The LTC4380 is an ultralow quiescent current (IQ) surge stopper, providing compact overvoltage and overcurrent protection for always-on 4V to 72V electronics in automotive, industrial and avionic systems. The LTC4380 replaces traditional shunt circuits composed of bulky inductors,...

The Module is based on The MCP2200, which is a USB-to-UART serial converter which enables USB connectivity in application that have a UART interface. The device reduces external components by integrating the USB termination resistors. The MCP2200 also has 256-bytes of integrated user...

Bob tipped us with his latest project. It's a 3V3/30V DC/DC converter using SN6505A from TI. Recently I'v got my samples of SN6505A, it's a really nice IC, so I decided to make a simple DC/DC converter to get familiar with it. What I like in this chip is that it can operate on input...

Spikey made his own DIY 32ch FPV 5.8ghz LCD. He writes: If you’re like me, you don like buying stuff that’s ready-to-go, but rather build one yourself. We usually spend more money, but it’s way more satisfying I really didn’t want to buy an overly expensive FPV LCD receiver,...

Dilshan Jayakody build a simple crystal tester based on Colpitts oscillator. He writes: This is simple Colpitts oscillator to test commonly available passive crystals which range between 2MHz to 27MHz. This unit must connect to an oscilloscope and/or frequency counter to get the...

The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock/calendar provides seconds, minutes,...

Teardown & Repair of an Agilent 54845A 1.5GHz 8GS/s Infinium Oscilloscope -...

This video gives you the basics of how to calculate and use a simple resistive current shunt with an analog panel meter to change the current that is needed for a full scale deflection. The notes page for this video can be found here. Using a Current Shunt with a Panel Meter /...
