Which expeditions yield tech advances?

[Summanus]

I'm struggling with power on my latest game because I haven't been able to unlock any solar panel advanced tech. Can anyone give me a clue please as to which type of expeditions give you a chance of finding this kind of thing?

I usually see breakthroughs from the "Self Destruct Signals" but they are rare and don't always offer options I would consider useful.

You're not going to believe this, but just 10 mins after I read your comment I got an alert for a "Self Destruct Signal" expedition, so I went to it straight away and it gave me the choice between Graphene Solar Panels or advanced batteries

You were spot on, thanks

Nice! I've never had that one myself. Also been wondering how to get other techs.

So the Self Destruct Signal is the only expedition type that offers it?

Not sure if its the only one that will give you tech blueprints, but its certainly a very reliable one. But as ExavierMacbeth says, they are fairly rare expeditions - so grab them quick when you see them.

I used to think the armoury expeditions gave blueprints too, for weapons and armour upgrades, but now I'm not so sure. I definitely got Carbon armour and pistol & sniper 2.0 from somewhere though.

In a way it makes sense. A breakthrough tech is a very nice prize. If you could get it from any other expeditions you could take your doodly time to get it. Nice prize but less exciting in the build up.
One of the reasons to have at least 2 balloons so you have one at the ready at all times should these expeditions pop up.

I think thats the only one that can give you the Breakthrough techs. I have seen 2 variants of it... One that offers Solar, Wind, & Battery... the other that gives you the choice of a 2.0 weapon or carbon armor.

I have gotten actual 2.0 weapons & Carbon Armor pieces from both Armory & Shooting star events... but only get the Breakthrough blueprints from the self destruct signal.

EDIT: My comment before about not always finding something useful is when I get the weapon one... The 2.0 weapons are expensive to make... at least in the Stranded Scenario which is the only one I have played, probably better to have in other Scenarios.
