[TriEmbed] Pinewood derby help

[Craig Cook]

Ah, learning more.  This is the project I am looking at:


https://chip.hackster.io/user024507/motor-on-9c6bd1?ref=channel&ref_id=5276_trending___&offset=22
Is the 2N3904 working as an isolator?

The donor truck contains these:BR8550D 064 (x 4)C1815Y 5LSuper Chip STRX3A, 60100395

Could I reuse the C1815Y for my isolator?

I also have these new PN2222ABU, BC547B, P2N2222AG

I could attach a picture of donor truck board, but it would have to be less than 100k.
Thanks
Craig

Yes, you will need something like a MOSFET to handle the higher current that the motor will draw and a different power souce that what is being used for the CHIP, but that won't isolate the motor from the electronics. You will still need an opto isolator.
