@@ -561,3 +561,47 @@ because the kitten hisses when reset.
 To my disappointment I only ordered 100 LEDs, which is _barely_ enough.
 And to an electronic engineer _barely_ enough is not enough. We have to
 keep a redundancy, so I ordered 200 more.

+Just finished the first session and I am so fucking exhausted. Three
+hours, working nonstop. I forgot where I left my bag so I couldn't even
+show the slides I made.
+
+Long story short, we instructed 8 terrified beginners how to do reflow.
+Out of all participants, one managed perfect paste on the first try; most
+made it in three.
+
+Here's some of the jobs that made me go "hmm that's not bad":

+
+We began toastin' at exactly the two hour mark.

+
+I then spent like half an hour manually fixing shorts, reinforcing the
+battery holder, etc. Everyone's electronic kitten purrs and hisses, but
+not every LED turns on. It could be a fault in the touch sensing area,
+MCU, resistor pack, or the LED itself. I did not have the time to diagonse
+one by one. On one board this happened on the tail, which makes the kitten
+immune to tail pats, and consequently really tame and hardly hisses.
+
+Everyone got their product at 21:something and I cleaned up the place and
+wiped every tool until minutes to 22. It's a miracle we finished the whole
+thing before 22:00, especially when the staff is made up of three
+ex-terrified beginners, two of whom literally learned reflow 48 hours ago.
