It’s been some work to make this happen but finally the shop is open! You’ll find the discussed LogicSwitch from there with worldwide shipping. More info about the product itself can be found in the original idea and the schematic for the new improved version for sale.
At the same time I did some work on site, mostly on the navigation. Reader now arrives to a home-page and blog is available via menu. Also added the shop in the navigation bar.
As usual, if there’s anything you’d like to tell me please do!
