    Thank you!! I have been trying to build my first 555 timer circuit, and couldn't get it to work, until I hit your video! MY LIGHT DAS BLINKEN!! GOOT YA! hahaha!! And THANK YOU for explaining that I can change the capacitor to change the PWM signal! I'm getting smarter, thank you! :)

    Thanks Paul, really useful again! I have a particular problem - trying to power my WSPR transmitter over a 2-3 day period with a modern USB power bank . Problem is my supply keeps switching off. I'm assuming that if the power bank doesn't detect a certain level of current draw, it switches off the supply to the USB port. In my case after 30 seconds. Is there a possible use here for the 555 to switch on a load drawing say 50mA, every 15-20 seconds?

    Every demonstration that I see today utilizes LEDs. I'm trying to build a multivibrator for small 1.5-3v incandescent bulbs (powered with 3v-9v batteries) to restore some old toys that require vintage bulbs.
    It seems that incandescent bulbs have far more resistance than LEDs. I made the mistake of purchasing some prefab multivibrator PCBs for LEDs (because I have no knowledge about this realm). The setup was rated to handle 3-15v, so I thought that this would be great for powering my micro 3v lights. The default PCB setup wasn't powering my incandescent bulbs. I was told to remove/skip the resistors leading up to the diodes, and wire directly to the incandescent bulbs. This hack works, but this hack is not really the solution that I want, and it's overloading the components (transistors are quite hot and eventually failed). I'd much rather know how to select components that are correct for the job, instead of banking on the supposed workable range of a default product.
    Is there an easy way to check the resistance of a bulb (if heat from a bulb can cause varied resistance)? How do I build a reliable circuit that will power them? Someone suggested that I use a 555 timer instead of trying to balance a mutlivibrator. :/ And as far as a 555 goes, I have no idea how items should flow through the chip.

    first of all, thank you for all your videos. even if sometimes my level is too low for what you say, i learn little by little. thank you. u mention that the ne555 kind of debounces the button. i liked that because i need a hardware debouncer for a non arduino project (already watched you software debouncer video amd it was primo). would you let us know how to use the ne555 as a simple button debouncer. thank you

    Right on. I should have learned this first before I started trying to play with these. I have this 555 memorized now. Shoot I can make my own projects instead of trying to figure out what went wrong. If I had watched this. It would never have taken me as long to figure out some of my 555s were bad out of the box. Thank you.
    Or are they bad? I have not used the reset. Hmmm? Now I'm wondering.

    is there a 555 timer with two output pins and can you make one output pin low when the other one is high and have the two output pins alternate at desired frequency with var resistor? and cap ? , i need it to trigger two transistors ?

    • @takix2007
      @takix2007 3 года назад +1

      Maybe use a PNP and a NPN transistor, both bases connected to pin 3 of the 555. Then, when pin 3 is high, NPN is "on", PNP is "off", and vice-versa ?

Just a suggestion for continuous improvement. But please don't go so far as Great Scott! in terms of pace. I'm a sub of his and like the channel but need to pause constantly...he just goes too fast! I guess the middle way is desired by your viewers. Easier said than done, I know. Whatever the case, thanks for your making these vid's!
