Hi thanks for your input. That other thread was interesting as well - i liked the idea with the sprung weight. That concept was new to me. so i removed the keycapps for the word "house" and weighted them with my pretty fancy scale. But i must say my scale is not optimized for weights under 100g (it weighs up to 3000g so it might not be superacurate in those weight ranges) Here a the results:
TECK: 4,6 total, so 0,92 g per Keycap
Cherry Mx board: 3,9 g total ~ 0,78 g per Keycap
Could this cause this difference? That would be crazy if one could feel this difference..
