In the hardware world, we’ve gone through generations of GPUs and processors, but we’re still rocking the same DDR4 RAM that’s been mainstream in PCs for almost seven years. But now it seems that DDR5 is finally coming: DDR5 modules are just around the corner, as production is in full swing and manufacturers are teasing →
Sometimes there are needs to measure mains voltages with oscilloscope. You must be very careful when measuring voltages on the mains with any measurement instrument. The mains voltages are absolutely deadly. Measuring mains voltages with multimeter can be dangerous. Trying to do the measurement of mains voltage with oscilloscope is potentially more dangerous, because typically →
I have had several situations where everything is hum free, but when I disconnect or power down the signal source (smart phone, computer etc..) I start hearing annoying humming noise. The noise goes away when the signal source is plugged in and powered. Latest example was some cheap multimedia speakers connected to USB sound card. →
Traditionally analogue video transmission is done using 75 ohm coaxial cables. Those video signals are not directly compatible with nowadays more widely used twisted pair wiring (CAT5, CAT6 etc..), which means you just can’t wire the signals directly form video output to a twisted pair wire. The main problems in connecting 75 ohms video source →
IBM has become the first in the world to introduce a 2-nanometer (nm) node chip. It claims will improve performance by 45% using the same amount of power.

I saw presentation of Sound Tools XLR Sniffer/Sender at https://www.ratsoundsales.com/mm5/merchant.mvc?Screen=PROD&Product_Code=soundtools-xlr-snifsend It was described: “Quickly troubleshoot faulty mic lines and cables with this set of remote end cable testers. The XLR Sniffers can also utilize phantom power to test snake lines and cables in live environments, making it simple to diagnose issues and get your show →
An audio multicore cable (often colloquially referred to as a multicore, snake cable or snake) is a thick cable which usually contains 4–64 individual audio cables inside a common, sturdy outer jacket. Audio multicore cables are used to convey many audio signals between two locations, such as in audio recording, sound reinforcement, PA systems and →
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 →
