The 74181 ALU (arithmetic/logic unit) chip powered many of the minicomputers of the 1970s: it provided fast 4-bit arithmetic and logic functions, and could be combined to handle larger words, making it a key part of many CPUs. But if you look at the chip more closely, there are a few mysteries. It implements addition,
72 channels Serial (SPI) to parallel driver board has been designed for various applications. This project can be used as multi Solenoid driver, large size 7 segment display driver, bar graph driver, and LED driver. The project works with 5V logic levels. Output load supply 12V-48V DC and each output can drive 500mA load. I

With the rapid growth of technology, smartphones and e-payments are replacing cards, cash, and wallets. However, developers are still trying to keep wallets relevant in the 21st century, and Volterman is the newest attempts. Besides WiFi hotspot and power bank, Volterman also provides novel security features to protect your phone and wallet from loss. Similar to other
Arduino enthusiasts or those looking to build a DIY binary clock may be interested in a new shield created by developer Marcin Saj. The Arduino binary clock shield has been made available via the Crowd Supply website with preorders starting from $33 and worldwide shipping available from $6, and commencing during August 2019. Watch the overview video
Developers, makers and hobbyists searching for an Arduino powered pneumatic kit may be interested in the Programmable-Air, an Arduino Nano based pneumatics kit which will soon be launching via the Crowd Supply website. Watch the demonstration video below to learn more about the unique Arduino kit and its features. Programmable-Air consists of a built-in high-pressure
Description Solar power is not trivial, especially if it needs to be reliable and have a long lifetime for outdoor deployment such as IoT sensor nodes. This project is an effort to create a complete, easy to use solar power system that provides the following features: – LiFePO4 battery for high charge cycle count, high

I have used E-Ink displays in projects three years ago, but from that time the technology has greatly evolved. That time displays were hard to get, expensive and difficult to use. Now things seem to change with e-ink displays available to the maker market :-). I’m able to get a 128×296 pixel e-paper display for
