I. Summary The core concept behind the project and its circuitry involves incrementally rotating a stepper motor by a specific step angle. To accomplish this, the project will employ an ULN2003 IC in conjunction with the L293D Motor Driver. This combination is necessary because the controller lacks the capacity to supply the current demanded by […]

INTRODUCTION The primary objective of this project is to execute the USB protocol and manage the reading and writing of packets of various sizes within the memory of the Peripheral Interface Controller (PIC) microcontroller. Several test cases have been incorporated, which include: – Writing a single packet to the device – Reading and writing a […]

Circuit Breaker Overview A circuit breaker is an electrical switch designed to protect an electrical circuit from damage caused by excessive current flow. It is an essential component in electrical systems and is used to prevent short circuits, overloads, and electrical faults that can lead to fires or damage to equipment. Circuit breakers come in […]

What is a Microcontroller? Microcontrollers are small, standalone computers used to manage operations in electronic devices. They can be found in a wide range of gadgets, including as workplace equipment, robotics, home appliances, cars, and other technology. Due to their employment in powering and controlling CubeSats, tiny satellites used for scientific study and teaching, microcontrollers […]

The SMALpic Assembler When I embarked on a substantial PIC-based project for paid work, I encountered a common issue: most of the PIC tools were designed exclusively for Windows. Additionally, the Linux tools available seemed to require a significant time investment to upgrade my outdated Linux system. However, I already had a capable assembler at […]

The role of power supply is crucial for electronic circuits because without sufficient power, the circuit cannot function at its optimal level. On the other hand, an exceeded power supply can deteriorate the circuit components by heating effect. There are usually two choices for power supply topologies; Linear Power Supply and Switched Mode Power Supply (SMPS). The linear […]

Laser engraving is a common practice of using lasers to engrave anything on an object like designs, photos, any form of data, etc. This drawing tool is now an increasingly adopted tool for small businesses, product designers, makers, as well as hobbyists. A laser engraver machine consists of three main parts: a laser, a controller, […]

Axiomtek – a world-renowned leader relentlessly devoted to the research, development, and manufacture of series of innovative and reliable industrial computer products of high efficiency – is pleased to introduce the GOT815W-511 and GOT812W-511, the 15.6-inch and 12.1-inch stainless steel fanless touch panel computers powered by the Intel® Core™ i5-7300U processor (code name: Kaby Lake). The high-reliability touch panel PCs are […]

The AA and AAA-sized batteries provide power to our everyday handheld devices like radio, remote control, gamepads, synths, etc. Most of these batteries used are non-rechargeable, and one has to dispose of them after their usage. According to a report, more than 80% of zinc-carbon cells end up in a landfill. The improper disposal of the batteries […]

Nanograf in the US has developed a cylindrical lithium-ion cell with an energy density of 800Wh/l using a silicon battery anode. The 18650 format cylindrical lithium-ion cell with a silicon anode developed by Nanograf provides 3.8Ah, 28 percent more power that graphite-based anode technologies. This is a breakthrough for the battery industry,” said Dr. Kurt (Chip) Breitenkamp, president of […]
