While most of us are getting more familiar with Internet of Things (IoT) every day, we don't pay attention to the danger which we are exposing at. If you are aware about Internet of Things, you should know about IoT security concerns and what you can...
No, this isn't like the sound of one hand clapping. Several popular ham antennas depend on multiple sections of coax, which act alternately as radiators and delay lines. The velocity of propagation in the delay lines is well known, being 66% for solid...

Got some time today to investigate the behavior of the original circuit, as well as the fix I have proposed. I don't have one ACT chip, unfortunately, only got my hands on a 74'00 from HC, HCT and LS families. Used the s_ntap program by Guillaume...
Introduction I noticed that my LED strip samples have different base thicknesses. Most samples are thin and bend easily; some are thick and hold their shape well after bending. I found only one metal in the strip base. The copper conductors transmit...
The Sipeed Longan Nano development board by Seeed Studio is based on the Gigadevice GD32V which implements the RISC-V architecture. It has an impressive list of features, which you can read for yourself. Low power consumption is claimed as one, a third...
Most clocks use sound to wake you up. This clock is no exception. A little "DFPlayer Mini" module does all of that, also MP3 decoding. It even includes a speaker driver. Yue Xin YX5200-24SS module! Check for short circuit between pin 3 and...
The experiment's point LED luminaires use different connectors to connect the power supply and the light emitter or to extend the wires (for example). Manufacturers and retailers describe the current that can safely pass through the connectors for long...
Samples of LED strips I bought seven types of popular LED strips on Amazon. Three types of COB LED strips and four types of SMD (traditional) LED strips.I'm not explicitly naming vendors because i think this will only mislead the reader. Most brands...
