Are you using a RCT pro board to test the ic's in this video?. If so, could you tell me where you got the components from in the UK since I'm struggling to complete the B.O.M.
I would vote for tantalum one but.. as it’s not exploded before when maybe it got power, I was dubious. I was instead pretty sure it wasn’t related to electrolytic ones.
@@RobSmithDev 🙂 Also, would it be possible to use a multimeter to find the short, by measuing 5V and GND at different places on the board - since the length of the copper traces should give higher resistance if the short is on the other side of the board?
conspiracy theory: in addition to the real "not electrolytic capacitor" short, all capacitors were shorted but since they've been removed now we'll never know! given the ohmmeter reads very small resistance near the connector I reckon it's at the connector
@@iamdkk Meter shows ohms in that mode, but I did try that on the normal ohm setting, even on its highest accuracy it still read as zero. A more accurate meter might help
Try using Tin Foil and Kaptan tape to protect your heat sensitive components/connectors ;-) Also you can pour IPA onto the surface mount caps to see if you can see where it evaporates quickest when applying 5v to the board.
I tried with kaptan tape - I think the stuff I had was fake as it was shrinking under heat hence why I desoldered stuff. Watch the sequel! It’s more fun!
I wonder if hot tweezers would be useful to remove those caps.
They can be, sometimes - I think sometimes they work great. I don’t have any though. I’ve heard some people have issues getting them hot enough
works like a charm if you have good ones

This video doesn’t even get as far as the ICs but if I understand correctly it probably wouldn’t test some of the more custom ones right?

There's new firmware available for it but I have to build it first 😁

Good detective work, I guess hopefully we’ll find the cause in part 2
Also, when using a heatgun near plastic parts, cover them with kapton (spelling?) tape - much easier than desoldering them
Lol, yeah my spelling isnt perfect! - you'll see I use it later on

Sometimes its possible, but given how strong a short it is it literally measures zero all over the board! - dont worry, we'll sort it in part 2
@@RobSmithDev looking forward to part 2 🙂
@@RobSmithDev The spelling part was on me, since I wasn't sure how to spell it :)
Anyway, really like the videos.
I'm paused at 2:32 and my guess is none. I guess it's a bent pin on the PCMCIA connector.
Interesting guess! Certainly the most unique so far

Unfortunately it reads zero ohm everywhere I guess my meter needs more accuracy but you could be right… we’ll hopefully find out in part 2
@@RobSmithDev I think that's because it is in diode test mode in the video

I'm going with No 2
Interesting….. I guess part 2 may have some answers
I'm going to go in the opposite direction and say 3 of them are shorted...
interesting....!
17 and 18. Then again I'm a total n00b at this :)
I guess that’s why it’s roulette! All fun though.
My guess is 17.
Interesting guess. Maybe I should have asked why as well 😃
@@RobSmithDev Completely uneducated random guess just to join in and have fun. :P
😃 glad you’re playing along
