Axiomtek, a Taiwan based company has introduced new Pico-ITX form factor SBCs using Intelâs Apollo Lake processor. This line of SBCs from Axiomtek started with PICO312 with minimal coastline ports, and then followed with a COM-like PICO313. Recently they launched a similar 100 x 72mm PICO316 SBC with more versatile ports than the original PICO312. This PICO316 SBC is

Analog Devices (ADI) has introduced a quad-channel protector and two multiplexers offering ±55V overvoltage protection (OVP) for precision converters, amplifiers and other components that operate from a voltage of 4.5V up to 36V. According to ADI the ADG5462F quad channel protector, ADG5248F 8:1 multiplexer and ADG5249F differential 4:1 multiplexer offer ±55V OVP in power-on and power-off stages

Introduction: This describes my original design dual channel quantizer inspired by Chris Listâs ARP Style CV Quantizer design. My new implementation is an intelligent design that exploits the programmability of a Microchip PIC16F84. It will quantize voltages in 1/12 volt (semitone) or 1 volt (octave) steps from â10V to 10V. Quantization time is about 2ms

Inroduction More and more experiments are now âPC-assisted.â Also conventional acquisition systems are very expensive. Since portable  PCs are today common and a USB link is a better solutionhere we present an oscilloscope using USB port of the PC that operates at up to 10 kHz with ±16V input voltage. It has much more improved features than the PC-based oscilloscope . The oscilloscope uses IC
