Yes, it was quite the trip. I just got in on the 29th 10:25am PST at YVR. So I have only really had 2 or so days to recover from jet lag. The flight coming back was cramped (typical Air Canada) but only around 8hrs 45 minutes of actual flying time. Not terrible.
Tensions on the peninsula were pretty low. North and South still seem to be talking to one another, so... However, relations with US are another matter entirely.
Biggest issues in Korea this time was the catastrophic air pollution that for 4.5 days kept us from going anywhere. 160-250 ppm of micro particles ( soot from power plants) Not generated in S.Korea.
Other than that I managed to visit the new Maker City (maker space) at 55-8 Jongro 3(sam)-ga and meet the head maker/curator. I am going to try and bridge our victoria makerspace with maker city somehow. Will get in touch with VIATEC makerspace to see if this is indeed possible.
I was able to meet ex-colleagues from Seoul Metropolitan Government, as well as other associates. More importantly I was able to have time with family. That was the highlight/main purpose of the trip.
Air in this shot is clearing up. When pollution was at it's worst you couldn't see the school next to the highway. (air here is at around 90-100ppm)..note the mist (actually pollution)

No mountains visible from Gwangwhamun (day 3)- Pollution is at 230ppm here. Very hazardous. I am wearing a hepa mask. Sky is completely greyed out.
Maker city at 55-8 Jongno 3(sam)-ga. Maker City Seun (Se woon) is not correct romanization

Students filming a youtube series for the makerspace. ( not a huge amount of physical workspace) but it's spread over 2 rooms.
Note the 3D printers..
Big CO2 laser cutter with under water chiller at the base. (100W) I think.

The makerspace is also complete with its own biolab and bio-hacking lab. TIDE institute. Students here were making plastic from bacterial rafts from Kombucha. - Synth-bio leather. very cool stuff.
Currently the biolab is starting to print biomaterial (living cells using current off the shelf 3D printers that have been modified)
modded 3d printers for 3D bio-printing.

Makerspace tool cabinet!
Day 4, off to Yongsan to see the part vendors at ETLAND. Yongsan has had a few major changes. The old computer shops are pretty much all gone and 2 massive new hotels take up the space. Novotel and ibis STYLES (Seoul Dragon City)...
Across the way is ETLAND parts vendors, a movie theater, makerspace, lego land, Youtube studio ...etc
Great place to get cameras..etc There are several battery stores all stocking LG chemical nad Samsung breaded 18650 cells upto 3500mAh. Sorry, nothing larger than 18650 cells available on store shelves in ROK due to safety regulations.
Bottom of ETLAND mall... every arduino compatible board you could ever want is here. I recommend the Korean nockoffs... they're cheaper and use the same components. 5,500KRW for an ATMega 2560 board! Pretty nice!
