Hi there, I have small problem - already asked on fb (i ve send msg to Hackspace Manchester), and admin recomend me to signup here and ask here so…
I have got PCB board, but I dont have any schematic, one of the sensors doesn’t work properly so I check pictures of the same PCB boards on websites, and I found that in the neighborhood of sensor power tape plug there are missing two smd capacitor (as I suppose smd capacitor)…
I compared pictures when I started looking on pcb, with current state, and found that I miss one capacitor somewhere in home - so I spent about an hour with headlamp and found it deep in carpet.
After I found it, I immediately asked my frind which is in electronic - so he told me what it could be, and why he is not able identity voulme and type of this small piece of electronics.
Thats how I know that it could be smd capacitor, but as he mention I would need to find and ask electronics to use some tool to Test SMD Inductors…
I wonder if there is some tool to do that in Hackspace? I know about Hackspace from Fablab, but Fablab doenst exsist anymore, and I have never been in Hackspace yet. Maybe some of you would be able to check/test so tiny inductor, and would let me know what I should try to find?
thats picture of PCB which I have, I marked on red powertape to sensor which is on other side of pcb, and in white circle one of SMD Inductors, and place where should be also other one.
This one which is visible in white circle I lost, but found it in carpet,… and there is second picture which shows missing element
picture is made with iphone with zoomlens (x24 + iphone zoom)
and that is real size
Maybe some of you would be able to help me,
pls let me know
thanks in advance
ps. i am sorry if I post in wrong section of forum!
