designed and ordered from them and as always i got it with the option of having all the smd components already populated since they charge no fixed fees for that and then i sorted in my own through-hole parts and modules that i can move between projects but jlc pcb are now also rolling out a NUMBER_TOKENd printing service where you can get parts printed in one of two super reasonably priced engineering resins centered out of pa NUMBER_TOKEN or in full color nylon so whether you're looking to add a precision printed case to your products or just need some functional parts centered check out jlc pcb service at the link in the description below so for today's test i'm not going to use my daily pixel NUMBER_TOKEN because i don't want that to be tied to a printer for hours at a time instead i'm going to be using this xiaomi poco fNUMBER_TOKEN pro that i had previously it's too big for my hands and you know but it's still got an eight core processor clocking up to almost three gigahertz this was NUMBER_TOKEN gigs of ram so it's easily faster than any raspberry pi unfortunately it was the second xiaomi phone that just randomly died on me this one simply doesn't charge anymore but it's otherwise technically fine thankfully we can pretty easily work around the broken charge feature on the poco fNUMBER_TOKEN pro so let's do that real quick the back is already off so all i have to do is to take off the plastic shroud and unsnap the connectors like little legos and then soldering a little lithium ion charger pcb directly to the battery terminals on the back if you're going to attempt something like this please make sure you know what you're doing or ask someone who does because shorting out or damaging a lithium cell like this can go catastrophically wrong pretty easily so here we go a perfectly usable xiaomi poco fNUMBER_TOKEN i mean i guess you could use it like that it's already abominably unwieldy as is as a second phone for reference as to how old and how weak of a phone you can still use i'm also going to throw in this google samsung galaxy nexus look at how tiny this thing is this thing is from NUMBER_TOKEN it has a NUMBER_TOKEN gigahertz dual core processor and NUMBER_TOKEN gigabyte of ram performance wise it should be roughly comparable with a raspberry pi NUMBER_TOKEN which already isn't exactly recommended hardware for running octoprint especially once you start running plugins and as a middle ground i'm also going to chuck in an lg gNUMBER_TOKEN which was already a very affordable phone when brand new but you can now get them used for next to nothing two point something giga has quad core four gigs of ram this should be about comparable or actually a bit faster than a raspberry pi NUMBER_TOKEN. so next up the question is of course how do you actually connect to your printer because these phones you know they don't exactly have a usb port that you can plug stuff into except that they do so android phones generally support what's called usb otg usb on the go so with a simple adapter like this one you can turn the usb port on the phone into a full-sized
