An Aeropress. I bought it when work removed the free coffee and was super surprised at how good it tasted vs what they were serving. Later, I found a bean hand grinder that fits right inside the Aeropress plunger and now I take it on work trips, vacation and camping.
It’s not fully inclusive for $20 because you need a cup, some way to procure and heat water and beans but still, it’s served me well.
This worked well for me when I could see the screw and it’s orientation was the same as me viewing it. If I was turning it and it was rotated 90° away from me, I’d get it wrong. In physics class, we studied electromagnetic forces and I learned about the right hand rule which for some odd reason works better for me than righy-tighty. The Wikipedia article is long and the TL;DR is that if you use your right hand and turn in the direction of your fingers, the screw will move in the direction of your thumb.
Of course lefties are SOL as are folks without thumbs.
I use OSMAnd+. The searching is the biggest problem, so I will contribute to StreetComplete in an effort to improve the areas in which I travel.
When I do need a location that isn’t found in OSM, I’ll grab the coords from LatLong.net and copy/paste them into OSM. When I get to the destination, I’ll pop open street complete and fill in details in the hopes that next time will be better.
I have an old one, maybe they were manufactured differently. The main part is a hard plastic. I never noticed a plastic taste, but it could also be the rubber/silicone plunger stopper that imparts a taste. They do now sell a glass one, but I’ve heard that it’s overpriced.
I know people who also swear by their French press. From what I know, regardless of the brew method, the grind is the most important factor, followed by the water quality and temperature.
