    How can I make an oscillator with 3 capacitors?

    I need to create an oscillator circuit that works like the following: There are 3 capacitors of equal value. One capacitor charges until it reaches a threshold voltage, and then it is instantly discharged and then the next capacitor gets to start charging. The cycle continues. Only one...

    Atomic Clock disciplined with Rubidium

    Good day thread, I was able to get my hand on a FEI-5650A Rubidium Frequency Standard and I was wondering how I could use it to make a really overpowered wall clock. I was able to power it using some information I found on the internet from a defunct website. Using an oscilloscope, I was able...

    555 timer frequency

    I have a steeper motor that needs a slower step-pulse to get it moving then a faster pulse to increase speed. It needs to start at 1.25hz then increase to 10 hz in a short amount of time. The 555 circuit will be powered on with a trigger limit switch. Then unenergized once the stepper motor...

    USB Charger Circuit - Initial Consumption Before Power Negotiation - Timing?

    Hello, I have a voltage regulator (switching & boost regulator) who's output voltage is being set/controlled by a microcontroller. I can set the output voltage to anything between 4.5 volts and 6.5 volts. Under normal operation, the voltage is always going to be between 5.2 volts and 6.5 volts -...
