The goal of this tutorial is to teach you how to take a circuit drawn in a fabrication program like Altium or Eagle and make it a real-life PCB. To accomplish this we will need about $20-25 and a few hours of spare time. Source: pyroelectro

An indicator is nice, but how to implement that? Because all the intelligence of the heat regulation happens inside the soldering iron, the station itself is just a big 230->24V-transformer and an on/off-switch. Running an extra wire to the soldering iron to sniff out its status wasn’t an option. There is another way to get [...]

Most old PDAs use CCFLs as backlights. While such a PDA itself can still be quite useful, the backlight sometimes is old or damaged. You can, however, replace it with a more modern and power-friendly solution: white leds. To do that in a power-efficient way, a bit more is needed, though. Source: spritesmods

An oscilloscope is a type of electronic test instrument that allows signal voltages to be viewed, usually as a two-dimensional graph of one or more electrical potential differences (vertical axis) plotted as a function of time or of some other voltage (horizontal axis). Although an oscilloscope displays voltage on its vertical axis, any other quantity [...]
