I just pulled the trigger on a 01 gram hario...

Will zero the scale with my filter wetted chemex on there and pour the coffee into it from the baratza bin until it reaches the right weight and then add the water using the kettle until it reaches the right weight again. I thought about the baratza scle but it is expensive and then only useful for coffee whereas this scale will work for any cooking or postal needs.
I also ordered a stainless baster...

Thinking perhaps I could do my drip using this instead of the kettle dipping it straight in the Zojirushi after boil which would heat the stainless up and act as an insulator during the drip. might need 3 fills of the baster but would offer perfectly controlled delivery down to the drop. Was also cheap. If that experiment doesn't work I will use the kettle and still have a nice baster for cooking.
I will be interested in your thoughts and opinion of that Hario scale after you have used it for a while. I considered buying that model to weigh tea and also do coffee pour overs with optional the accessory stand. The scale + stand package looked functional and nicely paired together which is what drew me towards it, but I did not really need it, so have not purchased.
If you get the Hario kettle that you mentioned before, I doubt you will find any need to use the baster repurposed as a dripper. Unless you are careful I would expect the baster to release water with more force, more than the force of gravity which will agitate your coffee bed too much. Sometimes you might want extra agitation, but in general I have found that minimizing the agitation or stiring of the coffee bed while drip brewing improves the taste.
