there must be a way to key it also from the PC. This is why I decided to embed into the same circuit, a PC keyer which is triggered by the line audio of the PC, but also triggered manually (internal or external key). Keying by audio tones was decided, because modern PCs do not...
Relays use an electromagnet to mechanically switch a circuit on or off, allowing a small amount of electrical power to control a much larger power load. Commonly found in both household appliances and vehicles, relays enable electronic controls to operate high-power circuits like motors and lights...
I have had intermittent success getting my Samsung Galaxy S3 to power the ODAC without a powered hub. I have a generic otg usb cable that seems to work as long as I connect it to the phone while it is busy. I did a phone restart with the usb plugged in and seemed to trick the ph...
the motor moves because the current flowing from your wall socket produces a magnetic field. it's not the electricity itself powering the motor, but the charge the magnet creates. the force of the magnet creates rotational movement, which means it rotates around a fixed point, similar to the...
Whatever the device, you want to connect it to the internet. It would also be nice to share things, like printers or extra disk space, among compatible devices. You, my friend, need a LAN, or Local Area Network. There are lots of ways to set one up; I’ll review the basic setup ...
Too much charge flowing through a circuit at a particular time would heat the appliance's wires and the building's wiring to unsafe levels, possibly causing a fire. This keeps the electrical system running smoothly most of the time. But occasionally, something will connect the hot wire ...
