In small, discrete quantities, transistors can be used to create simple electronic switches, digital logic, and signal amplifying circuits. Discrete NAND Gate Nand Gate, Computer Geek, Circuits, Logic, Geek Stuff. So the challenge is, does any one have any nice discrete transistor toggle circuits that:Ī) Use minimal components as my sons patients for building things is a bit short at the moment.Ĭ) Runs from a 5 to 6 volt supply, dictated by our rechargeable battery pack.ī) Can be easily understood by a 12 year old beginner. In this e-learning course, you will learn the definition of semiconductor and the basics of semiconductor devices, including diodes, transistors. of electronic devices and appliances, including televisions and computer monitors. I have seen toggle flip flops built with two transistors, caps accross the base resistors and a parallel switch resistor connecting the emitters to ground (as here ) Fine but I would prefer the input to go into some more normal place rather than brute forcing the negative rail up and down. Left to themselves, discrete transistors are typically not toxic. Years ago I did this by using two flip flops wired as a master and slave but this solution required many transistors and I'm not sure I could reproduce the thing anyway having hacked it on the fly at the time. His question now is how to make a bistable flip flop with only one switch as input that toggles on/off each time the switch is pressed. My young son has just been building a two transistor bistable (set/reset) flip-flop and the standard two transistor astable flip-flop (flasher) with a couple of LEDS in each. ![]()
