[IMSAI Guy] got some fake LM358 op-amps. Uncharacteristically, these chips actually performed well even though they didn’t act like LM358s. [IMSAI Guy] did a video about the fake chips and someone who ...

Sometimes you want to have specific modules in your lab that are not available off the shelf — a compact DC dimmer/regulator module, for example. That’s why I decided to develop my own module, which ...

This is a circuit in which LED glows slowly in the beginning, then grows brighter and once again slowly it becomes dim. The basis of the whole circuit is an operational amplifier IC named LM358. This ...
