We are all aware of the multiprotocol RF shields for Arduino development boards. These RF shields gave RF capabilities to the board and made them compatible with the modules such as RFID, XBee, or Bluetooth. Electrolama, based in the United Kingdom, released a tiny "USB stick"...

An antenna tracking system adjusts the axis of an antenna to follow a moving signal source like a communication satellite. The working of an antenna tracking system is quite simple; the antenna is, first of all, commanded to move in any direction. Then, the level of the received signal...

Lithophanes are artistic creations on ultra-thin translucent porcelain that is visible only when backlit with a light source. They are etched or modeled artworks made by a 2D image. The 2D image is first processed to make its gray-scale representation, and then, depending on the color,...

3D printer controller boards are the brains of any 3D printer. All the electrical components are interfaced with the printer motherboard. The main job of the controller is to follow the code from the 3D printer software and produce a 3D printed object. The controller receives various...

E-paper displays are fascinating. They mimic the appearance of ordinary ink on paper, and they look brilliant! E-Paper displays make reading comfortable and provide a wider viewing angle than most light-emitting displays. An idle E-Paper display can be easily viewed in direct sunlight...

Gel Electrophoresis is a laboratory method used to separate macromolecules like DNA, RNA, or protein according to their molecule size. The molecules to be separated are pushed by an electric field through a gel that consists of pores. First, the macromolecules are loaded into wells at...

LiFePO4 Batteries: An Overview Compact electronic devices rely on concise li-ion battery packs. Lithium iron phosphate battery (LiFEPO4) or LFP battery is a type of lithium-ion battery that uses lithium iron phosphate as a cathode and a graphitic carbon electrode as the anode. LFP...

DC-DC converters are needed in almost every commercial product, whether it is industrial, medical, defensive, automotive, or any other application. These converters are electronic circuits that can convert the DC voltage from one level to another. There are two types of DC-DC...
