fixing blown digisparks

[CBcracker]

I've found out (the hard way) that it doesn't take much to blow the diode on the USB 5V line for the digispark.  For the two that went on me, they didn't completely blow, they would pass some current, but at a low voltage (~2v).  I was able to fix them by bypassing the diode with a jumper made from a common 1/4" staple bent into a U shape and soldered to the two pads at either end of the diode.  See the attached picture for the diode location.  With the diode bypassed, you also get full 5v whereas with the diode there is a ~0.3v drop.
Soldering tip: I found using a toothpick to put some flux paste on the jumper helped temporarily stick it to the diode pads before soldering it on.

Nothing new to me ;-)

i had only a bigger through the hole version available ;-)

If skipping diode, i think it is easier to solder a small wire to the 5v hole on the side of the PCB, and solder that to the nearest corner of the nearest golden strip on the USB connector - that is the one which usually carries the 5v through the diode. Both easier than trying to solder surface mount things

I noticed the photo of your digistump with the attiny removed (you removed it with a knife???), but I hadn't noticed the replaced diode...
I guess neither of us aren't afraid of blowing things up. :-)

I removed it with a scalpel.  One-time scalpels are very neat tools, usually cheap @ ebay or amazon ...
