Everyone thought Luigi was a joke until he automated the blue shell
Sorry Luigi, your GPS location is in another castle

Honestly, for this sort of security you just need to raise the bar high enough that someone can’t create an “Easy button hack” to sell on ebay for the real common criminals. For that to happen, the lock needs to be more wide spread and stable than a Sparkfun hack. All of this is pointless anyway if they use the “brick” method (brick meet glass) to get past your amazing lock.
On the other end of the spectum, I doubt there are many elite-cyber-hacking criminals that also want to risk breaking into a common person’s house. I also doubt they will scrutinize a small Sparkfun hack that has very low proliferation.
The whole point of this post is that the risk is low (IMHO, grain of salt included) because there are WAAAY easier targets or better payoff. Just don’t have a flaw that leaves your house unlocked while you’re gone. I will now completely digress and say that attention to security details for the sake of knowledge is a VERY worthy pursuit. Hack away fellow Sparkfunions!

Casey didn’t know why, but he always got the feeling that the US government was looking over his shoulder.

a nazi kicking a kitten…… oh wait, you want functionally terrible. A fire safe, chair leg, motor bearings, 3D printer hot end, pillows, a holster for your Heaterizer XL3000 with fake flames (wait, no, that would be awesome)

Wow, if student groups are screening and doing burn-in, I’m impressed. That’s an amazing learning experience. Placing a transistor in a schematic is one thing. Knowing how it can fail, how it changes over temperature, what your margins are (and on and on), can sometimes be the real engineering. My hats off to them.
Exactly, plus transitioning between those extremes causes mechanical stress. Combine this with the vibration seen in a rocket launch and you have a recipe for finding your solder joint problems REALLY fast.
The level of engineering that goes into any space hardware is amazing.
Being within the Van Allen belt might allow for COTS parts, but I don’t see COTS parts all that often. While radiation might not be a problem, reliability is. Especially in mission critical electronics. Traditionally Mil Spec and screened parts have been used in launch vehicles and satellites (at least the parts I’ve worked with). It’s possible they might use some COTs in the space station just because you have a human around to fix any broken components.
No public wish lists :(
