Hi there. Sorry if you see this twice. I'm very new to the hardware side of electronics. After I posted the first time, I was going back through the schematics I drew and the XOR wouldn't work (I left out a resistor), so I got confused deleted this post because I thought I had this one wrong, too, but I didn't. I've watched all of this Transistor series. It's really good. All I had were NPN transistors, so I made both the XOR and XNOR with 4 NPNs. From your comment about diodes, I realized I did need a diode for the XNOR to keep the NOR gate from pulling the AND gate down. I learned a lot from your videos. Thanks for making them.
Hello and thank you very much for your comment! Sorry it took me a bit to get back to you. I unfortunately didn't manage to experiment much with diodes for this series (it took me a while to get the basics intact with just the components used here), but that does sound interesting and I'm glad you got it to work =)
Nice work and explanation. Would be cool to see a CMOS or JFET version if you do a revisit since they make better switches. Just not as beginner friendly.
Hello and thank you for your comment! I did not properly calculate resistances. You should not follow these values. But I used 10kohm resistors on a 5V input.
Hello and thank you for your comment! For this series, I used: PN2222A NPN Transistors, and PN2907A PNP Transistors However, don't take these videos as an authoritative guide on how to use these particular transistors, as I'm doing everything intuitively and may have inadvertently violated the best practices for using these components.

Hello and thank you for your comment! Yes, I wasn't confident enough for that which is why I didn't broach those topics. Maybe one day!
Hello, what's the program you use in this video?
Hello and thank you for your comment! The software used is Logisim: www.cburch.com/logisim/
Please share the values of resistors and power supply
