And thanks to our new Swedish overlords we have some tap to open magic for the bin. Uses the UTRUSTA electric opener from IKEA. Manufactured by Blum and seems identical to the Servo Drive Uno for 1/3 the price.

Finished up the kitchen. The grooved cupboards turned out pretty good and am happy with the ply mitres which wrapped pretty consistently. Ply is Keruing (Brownwood) from Plymasters.

Over $1k savings now in less than 6 months with the solar. Around half of that is due to export, the rest self consumption mostly by time shifting the hot water.

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.
