The rest of the cabinets are in the same ply (Keruing, often called carcass ply) with handles routed out. The ply is cheap and has a straight grain so not too busy in the face, but it is open grain so had to be grain filled (used watered down box brush timbermate - weird smell but works well).

Been working on the last bit of kitchen cabinets. Going with groovy doors for the top cupboards. Cut with a 6mm kerf. Just got to sand the other 5 😂

Classic polygonle yesterday. Just needed to reserve the reverse…

It’s got a very retro web interface but can push out to HA etc. Dies the job nicely though, completely consuming what was generated this AM:

Considering solar. We have a chimney and a sewer vent on the north/west roof, so figured I should check the shading by spending too long making a chart. Interesting shape to the shadows across the day. Fortunately it looks like no major shading on panels, so should get good generation.

More twos than threes unlocked on the polygonle🎉 🥳. Am finding it most enjoyable word game at the moment. Requires a bit of thinking time between guesses but satisfying when you get it from only a few clues.

Another idea for #adventofcode day 19. Use a graph with vertices between each letter (and at ends) and edges denoting the towel that links them. Part 1 is just checking if there's a path from start to end. Part 2 is then just counting the paths using (I-A)^-1.

We then just look for another yellow in the drop list that’s a vertex cut (i.e. repeat), and we get this. The vertex cut (red) here is then the solution (yellow is the only route to the end) (3/3).

So need only check the yellows that are on the drop list for if they form a vertex-cut (disconnect graph). This gives the red using the graph from part 1. We can drop everything up to this one (another ~1400 odd pixels), and then check for another path (2/3)

I just had a look quickly it turns out I get the solution by iterating twice. The first is graph 1 with the next input (red) that forms a vertex cut (disconnects graph) and is on the path. The second is the maze up to the first cut with the next input that form a vertex cut (the answer).

Day 18 of #adventofcode is interesting in how the maze gets built out fully in places while other areas remain empty until later on.

Day 16 #AdventOfCode was back on the graph solution train. The trick I used was converting the map to a graph by encoding each reachable pixel as a K_4 diamond connected across valid paths. Edge weights were 1000 around the diamond (red), 0.001 across (grey) and 1 between (dark blue).

Love these negative detail extraction grills. Very tidy finish with grain continuity.

Was thinking the ECTO-1 build was a little less interesting than the Camaro, then they go and use half a technic wheel hub and a goblet for the rear lights! Amazing.
