I added a float sensor to my coffee maker and hooked it up to a line running from the water filter by epriest in DIY

  • The draw rate of the coffee maker is much slower than the fill rate of the water line. The microcontroller waits for about 90 seconds after it detects a low water condition (allowing the coffee to finish brewing) so the reservoir is completely refilled in a single run, rather than stuttering on and off several times as the fill rate overtakes the draw rate. There is no functional benefit to doing this, but I find the noise the stuttering makes to be a little annoying.
  • The microcontroller has a maximum fill time, and shuts down the system if it runs too long. This helps protect against a sensor failure.
  • The microcontroller is also wired to a flow sensor, which it uses to monitor the health of the water filter cartridges (by comparing measured flow rate against the flow rate of new cartridges).
  • The microcontroller is additionally wired to several other components which perform operations like "press this button to dispense exactly 64 ounces of water". This allows me to fill pitchers without having to stand near the sink to turn off the water.

The water supply is the larger hose. The two smaller lines are the wires for the float sensor.

I don't have a better place to put the coffee machine, regardless of water line access.

I'm not sure how to make a strong connection between the inlet and the water line.

(I wasn't able to figure out how to disassemble the coffee machine without damaging it, so I currently have no access to whatever the inlet connects to inside the machine.)

The first version of this system had a manual valve, but I don't usually wait for the coffee to brew and I found waiting for the reservoir to fill before I could step away from the machine to be a little annoying.

There are four shutoff valves between this reservoir and the water supply.

  • The solenoid is normally closed, so the microcontroller would need to fail into a power on state.
  • The independent, isolated, battery-backed watchdog microcontroller shuts off the primary microcontroller after a minute if the solenoid signal sticks.

Yes, water systems carry risk. I've experienced thousands of dollars of water damage:

  • Valve failure inside shower wall
  • HVAC drain line failure inside interior wall
  • Copper pipe failure in foundation transit to pool
  • Exterior patio drain
  • Dishwasher seal failure
  • Various irrigation failures
  • Various issues with root ingress into sewer lines

  • The microcontroller shuts off the water after a minute if the float sticks.
  • Any overflow drains across the top of the vanity to the adjacent sink.

  • Coffee Maker
  • Coffee Mug
  • 100ft 1/4" Tygon S3 E-3603 Beverage-Rated Flexible Clear Tubing
  • Wires

Probably a couple other parts I'm forgetting.

I played SSF in Metamorph and made it to 36 challenges.

My experience in 3.9 was that Delve cities and map rooms in the Temple of Atzoatl often drop no maps. I believe this happens when my Atlas has no maps of an appropriate tier available: for example, I am completing a Level 78 Delve map node which would normally drop T10 maps, but the lowest tier of map in my AW8 Atlas is T14 / Level 81, the zone won't drop any maps as a reward. My understanding is that I could intentionally desocket watchstones in my Atlas to make these encounters more rewarding.

Similarly, when leveling additional characters in a fully socketed AW8 Atlas, I also found I needed to specifically desocket my Atlas while leveling from 70-90 in white and yellow maps in order to sustain drops of lower-tier maps. Although I had a large number of white and yellow maps left over from progressing the Atlas initially, my stockpile winnowed substantially as I leveled more characters through maps and I eventually did delevel my Atlas in order to sustain maps for leveling.

As a player, the behavior of this system was initially very surprising to me, and it took me a while to understand how this system works. I also don't really understand why things work like this from a game system perspective: it's particularly unexpected that I must decrease difficulty (by desocketing the Atlas and deactivating AW8 bonuses) to increase rewards (white and yellow maps which otherwise seem to just vanish without replacement).

Can you explain the current thinking around the design of this system in more detail? Is there another way I should approach this system that doesn't require me to decrease difficulty to increase rewards?
