    I want to know all of the maths concerning this scissor mechanism!

    6 My good man I have given you the foundation to which to build upon. It is straightforward! Nevertheless I will try to break it down for you even more. I'm on break I'll see you at lunch.

    I believe the moderator, Mr.Harald Kapp nailed it! You just repeated what he has stated. Make,model number,link of your two battery powered boards with onboard charger?

    Be careful! Error in Scissors Lift Equations?? 7.12.2012 Update: Ok…. finally Engineers Edge has corrected their equations. So I have modified this post to take out the obsolete references. https://vamfun.wordpress.com/2011/11/12/error-in-scissor-lift-equations-at-engineers-edge/

    No Output Signal from H-bridge driver IR2104

    Yes you are missing something... First of all this is an H-Bridge. H does not stand for half. Your circuit is a half bridge. Should we check your settings in proteus? What are your settings? Is this homework?

    Issues with connecting an electret microphone to a recorder's phantom power.

    Respectfully Yes you can measure it with a digital multimeter. you just don't know what you're looking at or what you're measuring. Chat GPT? That is the dark side... The revolution has begun.:) The schematics provided in the PDFs especially Texas instruments gives a "Prime"example but if you...

    Power Management IC - Assembly issues

    Also altitude, along with combinations of various alloys to suppress said whiskers but to no avail.Excellent subject for research and experimentation especially if you're into metallurgy. I would look into the type of solder you're company purchased. If you notice this right after the...

    Varistor? Help ID Component

    It could be a black dot or a portion of the top of the capacitor is black indicating it is a NPO ceramic disc capacitor. Meaning negative temperature coefficient is 0 at room temperature. It is used in circuits where frequency or timing accuracy versus temperature change is critical, such as RF...

    Varistor? Help ID Component

    That is a 10pf capacitor. pico farad capacitor. Rf baby. And by the photos that's the least of your problems I doubt that capacitor failed. Show me! I have identified the component for you. Now I'm willing to troubleshoot the board for you. What does it do what does it not do! Perhaps we can...

    Varistor? Help ID Component

    I do have a crystal ball but it's buffering right now. Photos and of the component itself, what device did the board come out of? Make, model, serial number, perhaps I can find a schematic. Geez:)

    Scrub -washing machine malfunctioned

    This is what may happen. Get yourself a new cap. What's a scrub-washing machine? Does it really have scrubbers on it? Or does it just agitate and spin¿

    Issues with connecting an electret microphone to a recorder's phantom power.

    What about the voltage on the hot side pins one and two both cold and hot have a 6.8 k resistors. E =IR there is your voltage drop. Below is a good read...

    Raspberry Pi execution on power on.

    Well let's see, I searched quoting your query... Add commands to the file rc.local to run a program when the Pi boots. This is useful for headless mode, where the Pi is powered up without a monitor, and runs a program without configuration. :p
