    capacitor replacement help

    I'm sure there is a reason they put those 80uf caps in there. Either the speakers they used were seconds or cheap because someone scrimped on the amount of coil they should have, or they are multi speaker cabinets that have un-matched speakers in them and they had to stabilize the signal enough...

    what mosfet to use for an induction heater

    Get one that is not effected by field radiation. Some new transistors are designed to fire when a field is a certain strength. heat is often produced by humoring the professor...

    3 jumper pinouts on R3 Arduino Uno

    Planets are for engineers, the rest of us live in a world with variations!

    3 jumper pinouts on R3 Arduino Uno

    ok, so you don't think the pinouts are for jumpers that enable the protocol for the clock and data system...? I know that the board says SDA and SCL on it. I just cant find any written confirmation about board configuration. Its a simple system for simple things, and SCL and SDA are...

    Mercury Outboards

    During the mellenium and just prior to it, all the big businesses were into building the outboard power system of the future which culminated in the "FORCE" outboard. Mercury was extremely determined, and built some real bone headed machines from the 70's to the 90's. On most of their...

    A blender with digital control board fails

    the cuisinart perished.... but the power button led turns on, and the control light flashes... just no motor. So I pulled it apart. The motor has 3J2452 on it and above those numbers is 10H0003. I think the 3J2452 tells me the switching is done at 3 joules and the 2452 is 17hz or something...

    arduino uno R3 schematic and datasheets

    That's not R3.... That's the generic version 1kit. Not Arduino, Arduino Clone or kit. R3 has a programmable chipset.

    3 jumper pinouts on R3 Arduino Uno

    Why would I want to flash the USB bus, and change its operation...?

    3 jumper pinouts on R3 Arduino Uno

    Now I see a small problem with your post after checking, and rechecking to make sure of all this...... You will notice on Bertus post that the two boards are different in a big way, and following what you said, THERE IS AN ICSP PORT ON THE OTHER END OF THE BOARD, so my question is WHY - would...

    3 jumper pinouts on R3 Arduino Uno

    nice personal tag! "Never ask a retard directions...." So I am glad I asked, thank you very much for this data which I probably couldn't have gotten anywhere else than the incredible ELCTRONICSPOINT FORUM !! (like the tag? I knew you would...)

    3 jumper pinouts on R3 Arduino Uno

    Top One... do I need the jumpers or not?

    Arduino Uno R3 or Arduino Mega 2560?

    I only have one thing to say about this. When you build a clone(a duplicate of something), which they encourage at Arduino, you really need to concider physics. That being said, most of the clones were specially designed to perform certain jobs, they can do all the basics and more, but it would...

    3 jumper pinouts on R3 Arduino Uno

    too much microscope eye.... misst the big chip again... just like the big sign at the door. ...... this clone allows me to swap out the chip for different works, it is focused primarily on wireless and IR sensors and controls. I still need to know whether the jumpers need to be there...

    3 jumper pinouts on R3 Arduino Uno

    The 2 images are the same..except the colorful "UNO" tag... duh!! I got the clone... though! Anyway the top of the image on the left side of the pic, right above the AREF reference pinout there is a set of 6 pins that look like jumper setting to me. I can't find any data on them, what they do...

    Force Feedback for i.e. Logitech Yoke

    I grew up in a heavy equipment shop. I have always wanted to build a hydraulic yoke, and I think using stepper motors for force feed back is old news what do you think? Kids toys? overkill?? the object is to make the computer which is just kind of guessing where the yoke is, to understand...

    Please help a lay person with some repair questions

    The new devices are usually not charged circuits, but your device is a medical device so I will throw it in...(not a pro just in the know) Some equipment uses a board that requires a pre-charge to make it work. (explanation) "When its' made, it is plugged into a battery and the boards...
