    My new project

    Hi all of you Im not sure, i thougt it was parallel data I/O from/to the usb contoller, have you checked for a usb controller IC? The connection between the usb controller IC and the dongle is clock and data(its serial). Also there is ground and +5 Volt. The databus between the usb controller...

    My new project

    Hi It's a USB Dongle, and yes, it is plug and play, but only at the computer side, i belive. Isn't there a USB controller, intended for work together with a microcontroller, it will take care of all the interfacing to the Dongle! And the Dongle is cheap! Only about 30 US$ here in sweden, such...

    How to measure main AC 240V?

    Hi A little warning here! If you connect the common ground to the AC Neutral you can get a ground loop, and if you dont do that, you dont measure the true AC line! Also, if you accidently connect the oscilloscopes common ground to the AC live terminal you get a short! This will probably lead to...

    Polyester cap?

    Hi there zgeniez, velcome to this board Any lowleakage , nonpolarized cap will work here! ;D The voltage rating should be at least the supply voltage for safety! ;D ;D Higher voltage usally means lower leakage(at low voltage)(not always) //Staigen

    Total newbie w/ Resistor question

    Hi mark8denny, velcome to this board The resistor is probably a 600 ohms, 1 % tolerance resistor! 1:st ring(stripe) = blue(6) 2:nd ring = black(0) 3:rd ring = black(0) 4:th ring = black(0) this is the multiplier or the amount of zeros after the 3 first rings 5:th ring = brown(1) this is the...

    Re: what is trimmer

    Hi Audioguru, we often think the same, i also saw this and reacted at first, and have to look at the datasheet for the ic, saw that it can work at its negative rail and realized that it must be so ;D //Staigen

    Re: what is trimmer

    Hi there ateso8634, welcome to this forum They mean a trimpot, it is an adjustable potentiometer, usally adjusted with a screwdriver. It usally have 3 connections, but i have seen trimpots with 2 connectors and also(for special purposes) with 4 connectors. So, it is an adjustable resistor //Staigen
