This project is a NiCad-NiMh Battery Monitor based on LM3914 IC DESCRIPTION The simple project can be used as test gear. Its easy way to monitor the battery voltages, especially dry cell, NICAD, NIMH, supply up to 1.5 Voltage. Battery Monitor range 0.15V to 1.5V. The project is built around Texas instruments LM3914, The LM3914 […]
In my previous article, I have made the Bridge Monitoring System using Wireless Sensor Network project, which allows me to display all the related measurements from Arduino on my PC. Therefore, in this article, I am going to explain in details on how to display the Arduino measurements using Laboratory Virtual Instrument Engineering Workbench (LabVIEW). Two analog
This project is a 10W Stereo Audio Amplifier based on TDA1521 IC. DESCRIPTION The project built around Philips TDA1521 IC, The project provides high quality audio 2X10W Audio output. The device is especially designed for mains fed applications, (e.g. Stereo TV Sound and Stereo Radio). The circuit designed for asymmetrical power supply systems. SPECIFICATIONS It has few external
Makers and Arduino enthusiasts searching for a project to keep them busy this weekend may be interested in this awesome Arduino Fibonacci clock created by maker “TecnoProfesor”. may look a little complicated to read the time but once you know how to read it the Fibonacci clock is a great talking piece. Check out the
Word clocks are a cool way to tell the time. While they could have probably been built back in the 1960s with a bunch of relays and bulbs, they really only came into their own in the LED-everything era. [Vatsal Agarwal] built one of his own, showcasing his maker credentials. It’s a build that relies on
How do you hack your motivation? Do you put red marker Xs on a paper calendar every day you exercise? Do you use an egg timer to sprint through dozens of emails? Do you lock all the doors and shut off your data to write some bulletproof code? If you are [Hulk], you build a YouTube
Intel’s first product was not a processor, but a memory chip: the 31011 RAM chip, released in April 1969. This chip held just 64 bits of data (equivalent to 8 letters or 16 digits) and had the steep price tag of $99.50.2 The chip’s capacity was way too small to replace core memory, the dominant

Lithium-sulfur batteries are suitable for both vehicle and grid applications as they are ultra-cheap, high-energy devices. Sulfur is a very low-cost material and the energy capacity is much higher than that of lithium-ion. So, lithium-sulfur is one chemistry that can possibly meet the demand for energy storage at a cheap price. However, the serious problem is, lithium-sulfur
We often write about the growing trend of tech companies to make robots for the purposes of teaching the youth how to code. Today we’re doing that again, but this time telling the story of a local tech start-up doing this rather than some big international company. Because South Africans should also be learning about
Local company builds new bug-like robots to teach programming to schools Continue Reading
