Keeping an Eye on the Robots

I've been going through the world of FIRST robotics trying out every job.  Judge, Field Reset, Referee, at the lower levels I've done a bit of MC work.  At this event I'm a Robot Inspector.  You have to ensure that the teams comply with all sorts of rules.  I try to be supportive, yet steely eyed...


Mostly fun, I've not had to admonish anyone to any degree.  But after hours of digging around inside robots....


Not sure how my team will do.  There was an unfortunate storm system that came through and closed school for the day.  As a result the team was not allowed to travel even though by noon it was quite decent outside.  This puts us at a competitive disadvantage.   No practice rounds for us on Thursday night, no field calibration either.  We'll see how things go.....

Tree Shaped Tombstones - some Jewish examples from St. Paul. And from Vulcan.

 Tree Shaped Tombstones are not evenly distributed among different faiths.  From my extensive - if unscientific - study, I'd say they are more common in Catholic cemeteries and leas common in Protestant ones.  Jewish cemeteries are scarce in the Midwest, so I don't have a big sample, but today we'll visit three of them in St. Paul, Minnesota.

Due to a mix up in directions I started out at Mount Zion cemetery, it is the burial ground for the oldest Jewish community in the state.  The Temple goes back to Territorial days, but the cemetery has only been in this location since 1888, but had only a single "tree" and not a very interesting one at that.  But a few blocks away at the adjacent Sons of Jacob and Sons of Moses cemeteries it was a different story.  Despite having examples that were mostly from the latter days of Tree Shaped Tombstones, there was a lot to see.

Some features of the tombstones I saw here were unusual.  Many have details beyond the name of the deceased.  Beloved Daughter, even in abbreviated form, is poignant.  This low "book style" with Hebrew on the left side was pretty common.


Here's another one.  Note the interesting hands on the otherwise drab tombstone behind and to the right.  That will become important shortly.


The odd little niche down below also caught my eye.  What used to be there?


The cemeteries are in part on a hillside.  Scenic, but not ideal for tall, heavy tombstones!


This last picture was obviously taken on another day.  Even in the Midwest weather does not change that fast.


Notice the hands?  Those are Cohen Hands.  They indicate that the person, it has to be male btw, buried here is a descendent of Aaron, brother of Moses.  This illustrates the hand gestures made by Jewish priests (Cohens, or Kohanim).  While this indicates a priestly lineage it does not mean the person buried here was a priest.  Or even had the surname Cohen or its variants.

In a bit of trivia that I just learned writing this, the gesture - separation between ring and middle finger - inspired Mr. Spok's classic Vulcan salute.  Leonard Nimoy was of course Jewish, and made up this bit of Vulcan culture based on what he'd seen in Temple as a young child.

FIRST Robotics 2026 - The Meg 2.0. And interviews with people and inanimate objects....

Our robot, The Meg, got a lot of things right.  That's why we started our recent event running off a 9-0 streak.  But after that it got a little tougher.  So we had some things to fix...but not - as in years recent - a full rebuild on our plate.

Let's start with a new "nameplate".  It is also our main crash bar for front impacts.  It is now both stronger and scarier looking.


Various other tweaks all happened in rapid order.  The goal is to even out power draws. In our last event there were "brown outs" that in particular impacted vision targeting.  

Fun video from our last tournament.  A mix of Meet the Robots and Asking Odd Questions:


In keeping with the short deadlines, fast turn around of FIRST we are heading to another tournament later this week.  Much more on this in a few days.

Oh, I can't resist.  Here's a quick peek at the upgrades, which include teaching the robot to actively resist being budged by defending robots - or interfering humans - once the targeting cameras have the launcher spun up and ready to go....

Tree Shaped Tombstones - Merrill Wisconsin

Merrill Wisconsin has an odd history.  It was founded very early for our part of the world..late 1840's.  But it was basically just a logging camp at the time.  It did not turn into much of a community until the 1880's.  Still, plenty old for it to have the Tree Shaped Tombstones from the late 19th and early 20th centuries.

Earlier this year I was up there for a hockey tournament.  And I did find a couple. Both oddball specimens.


This thing is just plain ugly.  Drab color, which the drab winter day does not help.  Minimal structural features.  The surface texture is not the ridges made to look like tree bark.  I'm not sure what they were going for here.

I think this is some kind of low grade marble.

It really just has a bunch of poorly defined leaves and vines on it.


The next example is of a form I've seen many times.  The stump with two branches.  It usually is for a married couple, but only the man's name is on this one.  It also has a metal plaque.  This is more common in the southern US from what I've seen.  Odd ball up here.




Nice copper oxide leaching out from below the metal.  A reminder that archaeology is not far off, and that my eye must be tuned to this color spectrum.

The Private Life of Beans

When I was gifted 30 pounds of dried beans for Christmas, my expectations were modest.  "Cool beans", I obviously said.  And hoped that perhaps they'd be of some use in our hunting land feed plots.  Deer will eat dried beans, tender green shoots, etc.  

So the basic plan was to just plant some in areas we turn over with the neighbor's tractor.  But it seems I had set my expectations too low.

Catching up from previous postings, I:

- Planted about 10 of each variety.  50%-70% survived my indifferent care

- Transplanted one of each...except for one variety where two were intertwined.

And the darn things kept growing.  This is a picture from March 11th.


They were supposed to be bush style beans, but weirdly turned into vine types and proceeded to climb 3 feet up the window blinds.  Had I known this in advance I would have added some stakes.  And perhaps set them up somewhere else.

But its nice to have a bit of greenery in late winter.  Sometimes I remember to water them.  Usually its when I finish a cup of coffee and use the empty cup to fetch their ration.  Caffeine traces might have something to do with their vigorous growth.

But something else is happening.  

I know very little about the sex life of plants.  I actually don't care to know more.  But I vaguely recall that in the whole "Birds and Bees" scenario there should be, you know, bees.  Or some other way to pollinate flowers.  Oh yes, there are flowers.  All three varieties of beans, with various small yellow and blue blossoms.


And there are beans.  Yes, I am officially a bean farmer now.  


This is unexpected.  Oh, we are only talking three that have reached the stage where actual beans should be forthcoming.  Several more adorable little mini pods may or may not develop.  But this shows a degree of resilience that I had not expected.

So how did this come to pass?  Well, some plants are rather ambiguous is such matters.  Male and female parts on the same plant?  I guess.  Pinto and Navy bean hybrids?  Sure, why not.  Heck, the hops that I planted years ago on the back fence just up and changed, one section of the hop producing female plants just throwing some sort of biochemical switch and converting to male hops.  The latter btw are not productive of anything useful to a home brewer.  And, to be frank, the female plants were plenty productive before this transition.  Probably there were bees involved.  Birds can't be entirely ruled out.

So now what?

It appears that free, dried beans can turn into deer pleasing snacks with a fair degree of success.  Oh, and with potting soil and an absence of rodents, turkeys and such to nip them in the bud.  Or in the pre-bud stage.  But it encourages me to try the mass approach.  Every week blast another 10 or 20 pounds of dried beans off into patches of recently cleared land.  See what happens.  Most will get eaten right away.  Some as soon as they dare show their tender little sprouts.  But evidently beans are scrappers, they'll give it their best try.  So I hope to be looking out across waving fields of tasty to deer plants.  At which point I'll tip my bean planter's hat and say "You guys/gals just do your own thing out there.  You be you."

FIRST Robotics 2026 - Tournament Number One

Off with the team to Appleton Wisconsin for a long, tiring weekend.  It's a three hour drive. 

A successful outing that proved the merit of our design and construction, and showed off what a group of talented kids can accomplish with hard work.  We astonishingly started by winning our first nine matches.  This has never happened before, and statistically may never happen again.

By the end a bit of wear and tear was showing, so our time in the double elimination final rounds was short, but for a first event it was excellent.  We have a limited amount of time to repair, recharge and in selected cases upgrade.  We are off again in about ten days.  

As usual, some oddity photos.  I'll try to add a link to our matches when it becomes available.

This event was in a big high school gym.  It's actually nicer than some of the arena type venues we've been in.  Maybe you can feel a bit of residual energy from generations of kids excited about things going on in front of them.

Our driver actually seems a bit pleased with the damage our robot's name plate took in an intense match.  


There are as always little event freebies.  In keeping with our school mascot we had these little plastic cardinals.  Somebody arranged them in this pattern.  Various stories were concocted about what was going on here.  Some were a bit dark, court martials and such.  I suggested the vibe was "Teach us oh Eldest and Wisest".  But maybe I was projecting.

Not as many mascots as in earlier days.  Those suits are hot and awkward, so when you do see them it is towards the end of the event.  I of course had to ham it up with a couple of birds.  It's me doing my best bird imitation.  It's not very convincing.


More to come.

Robotics 2026 - Off we go!

A final afternoon of tune up, tweaking and then packing the trailer.  It's great to be packing in shirt sleeve weather!


Not like last year.....


This was a silly photo I took prior to our departure to a tournament at about the same time in 2025.  And boy, howdy, that shovel was a handy thing to have around.

But this time, while the drive will be longer the weather looks great.

I'll be banking some extra sleep hours.

Team is competing in the Appleton District event.  If interested you can follow the results and  watch our matches at:

We'll see how it goes......
