    Increasing the output voltage of a step-down transformer by reducing the number of coils

    My guy at the shop told me.... More power bigger wire, more current more wraps.

    Fishing bite alarm

    My childhood was spent on a floating logging camp. I learned to fish before I learned to run from bullys. picture a litle kid with a spin caster set that is taller than he is, with a stainless wing spinner triple hook, and a length of sinkers longer than his d***.. life jacket and all, that's...

    Samsung 2017 Smartfridge component missing

    Still missing that curve!!! I found a refridge compressor, that I am hoping will work. Doesn't help my phone issue though!

    Samsung 2017 Smartfridge component missing

    Are there wiring diagrams in the service manuals for these or are they like the 1980's "thats extra" terminators?

    Looking for a service manual / schematic

    By the time you get done replacing everything you will probably realize you should have just replaced the board. Asus are not all the expensive, and although you will be faced ultimately with the same failure, swappping out 120uf caps with 150uf caps is not a good idea. I would say its...

    arduino uno R3 schematic and datasheets

    "Anybody can build one..." one week later... " There is a guy in the Caicos that builds them, just order one".... Quote from my first electronics teacher... 1978

    Samsung 2017 Smartfridge component missing

    yeah... well those phones with cameras are called smart phones, and mine is starting to act like my smart fridge...(needs things someone is hoarding for themselves)... yur not a hoareder err ya??? didn't think so! When my phone cam starts working again there will be photos... ok! until then...

    Samsung 2017 Smartfridge component missing

    I want to build this old free fridge into a smart kegger fridge. It has 4 doors, and is perfect for what I want. It was free, and when I opened the back it has 3 circuit boards, and two protruding wires that must have connected to something. Trouble is, I don't know what it is.... a smart...

    Electric circuit problem

    This circuit looks like an amp stack. Problem with that is that no matter how much power you put in, it only travels down the POLR. You have to use the power you make, or it causes everything else to heat up.

    POT burning/candle-like smell

    Maybe you have the wires connected in the wrong polarity. Reverse the current. pots are bogus. I hate them. First you are trying to run a linear projection on an oscillator device, it just won't work. Electricity only travels in one direction. The word oscillator is used to identify circuit...

    Cold Smoker blower

    I built one. I took a 2" square steel tube and cut about 7" off of it and welded it to a 2" flat bar. Drilled a 1" hole in the front side about 2.25" from the plate. Then I cut a 1" square steel tube at a slight angle to allow for exhaust and welded it over the hole. Then I drilled another...

    holder glues on cheap boards

    Those silicones attract static electricity... I was shocked numerous times when I was caulking in Alaska. I didn't figure out shat it was until many years later. I don't really think silicone is a good idea either.... (I was born in California, cyanongens cause cancer...) what about JB weld...

    Astable multivibrator circuit making me astable

    Physicists and Inventors have argued about this for a long long time. Inventors worked out the numbers, but the phycisists built the device. The fact is that if you don't know that the amount of draw that circuit has running through it, then any device that can do the job will. (complete...

    holder glues on cheap boards

    holder glues on cheap boards

    I have seen a lot of pucky on boards, and I also have removed some things I thought were melted holders or clamps or supports that I thought got hot. I fixed my battery issue on my SD-1 Synth and put a battery holder on it so I don't have to do any soldering when I change the battery. The main...

    Potential energy of suspended mass expressed in kWh

    I think the lesson here is superfluouse joules! That being said, only a gravity in the force can keep the ship stranded here, and when they release that piece of aluminum sheet, be far from the direct path of its travel....please.

    Which Arduino motor control?

    Springs and Weights... and use suitable levers with 0 zero tolerance to maintain a device that will last a long time. Anything that moves, wears out eventually. So if you can build a motor support that has buzz nullifiers thats a good thing. Bumps, vibrations and shakes all play a role in the...
