2 ARM Cortex-M7's (one in the instrument, one back by the engine) and a 3.5inch touchscreen... Should have put dual independent power inputs on it. Maybe on my next rev of the PCBA.

From: "andymeyer" So, this came up in another thread and I was asked to share... Plan is to write it up for Sport Aviation, but this group has been such a help over the years, and such a knowledge-base for both my fun and my engineering career, I'll share here. As is the expectation of this group, I want to learn how to do this better as well. I have thick skin and am open to making this better. My wife laughs every time I cringe and delete all of the traces on the PCBA design software and start re-laying out the boards. It's part of the sickness. This is experimental. I needed a good, data recording engine monitor for my Long EZ. I wanted a better leaning algorithm that I could find on the market, a basic air data computer, more I/O, and a simple interface. The first picture shows the new screen - 3.5" capacitive touch screen in operation, the 2.8" screen for comparison (half the resolution of the 3.5") and the first revision of the PCBA's. The next revision is on its way. The system consists of a module that sits near the engine on my Long EZ which runs a Teensy 3.6 microcontroller that is attached to a board I designed that collects data from 20 channels filters it and sends it via RS232 to the display module. The display module collects another 10 channels of data (and has spare serial inputs for expansion) and processes it on a Teensy 4.1. It stores it every .5 second on a uSD card and displays it. I'm currently flying with the 2.8" version and really like the clear presentation of data, though the 3.5" version affords me more data on the screen at a time and easier viewing. The 3.5" version will be installed with the panel upgrade that I'm getting help with in another thread. Future updates to the software will include some AI for predictive performance and engine health monitoring... The PCBA designs are done (and redone, and redone) in upverter - a great free circuit design tool.The enclosures are designed in onshape and the software is all C, written in the Arduino IDE. If anyone is interested in helping this project along, I'm game... Charlie, passing the joint. My wife and I got a kick out of the video (after the kids were in bed.)
