Would someone be willing to do a quick check w a multimeter? I don't want to fry my motherboard when I attempt to power this on.
Gulp. Not good.
I'm not sure that my old Pico does have a cap above the 5v connection. Do some googgling for images of your pico and see what you can find. It is tricky soldering and if you are not directly using the pico (I mean if you are using an extender) then tapping into the purple wire itself is the easiest way to get the connection. Another option is to solder your wire to a small rigid pin and try and shove that down the connection hole on the pico to wedge it in place.
If you think you have bridged a pin by mistake then I strongly advise getting a solder sucker or trying some of that solder wicking stuff that will help you to de-solder the area.
You could also try, if you have just made a slight bridge, using a sharp knife to cut the solder connection that you made by mistake but do check under a magnifying glass and make sure you really have cut the bridge properly before turning on.
I will put a warning about this in the first post.....
Edit: Was it this Pico and capacitor? If so, then unless it is a huge amount of solder then you may have success with a craft knife....if it is a big blob then go for the sucker (!).
Hope it turns out okay for you. Let us know.
Turns out this wasn't as bad as I expected. It was a Pico-Psu 150xt, and I bridged the 5v standby pad with the capacitor directly above it. I spent a long time trying to desolder the bridge using a vacuum and wick with no luck. Even though there was no visible solder the ohmmeter was saying they were bridged.
Then I remembered, it's a 5v standby, meaning it's going to output 5v even if it is not attached to the motherboard. I figured I'd wire it up without the mobo, measure the voltage, and worse case scenario it would give me a bad read and I'd have to buy a new Psu.
To my excitement, it read exactly what it was supposed to - 5v. No damage done. It turns out, on my Psu at least, those two points are bridged internally anyway. Lucky me!
I went on to fully assemble my i3 cube for the first time. Everything works great - including the proximity switch and the LED.
Thanks so much for your helpful post!
