Digital Buffer The digital buffers are used in digital circuits for the amplification of digital signals in order to drive high current loads. Besides current amplification, the digital buffers provide isolation between input and output circuits where output is connected to some...

When powering many appliances from a sine wave inverter, the HV DC is converted to AC only to be rectified back to DC in the appliance. This inverter eliminates the SPWM stage and outputs DC only. This DC can be used to power appliances, or as a HV DC source for your SPWM, variable...

The new Move-Shoot-Move (MSM) Star Tracker is a device that can be used to capture clean and clear astro pictures. It is compact, easy to setup (in two minutes); and can do time-lapsed movements, 5-minute exposures with no trails, and Polar Alignment. This makes it capable of capturing...

Upward-lighting multicolor LEDs in the CL-V501 Series from Citizen Electronics have improved color mixing, come in a small package, and exhibit high brightness. Multicolor LEDs have three dies of RGB (red, green and blue) in one package. This lets them generate various colors, including...

Exclusive-NOR Gate The Exclusive-NOR logic is the complement (reverse) form of the Exclusive-OR logic. It is the serial combination of Exclusive-OR and the NOT gates. The Exclusive-NOR gate gives an output given by the expression “Both A & B, not A or B”. It means that the output...

What can be better than ESP8266 and ESP32? Maybe a battery-powered ESP32-C3 board designed to provide lower power consumption. LILYGO® has just launched an ESP32-C3 board with a rechargeable 16340 battery holder. The new board, aptly named LILYGO TTGO T-OI PLUS consumes lesser...

Exclusive-OR Gate The Exclusive-OR gate gives an output given by the expression “A or B not Both”. It means that the output of the Exclusive-OR gate is low when both inputs “A” and “B” are at the same logic level i.e. both “HIGH” or “LOW”. In the case of, either...

There had been a spoiler by Sipeed a few weeks back about the testing of yet another Tang Nano board. Yes, you are right, this is not the first Tang Nano board by Sipeed, but the first version came two years ago as a $5 development board built around Gowin GW1N-1 LittleBee FPGA....
