Really cool! I learned about flip flop circuits on this channel. I created a soldering practice board using many parts to allow folks to learn the basics of this circuit using capacitors, resistors, and transistors to alternate two leds. Hoping to further folks knowledge of basic circuits while getting some practice. Thanks to Imsai Guy! Sharing what I’ve learned!
Another cool feature of 4000 series CMOS devices is that they can be used in negative supply circuits. That is, high = 0V, low = -5V or -12V or whatever. May be useful when they are combined in analog circuits. This is how CMOS is used in my HP3465A DVM that I recently repaired.
At the begining cd4013 is compered to 7474. Its not just the pinout is diffrent. Its diffrent tecnology. 7474 is TTL and cd4013 is CMOS. the idea is the same but voltage level is diffrent because of thechnology.
Ahhh the good old 4013 flip-flop. Q follows D after each rising clock pulse......one of those things you'll never forget. Great for easy divide by two.
That is strange. The datasheet for the 555 specifically states timing is independent of VCC. Plus the formulas for calculating high and low times do not include VCC variable in them. What is your 555 circuit configuration? It must be a non standard circuit not specified in the data sheet. Great topic for discussion for chip of the day.
it does not include negative Vcc. some use them (as you can normal TLL) with Vcc tied to ground and the IC ground tied to a negative voltage. the IC thinks it is just normal

A favorite for many politicians.

the Arturia Mini/Micro Brute also has a cd4013 on a negative voltage, i also run 2 DIY eurorack modules using a cd4013.

Changing 555 voltage..,causes change in on & off time i.e. the
osc. frequency... but the Duty Ratio does not change......
... or being used as 1 bit ram using set and reset. very versatile chip.
Great video, thanks
Ah, the cute 4013.
In my last design I use it for phase comparator in cosφ maximizer circuit.
Nice. Back to the basics few people learn nowadays :)
So, divide by 2?

you are right, I have a bunch of 555 modules that do this. I'll make a video
So to check my understanding, cmos operates over wider supply ranges, including negative Vcc. Did I miss anything? Or goon anything up?
it does not include negative Vcc. some use them (as you can normal TLL) with Vcc tied to ground and the IC ground tied to a negative voltage. the IC thinks it is just normal
Do you have a CD4047B Astable/Monostable multivibrator? It's nice for square waves in place of a 555, automatic 50% duty cycle.
I have to ask - what are these little breadboard modules you’re using for clip-on power / GND and the 555 module ? I want these !

search ebay for the 555, lots to choose from
Good on ya IMSAI Guy yay:)
As a suggestion, would be more informative if you spent some time explaining connections to chips and test interments.
