I’m planning on integrating a Raspberry Pi Zero W (a tiny, relatively easy to program micro-computer) to remotely monitor my GF. For those that aren’t aware the RasPi Zero W has a micro SD card slot, a mini HDMI port, two micro USB ports (one for power, one for USB), and 512MB of RAM. It has a single-core 1 GHz processor chip, and built in wifi & bluetooth. It’s a lot crammed into something barely bigger than the size of a stick of chewing gum.
A stroke of luck and I chanced upon this:
Wouldn’t take much to add the waterproof temperature sensor (low temp)
It would be possible to 3d print a cap for the coolant reservoir with a passthrough to allow a watertight grommet and liquid rated temp sensor. Of course you could also measure internal ambient temp, humidity, and if you were feeling froggy and could reach it, also monitor temps of the PSU, but that would require due caution for circuit isolation. I’ve been thinking of a way to create an inductive load sensing circuit to work with a RasPi program to turn on my exhaust/filter blower and have an automatically timed post shut off cool down/continued venting.
The Raspberry Pi (RasPi) Zero is the tiny version (there are other similar boards that are even smaller), but the RasPi Zero W measures 66.0mm x 30.5mm x 5.0mm / 2.6" x 1.2" x 0.2". So it’s tiny enough to fit inside the GF on the left above the coolant reservoir.
Mine is to arrive in the coming week, and I did order some extension ribbon cables which are slim enough to mount the RasPi on the outside and snake the cable between the lid and or the front door (perhaps up from beneath. I’ll figure out the ideal way to mount it after it’s assembled and working. I did order the 8MP 1080 camera for it as well. I’ll most likely be making a duplicate one to install Octoprint on for my FlashForge Creator Pro 3D printer too.
