    PCB help

    Hiya. There are two things i need some help with, and they both involve PCB 1. I am fixing an external souncard, where the USB-connector (female) has been torn off. The thing is that I wouldn't know how to go about replacing it. I've removed the old one, however, the place on the PCB where it...

    wireless USB data

    I have a webcamera which is connected to a 7.2V DC source, and i need to transmit the data from this camera to a PC. The range can be up to 1 kilometer away. What is the best way to do this? Does the communication have to be two-way, or is a transmitter by the camera enhough?

    Best circuit drawing software out there?

    I'm looking for 'the best' software to use with electronic circuits. I currently use CircuitMaker, since it allows me to simulate electronics, but on the downside is that the simulation is very limited, and so is the list of components. Does anyone have any recommendations?

    Frequency detection

    As a part of a project i need some sort of frequency detection. Input will be with a microphone, and output would be a digital signal based on the input frequency. For example, if input is 440Hz, a series of ICs would output the binary value 0001. How would one accomplish this? Is there a...

    Homemade Capacitor

    If you need a small capacitor, and you cant find one with the right value, do it the easy (and cheap) way: make it yourself. And it looks alot cooler to :D This consists of paper (regular A4 I found on the floor), some isolating aluminium i pulled out of a cable, the copper from that cable...

    Most interesting electronics-area?

    All of us who like the smell of soldering iron better than flowers, who likes a small electric shock better than a nice massage, who would rather go to an electronics-store than go to the bar, and who thinks 1024 is such a nice round number (ok, im probably just talking about myself, again..)...

    Alternative parts

    In one of the schematics under 'prosjects' (15W FM Transmitter to be precice), a BLY88C transistor is listed under parts.. however, this has proven hard to find where i am (norway).. so is there an alternative that would work just as well?

    50.000V Powersuply

    Me and a friend is currently working on a cool prosject, however, we need a monstrous powersupply.. atleast 30kV DC (preferrably around 50kV). The input voltage is 220V AC. When it comes to amperes, I only need 1A at max.  I've searched for good scematics out there, but i was unable to find any...

    15W Fm-transmitter range?

    Does someone know the aproximate range of an 15W FM transmitter? (And by that i really mean aproximates... 1 meter? 1 kilometer? 1 lightyear?) If nobody knows, atleast help me put things in perspective: Those MP3 players with FM transmitters, how many watts are they? And how many watts are...
