ARM processors touch 70% of the global population. From the edge to the cloud, Arm is on track to touch 100 percent of the world’s shared data. Arm has announced Armv9, its first new ARM architecture in a decade. Arm’s solution to the future needs of AI, security and specialized computing is v9 released at →
For a passive summing mixer is a circuit to combine two audio signals to one signal. Passive summing works generally ok, both with unbalanced and balanced circuits if all connected circuits are same type (mixed balaced and unbalanced is mixed business if it works as wanted or not). When the devices connected to all inputs →
Copper interconnections are easy but have speed limits and traditional fiber-optic cables don’t work well directly with the silicon chips. New hair-thin polymer ribbon was able to transmit data on three channels at a speed of 105 gigabit per second over polymer ribbon 30 centimeters long and 0.4 millimeter wide, with far greater energy-efficiency than →
A power supply unit (PSU) is an electronic circuit that converts device input voltage fed to the device being powered to the voltage or voltages needed internally by the electronics device. In typical computers a power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a computer. Depending →
A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, normally 120 V RMS at 60 Hz or 240 V RMS at 50 Hz. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. They range from small →
The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. An ideal power inverter should generate accurate 230V AC 50 Hz or 110V AC 60 Hz power with sine wave waveform. A less ideal inverter typically generates square wave or “modified sinewave” waveform →
A relay power inverter converter simple and easy inverter make circuit to convert 12V to AC voltage that can drive some small 230V AC loads like some low power lamps (LED or fluorescent energy saving bulbs). It is often advertised as a simple and easy electronics diy projects make at home. The basic idea of →
Christmas lights can be a beautiful sight to behold. They can decorate public spaces and homes. Stringing lights outside can be a real safety hazard if you’re not careful. For outdoors use the lights you need to have lights that are designed to be used outdoors. For outside use there are nowadays both consumer and →
An ideal power inverter will produce same kind of power that is available from mains outlet, which typically means sine waveform 60 Hz 11-120V AC or 50 Hz 220-240V AC. That kind of power source can power all mains powered devices as long as enough power is available. Where power inverter devices substitute for standard →
This is a continuation to my Power inverter designs post. The first post was about general details of inverters and square wave inverters. Because square wave inverters are not suitable for many applications. The next better inverter category is so called modified sine wave inverter. Modified sine wave inverters are less complicated than sine wave →
