We all woke pretty late. Its fun havign the video stream of our house hat I made fro gabe.. we are seeign it with soem mornign glory tnedrels that are lit by the camers IR lights.. cool spooky effect 

Once we were all sufficiently awake we all piled into gabes car ‘jellybean’ and drove about 1.5 hours to part of bavaria called the ‘Franken Swiss’.. its part of the samw Frankopnian regian of bavaria that Gabe lives in.. but its called ‘Swiss’// cuz.. I dunno why. maybe because it looks Swiss-ish ? 

we did a really nice long hike thr9ugh the hilly country side.. it was soooo nice !

About 5 we headed back to Würzburg..   and headed to Aiky.. our favorite Japonese place. just about a miles waok form Gabes.. uts amazing to find such great japanese food in the middle ofgermany .. we go there whenever we can !

after dinner we wnt home.. ontly to find a HUGE murder hornet in gabes apartment . It seriosly was nearly 3 inches long !!!

We tried to get the thing to fly out.. but we couldnt.. and they are super paniful stings. so we had to get him with a vaccum cleaner.. whcih still maies me sad.. all he was doign was hornet–ing..

but it was him or us…  *sigh*

ok.. more tomorrow !

Our plane was late leaving IAD so late arrivign in Frankfurt.. It was mid afternoon by the time we landed// about 5 by the time we got off the train in Würzburg.   

Gbe came and picked us up.. we were so excited to see him and Nova.. we went out for a hike..t he weather was cool.. which was very welcome for all of us. Germany has had soem of the highest temperatures its ever seen.. it even hit h100F here a few times..

we enjoyed walkign and eating plums and grapes that were growign all around in the feilds.. 

we got to lay ball with Nova too.. shes happy to see us.. I can tell. v
Its fun to visit the grand dogs.. we had so much fun with Violet in santa fe !

I know it looks liek fall colors.. but here the leaves are brown from the heat !

we headed back to Gabes.. and headed out to walk around Würzburg and stop  for a great dinner at a real Franconian plance.. It was a grweat way to ‘land’ 

then back home for much needed sleep..

WOrked at home today.. then afternoon, dinae and I headed to the airport *again* .. this time were off to Germany .. We’re goign to see Gabe and Nova, and celibrate our 40th anniversary.  We want to get this trip in before Beck and Max have the baby.. we want to be available for whatever they need

I love travel.. .. and I have to admit, i’m missing home as well 

Saw this poster in IAD.. I swear its the same place we hiked in spain.. its an abandoned rail lline. rail station and prison built durign the spanish civial war and never finished. .. here’s where we visited.. .. its gotta be the same place ! Look for the pictures of the tunnels somewhere  in here 

we wernt sitting together for the flight over.. but at least we had good seats !

more from the road

Looks like we’re goign out of town again !>. DIane and I have decided to slip in a quick trip to Germany to see gabe and celibrate our 40th Anniversary.   

I’ve been working as I travel.. but some  thigns requitre hands on work… so i’m workign some long hours this week to move soem projects along. 

One back burrner project is to modernize the 1949 windtunnel demo I made for work several years ago. THe windtunnel itself was a phyics demonstrator from 1949. It was goign to be thrown out when UVM merged its phucs lab into one of the CEMS labs.. I was glad to inheret it..

Originally I made a very cool retrofit of the demo.. it used to make smoke by heating oil and pushing the smoke through a bunch of nossels.. 

It was beutifull.. but was a bear to maintain. the smoke gnertor kept breakign down, the smke fuid (pro[llene glycol would condense in the electroncs and tubing.. I was always having to repair it.. I finally had my freind Arlo bring it from work to my shop where its been sitting for al most a year. I’ve tried to find a replacement for the tempramental smike generator.. but anything that involves chemical smoke, is goign to have the same maintaince issues we’ve always had…

so.. ‘m takign a new direction.. my freind Ben at work found a very cool project on instagram by a really smart guy named Cesar Giminez from Brazil . Its a 2d wind tunnel simulator called Kutta  that uses lattice Boltzmann methods to do n approximation of. windtunnel 
it looks like this

You can play with my version of the code online  here http://johncohn.github.io/kutta

So.. my idea sis to run that code on a raspi and embed the screen in the original old device.. 

not nearly as cool as real smoke.. but should be fun anyway !

here[s a quck mockup I did today 

Looking forward to getting that finished  and back in service soon !
