    Soldering dead bug circuits

    Hi there, I have been working on an AM radio test generator. It is from the book ”building your own transistor radios”. I would provide a schematic of the circuit although I believe the copyright would prevent me from doing so. The two ICs used in the circuit are the 74HC14 hex Schmidt...

    How much current can a tin solder track handle?

    I'm working on a DIY project where I need to control some 9V solenoid valves with an arduino. I don't have the tools to make a PCB myself, so i choosed to work on perfboards. Now, I have to connect power supply (MeanWell ) to the step down regulator (Polou D36V50F9) that powers the solenoid...

    What is this? I can't even get the solder to melt.

    I'm simply trying to learn and practice soldering and desoldering. I have an old board i am working on and can't for the life of me get ANY of the components off. I can't even get the solder to melt. Do they use something other than solder during manufacturing? Here is a picture. I have...

    Car multimedia player Ribbon cable repair

    So guys the display ribbon cable on my JVC KD-AVX44 went bad, and I was wondering if I can find something similar, or if it's just a proprietary cable, that only JVC uses. It's a 24 pin ribbon cable with a regular termination on one side, but on the the other it's split into two 12 pin...

    Is this circuit board ruined?

    Is there a way to salvage this part of the board with soldering? When I was trying to unplug the connector that was attached to this board, I accidentally pulled the whole thing off (connector and it's 'housing', instead just the connector). So as you can see the part where the arrow points to...
