A team of researchers with members from the University of California and Rice University has found a way to get a flat transistor to defy theoretical limitations on Field Effect Transistors (FETs). In their paper published in the journal Nature, the team describes their work and why they believe it could lead to consumer devices […]

RS485 is often used as physical layer for industrial buses like ModBus, ProfiBus, InterBus, P-Net, BACnet and Bit-Bus. Bus length depends on data rate and can reach as much as 1000m. co Correct function of RS485 transceiver requires return path between GND of particular transceivers. This path can be created by connecting GND to earth
LTM2881 allows RS485 or RS422 communication even in harsh environment. Read More »
This project is a USB Generic Human Interface Device (HID) device based on a PIC microcontroller. It is a USB interface for alphanumeric LCD display where the user as desired can program it. USB interface is implemented by using PIC18F2550 microcontroller ideal for low power (nanoWatt) and connectivity applications that benefit from the availability of

The MCP6V01 auto-zeroed op-amp features an ultra low offset voltage (VOS) and high common mode rejection ratio (CMRR), which makes it applicable to temperature measurement. The MCP6V01 thermocouple auto-zeroed reference design demonstrates how to measure electromotive force (EMF) voltage at the cold junction of the thermocouple in order to accurately measure temperature at the hot

Electronic loads, programmable and with a recovery function are the best choice for dynamic testing simulating real conditions. Usually you don´t test your power supply and you assume it is working well with your equipment. But what if not? Sometimes your equipment fails without any evident reason and it might be because your power supply

Numitron Geekwatch Ich habe den Vergleich zwar schon einmal im ersten Video zu diesem Projekt erwähnt, aber ich finde ihn sehr passend: Jedem Star Wars Fan dürfte ja bekannt sein, dass sich ein Jedi-Ritter im Laufe seiner Ausbildung sein eigenes Lichtschwert bauen muss. Aber wie sieht es mit Geeks aus? Auch ein Geek muss sich
