If anyone other than me is subbed to the RSS feed, I’m tweaking a lot of things still as I learn Hugo and that is causing all the previous posts to get re-posted. Sorry about that.
I moved all of this to Hugo and self hosting yesterday from https://prose.sh. I love the idea of what https://pico.sh is doing. All driven through ssh/rsync, simple hosting of blogs and static pages, there is a lot to like about it. It does tick a lot of boxes for my inner geek. However….. There were two papercuts with prose.sh that grinded my gears. No subdirectories, so all files (posts & images) ended up in one directory.
Many moons ago I fitted a set of Dallas DS18B20 temperature sensors in the engine bay as I didn’t trust the radiator. I put one in the water hose from the engine to the radiator, another in the hose from the radiator back to the engine. For air temps I put one in the air flow either side of the raditor. To measure this all, I buried a Raspberry Pi behind the dash and came up with a funky set of three relays so the Pi could shut itself down safely when I killed the power.
My car now takes about 48 litres of fuel. I noticed though that the gauge was not going down. Given it is not a car that sips petrol I found this hard to believe. Fuel level sensing is done by the fuel tank sender. It has a float on an arm that moves up and down with the fuel level and that in turn moves a variable resistor. First Hypothesis - Gauge is wrong I fitted a spiyda Gauge Wizard when I fitted the tank as the sender and the gauge were definitely not a matched pair.
I had a thought in the shower this morning that I do my best thinking there. I then thought about why I think best there and came to the conclusion that it was because I didn’t have my phone to distract me. It’s too easy to grab my phone and fiddle with it to occupy my mind. I don’t switch off and just let my mind wander. So to this end, I’m going to purge my phone of all consumption apps i.
I run HomeAssistant on some no-name fanless PC which has WiFi and Ethernet. I mainly access it over Ethernet, but it uses the Wifi to connect to my IOT SSID and expose its MQTT broker to the various Tasmota and ESP32 devices I have kicking around. The problem was that every now any then the Wifi would quietly crap out and all my devices would stop updating. I could do one of two things.
I’ve now made all my brackets, detoured via tidying up the wiring and I’m now on getting it in. This car was designed to take a 6 gallon MG Midget tank. I’m trying to get a 10 gallon tank in. It is not going well. The tank is catching on the diff cover of the axle. I may be able to get away with taking the rear cover off, or I may have to drop the axle from the car.
(Update 04/02/24 Combing everything into one post as it wsa getting tedious) Fitting the new fuel tank to the Fury is the gift that keeps on giving. The original tank had both mounting holes and a pipe on the top to connect the fuel hose to. The new larger tank has no mounting holes. I made some brackets to the profile of the new tank and drilled mounting holes using the top pipe centre as a reference point.
Some notes as I go along. We have A Renault Zoe A Growatt hybrid solar/battery system An OpenEVSE charger HomeAssistant instance An MQTT broker The challenge is to get all of those talking together so that when the growatt battery is full and the sun is shining, any excess solar goes into the car rather than the grid. It’s a little confusing as OpenEVSE seems to push OpenEnergyMonitor as the way to do all of this.
