Hey, sorry everyone, I know it’s been a while. But I hope this post will make up for that! Anyone who has done embedded programming knows that an easy way for microcontrollers (like arduino) to connect to a PC is through a serial connection. Unfortunately, not many computers have a serial port these days, and

The Zeta is a minimal Z80 toggle-switch computer. It has a Zilog Z80 microprocessor, 256 bytes of RAM and the only interface is the front panel which directly sets and reads the address and data buses. There is a video of it executing Euclid’s algorithm: https://www.youtube.com/watch?v=0GmY_UrbXnA At the moment, there is only one real source

The LTC®3807 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage. A constant frequency current mode architecture allows a phase-lockable frequency of up to 750kHz. The 50μA no-load quiescent current extends operating run time in battery-powered systems. OPTI-LOOP® compensation allows the transient response to be optimized
When we first encountered the offspring of this Digi-Key/Mentor CAD collaboration, it was still in beta, and the pricing model was unclear. Now that it’s here for real, let’s take a quick look. For more detail: Mentor meets Digi-Key, low-cost CAD results

Hysteresis can be added to a comparator circuit to improve its stability, especially when the input signal is noisy. In this post, we will examine the hysteresis characteristics of some common comparator and Op Amps using an oscilloscope. Perhaps the most intuitive way to visualize the hysteresis in a circuit is to plot the input

The LTC2983 measures a wide variety of temperature sensors and digitally outputs the result, in °C or °F, with 0.1°C accuracy and 0.001°C resolution. The LTC2983 can measure the temperature of virtually all standard (type B, E, J, K, N, S, R, T) or custom thermocouples, automatically compensate for cold junction temperatures and linearize the

RTC or real-time clock is a kind of computer clock for keeping track of the recent or most current time. Commonly, RTCs are present in almost all or any device, which are electronic in nature that needs to keep time accurate. Meanwhile, temperature sensors are devices that gather data concerning the temperature from a source

There’s another promising contender in the race to supplant the dominance of lithium-ion and metal-hydride based batteries in the world of energy storage. New research from the Karlsruhe Institute of Technology’s (KIT’s) Helmholtz Institute Ulm (HIU) details the development of an electrolyte that can be used in new magnesium-sulfur battery cells that would be more
