that is cool but how do you buy the components
The feature to buy all components seems to have changed recently. A few days ago there was a tab that listed all the parts and their prices, with the option to buy them via curcuito.io. I suspect very few people did this because the prices were sometimes multiples of the Chinese import prices. The parts can now be purchased individually from DigiKey by clicking the Buy button next to each component in the list that appears when you click Parts in the top right:
The pound is currently worth $1.29 so that’s $2.80 from China vs $22 from DigiKey. I think I can wait for the free shipping from China.
