Welcome to the video course on 1-9 Basic circuits: Logic gates, flip-flops and latches. In this video, I will talk about some logic circuits and basic memory circuits.
For simplicity, the effect of input bug is to be ignored in all introductory courses.

This is a tiny 2x2 sticky piston-less door which is inspired by MundM2007 and is built by me.
I have noticed a few improvements that could be made in the tutorial section so I changed the format a bit for easier reference. Let me know if I should keep the changes or stick to the original one.
Again there is no audio for this video, and it would probably continue for a while. Sorry about that.

![1 wide Seamless Hiidden Wildcard Crafting Table [Tutorial]](https://i.ytimg.com/vi/tU72tet6FDA/mqdefault.jpg "1 wide Seamless Hiidden Wildcard Crafting Table [Tutorial]
This is a 1 wide seamless hidden wildcard crafting table which is built by me.
This contraption/idea has recently been a popular topic/build in the redstone community so I made my own attempt.
Please note that for the block that is put into the minecart, it must be done the way shown in my video (i.e. using a sticky piston and a lever/button activated on the side/top/bottom of the piston, or you can 0-tick the sticky piston in any way).
