Try searching for "coreless motor", gives me lots of ebay results with tiny 7mm diameter dc motors looking like this: https://external-content.duckduckgo.com/iu/?u=https%3A%2F%2Ftse1.mm.bing.net%2Fth%3Fid%3DOIP.0qbVZk69iUxzXpp-87VHFwHaHa%26pid%3DApi&f=1&ipt=34626bb8832b480226ede8e0a44a8013a56d9217b7cb576ec699024a06297899&ipo=images
Afaik that's a myth. There is no testing or certification associated with the CE logo, it's just a self-declaration of the manufacturer that certain standards are met. You can just buy rolls of these stickers, or print them yourselves. That's what manufacturers do, legit ones and shitty ones.
Nice, than you for sharing!
I won't be using this for my measurement issue (the other options are much simpler, and i was aiming for less parts, not more), but I'll do some experiments to familiarize myself with bootstrapping
Hm, I don't understand how this is supposed to work - is that a n-channel or p-channel FET?
When I sketch it using falstad's circuitjs, it looks like the FET (n-channel) is a little bit on all the time
and fully on, when a pulse is applied
