Hi there, I've been using NodeRed for almost everything now. Since I have a server running, I send almost everything to it and deploy. Fast curve of development. Mainly with sensors and IoT. However, I'm facing a peculiar condition. I'm developing a control system for a 4-stroke engine. The 4-strok…

I have a lot of common voltage loop in the engine. In the past, I tried to power a raspberry from it and it froze from time to time, that is why I need to use this old notebook. Indeed I can add more hardware, but I'm not sure if it will speed or slow down development. In fact, my servos are bounci…

Hard to say more without knowing more about what you need to control in the engine. To fix the local Pi power issues, you would want a battery or super-cap and charging circuit - or a good power circuit - to completely divorce the power loop from the Pi. If you need better control than a remote No…

Indeed vehicle power supplies are often very “noisy”. Best thing would be to get a proper power supply designed for auto use eg with a 9 to 34v input. You can try homebuilt but for the 40 quid or so it’ll stop frying your pi or whatever. I've used these before with good results - mini-itx.com - stor…

I'm modding a single cylinder 3kW generator to use butane as fuel. I'm using STM32F103 to do real time stuffs, however I just want a visual feedback of the system. A dashboard with gauges, sliders and so on. That is why I was considering NodeRed.

Well this guy did something neat in 2016 Hovercraft Instrumentation – Itinerant Ham

Why not use a local Raspberry Pi with Node-RED on it? Low cost, low(ish) power. Run it with Rasbian with no desktop, install node.js and npm install node-red. Or even don't bother with Node-RED locally if you are happy with Python. But perhaps send via MQTT?
