I had decided the Pi Zero this web sever is running on was not suitable for its original use as a controller/monitor for the 3d printer I had originally attached it to.
I then bought a Pi 3B+ to attach to the printer and an adaptor to convert the pi Zero camera to the Pi 3 B+ board.
The 3d printer is currently partially disassembled waiting for me to complete the build of a heat chamber and printer stand. I will buy a new pi for it when the rest is built.
In the mean time I had avoided setting the pi as a SNES emulator or retro game machine as that seemed common enough and I have played with a lot of Linux and windows based emulators in the past.
That was until a few weeks ago when a friend of mine completed a project we had talked about that had pricked my interest in the pi as a games machine. I played his and I am hooked!
The total immersion of standing at a full size arcade style machine, with proper old style joysticks and sound bombarding you as you peer into the screen as you play a game from your past is just amazing!
My project begins…
The fist step was to flash a version of “retropie” to my pi 3 b+. As I type the Pi 4 in now available with up to 4gb of on board ram. I am not sure how mach improvement upgrading to one of them holds, and the Pi 3 B+ seemed to run fine for the games I was most interested in playing. So for now at least my project will be using that.
I started with a new company and while playing with one of the mains controllers they supply, I used my heater as a test load.
Two problems with that.
First the heater on half load is about 500 watts and the mains controller is only really supposed to be used with loads up to 300 watts.
Second me! I could and should have operated just the fan section of the heater safely in the limits of mains controller. However I forgot and at some point in my testing I switched the heating section on.
This resulted in a heater having enough power to get hot but not enough power to drive the fan properly.
Had I not been full of cold I may have smelt the heater before it tripped the not reset-able thermal fuse.
My wife smelt the issue and asked me if I had been letting the smoke out again! It was too late by the time I investigated the equipment.
Today I have taken the unit apart and confirmed the RY 121 Thermal fuse is open circuit. It is rated 250V 10A 121 degree Centegrade.
I have ordered 5 for 99p off a auction site.
