What Active Components Do You Need? - Workbench Wednesdays

Active components like transistors, BJTs, MOSFETs, and integrated circuits (ICs) make it possible to control circuits. This video explains the must-have NPN and PNP BJTs. For MOSFETs there are a couple of N-Channels and P-Channels to consider. Basic ICs include some digital logic stuff from the 7400-family as well as the venerable 555-timer to have on-hand. We did not forget Op-Amps either. Spoiler: We do not recommend the ua741! bit.ly/34Y7Ba1

Good video, op amps are a lot of fun. I don't get why the 741 is in all the beginner tutorials either. I like the LM358 and other single supply op amps much more. I enjoyed buying a kit with a number of different op amps, and learning about their differences. Most beginner tutorials don't even mention that op amps come in a wide variety. I also really enjoy having kits with a bunch of different 7400 series integrated circuits to learn about and try to make interesting circuits with.

Oh class I didn't know you could get an LM317 in the TO92 package. I'm definitely going to look for them on my next parts buy. AWESOME

I also might add its absolutelly essential t oalways buy spares for whatever component you need, you WILL loose them or RUin them or need it another time. So get a handfull of each. and after a while you build up an arsenal of usefull stuff automatically... I don't have an electronics hoarding problem....really.. I neeeeeed all those reisors and ICs and stuff

[@keithking1985]

I know what ya mean there. But it's I good addiction to have. (Like it's not going to kill you,... unless you touch your high powered project that's still plugged into the main) then you you should be fine & keep collecting.

these are so helpful to us just starting out! thanks

[@ESTEBANTMAN]

I consider optocouplers essential too, for example, the 4N25

Good sir

[@tonAnTv]

The transistor question was a total setup.

[@bald_engineer]

I got the idea after seeing a video about MOSFETs where it opened with the same question.

Very

Let's do everything using DSP processing and FPGAs and firmware written in C++ using a compiler for the TI range of DSP processors and a compiler that can turn a circuit diagram into a file for loading into a FPGA, can't we not use a NE556 as a PWM modulator driving CV pin of the NE556.
