pinko @ blog.exrockets.com wanted to regulate the power to a resistive load so he decided to build a PWM power regulator based on PIC18LF2550. In order to synthesize chlorates and perchlorates in the home lab it is always good to have a way to regulate the current flowing through the...

A lot of project are battery powered and some of them need dual battery links. Robert on hackaday.io had shared his new project that shed light on this issue. He built an load sharing addon board with the ability to charge the battery while the project is operating. Many Chinese...

Researchers have demonstrated the high-performance potential of an experimental transistor made of a semiconductor called beta gallium oxide, which could bring new ultra-efficient switches for applications such as the power grid, military ships and aircraft. The semiconductor is...

Kerry Wong built a 400W/100A electronic load using linear MOSFETs. He writes: I bought a couple of IXYS linear MOSFETs (IXTK90N25L2) a while ago to test their capabilities when used as electronic load, and the result was quite impressive. So I decided to build another electronic...

Sugar Device is a tool designed to control AC Voltage and it promises to change the way you control AC applications forever. Sugar team is targeting hobbyists, students, teachers and engineers to push their application to the next level, since it makes AC control easy, safe and...

Brian Dipert discuss his experience replacing an iphone battery @ edn.com: About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a "this accessory may not be supported" message...

Dual channel Compact  Relay driver module can be controlled by feeding 2-12V trigger voltage, Very useful project for application like Micro-Controller based projects, Remote controller, Lamp on Off, and any circuits which required isolated 5A current and high voltage switching by...
