I am ditching Spring because of fast rising prices matched by an equally fast declining quality. The Spring legacy store is still up so you can still buy from there if you wish
Actually, just the links for the stuff I use in the lab that I have found to be useful: tools, components, glue, and associated weird stuff that's difficult to find yet so useful. The channel gets a small commission if you buy from the link, but it costs you nothing more.
Note: This site is always under construction... I often implement a page when someone asks for more detailed materials about a video. Just ask in the comments if you need more info, that will give me enough incentive to complete the relevant page!
This will give you a flavor of what to expect.
