@kickflipindy@Doyle477493545 Haven't done it a lot but if you have some solder paste at hand (high quality) + a heat gun that might do the trick. Once it is liquid it will find its way.
You might not have a mechanically stable connection but using some spray coating afterw. will give at least some stability.
NE555, NE556, LM324, TL082, TL084, uA741, uA747, LM358: all such staples of electronic engineering. How many different ways have vendors implemented these designs across revisions? Well let's find out!
Shoutout to my local component shop for stocking this nice variety of fossils.
@isciurus Could you elaborate on why it is only partially inspectable? I assume it is due to the obfuscation but it would be interesting to known what aspects in particular are troublesome.
@hatr Just wild guessing here, but it could be related to a particular timing between states of the handshake, specific IP addresses that are used during establishment of the tunnel. Possible that proton implementation has some specific patterns when establishing connection.
